SAFETY BELT SYSTEM WITH PRE-TENSIONING DEVICE FOR SECONDARY COLLISION

摘要

The invention concerns an adapted safety belt system in view of a secondary collision, comprising a tensioning roller with a force-limiting system whereof the triggering in case of collision is accompanied by the limited release of the strap from the blocked roller. To this end, the roller (9, 30) is associated with a pre-tensioning device (17, 33) actuated after the primary collision and eliminating the slack of the strap caused by the force-limiting system (13) subsequent to the primary collision.
