Request for interpretation of UN R17 for testing of head restraints in cases where the head restraint is not mandatory in the vehicle category in question.

Proposal to clarify the definitions of integrated and detachable head restraints.

Proposal to correct the cross-reference to paragraph 5.11. in paragraph 6.4.3.5. The text should refer to paragraph 5.12.

Proposal transposing the provisions of the draft GTR 7-Amendment 1 (aka Phase 2) into UN R17. Phase 2 addresses a new measurement procedure for the effective height of the head restraint and introduction of the Biofidelic Rear Impact Device (BioRID).

Proposal to amend the dynamic option of the draft 10 series of amendments (document GRSP/2018/34). CLEPA proposes that injury risk limits should be based not only on the injury risk curves, but also on technical feasibility given the repeatability and reproducibility limits of the BioRID II test tool. This proposal also corrects the definition of T(end) which is different from T-HRC.

Proposal to clarify the application of GTR 7 Phase 2 static alternative provisions and to modify the allowed range of tolerances under the backset retention and energy dissipations test. The proposal would re-introduce certain paragraphs in the 09 series of amendments removed by the draft 10 series (GRSP/2018/34). In addition, the proposals adds the area where the gap measurement procedure by the sphere is appropriate per the Federal Motor Vehicle Safety Standard 202a (i.e. only gaps in the area over 540 mm).
