A height adjuster for a vehicle safety restraint has a web guide ( 38 ) and a track ( 84 ) for the web guide. The web guide ( 38 ) is vertically moveable along the track ( 84 ). A lock ( 76 ) has a lock condition for preventing vertical movement of the web guide ( 38 ) along the track ( 84 ) and an unlocked condition for allowing vertical movement of the web guide ( 38 ) along the track ( 84 ). A release mechanism ( 50, 80 ) is operatively connectable to said lock ( 76 ). The release mechanism ( 50, 80 ) has a release position for placing the lock ( 76 ) in the unlocked condition and an unreleased position from maintaining the lock ( 76 ) in the lock condition. A lift mechanism ( 66 ) at least partially assists vertical movement of the web guide ( 38 ) along the track ( 84 ) and biases the release mechanism ( 50, 80 ) toward the unreleased position.
