    Dear Mr. Tinto:

    This responds to your request for an interpretation of Federal Motor Vehicle Safety Standard No. 208, Occupant Crash Protection, with regards to adjusting the seat back angle for the low risk deployment tests for the driver. You asked about the order of the seat adjustments for the chin on module test (S26.2) and the chin on rim test (S26.3).

    As you noted in your letter, the same seat adjustment procedure is specified for both tests. S26.2.3 and S26.3.1 read as follows:

    Place the seat and seat cushion in the position achieved in S16.2.10.3.1. If the seat or seat cushion is adjustable in the vertical direction by adjustments other than that which primarily moves the seat or seat cushion fore-aft, determine the maximum and minimum heights of the SCRP at this position, while maintaining the seat cushion reference line angle as closely as possible.Place the SCRP in the mid-height position. If the seat back is adjustable independent of the seat, place the seat back at the manufacturer's nominal design seat back angle for a 50th percentile adult male as specified in S8.1.3.Position any adjustable parts of the seat that provide additional support so that they are in the lowest or most open adjustment position.Position an adjustable head restraint in the lowest and most forward position. (Emphasis added.)

    In your letter, you indicated that the seat back angle may vary depending on when it is adjusted during this procedure.You stated your belief that the adjustment of the seat back angle specified in the fourth (underlined) sentence of this paragraph is conducted after the adjustments specified in the previous sentences, and asked us to confirm that view.

    It is our opinion that the various seat adjustments specified in S26.2.3 and S26.3.1 are to be made in the order specified in those paragraphs.Accordingly, we agree that the adjustment of the seat back angle specified in the fourth (underlined) sentence of this paragraph is conducted after the adjustments specified in the previous sentences.

    I hope this information is helpful.If you have any further questions, please call Edward Glancy of my staff at (202) 366-2992.

    Sincerely,

    Jacqueline Glassman
    Chief Counsel
