摘要： A seat belt retractor for a vehicle safety restraint has a spool rotatably mounted in a frame. A ratchet wheel is rotatably mounted to rotate with the spool. A control member is mounted in the frame. A locking pawl is pivotally mounted in the frame to pivot into engagement with the ratchet wheel. A sensor is responsive to the spool. Upon activation of the sensor, a cam surface and a cam follower couple the locking pawl to the control member. The cam surface has a discontinuity arranged so that the cam follower loses contact with the cam at high speeds but stays in contact with the cam surface at low speeds. Preferably, the discontinuity is a raised portion providing a first ramp in one direction in one portion on one side of the discontinuity of the cam surface and a second ramp in a different direction in a second portion of the cam surface on the other side of the discontinuity.

摘要： A seat belt retractor has a webbing spool fixed to a ratchet wheel having a plurality of teeth spaced about its circumference. A locking pawl has a plurality of teeth with a pitch less than the pitch of the teeth on the ratchet wheel. The pawl is arranged to pivot into engagement with the ratchet wheel, on activation of a crash sensor. Preferably there are two locking pawls and two toothed ratchet wheels. The two locking pawls may each have the same number of teeth or alternatively one may have an extra tooth which serves as a sensor tooth, engaging first with the spool ratchet wheel and phasing engagement of the other teeth as the load increases.

摘要： A U-shaped frame for a seat belt retractor has two spaced arms made from a material of a predetermined thickness and having a cutout in the material of each arm for receiving a lockbar. Each cutout has an edge comprising a land portion for supporting the lockbar, which land portion is of a reduced thickness compared to the thickness of the material of the arms, to present a reduced surface area to the lockbar. The frame may be of pressed steel and the lockbar of die-cast non-ferrous material.

摘要： Two parts of a seat belt retractor spool sub-assembly are fixed together in an arrangement with plastically deformable formations on a first ratchet wheel and one end of a spool and corresponding deforming formations on a second ratchet wheel and said one end of the spool. A spool for a seat belt retractor is assembled with a ratchet wheel by: mounting a retractor frame on an assembly jig which has a spring loaded stop; mounting a spool in the frame by aligning the spool axis with the spring loaded stop; and pushing a ratchet wheel onto the end of the spool opposite to that contacting the stop until the ratchet wheel abuts the frame.

摘要： A lockbar for a seatbelt retractor has an elongate joining member and two end pieces joined to the joining member at opposite ends therefore. The end pieces are made of a higher strength material than the joining member. The joining member may be made by extrusion and may be tubular or may be formed as a hollow member. The end pieces may be produced as forgings, die casting or plastic injection moldings or by other suitable methods. They can be produced from different materials and to different designs to suit the specification of the seatbelt retractor. Hence a single basic seatbelt retractor design can be employed for a variety of strength requirements by selecting appropriate end pieces and an appropriate joining member.
摘要翻译：用于安全带卷收器的锁定杆具有细长的接合构件，并且因此在相对端处接合到接合构件的两个端部件。端片由比接合部件更高强度的材料制成。接合构件可以通过挤出制造，并且可以是管状的或者可以形成为中空构件。端部件可以用锻件，压铸件或塑料注塑件或其他合适的方法制造。它们可以由不同的材料和不同的设计生产，以适应安全带卷收器的规格。因此，通过选择适当的端部件和适当的接合构件，可以采用单个基本的安全带卷收器设计，用于各种强度要求。

摘要： A seat belt retractor has a spool having seat belt webbing wound thereon mounted for rotation in a frame. A toothed ratchet wheel is connected to the spool and rotates therewith. The retractor has a crash sensor. A locking pawl is arranged to be pivotable from a first position in which it is spaced from the ratchet wheel to a second position in which it engages with the ratchet wheel to lock the spool against rotation, in response to activation of the crash sensor. A pretensioner is responsive to the crash sensor to rapidly rewind webbing onto the spool. A venting arrangement for the pretensioner includes a chamber having an inside side wall and an inside wall. A vent hole is formed in the side of the chamber with a seal for the vent hole. An axially slidable member is mounted in the chamber and biased away from one end of the chamber. The slidable member is connected to the locking pawl, so that it slides in the chamber when the locking pawl pivots. Seals are arranged between the slidable member and the inside wall of the chamber during normal operation of the retractor, and when the locking pawl is in the first position to lie one on each side of the vent hole and to lie both on the same side of the vent hole when the locking pawl is in the second position.

摘要： A web clamping retractor comprising: a stationary frame (12) and a reel assembly (14), the reel assembly includes a mounting member (22) that is slidingly mounted to the frame via a U-shaped needle member (150). An upper leg (154) of the U-shaped needle member functions as an activation bar to move a clamping wedge (49a) into clamping engagement about a seat belt (19) after a spool or reel member has been pre-blocked. The lower leg (18) of the U-shaped needle member serves as a shaft about which the reel rotates.

摘要： A seat belt retractor has a spool on which seat belt webbing is wound, arranged for rotation about its longitudinal axis, for payout and winding in of seat belt webbing. A torsion bar is coaxial with the spool and has one end fixed to the spool. A ratchet is fixed to the other end of the torsion bar and a toothed wheel is fixed to the spool to rotate with the spool. A pivoting lock bar extends across the length of the spool, having at least one pawl fixed at each end, to engage with the toothed wheel and with the ratchet respectively. The pawl on the spool side is arranged to be weaker than the other pawl so as to shear under a predetermined force to allow the spool to rotate and the torsion bar to twist.
