 In motor vehicles of category M1 the angle α1 (other than buckle side) shall be within the range of 30 to 80 degrees and the angle α2 (buckle side) shall be within the range of 45 to 80 degrees. Both angle requirements shall be valid for all normal travelling positions of the front seats. Where at least one of the angles α1 and α2 is constant (e.g. anchorage fixed at the seat) in all normal positions of use, its value shall be 60 ± 10°. In the case of adjustable seats with an adjusting system with a seatback angle of less than 20° (see Annex 3, Figure 1), the angle α1 may be below the minimum value (30°) stipulated above, provided it is not less than 20° in any normal position of use.

Where in the case of front seats of vehicles having a maximum vehicle mass not exceeding 3.5 tonnes at least one of the angles α1 and α2 is constant in all normal positions of use, its value shall be 60 ± 10° (e.g. anchorage fixed at the seat).
