Abstract: A passive restraint system includes a torso belt automatically securing a vehicle occupant by moving from a forward position along a track to a rearward position. A belt carrier carries one end of the torso belt along the track while the other end of the torso belt is retained on a belt retractor. Adjustment of the location of a vehicle seat during travel of the torso belt could cause inadvertent latching of the retractor latching mechanism which results in stalling of the belt carrier. The present invention inhibits torso belt movement whenever the seat is adjusted to prevent such latching. When the seat adjustment is completed, the torso belt movement is resumed.
