Automatically-locking retractors Sample Clauses
The 'Automatically-locking retractors' clause defines the requirement for seatbelt systems in vehicles to include retractors that automatically lock in place during sudden stops or collisions. These retractors allow the seatbelt to extend and retract freely during normal movement, but instantly lock to restrain the occupant when a rapid deceleration or impact is detected. This mechanism ensures that passengers are securely held in their seats during accidents, thereby enhancing safety and reducing the risk of injury.
Automatically-locking retractors. The strap equipped with an automatically-locking retractor shall not unwind by more than 30 mm between locking positions of the retractor. After a rearward movement of the wearer the strap shall either remain in its initial position or return to that position automatically on subsequent forward movement of the wearer.
Automatically-locking retractors. 6.7.3.1.1. The strap equipped with an automatically-locking retractor shall not unwind by more than 30 mm between locking positions of the retractor. After a rearward movement of the wearer the strap shall either remain in its initial position or return to that position automatically on subsequent forward movement of the wearer.
6.7.3.1.2. If the retractor is part of a lap strap, the retracting force of the strap shall be not less than 7 N as measured in the free length between the dummy and the retractor as prescribed in paragraph 7.2.4.1. below. If the retractor is part of a chest restraint, the retracting force of the strap shall be not less than 2 N or more than 7 N as similarly measured. If the strap passes through a guide or pulley, the retracting force shall be measured in the free length between the dummy and the guide or pulley. If the assembly incorporates a device, manually or automatically operated, that prevents the strap from being completely retracted, that device shall not be in operation when these measurements are effected.
6.7.3.1.3. The strap shall be repeatedly withdrawn from the retractor and allowed to retract, in the conditions prescribed in paragraph 7.2.4.2. below, until 5,000 cycles have been completed. The retractor shall then be subjected to the temperature test operation requirements given in paragraph 7.2.7.1. and corrosion test described in paragraph 7.1.1. below and the dust-resistance test described in paragraph 7.2.4.5. ▇▇▇▇▇.▇▇ shall then satisfactorily complete a further 5,000 cycles of withdrawal and retraction. After the above tests the retractor shall continue to operate correctly and to meet the requirements of paragraphs 6.7.3.1.1. and 6.7.3.1.2. above.
Automatically-locking retractors. The strap of a safety-belt assembly equipped with an automatically locking retractor shall not move more than 30 mm between locking positions of the retractor.
