Abstract

The locking means for the drive member of a passive safety-belt system includes a pivotally mounted ratchet hook which secures the drive member in its end position corresponding to the belt fastening position. The ratchet hook is arranged on the side of the drive member to which the tensile force occurring at the drive member is directed under accident load. The nose of the ratchet hook dips into a recess at the upper edge of the drive member. Even after high accident stress due to a head-on collision, in which deformation of the loaded parts occurs, the ratchet hook remains reliably in engagement with the drive member.
