made on manikins

 The readings of the measuring devices shall be recorded through independent data channels of the following CFC:

2.2.1. Measurements in the head of the manikin

 The resultant triaxial acceleration referring to the centre of gravity ( r)[4] shall be measured with a CFC of 600.

2.2.2. Measurements in the thorax of the manikin

 The resultant acceleration at the centre of gravity shall be measured with a CFC of 180.

2.2.3. Measurements in the femur of the manikin

 The axial compression force shall be measured with a CFC of 600.

3. STATIC TEST

 Forces shall be measured with a CFC of 600   Not Applicable

Annex 7

DETERMINATION OF ACCEPTABILITY CRITERIA

1. HEAD ACCEPTABILITY CRITERION (HAC)

1.1. This acceptability criterion (HAC) is calculated on the  basis of the resultant tri-axial acceleration measured according to annex 6, paragraph 2.2.1. by the following expression:

in which t1 and t2 are any values of time during the test, HAC being maximum value for any interval t1, t2.  The values of t1 and t2 are expressed in seconds.

2. THORAX ACCEPTABILITY CRITERION (ThAC)

2.1. This criterion is determined by the absolute value of  the resultant acceleration, expressed in g and measured according to annex 6, paragraph 2.2.2., and by the acceleration period, expressed in ms.

3. FEMUR ACCEPTABILITY CRITERION (FAC)

This criterion is determined by the compression load expressed in kN, transmitted axially on each femur of

the manikin and measured according to annex 6, paragraph   2.2.3., and by the duration of the compression load, expressed in ms.

Annex 8

PROCEDURE FOR DETERMINING THE "H" POINT AND THE ACTUAL TORSO ANGLE FOR SEATING POSITION IN MOTOR VEHICLES

1. PURPOSE

 The procedure described in this annex is used to establish the "H" point location and the actual torso angle for one or several seating positions in a motor vehicle and to verify the relationship of measured data to design specifications given by the vehicle manufacturer. [5]

2. DEFINITIONS

 For the purposes of this annex:

2.1. "Reference data" means one or several of the following  characteristics of a seating position:

2.1.1. the "H" point and the "R" point and their relationship;

2.1.2. the actual torso angle and the design torso angle and  their relationship;

2.2. "Three-dimensional 'H'  point machine" (3 DH machine)  means the device used for the determination of "H" points and actual torso angles.  This device is described in appendix 1 to this annex;

2.3. "'H' point" means the pivot centre of the torso and  thigh of the 3 DH machine installed in the vehicle seat in accordance with paragraph 4 below.  The "H" point is located in the centre of the centreline of the device which is between the "H" point sight
