Dear Mr. Dobberteen:

This responds to your letter that requested information about how the regulations administered by this agency would apply to a device you wish to market. According to your letter, your company is developing an overhead storage compartment bin to be secured to the interior roof of a utility vehicle behind its rear seat. In a telephone conversation with Marvin Shaw of my staff, you stated that you anticipate that this product will typically be installed in motor vehicles prior to their first consumer purchase. I am pleased to have this opportunity to explain our regulations to you.

By way of background information, NHTSA does not provide approvals of motor vehicles or motor vehicle equipment. Under the National Traffic and Motor Vehicle Safety Act (Safety Act), it is the responsibility of the manufacturer to ensure that its motor vehicles or equipment comply with applicable Federal safety standards. The following represents our opinion based on the facts provided in your letter.

NHTSA does not have any safety standards specifically covering a rear overhead storage bin. However, it is possible that the installation of such a product could affect the compliance of a vehicle with some safety standards.

All new motor vehicles manufactured for sale in the United States must be certified by their manufacturers as complying with the applicable Federal motor vehicle safety standards. If your storage bin is installed in a new vehicle prior to its first sale to a customer, the person making the installation would be considered a vehicle alterer. Under our certification regulation (49 CFR Part 567), a vehicle alterer must certify that the vehicle as altered continues to comply with all applicable Federal motor vehicle safety standards.

Manufacturers, distributors, dealers, or motor vehicle repair businesses modifying a used vehicle are prohibited by Section 108(a)(2)(A) of the Safety Act from knowingly rendering inoperative any safety device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard. Thus, if your storage bin is installed in a used vehicle, any businesses making such installations cannot render inoperative the vehicle's compliance with any of our standards.

We also note that manufacturers of motor vehicle equipment have responsibilities under the Safety Act regarding safety defects. Under Sections 151, et seq., of the Safety Act, such manufacturers must notify purchasers about safety-related defects and remedy the product free of charge.

In order to determine how installation of your storage bin could affect the compliance of a vehicle with applicable Federal safety standards, you should carefully review each standard, including but not limited to Standard No. 216 which addresses roof crush resistance and Standard No. 302 which addresses the flammability of interior materials. In that regard, I am enclosing for your information a fact sheet titled Information for New Manufacturers of Motor Vehicles and Motor Vehicle Equipment, and a booklet entitled Federal Motor Vehicle Safety Standards and Regulations.

I hope this information is helpful. Please feel free to contact Marvin Shaw of my staff at this address or by telephone at (202) 366-2992 if you have any further questions or need additional information.

Sincerely,

John Womack Acting Chief Counsel

Dear Mr. Stewart: This is in reply to your letter of May 8, 1972, as to which component included in a list attached to your letter are subject to the requirements of Motor Vehicle Safety Standard No. 302, 'Flammability of Interior Materials.' A related list was left with Mr. Joseph Zemaitis by Mr. Jim Richardson on April 25, 1972, and our letter responds to this list as well. I would point out that, in line with a suggestion you make, consideration is presently being given to an amendment to the standard which could alter our response regarding some of these components.; Paragraph S4. of Standard No. 302 lists the motor vehicle component subject to the standard. The following components you list appear to be among those specifically enumerated in that paragraph and are accordingly subject to the standard: roof bow silencer (headlining), center arm rest cushion and back boards, tape used in seat assembly, (seat cushions, seat backs), and center pillar trim panels (trim panels).; Plastic roof bows to retain hardboard roof trim seem to be closel related to or a different description of headlining and if so, would also be subject to the standard. In addition, 'a roll bar pad assembly' and steering wheel pads would appear to fall within the phrase, '. . . padding . . . designed to absorb energy on contact by occupants in the event of a crash.' Stereo speaker grills and cones incorporated into a door or rear shelf would be considered part of a 'trim panel' and 'compartment shelf,' respectively.; The following components from your list would not be subject to th standard unless they are '. . .any other materials . . . designed to absorb energy on contact by occupants in the event of a crash': fresh-air deflector, instrument panel end cap, pinch welt, control knobs, transfer case shift lever gasket, dome lamp bezel and lens, 'A'. 'B', 'C', and 'D' post covers, instrument cluster lens, heater/air conditioning distribution ducts, defroster nozzle, defroster and air conditioner outlets, assist straps - door or instrument panel mounted, steering wheel rim material, and wood grain overlay adhered to gauge panel.; The following items that you list are not enumerated in S4.1, and a you state they are not energy absorbing, would not be subject to the standard: front face of instrument panel and glove box door, and cover for steering wheel rims. Finally, based on your description of both roof-silencer pads and dash pads, they would not be subject to the standard.; Yours truly, Richard B. Dyson, Assistant Chief Counsel

Dear Mr. Gupta:

This is in reply to your FAX of August 29, 1994, to Richard Van Iderstine of this agency. For future reference, requests for interpretations of U.S. Federal motor vehicle safety regulations should be addressed to the Office of Chief Counsel.

