The test of appendix 5 shall not apply if the rear of the seat cannot be struck by an unrestrained passenger i. In order to verify that the requirements of paragraph 8. In this case, suitable controls means checking the dimensions of the product as well as the existence of procedures for the effective control of the quality of products.
The competent authority which has granted type approval may at any time verify the conformity control methods applicable to each production unit and carry out on samples any test deemed necessary among the tests carried out for the approval. The normal frequency of these verifications shall be once a year. The department may then either:.
Require a further test report from the technical service responsible for conducting the tests. Confirmation or refusal of approval, specifying the alterations shall be communicated by the procedure specified in paragraph 4. If the holder of the approval completely ceases to manufacture a vehicle type approved in accordance with this Regulation, he shall so inform the authority which granted the approval. Upon receiving the relevant communication that authority shall inform thereof the other Parties to the Agreement applying this Regulation by means of a communication form conforming to the model in annex 1 and or annex 2 to this Regulation.
As from the official date of entry into force of the 01 series of amendments, no Contracting Party applying this Regulation shall refuse to grant ECE approvals under this Regulation as amended by the 01 series of amendments. The Parties to the Agreement applying this Regulation shall communicate to the United Nations Secretariat the names and addresses of the technical services responsible for conducting approval tests and of the administrative departments which grant approval and to which forms certifying approval or extension or refusal or withdrawal of approval, issued in other countries, are to be sent.
This requirement shall be considered satisfied if the following biomechanical acceptability criteria for the instrumented manikin, determined in accordance with Appendix 4, are met; that is:. All fittings forming part of the back of the seat or accessories thereto shall be such as to be unlikely to cause any bodily injury to a passenger during impact. The parts of the back of the seat such as adjustment devices for the seat and accessories shall not be subject to any requirements of paragraph 1.
The anchorage on the testing platform provided for the test seat s shall be identified to or have the same characteristics as that used in vehicle s in which the seat is intended to be used. The seat to be tested shall be complete with all upholstery and accessories. If the seat is fitted with a table, it shall be in the stowed position. If adjustable laterally, the seat shall be positioned for maximum extension. If the seat back is equipped with a head restraint adjustable for height, it shall be in its lowest position.
The auxiliary seat may be of the same type as the seat being tested and shall be located parallel to and directly behind the seat being tested. If an auxiliary seat of a different type is used this shall be mentioned in the communication form concerning the approval of a seat type and conformity to the model in annex 1 to this Regulation.
The manikin shall be placed unrestrained on the auxiliary seat so that its plane of symmetry corresponds to the plane of symmetry of the seating position in question. Each manikin required shall be installed on a seat in accordance with the following procedure:. This operation shall be performed twice;. The deceleration or, at the choice of the applicant, acceleration of the trolley during the impact simulation shall be in accordance with the provisions shown in Figure 1 below.
The number of safety-belt anchorage points for the purpose of Test 2 shall be recorded in the communication form concerning the approval of a seat type and conforming to the model in annex 1 to this Regulation.
The auxiliary seat shall be either of the same type as the seat being tested or of a different type, the details of which shall be recorded in the communication form concerning the approval of a seat type and conforming to the model in annex 1 to this Regulation. In the case where Test 2 is conducted with the manikin restrained by a 3-point belt and the injury criteria are not exceeded, the auxiliary seat shall be considered to have met the requirements relating to the static test loads and movement of the upper anchorage during the test specified in Regulation No 14 with regard to this installation.
