TITLE: FMVSS 208 -- Seating Reference Points

ATTACHMT: ATTACHED TO LETTER DATED 10/31/94 FROM PHILIP R. RECHT TO TREVOR BUTTLE (A42; STD. 208; REDBOOK 2)

TEXT: My responsibility within McLaren Cars at the moment is for the homologation within Europe of the F1 road car.

I have been asked to generate a programme and budget for a possible Federal version of this vehicle, and in that context, I have a specific query on Standard 208. I have been told by Mr. Taylor Vincent that you are the man to contact for this.

My reading of the standard is that passive restraints are required only for the front outboard designated seating positions, and that the front centre designated seating position is required to be fitted with a type 1 or type 2 (active) seat belt. The c onfiguration of the F1 places the driver exactly on the longitudinal centre line of the vehicle, and two rear seats (each provided with a type 2 belt) either side of this position. I believe therefore, that although the driver's seating position is prov ided with a four point harness (i.e. not a type 1 or type 2 belt) for Europe, compliance with the standard is generally demonstrated.

Could you please process this enquiry.

SUBJECT FMVSS 208-SEATING REFERENCE POINTS

With reference to our discussion just now, I am 'faxing drawing 1P0004 which should help with my enquiry.

To clarify, the driver seating reference (R) point is shown as X2175 and the passenger seating reference points are shown as X2495, being therefore 320 mm rearward of the driver reference point. The driver 'R' point is described as "(rearmost)" because the seat has 100mm forward travel from that point, unlike the passenger seats, which are fixed with no adjustment.

For all type approval purposes, the passenger seating positions have been regarded and certified as rear row seats.

Please let me know if you require any further information or back-up data for the enquiry. As I mentioned, I will be on vacation from August 24 until September 7, and in my absence, you should contact Mr. Barry Lett for any technical data.

Thank you for your help thus far.

Best regards
