    摘要: An electromechanical seat belt retractor has a seat belt retractor assembly having a spool rotationally moveable about an axis of rotation for winding and unwinding a seat belt; a motor for selectively rotating the spool; a clutch including an over-clutch driven by the motor through one or more gears; the clutch being coaxially aligned with the axis of rotation of the spool and linearly spaced from the spool; and wherein upon a forward actuation of the motor a clutch plate of the clutch linearly moves to engage the spool coupling to the spool and thereafter rotating the spool about the axis to initiate a winding of the seat belt. After the clutch plate engages the spool a reversal of the motor linearly moves the clutch plate away from the spool disengaging the spool. Preferably the clutch means is a Bendix type clutch assembly. In a preferred embodiment, the clutch plate first engages an over-clutch is fixed in a locking engagement to the spool.

    摘要: A pretensioner for a motor vehicle belt restraint system mounted to a structure of the vehicle. The pretensioner is connected to a belt restraint component that is also connected to the belt restraint system. The pretensioner includes a conduit made of tubing and having first and second ends. At least a portion of the conduit defines an elongated piston bore with a piston slideably positioned therein. A cable is attached to the piston and extends through the conduit for connection to the belt restraint component. A micro-gas generator is also located within the conduit and positioned generally opposite of the piston. Upon activation of the micro-gas generator, a gas is generated in the piston bore and drives the piston such that the piston exerts tension on the cable and thereby on the belt restrain component.

    摘要: A seat belt buckle (100) operable with a pretensioner (330) comprising: a frame (102) having a first latch opening (126a) therein, and opposing frame sides (108a,b), each side including a latch plate slot (110) arranged generally perpendicular to the direction of movement of a tongue into the buckle and pivoted weight mechanism (112, 200, 220). The buckle additionally includes a latch plate (180), having portions (186) movable within the latch plate slots between a locked position in engagement with an opening within the tongue and with the first latch opening (126a), the latch plate moveable between a latched position within the latch opening (126a) in the frame and within the latch opening (173) of the tongue to an unlatched position out of the latch openings. The weight (200) as it pivots generates a force upon the latch plate during operation of the pretensioner tending to keep the latch plate in the first opening and a button (250) operatively received upon the frame having ramp means (260) for lifting the latch plate to its unlatched position.

    摘要: A seat belt retractor assembly has a seat belt retractor for generating a retraction force to rewind a seat belt on a reel. A coupling device selectively couples and decouples the retractor from the reel. A tensioning device generates a tensioning force in the seat belt when in an activated state. The coupling device decouples the retractor from the reel when the tensioning device is activated.

    摘要: A seat belt retractor for providing extraction and retraction of seat belt webbing incorporating a belt tension sensing mechanism. The sensing mechanism includes a webbing guide which is moveable between positions and is biased toward a low tension position by a restoring spring force. The belt webbing is routed to deflected path through the web guide. Increasing tension on the webbing will cause the web guide to change its position as the webbing path straightens. The position of the web guide is detected through an electrical switch to provide a measure of webbing tension.
