ABSTRACT:
A vehicle belt system includes a restraint belt having shoulder belt and lap belt ends mounted on the door and an anchor belt mounted inboard the occupant seat and connected to the restraint belt by a disconnect buckle. A storage retractor mounted on the door has the shoulder or lap belt end connected thereto. A spring biases the reel in the belt winding direction. A pawl and ratchet mechanism is operable by a reel driven cam to lock the reel in response to full unwinding of the belt from the reel so that the belt is normally held at the fully extended length appropriate for restraint of seated occupant. The retractor also includes a release device which unlocks the pawl and ratchet mechanism so that the restraint belt will be retracted and stored upon the spring wound reel when the disconnect buckle is released. The release device is preferably an electrical switch in the release buckle which controls an electromagnet for unlocking the pawl and ratchet mechanism or a manually operable push button mounted on the door for unlocking the pawl and ratchet mechanism.
