Presentation detailing non-compliance issues identified in child seat belt guides and inflatable child seat systems.

Request for guidance in order to resolve conflicting interpretations of paragraph 7.1.4.2.2. The paragraphs reads, " The vertical component of the acceleration from the abdomen towards the head shall not exceed 30 g except during periods whose sum does not exceed 3 ms.” However, an explanatory note for Technical Services on performing the tests under Annex 15 adds, "The wording of this paragraph [7.1.4.2.2.] refers to accelerations representing tensile loads in the spine of the dummy.” Differing interpretations have resulted in a CRS being approved but then rejected during Conformity of Production review by a separate Technical Service.
