Abstract
Abstract A vehicle body includes a door movable between open and closed positions and mounting a door lock engageable with a striker on the body for holding the door in closed position. The lock is of the uncoupling type and includes inside and outside release handles connected to an operating lever which is selectively coupled to and uncoupled from the detent for the lock bolt. A restraint belt includes lap and shoulder belts which are moved between restrained and unrestrained positions with respect to an occupant seating position upon extension and retraction of an outboard belt relative to a belt retractor mounted on the door. The retractor includes a belt anchoring reel having ratchet end plates and a pawl which is normally spring biased into engagement with the end plates to block movement of the reel in a belt extending direction. A first release lever is mounted on the retractor and resiliently biased into engagement with a fixed stop to locate the lever in unactuated position. When the first lever is moved to actuated position, it engages a pawl extension to move the pawl into released position. A manually operable handle on the retractor is movable independently of the first release lever into engagement with the pawl extension to also move the pawl to released position. A blocking lever is mounted on the lock and is resiliently biased to blocking position. The blocking lever is moved to unblocking position by engagement with the striker when the bolt moves to latched position in engagement therewith. A second release lever is mounted on the lock for movement transversely of the path of movement of the blocking lever. A rod connects the first and second levers for simultaneous movement to thereby normally locate the second lever in unactuated position wherein it is engageable by the lock operating lever. When either release handle is operated and the lock operating lever is uncoupled from the detent, the lock operating lever moves the second release lever to actuated position transverse of the path of the blocking lever and likewise moves the first lever to actuated position to release the pawl. When the release handle is released, the first and second levers return to unactuated position. When the lock operating lever is coupled to the detent, movement thereof by a release lever releases the pawl and also releases the lock bolt from the striker. The initial opening movement of the door permits the blocking lever to move to blocking position in the path of the second release lever and block return movement thereof and of the first lever to unactuated position when the release handle is released. The pawl thus remains released while the door is open.