You have asked whether the size and types of aiming pads you propose to place on headlamps manufactured by Autolite conform to DOT specifications. You describe these headlamps as "a 7" round and a 200 x 142 mm rectangular replaceable halogen sealed beams [which] use a replaceable halogen bulb (HB2)." You enclosed diagrams showing "aiming pad's position as per SAE J1383 - 1992" (Figures 1 and 3), and in the manner you wish to place them on the Autolite lamps (Figures 2 and 4). We understand that these replaceable bulb headlamps are intended to be sold as replacements for sealed beam headlamps of the same dimensions.

Federal Motor Vehicle Safety Standard No. 108 Lamps, Reflective Devices, and Associated Equipment, is the DOT specification that applies to Autolite's headlamps.

The aimability performance requirements for non-sealed beam headlamps are found in S7.8. of Standard No. 108. S7.8 allows any aiming pad pattern that will fit on the headlamp and that will allow any one of the available aiming adapters described in SAE J602 to be used on the headlamp.

Specifically, S7.8.1 in pertinent part allows non- sealed beam headlamps to be equipped with aiming pads to be used with the photometric procedures of SAE J1383 APR85 (not "1992" as you wrote) when being tested for photometric compliance, and to serve for the aiming reference when the lamp is installed on a motor vehicle. S7.8.5 allows an installed headlamp system to

be aimable with an externally applied aiming device. Under S7.8.5.1, this aiming device shall be the equipment specified in SAE Standard J602 OCT80 Headlamp Aiming Device for Mechanically Aimable Sealed Beam Headlamp Units.

You write that the aiming pad sizes and types you wish to use are identical to those on headlamps sold by Hella, and that ETL Testing Laboratories has told you that the aiming pad positions and types meet DOT specifications. This indicates that Autolite's headlamps would be mechanically aimable with SAE J602 equipment, and therefore permissible as meeting Standard No. 108. We recommend that Autolite verify mechanical aimability with SAE J602 equipment before certifying compliance with Standard No. 108.

Our engineering staff has reviewed your letter and asks that we point out the following errors in Autolite's Figures Nos. 2 and 4. Under both Figures, there is a reference to "HB-2 (H4 P43t)." The HB2 light source is not the same as the H4 P43t light source. The HB2 is a light source permitted by Standard No. 108 while the H4 P43t is not permitted by the Standard for motor vehicles. Under the drawing, the dimension "68.5" should be "68.58 +/- 0.51" (see Figure 4-4 of Standard No. 108). The dimensions of "32" and "52.0" must be the sum of two dimension "A"s from Figure 4-4, thus the sum is 42.16 +/- 0.25 + 42.16 +/- 0.25 = 84.32 +/- 0.50, not 84 as nominally calculated. Finally, with respect to Figure 4 only, because this lamp is intended to replace a 200 x 142 mm sealed beam lamp, the position of the aiming pads are not, but should be identical to the 200 x 142 mm sealed beam to facilitate mechanical aim when only one headlamp is replaced.

