"Dear Mr. Takacs: This responds to your letter of September 21, 1993 i which you referred to this agency's final rule amending Federal Motor Vehicle Safety Standard (FMVSS) No. 222, School Bus Passenger Seating and Crash Protection, dated September 3, 1993 (58 FR 46873). You requested our interpretation of that notice as to whether the following is acceptable: 1. The webbing Kinedyne uses in its wheelchair strap assemblies is industrial-type 1 or 2-inch polyester webbing that meets the strength and other requirements of S4.2 of FMVSS 209. 2. The hardware Kinedyne uses on its wheelchair strap assemblies are industrial-type 1 or 2-inch overcenter, ratchet or cam buckles, wire hooks, snap hooks and track fittings, all of which meet the strength and other requirements of S4.3 of FMVSS 209. With regard to the webbing used in your strap assemblies, paragraph S4.2(a), FMVSS 209, provides that seat belt webbing cannot be less than 1.8 inches in width 'except for portions that do not touch a 95th percentile adult male with the seat in any adjustment position and the seat back in the manufacturer's nominal design riding position . . . .' That means that seat belt webbing must be 1.8 inches in width only where it touches the person of the occupant. The width of webbed belts or straps which secure a wheel chair to the bus floor and do not touch the person of the occupant is not specified in any standard. Accordingly, Kinedyne is free to use belts of 1 inch or some other width, so long as such belts do not touch the person of the occupant and meet the other requirements of S4.2, FMVSS 209. S4.3 of FMVSS 209 addresses a number of requirements for seat belt hardware, including corrosion and temperature resistance, attachment hardware, buckle release, adjustment force, retractor requirements (if applicable), etc. If the hardware Kinedyne uses in fact meet all those requirements, then it would be acceptable. I hope this information is helpful to you. If you have any further questions or need any further information, please feel free to contact Walter Myers of my staff at this address or at (202) 366-2992. Sincerely, John Womack Acting Chief Counsel";
