ABSTRACT:
A belt carriage is movable along a vehicle body mounted track to move an occupant restraint belt between an occupant restraint position and a stowed position permitting occupant ingress and egress. A plastic drive tape is attached to the carriage and has perforations which mesh with a toothed tape drive gear for driving the drive tape and carriage back and forth along the track. An electric motor and a speed reduction gear unit are connected to the tape drive gear by a clutch which couples with the drive gear only when the electric motor is energized so that whenever the electric motor is not energized the occupant may grip the belt carriage and manually move the belt carriage and the drive tape to move the restraint belt between the occupant restraint and stowed positions independently of the motor. The clutch is preferably a centrifugal clutch in which clutch pawls are thrown outwardly by centrifugal force to engage with the tape drive gear when the motor is energized.