Sincerely,

Philip R. Recht Chief Counsel

Dear Mr. Tsujishita: This responds to your letter requesting an interpretation of several o our standards. First, I would like to apologize for the delay in this response to your letter. I have set forth the responses in the order you asked the questions in your letter.; 1. Standard No. 105, *Hydraulic Brake Systems*. Paragraph S5.2.1 of this standard provides that the parking brak system on a passenger car and some school buses shall be capable of holding the vehicle stationary (*to the limit of traction on the braked wheels*) for 5 minutes in both a forward and reverse direction on a 30 percent grade. You stated that your understanding of this provision was as follows. During the tests to determine compliance with this provision, the axles of the subject vehicle must be locked by the parking brake. Your understanding is that the vehicle is permitted to slide down the 30 percent grade, and would be considered as complying with this provision of Standard No. 105 no matter how it slides as long as the vehicle's axles do not turn. This understanding is correct.; The parenthetical note in section S5.2.1 was included in the standar to address the situation where a particular 30 percent grade might have a low traction coefficient. In this situation, a vehicle might slide down the grade even though its parking brake system had held the vehicle axles locked for the required amount of time. NHTSA did not intend vehicle sliding because of a loss of traction by the tires to be considered a failure of the parking brake system. To make this intent clear, section S5.2.1 specifies that the parking brake system must hold the vehicle stationary only 'to the limit of traction on the braked wheels.' This language allows the standard not to specify the traction coefficient for the 30 percent grade. Since no particular traction coefficient is specified, compliance testing may be conducted on *any* 30 percent grade that satisfies the requirement of S6.9. That section requires that the parking brake test surface be clean, dry, smooth Portland cement concrete.; 2. Standard No. 110, *Tire Selection and Rims*. Paragraph S4.3 of this standard specifies that a placard containin certain safety performance indication shall be permanently affixed to 'the glove compartment door or an equally accessible location.' You asked if the door latch post, the inner surface of the glove compartment box, and the inward-facing surface of the driver's side door would be considered 'equally accessible locations.' Each of these locations could be equally accessible locations.; In several past interpretations, we have explained that locations fo the placard would be considered equally accessible if two conditions were met. These were:; >>>1. The alternative location must result in the placard bein positioned so that the vehicle operator can readily refer to it, and; 2. The alternative location must keep the placard relatively free fro exposure to substances that could destroy the placard or render it illegible.<<<; If you position the placard on any of your three alternative location so that the vehicle operator can easily refer to it and where the placard would be protected from substances that could destroy it, we would consider each of those alternative locations as 'equally accessible locations' for the purposes of Standard No. 110.; 3. Standard No. 302, *Flammability of Interior Materials*. Paragraph S4.1 of Standard No. 302 sets forth a listing of th components of vehicle occupant compartments that must be certified as complying with the flammability resistance requirements of paragraph S4.3. You listed nine components not specifically listed in paragraph S4.1 and asked whether those components were required to be certified as meeting the flammability resistance requirements. The answer to your question depends on whether the components are designed to absorb energy on contact by occupants in the event of a crash.; Paragraph S4.1 represents a complete listing of all components in ne vehicles that must comply with the flammability resistance requirements. Any component not identified in paragraph S4.1 is not subject to the flammability resistance requirements. The only item on that listing that might be applicable to the nine components about which you asked is 'any other interior materials, including padding and crash- deployed elements, that are designed to absorb energy on contact by occupants in the event of a crash.' Thus, you must determine which of the nine components you asked about are so designed. We would assume that knee bolsters are designed to absorb energy on contact by occupants in the event of a crash. These and any other of the nine components so designed must be certified as complying with the flammability requirements of Standard No. 302. Any of the nine components not designed to absorb energy are not required to comply with the flammability requirements.; 4. Part 575.101. *Consumer Information Regulations, Vehicle Stoppin Distance*.; You noted that S575.101 requires vehicle manufacturers to disseminat information about the minimum stopping distance for groups of passenger cars. Section 575.101(c) requires that each passenger car in the group to which the stopping distance information applies shall be capable of performing at least as well as the information indicates, *under the test conditions and procedures specified in S6 and S7 of Standard No. 105. This specification was added in an amendment published on January 6, 1976 (41 FR 1066). Before that amendment, S575.101 had specified separate test conditions and procedures for the stopping distance information. Those conditions specified that the vehicle's brakes were to be burnished and then the stopping distance was to be measured. In place of those conditions, S575.101(c) now specifies that the stopping distance information should express the *minimum* stopping distances that can be met or exceeded by each vehicle in the group to which the information applies, using the test conditions and procedures of Standard No. 105. Since stopping distances decrease after burnish, the post-burnish results represent the *minimum* stopping distances that can be met or exceeded by the vehicles. Therefore, the pre-burnish stopping distances need not be reflected in the stopping distance information manufacturers make available to consumers.; Sincerely, Erika Z. Jones, Chief Counsel

