The invention relates to a seat belt retractor (10), comprising a frame (12), a sensor (16) for vehicle-sensitive blocking that having a sensor lever (22), comprising a belt reel (14) and a cam follower (30) that is coupled to the belt reel (14) by way of a coupling (32), which is adjustable between a starting position, in which the sensor lever (22) is blocked, and a pull-out position, in which the sensor lever (22) is released. The coupling (32) is a wrap spring coupling having a drive element (34) that is coupled to the belt reel (14) and an output element (40) connected to the cam follower (30), wherein the drive element (34) and the output element (40) each have an annular outer friction surface (38, 44) and are arranged concentrically to one another. A spiral spring (46) is provided, which bears against the friction surfaces (38, 44) and which couples the output element (40) to the drive element (34).

[Object] To cancel both a function of a vehicle sensor and a function of a webbing sensor at a predetermined condition while having a simple structure and a fewer number of parts. [Solution] When fully retracting a seat belt 4, a cam follower 22b abuts against a first cam portion 20a; accordingly, an actuator holding portion 23b urges an actuator 13b in a non-operable position and a function of a vehicle sensor 13 is canceled. When a large load is applied to the actuator holding portion 23b while in the above canceled state, the load is supported by the first cam portion 20a; accordingly, first and second second levers 22 and 23 do not pivot and cancellation of the function of the vehicle sensor 13 is prevented from being canceled. Furthermore, when a lock claw 22c is separated from a ratchet tooth 17b, a ring gear 17 becomes rotatable and a function of a webbing sensor 12 is canceled.

An apparatus and method are provided for hermetically sealing locking components of a retractor wherein the retractor has a spool shaft extending therefrom. An open-ended housing has a base and defines an opening through the base into an interior of the housing. The base of the housing is mounted to the retractor with the spool shaft accessible via the opening. The locking components are arranged within the housing. A sealing member is positioned about the opening to form a hermetic seal between the spool shaft and the opening. A cover is hermetically attached to the open end of the housing.

An acceleration sensor assembly for a restraint retractor of a seat restraint system in a vehicle includes an acceleration sprocket operatively connected to the restraint retractor. The acceleration sensor assembly also includes an acceleration pawl cooperating with the acceleration sprocket to operatively cause lock up of the restraint retractor. The acceleration sensor assembly includes an inertia member cooperating with the acceleration pawl to move the acceleration pawl when an acceleration force is present and a gimbal to support the inertia member. The acceleration sensor assembly further includes a non-contact damping mechanism cooperating with the gimbal to dampen movement of the gimbal until the acceleration force exceeds a predetermined value and the inertia member actuates the acceleration pawl to engage the acceleration sprocket to operatively cause lock up of the restraint retractor and prevent unwinding of a belt from the restraint retractor.
