Regulation 16.08 Consolidated to Supplement 3 (Revision 10 Amendment 3) (Proposal) Safety-belts, ISOFIX and i-Size Part 10
6.2.5.3.1.1.The locking shall have occurred when the deceleration of the vehicle reaches 0.45 g5 in the case of type 4 or 0.85 g in the case of type 4N retractors.
6.2.5.3.1.2.It shall not lock for values of acceleration of the strap measured in the direction of the extraction of the strap of less than 0.8 g in the case of type 4 or less than 1.0 g in the case of type 4N retractors.
6.2.5.3.1.3.It shall not lock when its sensing device is tilted 12° or less in any direction from the installation position specified by its manufacturer.
6.2.5.3.1.4.It shall lock when its sensing device is tilted by more than 27° in the case of type 4 or 40° in the case of type 4N retractors in any direction from the installation position specified by its manufacturer.
6.2.5.3.1.5.In cases where the operation of a retractor depends on an external signal or power source, the design shall ensure that the retractor locks automatically upon failure or interruption of that signal or power source. However, this requirement need not be met in the case of a retractor with multiple sensitivities, provided only one sensitivity is dependent on an external signal or power source and the failure of the signal or power source is indicated to the driver by optical and/or acoustical means.
6.2.5.3.2. When tested in accordance with paragraph 7.6.2., below, an emergency locking retractor with multiple sensitivity, including strap sensitivity, shall comply with the specified requirements and also lock up when strap acceleration measured in the direction of unreeling is not less than 3.0g.
6.2.5.3.3. In the case of the tests mentioned in paragraphs 6.2.5.3.1. and 6.2.5.3.2. above the amount of strap movement which may occur before the retractor locks shall not exceed 50 mm starting at the length given in paragraph 7.6.2.1. In the case of the test mentioned in paragraph 6.2.5.3.1.2. above locking shall not occur during the 50 mm of strap movement starting at the length given in paragraph 7.6.2.1. below.