"Dear Mr. Harpster: This responds to your letter of June 21, 1994 requesting information on whether a 'replacement rear seat used for the transport of prisoners in police cars' complies with the Federal motor vehicle safety standards. During a July 1, 1994 phone conversation with Mary Versailles of my staff, you explained that the seat could be installed either before or after the first retail sale of the police car. I am pleased to have this opportunity to explain our regulations to you. Some background information on Federal motor vehicle safety laws and regulations may be helpful. Our agency is authorized under 49 U.S.C. 30101 et seq. to issue safety standards applicable to new motor vehicles and items of motor vehicle equipment. NHTSA, however, does not approve motor vehicles or motor vehicle equipment, nor do we endorse any commercial products. Instead, each manufacturer is responsible for 'self-certifying' that its products meet all applicable safety standards. The following represents our opinion based on the facts provided in your letter. NHTSA has exercised its authority to establish five safety standards that may be relevant to a prisoner transport seat. The first is Standard No. 207, Seating Systems (49 CFR 571.208), which sets forth strength requirements for all 'occupant seats' in passenger cars. The second relevant standard is Standard No. 208, Occupant Crash Protection (49 CFR 571.208), which sets forth requirements for occupant protection at the various seating positions in vehicles. The third relevant standard is Standard No. 209, Seat Belt Assemblies (49 CFR 571.209), which sets forth strength, elongation, webbing width, durability, and other requirements for seat belt assemblies. The fourth relevant safety standard is Standard No. 210, Seat Belt Assembly Anchorages, which establishes strength and location requirements for seat belt anchorages. The final relevant safety standard is Standard No. 302, Flammability of Interior Materials. This standard specifies burn resistance requirements for materials used in the occupant compartment of motor vehicles. Because federal law operates differently depending on when the installation of the prisoner transport seat occurs, I will separately discuss three possible scenarios. Installation as Original Equipment Standards No. 207, No. 208, No. 210, and No. 302 apply, with certain exceptions that are not relevant to your product, to vehicles and not directly to items of equipment. Thus, the vehicle manufacturer, and not the equipment manufacturer, would be responsible for certifying that the vehicle complies with these standards with the prisoner transport seat installed in the vehicle. Unlike the other four standards, Standard No. 209 applies to seat belt assemblies as separate items of motor vehicle equipment, regardless of whether the belts are installed as original equipment in a motor vehicle or sold as replacements. The manufacturer of the seat belt system provided with the prisoner transport seat is responsible for certifying that the seat belt complies with Standard No. 209. Your letter specifically asks whether the safety belt system installed with the prisoner transport seat complies with all applicable requirements. Currently, Standard No. 208 requires an integral Type 2 (lap and shoulder) seat belt assembly at all forward-facing rear outboard seating positions, and either a Type 1 (lap) or Type 2 seat belt assembly at all other rear seating positions. Standard No. 208 also requires the lap belt portion of the Type 2 seat belt assembly installed at any forward-facing rear outboard seating position to have an emergency locking retractor. Thus, because the seat belt assembly for the prisoner transport seat has a manual retractor, the seat cannot be installed at a forward-facing rear outboard seating position. We note that Standard No. 208 requires emergency locking retractors to ensure improved comfort and convenience for safety belts. The purpose is to make it more likely that the typical vehicle occupant will use his or her safety belts, and also to reduce the likelihood of excessive slack in safety belts during use. You wish to use manual retractors because of special circumstances that arise when the rear seats of police vehicles are used to transport prisoners, i.e., a desire to keep the prisoners solidly restrained in the seats. However, Standard No. 208 specifies the same occupant crash protection requirements for police vehicles as other vehicles, and does not include an exception in this area. A possible solution to your problem may be to install your belt system (with manual retractors) in addition to the safety belts required by Standard No. 208. Provided that the installation did not interfere with the required safety belts, such installation would not affect the compliance of the vehicle with Standard No. 208, since the standard's requirements would be fully met by the original belts. Your belt system would, of course, still have to meet the requirements of Standard No. 209, since it would be considered a 'seat belt assembly.' Installation Prior to First Sale If a prisoner transport seat were added to a new vehicle prior to its first sale, e.g., by the dealer, the person who modified the vehicle would be an alterer of a previously certified motor vehicle and would be required to certify that, as altered, the vehicle continues to comply with all of the safety standards affected by the alteration. Installation After First Sale After the first purchase of a vehicle for purposes other than resale, the only provision in Federal law that affects the vehicle's continuing compliance with an applicable safety standard is set forth in 49 U.S.C. 30122. That section provides that: A manufacturer, distributor, dealer, or motor vehicle repair business may not knowingly make inoperative any part of a device or element of design installed on or in a motor vehicle or motor vehicle equipment in compliance with an applicable motor vehicle safety standard. This provision would prohibit any of the named commercial entities from installing a prisoner transport seat if such installation rendered inoperative the compliance of the vehicle with any applicable safety standard. For example, if the material used in the seat did not meet the burn resistance requirements of Standard No. 302, installation of the system would make inoperative compliance with that standard. Any violation of this prohibition is subject to a potential civil penalty of up to $1,000 for each violation. Please note that this provision does not prohibit owners from modifying their vehicles, even if such modification adversely affects the compliance of the vehicle with safety standards. Thus, if a police department were to modify its own vehicles to install a prisoner transport seat, it would not be a violation of this provision, even if the original belts were replaced by belts with manual retractors. I hope you find this information helpful. If you have any other questions, please contact Mary Versailles at this address or by phone at (202) 366-2992. Sincerely, John Womack Acting Chief Counsel";

