摘要： A seat belt retractor comprises a rotatable spool on which seat belt webbing is wound. The spool is rotatable in a webbing withdrawal direction and an opposite webbing retraction direction. The seat belt retractor also comprises a pretensioner actuatable to rotate the spool in the webbing retraction direction and a load-limiting system to limit a load applied to a vehicle occupant by the seat belt webbing. The load-limiting system includes a torsion bar mounted such that the torsion bar is twisted when a load in excess of a predetermined load is applied to the spool in the webbing withdrawal direction by the seat belt webbing. The bad-limiting system also includes a stop assembly actuatable to limit rotation of the spool in the webbing withdrawal direction to a predetermined number of rotations while the torsion bar is being twisted. The stop assembly is actuated upon actuation of the pretensioner.

摘要： A seatbelt retractor is provided that can be formed in a smaller size yet properly operated, and capable of smoothly providing seatbelt tension, and a seatbelt assembly including such a seatbelt retractor. The seatbelt retractor includes a frame, a seatbelt, a spool that takes up the seatbelt, the spool being rotatably supported by the frame, a lock mechanism that allows the spool to rotate in a non-activated state and restricts, upon being activated, the spool from rotating in the seatbelt withdrawal direction, and an energy absorption mechanism that limits the load applied to the seatbelt to thereby absorb and alleviate energy of the occupant, and the energy absorption mechanism includes a first torsion bar concentrically enclosed in the spool with one end portion retained by the spool and the other end portion disposed to be locked by the lock mechanism, and disposed to be rotated by torsional force, a second torsion bar eccentrically enclosed in the spool with one end portion 24a disposed to be locked by the lock mechanism, and disposed to be rotated by torsional force, and a moving member that rotates interlocked with the spool, and moves between the first position for retaining the other end portion of the second torsion bar and the second position spaced from the other end portion of the second torsion bar.

摘要： A webbing take-up device is obtained in which the number of rotations of a spool from the start of deformation of a first energy absorption member until the start of deformation of a second energy absorption member can exceed one rotation. In a webbing take-up device, a restricting tab is provided at an open side of the engagement recess portion. Although the leading end of the stopper pawl and the engagement recess portion face each other in the first rotation of the lock ring, a leading end of a stopper pawl is thereby unable to enter inside the engagement recess portion. The restricting tab is restricted from rotating when the leading end of the stopper pawl abuts an abutting portion of the restricting tab. When the lock ring accordingly rotates in a pull-out direction, the restricting tab moves relative to the open side of the engagement recess portion. When the leading end of the stopper pawl and the engagement recess portion face each other in this state, the leading end of the stopper pawl is thereby able to enter the engagement recess portion.
摘要翻译：得到一种卷绕卷取装置，其中卷轴从第一能量吸收构件的变形开始直到第二能量吸收构件变形开始的转数可以超过一个旋转。在织带卷取装置中，在接合凹部的开口侧设置限制片。尽管止动爪和接合凹部的前端在锁定环的第一旋转中彼此面对，但止动爪的前端由此不能进入接合凹部内部。当止动爪的前端抵靠限制翼片的邻接部分时，限制翼片被限制旋转。当锁定环相应地沿拉出方向旋转时，限制片相对于接合凹部的开口侧移动。在该状态下，当止动爪和接合凹部的前端彼此面对时，止动爪的前端能够进入接合凹部。

摘要： A vehicle seat belt retractor with a belt shaft (10) and a coupled profile head lockable to a housing. A force-limiting device has at least two elements (11, 12) between profile head and belt shaft (10). Free ends (15, 16) of the force-limiting elements (11, 12) are coupled to each other by a connecting tube (13) via a coupling element (18). The coupling element (18) has a hook-shaped spring element with a locking hook (19) which slides over the connecting tube (13) when the belt shaft (10) rotates and engages in a locking groove (20) to couple the connecting tube (13) to the belt shaft (10). At a preset angle of rotation of the belt shaft (10) is reached, the bridging device releases the coupling element (18) for the locking hook (19) to latch into the connecting tube locking groove (20).

摘要： A belt retractor for a vehicle seat belt includes a rotatably supported belt reel (12) from which webbing can be unwound, a force limiting means which in a force limiting phase permits controlled webbing extension in the webbing extension direction when the belt reel (12) is blocked and a particular force threshold is exceeded, and a change-over device for carrying out a change-over operation before and/or during the force limiting phase in which it is changed from a first force level to a second force level. The change-over device includes a control means adapted to trigger or inhibit the change-over operation at least in response to the recognition of an installed child safety seat (34).

摘要： A seat belt retractor including a belt shaft rotatably supported in a frame and two force-limiting devices acting in parallel. The first and the second part of the belt shaft axially overlap forming an annular space. The second force-limiting device is a band element abutting a radial outer wall of the annular space with a first section, and on the radial inner wall with a second section and is deflected in a deflection fitting between the first and the second sections (20, 21, 29, 30). During relative movement between the first and second parts, the band element can be unwound or wound up from the outer wall onto the inner wall or vice versa in an energy-dissipating manner.

摘要： When a gas generating member of a pretensioner mechanism is activated in case of vehicle collision, a piston inside a pipe cylinder is moved from normal state and a pinion gear body is rotated. Thus, the teeth of the pinion gear portion come in contact with a push block and pushes it in outward direction in conjunction with a force of a block urging spring, whereby a rotating lever is rotated by the push block and the lower end portion of the rotating lever gets disengaged from the tip end portion of a gear-side arm. As a result, the gear-side arm is rotated by an urging spring in outer direction and rotates a mechanical arm through a coupling shaft to make the pawl engage a ratchet gear of a take-up drum unit.
