Dear Mr. Bohmer: This responds to your February 25, 1977, letter asking whether you motor home conversions make you a manufacturer or an alterer for purposes of compliance with the regulations of the National Highway Traffic Safety Administration (NHTSA).; In your conversion of motor homes, you install used bodies on ne chassis. The NHTSA considers the mounting of a used body on a new chassis to be the manufacture of a new motor vehicle that requires certification. This makes you a manufacturer rather than an alterer. The rules for certification are found in Part 567, *Certification*, and Part 568, *Vehicles Manufacturer in Two or More Stages*. I have enclosed copies of these regulations for your information.; Your second question asks whether the converted vehicle must compl with Standard No. 302, *Flammability of Interior Materials*, even though the original body was manufactured prior to the effective date of the standard. Vehicles must comply with all standards in effect on the date of their manufacture. For vehicles that you complete by mounting a body on a new chassis, you are permitted to treat as the date of manufacture, the date of manufacture of the incomplete vehicle (as defined in Part 568), the date of final completion of the vehicle, or a date between those two dates. Therefore, it appears that the vehicle you manufacture would be required to comply with Standard No. 302.; Sincerely, Frank Berndt, Acting Chief Counsel

Dear Mr. Hardesty: This is in reply to your letter of October 11, 1972, concerning th application of Motor Vehicle Safety Standard No. 302, 'Flammability of Interior Materials'. You ask whether the following components are subject to the requirements of the standard: horn buttons, decorative medallions, control knobs and handles, instrument dials and faces, break resistant mirrors, and lighting fixture lenses or diffusers.; The components that must meet the requirements of the standard ar listed in Paragraph S4.1. None of the components you have asked about are specifically listed in Paragraph S4.1, and normally will not be subject to the requirements. However, components may nevertheless be covered to the extent that they contain materials 'that are designed to absorb energy on contact by occupants in the event of a crash,' or to the extent that they form part of a component listed under Paragraph S4.1. For example, we might consider a decorative medallion that forms part of the surface of a front or side panel to be incorporated into the panel and therefore subject to the standard.; In answer to your request for 'the text of the proposed amendment...i preparation which will establish numerical size...and some information on when it will be incorporated into MVSS- 302.' I have no public information on this subject at this time.; Yours truly, Richard B. Dyson, Assistant Chief Counsel

Dear Mr. Messina: This responds to your December 10, 1976, letter asking whether Standar No. 302, *Flammability of Interior Materials*, applies to the living area of motor homes and mobile homes.; The National Highway Traffic Safety Administration (NHTSA) no longe regulates mobile homes. The National Mobile Home Construction and Safety Standards Act of 1974 (42 U.S.C. 5401 et seq.) ('the Mobile Home Act') established within the Department of Housing and Urban Development a comprehensive program for the regulation of mobile homes. We have concluded that one result of that statute's enactment was the implied repeal of the NHTSA's authority with respect to mobile homes. Accordingly, we consider that the enactment had the effect of amending the Vehicle Safety Act's definition of 'motor vehicle' to exclude 'mobile homes' as the latter term is defined in the Mobile Home Act.; A motor home, on the other hand, is classified as a multipurpos passenger vehicle (or a bus if it is designed to carry more than 10 persons) and is subject to the requirements of Standard No. 302. The standard mandates that certain enumerated components located within the vehicle occupant compartment meet specified burn test requirements. The living area of a motor home constitutes part of the vehicle occupant compartment, and therefore, any component listed in S4.1 of the standard and situated within the living area must comply with the standard.; Sincerely, Frank A. Berndt, Acting Chief Counsel

