Coupling for joining a drive wire to a belt transfer member

Claim 1

In a passive vehicle occupant restraint belt system having a restraint belt, a guide rail, a belt transfer member coupled to a portion of the belt and movable along the guide rail, and drive means including a drive wire for moving the transfer member along the guide rail between occupant-restraining and occupant-releasing positions in response to closing and opening of the vehicle door, a coupling assembly joining the drive wire to the transfer member and comprising a post affixed to the transfer member and including at least one retaining shoulder facing the transfer member, a resilient coupling member having a multiplicity of radially arranged resilient tangs, the free ends of which define a hole that is normally slightly smaller than the post cross section, the coupling member being receivable on the post with the free ends of the tangs resiliently engaging the post and stopped by the shoulder from sliding off the end of the post, and a connector terminal affixed to the end of the drive wire, the terminal having a hole receiving the post and a pair of side flanges, each of which includes a locking shoulder that faces away from the free end of the terminal, and the coupling member further including a pair of generally L-shaped side retainer flanges that engage the side flanges of the terminal and a pair of lugs that engage the respective locking shoulders of the terminal, whereby the coupling member is adapted to be pre-assembled with the terminal on the drive wire and the coupling assembly is adapted to be finally assembled to connect the drive wire to the transfer member by pushing the pre-assembled coupling member and terminal onto the post.
