摘要： A torsion bar (23) is mounted inside a take-up drum (6) with its one end fixed thereto for disabling its relative rotation with respect to the take-up drum. A slit (220A) is formed in parallel to rotational axis of the take-up drum and allows one end of the webbing (3) to pass through. At one end of the webbing, there is provided a slip-off prevention member (220). Length consisting of the slip-off prevention member's diameter and thickness of the webbing surrounding the slip-off prevention member is longer than distance between outer-diameter-side surface of the slit at the take-up drum and outer diameter surface of the torsion bar inside the take-up drum so as to prevent escape of the slip-off prevention member therefrom. The slip-off prevention member's load to depress the take-up drum in fully-pulled-out state of webbing is received by both the torsion bar and the take-up drum, which can improve webbing-pull-out intensity.

摘要： A seat belt system (10) includes a lap belt (60) including a first portion (74) and a second portion (85). A retractor (76) includes a spool (96) rotatable about an axis (160). The first and second lap belt portions (74, 85) are secured to the spool (96). The spool (96) is biased to rotate in a first rotational direction to wind the first and second portions (74, 85) onto the spool. The first and second portions (74, 85) when tensioned urge the spool (96) to rotate in a second rotational direction opposite said first rotational direction to unwind the first and second portions from the spool. A locking mechanism (170) is actuatable to lock the spool (96) against rotation in the second rotational direction. First and second web grabbing devices (180, 182) are actuatable to clamp onto the first and second portions (74, 85) when the locking mechanism (170) is in the locked condition.

摘要： A spool for a seat belt retractor has a cylindrical member with a cylindrical central portion and two end plates at opposite axial ends of the cylindrical portion. There is a channel formed in the cylindrical central portion with an outer and an inner wall and defining a path for guiding seat belt webbing. The path circumscribes the spool axis substantially over the length of the central portion of the spool in a generally smooth curve. The path has a spool entry and a spool exit portion and an acute angle subtended at the spool axis by the entry portion of the path and the exit portion of the path is approximately 90°. The spool may be hollow with a torsion bar forming the inner wall of the channel.

摘要： A retractor for a vehicle safety belt is provided, comprising a housing, a load bearing ratchet pawl supported in the housing, and a belt drum rotatably mounted in the housing. The belt drum is provided with ratchet disks at its axial ends. The ratchet disks are coaxial with the belt drum and are provided with a ratchet toothing at its outer circumference, into which the ratchet pawl can be engaged for locking the belt drum in the direction of pay-off of belt webbing coiled on the belt drum. The belt drum is further provided with energy take-up means arranged in the power transmission path between the belt drum and the ratchet disks. This energy take-up means are adapted to allow rotation of the belt drum in relation to the ratchet disks in the pay-off direction under heavy strain.

摘要： A retractor for a seat belt includes a retractor base, a bobbin fixed to a winding shaft rotatably supported to the retractor base for winding a webbing, and a webbing guide having a first positioning portion located on the side of the bobbin and a second positioning portion located on the side of the upper end of the retractor base. The webbing guide is fixed to the retractor base for regulating a webbing moving path so that the webbing wound around the bobbin is drawn out from a prescribed position on said retractor base. The first and second positioning portions each has a protrusion portion provided with a plurality of protrusions abutting on the surface of said webbing and the surface of each protrusion abutting on said webbing forms a smooth bending face. The retractor provides a small change in the contact resistance between the webbing and the webbing guide positioning the webbing in a retractor base and can maintain smoothness of the draw-out and winding operations of the webbing, so that it is effective to improve the reliability of the draw-out and winding operations in the retractor and also general versatility of the retractor.

摘要： According to the invention, a belt retractor comprises a frame and a belt reel provided with a longitudinal axis and a peripheral surface. The belt reel is rotatably mounted in the frame and is provided with an interior cavity which is coaxial with the longitudinal axis. The belt reel is further provided with a slot having a minimum width and extending in parallelism to the longitudinal axis. The slot is open towards the peripheral surface of the belt reel and towards the interior cavity. The belt reel further comprises a rod extending coaxially through the interior cavity with a radial play. The belt retractor further comprises a belt webbing connected to the belt reel with one end section having an end. The end section extends through the slot, around the rod and finally through the slot out of the interior cavity. The end of the end section is provided with a thickened part having a width which, as measured in a direction transverse to the longitudinal axis, is larger than the minimum width of the slot.

摘要： A webbing retractor is provided with a lock mechanism. The webbing retractor further comprises a bobbin, a webbing-holding member and a webbing. The bobbin has a drum portion and a pair of flanges arranged on opposite ends of the drum. The flanges define grooves formed in a mutually-opposing relationship and angularly extending over a predetermined length in a webbing-releasing direction as a first direction of rotation. The webbing-holding member extends between the grooves. The webbing is secured at one end thereof in the bobbin, wound back about the webbing-holding member at a first portion thereof apart from the one end thereof toward an opposite end thereof, and then wound in layers around the drum portion in the first direction of rotation at a second portion thereof closer to the opposite end than the first portion.