Dear Mr. O'Reilly: This is in response to your letter of February 13, 1975, in which yo ask whether zippers fall under the purview of Federal Motor Vehicle Safety Standard No. 302.; S4.1 of the standard states that the following components of passenge cars, multipurpose passenger vehicles, trucks, and buses must meet its requirements:; >>>Seat cushions, seat backs, seat belts, headlining, convertible tops arm rests, all trim panels including door, front, rear, and side panels, compartment shelves, head restraints, floor coverings, sun visors, curtains, shades, wheel housing covers, engine compartment covers, mattress covers, and 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.<<<; To the extent that a zipper is a part of any of these components, i would fall within the ambit of the standard. While recreational vehicles are not currently covered by Standard No. 302, the National Highway Traffic Safety Administration issued on November 15, 1974, a Notice of Proposed Rulemaking to extend the coverage of the standard to include recreational vehicles (copy enclosed).; You should also be aware that other rulemaking relevant to the coverag of the standard is underway and will soon be published in the *Federal Register*. For this reason, we recommend you subscribe to either the Government Printing Office Safety Standard subscription service or an equivalent commercial service as detailed in the enclosure.; Sincerely, James C.

Dear Mr. Eckstein: This is in reply to your letter of August 27, 1971, which was forwarde to this office October 20, 1971, by the Federal Trade Commission, regarding Government specifications for retreaded tires. You refer to problems you believe result from 'out of roundness,' specifically, abnormal wear and blowouts at normal boulevard and highway speeds. You wish to determine whether this problem results from 'too lenient' Government requirements, or whether 'manufacturers are negligent.'; Out-of-roundness can occur in a retreaded tire for numerous reasons and its presence does not necessarily indicate negligence on the part of the manufacturer. Moreover, while an out-of-round tire may affect vehicle handling it generally does not blow out at normal boulevard or even highway speeds, as result of the out-of-round condition. Thus, a blow out in an out-of-round tire could have resulted from other factors. Many tire dealers, in addition, have machines that can eliminate out-of-roundness by cutting of excess tread.; With reference to Federal regulations of retreaded tires, the firs such regulation will become effective January 1, 1972. This regulation, Motor Vehicle Safety Standard No. 117, 'Retreaded Pneumatic Tires,' specifies size and performance requirements for retreaded tires for use on passenger cars. There requirements are similar to those that have been applicable to new passenger car tires since January 1, 1968. None of these requirements specifically concern 'out-of-roundness.' We do not have evidence that this characteristic, by itself, is a safety problem.; Sincerely, Richard B. Dyson, Assistant Chief Counsel

Dear Mr. Schuld:

This responds to your letter asking for information concerning the application of Federal safety standards to your manufacture of a jump seat that you said would be "removable and able to be transferred from one truck to another." I apologize for the delay in responding. Generally, Federal motor vehicle seating standards apply to motor vehicles prior to their first purchase by a consumer, and not to "aftermarket" seating components added to a vehicle after such purchase. However, several of our safety standards could apply to your product if the seat is installed in a new vehicle prior to the vehicle's first sale to a consumer. Federal law would also affect your installation of the jump seat in new or used vehicles.

By way of background information, the National Highway Traffic Safety Administration (NHTSA) is authorized by the National Traffic and Motor Vehicle Safety Act to issue Federal motor vehicle safety standards that set performance requirements for new motor vehicles and items of motor vehicle equipment. NHTSA is not authorized to certify or approve motor vehicles or motor vehicle equipment for compliance with our Federal motor vehicle safety standards. Instead, under the National Traffic and Motor Vehicle Safety Act (copy enclosed), each manufacturer of a motor vehicle or item of motor vehicle equipment is responsible for certifying that its products meet all applicable safety standards. The following represents our opinion based on the information provided in your letter.

There is currently no Federal motor vehicle safety standard that is directly applicable to a removable jump seat sold directly to a consumer. Federal seating standards generally apply only to completed new motor vehicles and not to items of equipment such as a removable jump seat. However, as a manufacturer of motor vehicle equipment, you are subject to the requirements in sections 151-159 of the Safety Act concerning the recall and remedy of products with defects relating to motor vehicle safety. I have enclosed an information sheet that briefly describes those responsibilities. In the event that you or NHTSA determines that your jump seats contain a safety related defect, you would be responsible for notifying purchasers of the defective equipment and remedying the problem free of charge.

