1. SCOPE

1.1.

This Regulation applies to:

(a)	Passenger seats for forward-facing installation in vehicles of categories M2 and M3, of Classes II, III and B (1);

(b)	Vehicles of categories M2 and M3 of Classes II, III and B (1) in respect of their passenger seat anchorages and seat installation.

(c)	It does not apply to rearward-facing seats or to any head restraint fitted to these seats.

1.2.

At the request of the manufacturer, vehicles of category M2 (1) approved to Regulation No 17 shall be deemed to meet the requirements of this Regulation.

1.3.

Vehicles where some seats benefit from the derogation provided in paragraph 7.4 to Regulation No 14 shall be approved to this Regulation.

1.4.

The installation of side-facing seats shall be prohibited in vehicles of categories M2 (of class II, III and B) and M3 (of class II, III and B).

1.5.

At the request of the manufacturer and in agreement with the Technical Service, as well as the Type Approval Authority of the Contracting Party, an approval may be granted for vehicles of category M3 (of Class III or B) of a technically permissible maximum laden mass exceeding 10 tonnes with side-facing seats on condition that these side-facing seats are grouped together at the rear of the vehicle to form an integrated saloon of up to 10 seats. Such side-facing seats shall be fitted with, at least, a head restraint and a two-point belt with retractor type-approved in accordance with Regulation No 16. Further, the anchorages for their safety belts shall comply with dimensional and strength requirements based on those as laid down in Regulation No 14. However it shall be taken into account that the seat is side-facing instead of forward-facing, and test and inspections shall not be waived on that basis. The communication document (Annex 2) shall bear the remark stating that side-facing seats have been permitted according to this paragraph. Such approvals shall not be granted anymore as from 1 November 2014 or as from the date of adoption of uniform test provisions for side-facing seats (i.e. this Regulation) as well as provisions for such seats regarding safety-belt anchorages (i.e. Regulation No 14) and vehicles equipped with safety-belts (i.e. Regulation No 16), whichever date is earlier.

1.6.

Paragraph 1.4 shall not apply to ambulances or to vehicles intended for use by the armed services, civil defence, fire services and forces responsible for maintaining public order.

1.7.

Paragraph 1.4 shall not apply to vehicles of category M3 (of class II, III and B) of a technically permissible maximum laden mass exceeding 10 tonnes with side-facing seats provided the requirements of paragraph 7.4 are met.

Appendix 4

DETERMINATION OF ACCEPTABILITY CRITERIA

1. FRONTAL IMPACT (FORWARD-FACING SEAT)

1.1. Head acceptability criterion (HIC)

1.1.1.

This injury criterion (HIC) is calculated on the basis of the resultant triaxial acceleration measured according to Appendix 3, paragraph 2.2.1 by the following expression:

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

1.2. Thorax acceptability criterion (ThAC)

1.2.1.

This criterion is determined by the absolute value of resultant acceleration, expressed in g and measured according to Appendix 3, paragraph 2.2.2, and by the acceleration period, expressed in ms.

1.3. 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 Appendix 3, paragraph 2.2.3, and by the duration of the compression load, expressed in ms.

2. SIDE IMPACT (SIDE-FACING SEAT)

2.1. Head acceptability criterion (HIC) see above paragraph 1.1.

2.2. Thorax acceptability criterion

2.2.1.

Chest deflection: the peak chest deflection is the maximum value of deflection on any rib as determined by the thorax displacement transducers.

2.2.2.

Viscous criterion (VC):

The peak viscous response is the maximum value of VC on any rib which is calculated from the instantaneous product of the relative thorax compression related to the half thorax and the velocity of compression derived by differentiation of the compression. For the purposes of this calculation the standard width of the half thorax rib cage is 140 mm.

where D (metres) = rib deflection

The calculation algorithm to be used is set out in Regulation No 95, Annex 4, Appendix 2.

2.3. Abdomen acceptability criterion

The peak abdominal force is the maximum value of the sum of the three forces measured by transducers mounted 39 mm below the surface on the crash side.

2.4. Pelvis acceptability criterion

The pubic symphysis peak force (PSPF) is the maximum force measured by a load cell at the pubic symphysis of the pelvis.