You noted that those sections of Standard No. 105 specify both pre-burnish and post-burnish tests, and that the braking performance varies considerable for the two tests. You asked whether the consumer information on stopping distance must reflect the pre-burnish stopping distance. It need not reflect pre-burnish stopping distance.; As you noted, S575.101(c) specifies that the stopping distanc information should be measured under the test conditions and procedures specified in sections S6 and S7 of Standard No. 105. This specification was added in an amendment published on January 6, 1976 (41 FR 1066).

Dear Mr. McCue: This responds to your letter to Mr. Ed Jettner of thi agency concerning an occupant restraint system you have developed to protect medics and attendants in the back of ambulances. I apologize for the delay in our response. The system consists of a vest worn by the attendant which is attached by a tether strap to the ambulance. During an August 23, 1993 phone call with Mary Versailles of my staff, you explained that the tether straps include retractors which lock during a crash. During this phone call you also stated that the back vest can be attached to two tethers on the vehicle wall adjacent to the bench seat, and that the front of the vest is attached to another tether on the opposite wall. You asked for advice on 'how regulations are established and how products are tested to meet standards.' The National Traffic and Motor Vehicle Safety Act (the Safety Act) authorizes this agency to issue Federal motor vehicle safety standards applicable to new motor vehicles and new items of motor vehicle equipment. Section 108(a)(1)(A) of the Safety Act prohibits any person from manufacturing, introducing into commerce, selling, or importing any new motor vehicle or item of motor vehicle equipment unless the vehicle or equipment is in conformity with all applicable safety standards. NHTSA does not approve motor vehicles or motor vehicle equipment, nor do we endorse any commercial products. Instead, the Safety Act establishes a 'self-certification' process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. NHTSA has exercised its authority to establish three safety standards that may be relevant to a vest and tether system for ambulance attendants. The first is Standard No. 208, Occupant Crash Protection, which sets forth requirements for occupant protection at the various seating positions in vehicles. Ambulances, which are classified as multipurpose passenger vehicles under our regulations, are required to have safety belts at each designated seating position. The second relevant standard is Standard No. 302, Flammability of Interior Materials. This standard specifies burn resistance requirements for materials used in the occupant compartment of motor vehicles, including ambulances. The third relevant safety standard is Standard No. 209, Seat Belt Assemblies, which sets forth strength, elongation, webbing width, durability, and other requirements for seat belt assemblies. Standards No. 208 and No. 302 apply, with certain exceptions that are not relevant to your product, to vehicles and not directly to items of equipment. Thus, the vehicle manufacturer, and not the equipment manufacturer, is responsible for certifying compliance to these standards. Standard No. 209, however, applies to seat belt assemblies as separate items of motor vehicle equipment, regardless of whether the belts are installed as original equipment in a motor vehicle or sold as replacements. Standard No. 209 defines a 'seat belt assembly' as 'any strap, webbing, or similar device designed to secure a person in a motor vehicle in order to mitigate the results of any accident, including all necessary buckles and other fasteners, and all hardware designed for installing such seat belt assembly in a motor vehicle.' Thus, your vest and tether system would be considered a 'seat belt assembly,' and the manufacturer of the system would be required to certify that it complies with Standard No. 209 before it could be sold. If the vest and tether system was installed as original equipment by the vehicle manufacturer, the vehicle manufacturer would be required to certify that the vehicle complied with all applicable safety standards with that equipment installed in the vehicle. If the device was added to a new ambulance prior to its first sale, e.g., by the dealer, the person who modified the vehicle would be an alterer of a previously certified motor vehicle and would be required to certify that, as altered, the vehicle continues to comply with all of the safety standards affected by the alteration. I note that in your phone conversation with Ms. Versailles, you stated that your ambulances do have safety belts on the bench seat, however, these do not provide the mobility needed by the attendants when they are caring for a patient. It is our understanding that you intend the vest and tether system to supplement the original safety belts. If your vest and tether system were installed in addition to the safety belts required by Standard No. 208, and provided that the installation did not interfere with the required safety belts, such installation would not affect the compliance of the vehicle with Standard No. 208, since the standard's requirements would be fully met by the original belts. After the first purchase of a vehicle for purposes other than resale, the only provision in Federal law that affects the vehicle's continuing compliance with an applicable safety standard is set forth in section 108(a)(2)(A) of the Safety Act. That section provides that: No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative, in whole or in part, any device or element of design installed on or in a motor vehicle ... in compliance with an applicable Federal motor vehicle safety standard. This provision would prohibit any of the named commercial entities from installing your system if such installation rendered inoperative the compliance of the vehicle with any applicable safety standard. For example, if the material used in your system did not meet the burn resistance requirements of Standard No. 302, installation of the system would render inoperative compliance with that standard. The render inoperative provision does not prohibit owners from modifying their vehicles, even if such modification adversely affects the compliance of the vehicle with safety standards. However, this agency encourages vehicle owners not to make any modifications which would negatively affect the occupant protection systems installed in their vehicles. Also, vehicle modifications by owners may be regulated by state law. In addition to certifying that your vest and tether system complies with Standard No. 209, I urge you to exercise care in evaluating how effective this system would be in an actual crash situation. The original belt system supplied with the vehicle limits the motion of the occupant by keeping the occupant attached to the seat. Your system would have a dual purpose: allowing the attendant sufficient mobility to care for a patient and protecting the attendant in a crash. The tether on your system will not achieve this second purpose if it allows too much motion within the compartment. You may wish to consult a private attorney familiar with the law in the State of Arizona regarding potential liability in tort for your business. I also note that every State provides for some degree of civil liability for consumer products and repair work. I have also enclosed an information sheet that identifies relevant Federal statutes and NHTSA standards and regulations affecting motor vehicle and motor vehicle equipment manufacturers, and explains how to obtain copies of these materials. I hope you find this information helpful. If you have any other questions, please contact Mary Versailles of my staff at this address or by phone at (202) 366-2992.

