TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of March 16, 1971, in which you ask certain questions concerning a child booster seat that you plan to market. You describe the booster seat as a rectangle about 6 inches in height, tapering to 4 inches in the front, and state that it would be advertised for use by children under 50 pounds and would not be designed to fall into the category of child seating systems under Standard No. 213. You also state that your engineers feel a booster chair will "definitely help more five, six and seven year old children to use seat belts simply because these children will be able to see out of a vehicle."

While you state that the booster seat "would not be designed to fall into the category of child seating systems under Standard No. 213," it is not clear from your description of the device that this is actually the case. If you wish an opinion on this matter, we will provide one, but to do so we will need some additional information. Specifically, we will need to know if the booster seat is to be designed or advertised for use with the vehicle seat belts, and if so, how it will be so designed or advertised.

The questions you ask concerning the booster seat are: (1) Can we set a minimum of 50 or 60 pounds? (2) Exactly what is the maximum child weight covered under MVSS #213? and (3) What recommended weight can we advertise as a minimum for our booster seat?

The answers to these questions do not depend on whether the standard applies to your booster seat. If the device is a child seating system, Standard No. 213 does not specify the minimum or maximum heights or weights for children who may use it. Under the standard, it is up to the manufacturer to determine, based upon the design of each particular child seating system, the heights and weights of children for which he recommends the child seating system.

If the device is not a child seating system, the manufacturer is not required to recommend any heights or weights for children who can use it. Should he choose to do so, however, the heights and weights recommended must be consistent with the safe use of the device.

TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of April 9, 1971 concerning certain provisions of Motor Vehicle Safety Standard No. 213, "Child Seating Systems." In your letter you ask whether S4.4 of the standard requires the child seating system itself to be restrained by the seat belt assembly. You state that S4.5.1 indicates to you that the vehicle seat belt assembly is employed to restrain both the child and the seating system, and request that this issue be clarified.

S4.4(a) of the standard requires each child seating system, when installed as the manufacturer directs, to be restrained by the vehicle seat belt assembly. The vehicle seat belt assembly may also be used to directly restrain the child, but it is not required to do so. When it is used for this purpose, however, it must distribute the restraint forces as specified by S4.5.1 of the standard.

The statement in the preamble of the notice of March 23, 1970 to which you refer describes the scope of the standard. This statement means that any device for seating children in a motor vehicle that is designed to utilize the vehicle restraint system or provides restraint by itself, or both, is a "child seating system" and must comply with all the requirements of the standard.

We are pleased to be of assistance.

TEXT: This is in reply to your letter of April 8, 1971, requesting a confirmation of your understanding as to two sections of Standard No. 208, Occupant Crash Protection.

You are correct in reading section S4.3 to provide options for trucks and multipurpose passenger vehicles of more than 10,000 pounds GVWR that differ from the options provided under S4.2 for trucks and multipurpose passenger vehicles with a GVWR of 10,000 pounds or less.

You are also correct in reading S4.2.2 and S4.2.3 to mean "chassis-mount camper" when the term "vehicles carrying chassis-mount campers" is used.

The petitions filed by RVI requesting amendments to Standards No. 208 and 210 are under active consideration and you should expect to receive an answer in the very near future.

TITLE: FMVSR INTERPRETATION

TEXT: This is in response to your letter of January 20, 1971, petitioning for rulemaking pursuant to 49 CFR 553.31, asking that the Tire Identification and Record Keeping Regulation be inapplicable to mobile homes. The points raised in your petition have been thoroughly considered, however, your petition, by copy of this letter, is denied. As you know, many of the points you raised were considered in connection with the interpretation of "Motor Vehicle" as it refers to trailers, issued March 31, 1970 (35 F.R. 5333) (Copy Enclose The interpretation concluded that a mobile home is a motor vehicle within the meaning of the National Traffic and Motor Vehicle Safety Act of 1966, (15 U.S.C. 1381 et seq.). As such, mobile home manufacturer are required to comply with the requirements of Part 574.

The burden placed on the mobile home manufacturer by the regulation does notaappear unreasonable. The regulation requires that the vehicle manufacturer or his designs maintain a record of the tires shipped on or in its vehicles and maintain the names and addresses of the purchasers of its vehicles. Locating the purchaser should be a comparatively easy task.

