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： 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 web sensor with an inertia member, a locking pawl and a lock cup. The inertia member is eccentrically pivotally mounted to the lock cup. The locking pawl is integrally formed with the inertia member. The lock cup has a set of radially inwardly pointing teeth for engaging with the locking pawl. The shape and profile of the locking pawl complements the shape of the teeth. The web sensor aids in resisting jamming of the seat belt retractor.

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： 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 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.

摘要： A calibration spring tension adjuster for a seat belt tension sensor has a calibration spring, and a holder. The fixed part and the movable part are adjacent to each other and comprise mutually facing stepped helical faces arranged so that the movable part can be rotated relative to the fixed part causing the steps to slide over each other causing a gap between the stepped faces to increase and compressing the spring. The steps can be arranged so that movement of the movable part in one direction is resisted. The holder is arranged to attach to the fixed part and the spring is held between an abutment face of the holder and a non-stepped face of the movable part.

摘要： A webbing sensor for a vehicle safety restraint retractor. The sensor comprises an inertial member, mounted for rotation coaxially with a retractor spool, a pawl for engaging the spool and locking it against rotation under emergency conditions, and a calibration spring biasing the inertial disc so that it tends to rotate with the spool unless there is a sudden acceleration or deceleration of a value such as to overcome the resilience of the spring. The spring is connected to the spool via the pawl so that relative rotation between the disc and the spool results in movement of both ends of the spring, preferably by approximately the same distance. Throughout the locking procedure, the spring force remains substantially constant and thus the bias torque on the inertia disc remains substantially constant, and the locking performance of the sensor is improved.