If your product will be installed on a new vehicle prior to the vehicle's first sale to a consumer, then the manufacturer of the vehicle will have certain responsibilities relating to its obligation under the Safety Act to certify the new vehicle as meeting all applicable Federal motor vehicle safety standards. Federal standards for seating systems (Standard No. 207) and crash protection (Standard No. 208) apply to designated seating positions in new vehicles. While these standards do not apply to auxiliary seating accommodations (e.g., temporary or folding jump seats), the determination must be made whether your apparatus falls into this latter category and is thus excluded from coverage. Unfortunately, information provided in your letter did not describe your jump seat in sufficient detail for us to offer an opinion as to whether your particular seat is an auxiliary seating accommodation. Photographs or engineering diagrams of your product would assist us in determining whether the seat would be considered an auxiliary seating accommodation, and thus excluded from coverage under Standard Nos. 207 and 208 if installed on new vehicles.

Another Federal standard to which the vehicle manufacturer must certify its vehicle as conforming is Standard No. 302, Flammability of Interior Materials. This standard establishes flammability requirements that must be met by certain vehicle components including seat cushions and seat backs on any occupant seat installed in a new vehicle prior to the vehicle's first sale to a consumer. A manufacturer installing your jump seat on a new vehicle would thus be required to ensure that any seat cushion or seat back on your product conforms to the flammability resistance requirements of the standard.

You should also be aware that there are statutory considerations that affect the installation of your jump seats in new and used vehicles. Section 108(a)(2)(A) of the Vehicle Safety Act specifies: "No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative ... 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 ..." This section requires manufacturers, distributors, dealers or motor vehicle repair businesses (i.e., any person holding him or herself out to the public as in the business of repairing motor vehicles or motor vehicle equipment for compensation) installing the jump seat to ensure that the addition of the apparatus would not negatively affect the compliance of any component or design on a vehicle with applicable Federal safety standards. For example, the commercial entity must ensure that the addition of the jump seat does not degrade from the safety of existing seating or occupant protection systems on the vehicle. Section 109 of the Act specifies a civil penalty of up to $1,000 for each violation of 108.

In summary, removable jump seats sold to motor vehicle owners as items of aftermarket equipment are not subject to any Federal motor vehicle safety standard. The seat could be subject to Federal standards for seating performance and occupant crash and flammability protection if it is installed on new vehicles prior to the vehicle's first sale. Commercial businesses are prohibited from installing the jump seat if the result renders inoperative the compliance of requisite safety components or designs with Federal safety standards. Individual owners, however, are not covered by 108(a)(2)(A) and may themselves install the jump seat in their vehicles without regard to the rendering inoperative prohibition of the Safety Act. To repeat, you as the equipment manufacturer would be obligated to recall and remedy seats that contain a defect related to motor vehicle safety, even if the seats were installed by vehicle owners themselves.

Please feel free to contact us if you have further questions.

Sincerely,

Erika Z. Jones Chief Counsel

TITLE: None

ATTACHMT: Attached To Letter Dated 12/4/93 From David Fabrycky To NHTSA Chief Counsel (OCC-9433)

TEXT: Dear Mr. Fabrycky:

This responds to your letter about an aftermarket product you wish to manufacture. The product is a child safety seat buckle shield, which is intended to prevent a child from opening the buckle on a child restraint system. You state that your device wou ld cover the buckle and prevent the child from gaining access to the pushbutton of a child seat buckle. To depress the pushbutton, the device requires that a latch be actuated and the cover pivoted away from the buckle. You indicated that the device re quires "manual dexterity to exert the forces in many directions simultaneously."

