PCT No. PCT/SE85/00016 Sec. 371 Date Oct. 9, 1985 Sec. 102(e) Date Oct. 9, 1985 PCT Filed Jan. 17, 1985 PCT Pub. No. WO85/03262 PCT Pub. Date Aug. 1, 1985.A locking device for a band in a safety belt of a passive vehicle safety belt system comprises at least one fastening means (10) for the band (11) and a lock casing (15) into which the fastening means can be inserted and retained. The fastening means is adapted to be moved along a guide rail (13) by a traction means (16), controlled by an electric motor, and is adapted to be released from the traction means, when it engages with the lock casing, so that the traction means and the motor are not exposed to shock loads, when the fastening means engages with the lock casing. The traction means can continue its movement, when the power supply to the motor has been interrupted, so that the kinetic energy accumulated in the motor and the traction means can decay gradually. A slider (19) is attached to the traction means (16), and the fastening means (10) is releasably attached to the slider and is retained to the slider by means of pins (25.31) and a pawl (36). The pawl is adapted to be released from the slider, when the fastening means is moved into the lock casing. |
