摘要： In a webbing take-up device, in a case in which the acceleration with which a webbing is pulled out from a spool, which is based on the radius of the webbing taken up on the spool and the angular acceleration of rotation of the spool in the pull-out direction that are detected by an angle-of-rotation sensor, is equal to or greater than a predetermined acceleration, a lock mechanism locks the rotation of the spool in the pull-out direction. For this reason, the rotation of the spool can be locked on based on the acceleration with which the webbing is pulled out from the spool.

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 seat belt device includes a spindle (11) for retracting a seat belt (13), an electric actuator (55), a pre-tensioner (14) and a power transmission mechanism (20), wherein the power transmission mechanism (20) can reversibly switch the connection and disconnection between the electric actuator (55) and the spindle (11) before the pre-tensioner (14) is activated, while when the pre-tensioner (14) is activated. The power transmission mechanism (20) non-reversibly interrupts the connection between the electric actuator (55) and the spindle (11) via an elastic piece (60) when a torque difference between an actuator-side gear (80) and a spindle-side gear (82) becomes larger than a predetermined value.

摘要： A webbing take-up device includes a spool and a spiral spring that biases the spool in a take-up direction and a motor provided with an output shaft. The webbing take-up device further includes a first clutch that transmits forward direction rotation of the output shaft to the spool, rotating the spool in the take-up direction. The webbing take-up device further includes a second clutch including: weights that are rotated by the output shaft and that open out under their own centrifugal force; a connection-disconnection mechanism that receives force from the weights opening out and connects so as to enable rotation of the output shaft to be transmitted to the spool; and projection portions serving as load limiting portions that limit the load imparted to the connection-disconnection mechanism so as not to become a specific value or greater.

摘要： The invention relates to a locking unit (4) for a seat belt retractor (1), which locking unit (4) is provided at one end of a seat belt spool (3) of the seat belt retractor (1), on which a seat belt (2) is retracted, so that when the seat belt (2) is quickly unrolled a locking arm (14) of a locking lever (13) is locked with an internal gearwheel (Z), as a result of which the seat belt spool (3) is locked, wherein the locking unit (4) has the following elements: the locking lever (13) with a center of rotation (D) arranged spaced apart from the center of the seat belt spool (3), an actuator arm (15) and the locking arm (14); a triggering unit having an inertia weight (17), a counter-pressure spring (18) and a transmission arm, which engages with the actuator arm (15), wherein the triggering unit is formed to rotate the locking lever (13) about the center of rotation (D) and to lock the locking arm (14) by means of the stationary internal gearwheel (Z) that is arranged about the locking lever (13) in the case of a fast acceleration of the unrolling of the safety belt (2), conditioned by the inertia force of the inertia weight (17) acting against the spring force of the counter-pressure spring (18), wherein a cover ring (19) is provided between the locking lever (13) and the internal gearwheel (Z), which cover ring (19) can be rotated into a covering position when the seat belt (2) is retracted, in which covering position the cover ring (19) at least partially covers the region between the locking arm (14) and the internal gearwheel (Z) in order to prevent locking, and which can be rotated into a release position when the seat belt (2) is unrolled, in which release position the cover ring (19) releases the region between the locking arm (14) and the internal gearwheel (Z) in order to permit locking.