Dear Mr. Baruth: This is in reply to your letter of August 30, 1971, to Michael Pesko of my staff, concerning Motor Vehicle Safety Standard No. 302, 'Flammability of Interior Materials'. Your letter asks several questions concerning the applicability of the standard to vehicle seats you manufacture. These questions are dealt with individually below.; You first ask whether Standard No. 302 applies to open air tractors earthmoving equipment, or rapid transit seating, or only to ground transportation wherein the people are enclosed by a cab or housing. As stated in paragraph S3. of the standard, it applies to passenger cars, multipurpose passenger vehicles, trucks, and buses. These terms are defined at 49 CFR S571.3, and a copy of this section is enclosed for your information. The vehicles you mention, *i*.*e*., open air tractors, earthmoving equipment, and rapid transit vehicles are generally not vehicles of these types, but if you wish an opinion as to a particular vehicle, you must submit additional information concerning it to us. The criteria you establish, however, 'ground transportation wherein the people are enclosed by a cab or housing' is not an accurate reflection of the specific vehicle types involved, and should not be used as a guideline.; You state that you understand that 'all covering materials, foams thread, welting, etc. used in the construction of a seat is covered', and you are essentially correct, and proceed to ask several questions based on brochures of your product that you forwarded to us. These questions are answered below.; >>>1. *Adhesives*. Adhesives should be tested as part of adjacen materials whenever possible. Both the standard as issued and the notice of proposed rulemaking published May 26, 1971 (36 F.R. 9565) provide for the testing of composite materials, and adhesives joining materials that are to be tested as composites should be tested as part of the composites.; 2. *Seat composite*. Under the present standard, seat composit components that are welded together only at certain points should be treated as composites at the point of weld, and as separate materials between welds, if they are not otherwise uniformly attached to each other at those points. Under the notice of proposed rulemaking of May 26, 1971, however, this configuration would be considered as comprised only of separate materials.; 3, 4, 5. *Bearings, plastic parts and rubber parts, and shoc absorbers*. Components that comprise the seat track or suspension need not meet the standard's burn- rate requirements. Components that are included, however, that are smaller than the sample size specified in S5.2.1 may be tested using the heat-resistant wires specified in S5.1.3.; 6. *Permalator ties*. You describe 'permalator ties' as small diamete wires spaced parallel at about one inch increments, and tied together with hard twisted paper twine that are encapsulated within the foam. As both the wires and the paper twine are incorporated into the foam they must be tested if the particular foam is included within the portions of components set forth in S4.2. Furthermore, they should be tested as part of the foam.; 7. *Paint and decals*. Paint and decals on steel parts that would no be included under S4.1 need not meet the requirements of the standard. Paint and decals on steel parts that are within S4.1 should be tested as part of the steel parts.; 8. *Chassis lubricant*. Seat chassis lubricant is not within th standard's requirements.; 9. *Welting with and without paper core*. Welting with and withou paper core should be tested as part of the material to which it is attached whether it is either, as you mention, extruded vinyl or generated from the parent material. If necessary, it may be tested using the heat-resistant wires specified in S5.1.3.; 10. *Plywood*. Plywood used in seats in seat backs should be teste similarly to other materials used in the same locations.<<<; We are pleased to be of assistance. Sincerely, Lawrence R. Schneider, Chief Counsel