Although we understand your concern that young children not be able to easily unbuckle a child safety seat, we have reservations about devices that interfere with the unbuckling of the seats. I hope the following discussion explains those reservations a nd answers the questions in your letter about the effect of our regulations on your product.

Our agency has the authority to issue safety standards applicable to new motor vehicles and new items of motor vehicle equipment. We have exercised this authority to establish Safety Standard No. 213, "Child Restraint Systems," which applies to all new child restraint systems sold in this country. However, Standard 213 does not apply to aftermarket items for child restraint systems, such as your buckle shield. Hence, you are not required to certify that this product complies with Standard 213 before selling the product.

Additionally, you are not required to get "approval" from this agency before selling the buckle shield. NHTSA has no authority to "approve" motor vehicles or motor vehicle equipment, nor do we endorse any commercial product. Instead, the National Traff ic and Motor Vehicle Safety Act establishes a "self-certification" process under which each manufacturer is responsible for certifying that its products meet our safety standards. The agency periodically tests vehicles and equipment items for compliance with the standards, and also investigates alleged safety-related defects.

2

Although we do not have any standards that directly apply to your product, there are several statutory provisions that could affect it. Manufacturers of motor vehicle equipment such as your buckle shield are subject to the requirements in sections 151-1 59 of the Safety Act concerning the recall of products with defects related to motor vehicle safety. The agency does not determine the existence of safety defects except in the context of a defect proceeding, and thus is unable to say whether your produ ct might or might not contain such a defect. However, the agency is concerned that people be able to easily and quickly operate a child safety seat buckle in an emergency. As the agency said in a rule on the force level necessary to operate child restr aint buckles:

The agency's safety concerns over child restraint buckle force release and size stem from the need for convenient buckling and unbuckling of a child and, in emergencies, to quickly remove the child from the restraint. This latter situation can occur in instances of post-crash fires, immersions, etc. A restraint that is difficult to disengage, due to the need for excessive buckle pressure or difficulty in operating the release mechanism because of a very small release button, can unnecessarily endanger the child in the restraint and the adult attempting to release the child. (50 FR 33722; August 21, 1985)

It appears that your product could significantly increase the difficulty of using the buckle release and thus hinder a person attempting to release the belt in an emergency.

In addition, use of your product could be affected by section 108(a)(2)(A) of the Safety Act. That section prohibits commercial businesses from knowingly tampering with devices or elements of design installed in an item of motor vehicle equipment, such as a child safety seat, in compliance with the Federal motor vehicle safety standards. In determining the effect of a buckle shield on a child seat's compliance with Standard 213, NHTSA would evaluate the performance of the seat with the buckle shield i nstalled. Standard 213 specifies several elements of design with which a child restraint system is unlikely to comply if your buckle shield were installed. Section S5.4.3.5 of Standard 213 requires the pushbutton release for any buckle on a child restr aint to have a minimum area for applying the release force. Since your device will completely cover the buckle when installed, the buckle shield would cause the child restraint to no longer comply with this requirement. That section also requires the b uckle to release when a specified maximum force is applied. Your device will not allow the buckle to release when the force is applied because it will cover the buckle and require force to be applied "in many directions simultaneously." Your device woul d thus cause the child restraint to no longer comply with that requirement. Therefore, commercial establishments cannot

3

legally install your device on customers' child safety seats. In addition, section S5.7 of Standard 213 requires each material used in a child restraint system to comply with the flammability resistance requirements of Standard 302, "Flammability of Int erior Materials." If your buckle shield does not comply with the requirements of Standard 302, commercial establishments cannot legally install your device.

The prohibition of section 108(a)(2)(A) does not apply to individual vehicle owners who may install or remove any items on child restraint systems regardless of the effect on compliance with Standard 213. However, our policy is to encourage child restra int owners not to tamper with or otherwise degrade the safety of their child restraints.

I hope this information is helpful. If you have any further questions, please contact Ms. Deirdre Fujita of my staff at this address or by telephone at (202) 366-2992.
