ABSTRACT:
A passive seat belt system for a vehicle includes a restraint belt, a flexible transfer tape driven by a drive device in response to opening or closing of the vehicle door, and a belt transfer guide connected to the belt and connected to one end of the transfer tape, the guide being movable along a guide rail between restraint and release locations in the vehicle in which it holds the belt in occupant-restraining and occupant-releasing positions, respectively. The drive device comprises a flexible drive tape and a first drum having one end of the drive tape and the other end of the transfer tape attached to the outer periphery thereof whereby upon rotation of the drive in one direction both tapes are wound onto the first drum in interleaved relation and upon rotation in the other direction are unwound from the drum. A second drum is disposed adjacent the path taken by the transfer tape as it leads away from the first drum and has the other end of the drive tape attached to the outer periphery thereof whereby the drive tape is wound onto the second drum upon rotation thereof in one direction and is unwound upon rotation in the other direction. A drive mechanism selectively rotates the first and second drums in their respective tape-winding directions.
