    Abstract: In accordance with the present invention, there is provided a noise suppression mechanism for a seat belt retractor used in a vehicle. The preferred retractor includes a reel journaled on a reel shaft and having attached a ratchet wheel with ratchet teeth. The ratchet teeth may be engaged by a pivotally frame-mounted locking pawl. The pawl may pivot between an inoperative position in which the pawl is spaced from the ratchet wheel and an operative position in which an inertial device urges the pawl into engagement with the ratchet wheel to prevent protraction of the belt. The preferred noise suppression mechanism may include an interlocking disc being mounted on reel shaft for rotation with the ratchet wheel for rotating between an actuated position for immobilizing the locking pawl against rattling and a neutral position allowing the locking pawl to pivot freely. The disc may have a blockout cam having a curved engaging surface for engaging a pawl being spaced at different positions with respect to the ratchet wheel. A spring may be employed for uniformally biasing the disc into engagement with the ratchet wheel. The disc has predetermined rotation for preventing interference with the other retractor components and for ensuring effective application of the blockout cam for engaging the pawl for immobilizing the pawl.

    Abstract: The present invention provides an intentionally set or overt comfort system to be employed in a vehicle seat belt retractor for rewinding a seat belt. The system requires an overt activation by the occupant through a predetermined sequence of deliberate belt manipulations for activating the intentional set comfort system and subsequently actuating the tension-relieving mode. The preferred intentional set comfort system comprises primarily two major components which include a belt sensing activation mechanism and a tension-relieving mechanism. The belt sensing mechanism senses a deliberate protraction of the belt beyond a distance of normal occupant use for shifting the tension-relieving mechanism to an activated state. In response to the belt sensing activation mechanism, an actuator arm shifts the tension-relieving mechanism to its activated state. The tension-relieving mechanism includes a disc, having a plurality of grooves, mounted for rotation with the reel shaft and a spring biased blocking finger mounted for pivotal movement that is initially spaced from the disc. Upon activation of the tension-relieving mechanism, the finger is moved into the grooves and cooperates with the grooves to initially remove belt slack. In order to actuate the tension-relieving mode, the occupant, subsequent to removal of the belt slack, makes a slight protraction of the belt to cause the tension-relieving mode. However, belt protraction beyond the predetermined distance will result in automatic disengagement of the belt from the tension-relieving state and thereby causing reversion to the tension mode under the retraction spring force.

    Abstract: A free-falling, self-locking adjustable tip assembly is provided for a safety belt apparatus, which has a seat belt retractor at one belt end and for rewinding the belt and pulling one belt portion into a generally vertical position at belt release. A tip-assembly engagement means contacts the belt and acts on a slide with a first rib on the slide movable across the top of a tongue plate to wedge the belt between a pair of ribs on an insert carried by the tongue plate. The first rib is on a metal slide means and is located above the tongue plate, as are the pair of ribs on the insert. The locking of belt prevents transfer of the belt from the shoulder portion to lap portion is at a location above the tongue plate. When the tip assembly is unbuckled, the grip is released and the tip assembly free falls along the belt.
