Document title	Proposal for Supplement 4 to the 08 series of amendments to Regulation No. 17
Date	17 Feb 2017			Proposal to clarify the testing of seats with and without head restraints. This proposal would allow alternatives at the request of the manufacturer by clarifying that under testing of a bench seat with three seating positions and two head restraints, a moment of 3 × 373Nm shall be applied to the back of seats and of 2 × 373Nm to the head restraints: (a) If the manufacturer wants to comply with the test requirements of paragraph 6.2. (strength of the seat-back), by the test of head restraint performance of paragraph 6.4., they choose to apply 53 daNm to each seat back without head restraint and 89 daN to each head restraint. In this case only one test shall be performed. (b) If the manufacturer chooses not to apply 53 daNm, during the test of paragraph 6.4., the seat back strength test of paragraph 6.2. has to be performed in addition to the test of paragraph 6.4.