Mobile homes are constructed with a view, of course, to their over-the-road capabilities. The Tire Identification and Record Keeping Regulation should be applicable to mobile homes since it relates directly to one of the instrumentalities for moving a mobile home. Should a tire sold with a mobile home be defective, we consider it essential that the purchaser of the vehicle be notified of this fact.

TEXT: This is in reply to your letter of March 12, 1971, regarding the March 10, 1971, amendment to Federal Motor Vehicle Safety Standard No. 208, Occupant Crash Protection.

The following are answers to your questions:

1. Question:

Standard to be effective as of August 15, 1973, through August 14, 1975, second option (S4.1.2.2) --- How many dummies should be used for frontal crash? Is the use of dummies necessary for roar and front seats or for front seat only?

Answer:

S4.1.2.2 (b) and (c) specify that the frontal barrier crash requirements of S5.1 shall be met for each front designated seating position. Thus, a dummy must be placed in each front designated seating position for these tests.

2. Question:

Same standard (S4.1.2) --- For a two seater car, what options for passive seat belts for both occupants should be taken? (First or Second option or one of these)

Answer:

A passive belt system may be used to meet the requirements of either the first or the second option under S4.1.2. If the passive belt system is intended to get the second option, however, it must employ a Type 1 seat belt assembly either as a part of the passive belt or as a separate component. This Type 1 belt must be separately usable, and must in addition meet the requirements of S7.1 and S7.2 and have a seat belt warning system.

The risk that the presence of a latch in the system may cause occupants to leave the belt unfastened while the vehicle is in motion is of concern to the NHTSA. At the same time, it is evident that some method of release is necessary for passive belt systems as well as for other passive restraints. We are therefore considering additional rulemaking on the subject of passive belts.

3. Question:

In regard to the Volkswagen Mini bus, which is the category of this automobile? (Multipurpose Passenger or Passenger)

Answer: It in a multipurpose passenger vehicle.

4. Question:

I understand that the convertible type automobile has partial exemption before August 15, 1973. What exception would be taken after that date? Also, through rumor, I have heard that this automobile will be included in the Multipurpose Passenger Car category. Is the correct?

Answer:

Because the multipurpose passenger vehicle may be manufactured in convertible form, the standard refers to convertibles under the multipurpose passenger vehicle requirements. A clear distinction is intended between such convertible multipurpose passenger vehicles, which are regulated by S4.2, and convertible passenger cars, which are regulated by S4.1. There is no plan to treat a convertible passenger car as a multipurpose passenger vehicle.

Convertible passenger cars are not distinguished from other passenger cars other than to exempt them from shoulder belt requirements in the January 1, 1972, to August 14, 1973, time period. They must thereafter meet the passive system requirements applicable to passenger cars, with no special exceptions.(Illegible Word) the multipurpose passenger vehicle category, convertibles are given the option of meeting lesser passive requirements than other multipurpose passenger vehicles (S4.2.2 and S4.2.3).

Please advise us if further clarification is needed.

TEXT: This is in reply to your letter of February 1, 1971, requesting our interpretation of the term "provision" as used in the definition of seat belt assembly anchorage in Standard No. 210 (35 F.R. 18116, November 26, 1970).

The change from the use of the word "device" in the prior issuance of the rule (35 F.R. 15293) to the use of "provision" in the November 26 issuance was made to avoid any appearance of requiring a specific type of structure.

A hole capable of accepting a seat belt assembly's attaching hardware would therefore qualify as an anchorage. It would not, of course, be an anchorage conforming to Standard No. 210 unless it could also withstand the forces specified in that standard.

Please advise us if you have further questions on this matter.

TEXT: This is in reply to your letter of April 19, 1971 and to confirm that if you sell buses to a bus fleet owner, with tires, the name and address of the fleet owner and some means which you can identify the type of tires sold with the bus would be a sufficient record.

In the case where the bus owner purchased the tires from someone other than you, it is not your responsibility to maintain the records, but rather the responsibility of the person selling the tires to the bus fleet owner.
