TEXT:

This responds to your inquiry about a product known as the "Comfort Cushion" that your organization is testing for compliance with Federal Motor Vehicle Safety Standard No. 302, Flammability of Interior Materials, (49 CFR S571.302). According to the product's packaging that accompanied your letter, the Comfort cushion is intended to be placed over seats in motor vehicles as well as in homes and offices. You stated that a Comfort Cushion you tested did not conform to Standard No. 302. You further stated that the product's manufacturer believes that Standard No. 302 only applies to a car's original equipment and does not apply to an aftermarket auto accessory. I am pleased to have this opportunity to explain our regulations to you.

By way of background information, NHTSA is authorized to regulate the manufacture and sale of new motor vehicles and items of motor vehicle equipment. Section 102(4) of the Safety Act defines, in relevant part, the term "motor vehicle equipment" as:

any system, part, or component of a motor vehicle as originally manufactured or any similar part or component manufactured or sold for replacement or improvement of such system, part, or component or as any accessory, or addition to the motor vehicle...

In determining whether an item of equipment is considered an accessory, NHTSA applies two criteria. The first criterion is whether a substantial portion of the expected use of the item is related to the operation or maintenance of motor vehicles. We determine a product's expected use by considering product advertising, product labeling, and the type of store that retails the product, as well as available information about the actual use of the product. The second criterion is whether the product is intended to be used principally by ordinary users of motor vehicles. If the product satisfies both criteria, then the product is considered to be an "accessory" and thus is subject to the provisions of the Safety Act.

Applying these criteria to the Comfort Cushion, it appears that this product would be an accessory and thus an item of motor vehicle equipment under the Safety Act. Based on our understanding of the product, it appears that a substantial portion of the expected use of the Comfort Cushion will be during motor vehicle operations. In addition, it appears that the product would typically be used by ordinary users of motor vehicles since it is intended to be placed over the vehicle's seats.

While it appears that the Comfort Cushion is an item of motor vehicle equipment, NHTSA has not issued any standards setting forth performance

requirements for such a device. Standard No. 302 would not apply to the device because that standard applies to new motor vehicles and not to aftermarket items of motor vehicle equipment.

However, there are other Federal laws that indirectly affect the manufacture and sale of the Comfort Cushion. The manufacturer of the product is subject to the requirements in sections 151-159 of the Safety Act concerning the recall and remedy of products with defects related to motor vehicle safety. In the event that the manufacturer or NHTSA determines that the product contains a safety related defect, the manufacturer would be responsible for notifying purchasers of the defective equipment and for remedying the problem free of charge.

A commercial business that installs the Comfort Cushion would be subject to provisions of the Safety Act that affect whether the business may install the product on a vehicle. Section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397 (a)(2)(A)) 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.

Any violation of this "render inoperative" prohibition would subject the violator to a potential civil penalty of up to $1,000 for each violation. A manufacturer, distributor, dealer, or motor vehicle repair business that installs an aftermarket item of rapidly burning material could vitiate the compliance of the materials that were present in the vehicle at the time of the vehicle's sale to the first consumer. Such an installation could constitute a possible violation of the render inoperative prohibition.

Please note also that the render inoperative prohibition does not apply to modifications vehicle owners make to their own vehicles. Thus, Federal law would not apply in situations where individual vehicle owners install the Comfort Cushion in their own vehicles, even if the installation were to result in the vehicle no longer complying with the safety standards. However, individual States have the authority to regulate modifications that individual vehicle owners may make to their own vehicles.

I hope this information is helpful. If you have any further questions about NHTSA's safety standards, please feel free to contact Marvin Shaw of my staff at this address or by telephone at (202) 366-2992.
