on a pitch of 75 cm.

2.3. Manikin

 A manikin shall be installed behind each seating position of the seat to be tested as follows:

2.3.1. The manikin shall be placed on the auxiliary seat so that its plane of symmetry corresponds to the plane of symmetry of the seating position in question.

2.3.2. The manikin's hands shall rest on their thighs with  their elbows touching the seat back; the legs shall be extended to the maximum and shall, if possible, be parallel; the heels shall touch the floor.

2.3.3. Each manikin required shall be installed on a seat in  accordance with the following procedure:

2.3.3.1. the manikin shall be placed on the seat as close as  possible to the desired position,

2.3.3.2. a flat rigid surface 76 mm x 76 mm in area shall be  placed as low as possible against the front of the manikin's torso,

2.3.3.3. the flat surface shall be pressed horizontally against  the manikin's torso at a load of between 25 and 35 daN:

2.3.3.3.1. the torso shall be drawn forward by the shoulders to the  vertical position, then laid back against the seat back.  This operation shall be performed twice,

2.3.3.3.2. without the torso moving, the head shall be placed in a  position such that the platform supporting the measuring instruments contained in the head is horizontal and that the median sagittal plane of the head is parallel to that of the vehicle.

2.3.3.4. the flat surface be carefully removed,

2.3.3.5. the manikin shall be moved forward on the seat and the  installation procedure described above repeated,

2.3.3.6. if necessary, the position of the lower members shall be  corrected,

2.3.3.7. the measuring instruments installed shall not in any way  affect the movement of the manikin during impact,

2.3.3.8. the temperature of the system of measuring instruments  shall be stabilized before the test and maintained so far as possible within a range between 19oC and 26oC.

2.4. Impact simulation

2.4.1. The impact speed of the trolley shall be between 30 and  32 km/h.

2.4.2. The deceleration of the trolley during the impact test  shall be in accordance with the provisions shown in Figure 1 below.  Except for intervals totalling less than 3 ms, the deceleration time history of the trolley shall remain between the limit curves shown in Figure 1.

2.4.3. Furthermore, the average deceleration shall be comprised  between 6.4 g and 8.5 g.

3. STATIC TESTS

3.1. Test apparatus

3.1.1. This consists of cylindrical surfaces with a radius of  curvature equal to 82 ± 3 mm and a width:

3.1.1.1. at least equal to the width of the seat-back of each  seating position of the seat to be tested for the upper form,

3.1.1.2.
