摘要： A seat belt retractor with a ball type pretensioner including a pipe in which the balls are retained. A front end portion of the pipe is securely retained so that reliable operation of the pretensioner is provided. The pipe does includes a cut-out that does not extend to the front-most end of a pipe. A guide block is fitted in the front-most end of the pipe. The pipe and the guide block are fixed to the plate together by a fastener. The portion where the guide block is fitted to the pipe can provide high rigidity and is thus hardly deformed in every directions. The fastener may be hardened or the material for the fastener may be selected to obtain sufficient strength.

摘要： To provide a pre-tensioner which can effectively use ignition pressure of a gas generator and can be constructed in a compact form as a whole and have lighter weight, a pre-tensioner 10 is mounted outside of a side wall 50 of the frame 2 by a base 41. A hexagonal head portion 4d of a reel 4 penetrates a base 41. Fixed to the outer periphery of the hexagonal head portion 4d is a pinion 23. The pinion 23 is provided with external teeth 24 uniformly formed around the periphery thereof. A ring gear 30 is disposed to surround the pinion 23. The ring gear 30 has internal teeth 31 engageable with the external teeth 24 of the pinion 23. The ring gear 30 has levers 32, 33 projecting outwardly, which are formed on the outer periphery of the ring gear 30 at predetermined interval. The lever 32 of the ring gear 30 is substantially in contact with the head ball 20-15 within the pipe 21.

摘要： A seat belt retractor of the invention is basically formed of a first reel, a second reel, a rope extending between the first reel and the second reel, and a spiral spring situated in the second reel as an urging force providing device. The first reel is connected coaxially to a rotational axis of a reel shaft for winding a webbing, and has a drum shape on which the rope fixed at one end to the first reel is wound. The second reel has a rotational shaft disposed parallel to and laterally spaced away from the first reel. The second reel includes a small diameter reel portion, a large diameter reel portion, and a transition portion connecting the small diameter reel portion and the large diameter reel portion. The rope attached to the first reel extends to the small diameter reel portion and the transition portion, and is wound around a groove of the large diameter reel portion. The seat belt retractor is improved in assembling the members, and an approximately constant force for withdrawing the webbing can be achieved even if a withdrawal amount of the webbing is increased.
摘要翻译：本发明的安全带卷收器基本上由第一卷轴，第二卷轴，在第一卷轴和第二卷轴之间延伸的绳索和位于第二卷轴中的螺旋弹簧作为推动力提供装置形成。第一卷轴与卷轴的旋转轴线同轴地连接，用于卷绕织带，并且具有卷绕在一端固定在第一卷轴上的绳索的滚筒形状。第二卷轴具有平行于第一卷轴并与第一卷轴横向间隔开的旋转轴。第二卷轴包括小直径卷轴部分，大直径卷轴部分和连接小直径卷轴部分和大直径卷轴部分的过渡部分。附接到第一卷轴的绳索延伸到小直径卷轴部分和过渡部分，并且卷绕在大直径卷轴部分的槽上。安装带卷收器在组装构件方面得到改进，即使织带的抽出量增加，也可以获得大致恒定的用于抽出织带的力。

摘要： A seat belt retractor which achieves stable performance of a pretensioner. The seat belt retractor includes a spool for winding up a belt thereon. The spool has a shaft portion, a spool gear, and a spring-biased shaft projection which are disposed to project from a face of the spool. A spool bearing (or ring-like collar) is fitted around the shaft portion of the spool. The spool bearing is made of a material having high hardness and high rigidity such as SUS or SC. By this spool bearing, the spool is prevented from being directly subjected to load, like a bearing.