"Dear Mr. Moore: This responds to your letter of February 4, 1994 requesting verification of a statement made by a National Highway Traffic Safety Administration (NHTSA) employee that you are allowed to install passenger seats in a van used for farm transportation if you comply with the safety regulations. In a phone conversation with Mary Versailles of my staff, you explained that you would like to add seats to the rear of a 14 foot cargo van which the nursery owns. You would be performing this work yourself. As explained below, Federal law does not apply to situations where vehicle owners alter their own vehicles. I am pleased to have this opportunity to explain our laws and regulations to you. NHTSA is authorized under the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et seq., Safety Act) to issue motor vehicle safety standards that apply to the manufacture and sale of new motor vehicles and new items of motor vehicle equipment. Section 108(a)(1)(A) of the Safety Act (15 U.S.C. 1397(a)(1)(A)) prohibits any person from manufacturing, introducing into commerce, selling, or importing any new motor vehicle or item of motor vehicle equipment unless the vehicle or equipment item is in conformity with all applicable safety standards. NHTSA has exercised its authority to establish five safety standards which could be relevant to installation of a seat in a used vehicle: Standard No. 207, Seating Systems, Standard No. 208, Occupant Crash Protection, Standard No. 209, Seat Belt Assemblies, Standard No. 210, Seat Belt Assembly Anchorages, and Standard No. 302, Flammability of Interior Materials. Standards Nos. 207, 208, 210, and 302 apply, with certain exceptions that are not relevant to your situation, to vehicles and not directly to items of equipment. Standard No. 209, however, applies to seat belt assemblies as separate items of motor vehicle equipment, regardless of whether the belts are installed as original equipment in a motor vehicle or sold as replacements. Thus, if you install new seat belts on the seats, the manufacturer is required to certify that the seat belts comply with Standard No. 209. If a seat is installed in a used motor vehicle, the seat, as an item of equipment, does not have to comply with any Federal standards. However, 108(a)(2)(A) of the Safety Act provides, in pertinent part: No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative, in whole or part, any device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard. . . . None of these entities could install seats in your van if it caused the vehicle to no longer comply with any of the safety standards. Please note, however, that the 'render inoperative' prohibition does not apply to modifications vehicle owners make to their own vehicles. Thus, Federal law would not apply in a situation where you, as an individual vehicle owner, installed seats in your own vehicles, even if the installation were to result in the vehicle no longer complying with the safety standards. However, you should be aware that individual States have the authority to regulate modifications that individual vehicle owners may make to their own vehicles. While Federal law would not apply to a modification you make to your own vehicle, I nonetheless urge you to exercise care in installing the seats and to install seat belts on the seats. The seats and seat belts will not provide any protection to occupants if they separate from the vehicle frame in a crash. Also, you may wish to consult a private attorney familiar with the law in the State of New Jersey regarding potential liability in tort for your business in these circumstances. I hope you find this information helpful. If you have any other questions, please contact Mary Versailles of my staff at this address or by phone at (202) 366-2992. Sincerely, John Womack Acting Chief Counsel";
