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: A safety belt retractor in which the reel is supported on a movable frame which cooperates with a braking mechanism such that when the reel locks, subsequent belt tension displaces the movable frame into camming engagement with a pivoting braking mechanism to shift a brake shoe into direct contact with the belt web. The brake shoe is supported on the braking mechanism for movement relative thereto. The brake shoe and its mounting portions preferably have complementary interfitting bearing surfaces which share a common axis of curvature, with the bearing surface on the brake shoe being convex, and the complementary surface on the cam being concave.

Abstract: Seat belt retraction apparatus including a seat belt retractor mechanism including a reel about which the strap of a seat belt is wound and which carries ratchet wheels. The retractor mechanism is adapted to take up and let out the strap and is provided with an inertia weight locking mechanism to lock the reel against paying out the strap. The retractor mechanism is for mounting in a vehical door and the inertia locking mechanism will not lock the reel at a lower force level such as 0.7G, when the door is swung. However, the retractor mechanism will operate at this lower 0.7G level to lock the reel against belt pay out when the vehicle chassis decelerates at a 0.7G level as at the time of an accident. Preferably, an inertia operable switch is located on the vehicle chassis but at a location not effected by the swinging of the vehicle door. A magnetic force holds the inertia weight locking mechanism against locking as the door is swung at the lower force level of 0.7G and in a range up to 2.4G at which time the magnetic force is overcome. At the time of an accident at the lower force level of 0.7G, the inertia switch operates an electromagnetic device in opposite to the permanent magnetic field so that inertia weight locking mechanism may lock the reel at this lower force level.

Abstract: A dual spring seat-belt retractor system with a tension-ease system operable to provide one of two springs continuously maintaining a retractive force on the belt to maintain the belt against the wearer in the tension-ease mode, which tension-ease system is automatically initiated at the cessation of belt protraction with a slight retraction to engage latch means that renders one of the springs ineffective to provide a reduced belt tension. A lost motion connection between the belt reel and the latch means permits limited belt movement by the user while maintaining the reduced tension until a predetermined retraction occurs.

Abstract: An inertia retractor may be provided with an automatic locking mode by the addition of an assembly mounted as an attachment to sidewall of the inertia retractor. The assembly allows the retractor to be used as an inertia retractor until the belt is pulled to a predetermined extent whereupon a belt coil sensor senses this predetermined belt extraction and operates an actuator to shift a pawl into locking engagement with the ratchet wheels and thereby into the automatic locking mode. When the belt rewinds, the belt coil sensor deactivates the ALR mechanism by latching the pawl actuator thereby allowing an inertia member to again operate the pawl to the locking position upon a deceleration of sufficient magnitude.

Abstract: A safety belt retractor is provided with a frame that rotatably supports a reel carrying a rolled safety belt and with a pair of ratchet wheels on the opposite ends of the reel. A locking bar is pivotally mounted with respect to the frame for travel into engagement with the ratchet wheels to prevent protraction of the safety belt from the reel. An inertia-sensitive device is mounted on the frame and is movable with respect thereto to actuate the locking bar for engagement with the ratchet wheels. A block-out device for preventing the locking bar from engaging the ratchet wheels when the vehicle door is opened includes a solenoid with a plunger movable in response to the opening of the car door. A rock lever is pivotally mounted with respect to the frame and operatively connected to the plunger. A block-out member is pivotally mounted with respect to the stationary shaft and have a first end operatively connected to the lever, the second end being free and movable into a blocking position to prevent engagement of the locking bar with the ratchet wheels. The block-out device is configured so that when the lever pivots in response to the opening of the car door, the moment exerted on the lever by the solenoid plunger is in the same direction as any moment that would be exerted on the lever due to the locking bar engaging the block-out member.

Abstract: In a dual spool seat belt retractor system where one retractor reels in a shoulder belt and another retractor reels in a lap belt and at least one of the retractors, e.g., the shoulder belt retractor, has an associated tension relieving mechanism which relieves the winding spring tension from the belt worn by the occupant, a device associated with the tension relieving mechanism for releasing the mechanism from its tension relieving mode is actuated by a cable extending between the two retractors. One end of the cable is connected to the release device and the other end is connected to the lap belt retractor in a manner that is senses full lap belt retraction. In a preferred embodiment, the cable is looped partially around the windings of the lap belt retractor so that as the diameter of the lap belt winding increases during lap belt retraction, the cable loop expands causing the other cable end to pull on the release device. The cable actuator is adaptable to a two retractor seat belt system irrespective of the relative orientations of the two retractors. A mechanism is also provided to allow the retractor to be mounted at several angles to the vertical, e.g., 45.degree. and still use the vertical displacement of an inertia member to lock the retractor.
