摘要： A serrated portion is formed on an outer peripheral portion of a lock base body of a lock base of a webbing take-up device. Furthermore, a flange portion is formed on the outer peripheral portion of the lock base body. The flange portion is disposed on a vehicle front side with respect to the serrated portion. Triangular grooves of the serrated portion are closed by the flange portion. When the lock base becomes displaced in a vehicle rearward direction and the flange portion comes into abutting contact with a leg plate of a frame, further displacement of the lock base in the vehicle rearward direction is blocked. Due to this, engagement between the serrated portion and ratchet teeth of a ratchet hole in the leg plate can be maintained.

摘要： A belt tensioner for a belt retractor having a load limiter includes a pivoted pinion (14) coupled to a belt reel, a drive unit and a load transmission element (20) moved by the drive unit. The load transmission element (20) engages in the pinion (14) so as to rotate the pinion in a tensioning direction A. The load transmission element (20) is designed so that in the rotational position adopted by the pinion (14) after being rotated by the load transmission element (20) a part (20b) of the load transmission element (20) engages in the pinion (14). A method of tensioning a seat belt by means of a belt tensioner and subsequent load limitation by means of a load limiter includes moving a load transmission element (20) by a drive unit in a first direction so that the load transmission element (20) engages in a pinion (14) coupled to a belt reel (12). The rotating the pinion (14) is rotated by the moved load transmission element (20) in a tensioning direction A. When the rotation of the pinion (14) is completed it is ensured that a part (20b) of the load transmission element (20) engages in the pinion (14).

摘要： In a webbing take-up device, a FL lock pawl is actuated by rotation of a spool in a pull-out direction relative to a lock base, coupling the spool and a lock ring of an energy absorption mechanism together by the FL lock pawl. A reduction in number of times the FL lock pawl is actuated is thereby enabled in comparison to a case in which the FL lock pawl always actuates on actuation of a lock mechanism. The occurrence of wear or the like of ratchet teeth of the FL lock pawl is suppressed as a result. Accordingly, improvement of margin for durability of the FL lock pawl that actuates the energy absorption mechanism is enabled.

摘要： A retractor includes a spool configured to selectively wind and unwind the webbing, a lock base configured to operate in a free position and a locked position, a first energy absorbing member coupled to the spool and the lock base, and a second energy absorbing member coupled to the spool and the lock base. When the lock base is in the free position, the spool and lock base freely rotate together when a force is applied on the spool through the webbing. When the lock base is in the locked position and a force is applied on the spool through the webbing, rotation of the spool is permitted while rotation of the lock base is prevented, such that the first energy absorbing member absorbs a first energy and the second energy absorbing member is configured to absorb a second energy after a predetermined rotation of the spool.

摘要： A restraint system for a vehicle, includes a rotatable reel, a flexible tether, a first shaft and a conductor member. The flexible tether has a first end coupled to the reel and a second end. The tether is wound upon the rotatable reel and movable in both a winding direction and an unwinding direction. The first shaft is configured to be operably coupled to the rotatable reel, and includes a plurality of magnetic elements affixed thereto. The conductor member has a hollow interior. At least a portion of the first shaft and at least a portion of the plurality of magnetic elements are disposed within the hollow interior. Movement of the tether in the unwinding direction causes relative movement between the plurality of magnets and the conductor member. Eddy currents within the conduct member generate a retarding force on the first shaft.

摘要： A force limiting device for use with a safety belt retractor is provided. The safety belt retractor includes a spool and a safety belt webbing attached to and wound around the spool for payout of the webbing under the influence of forwardly directed movement of a vehicle occupant. The force limiting device comprises a fixed member, a shaft connected to the fixed member and a coupling received on the shaft and operatively connected to the spool. The coupling is configured to move along the longitudinal extent of the shaft towards the fixed member during payout of the webbing. Engagement of the coupling with the fixed member prevents further payout of the webbing. The shaft is configured to limit movement of the coupling along the shaft during payout of the webbing to control effective belt force on the vehicle occupant during a crash condition.

摘要： An energy absorbing device with torso displacement limiter to be applied to any seatbelt model is characterized by a laminated plate conveniently fastened to a retractor body of a seatbelt. The device presents predetermined resistance and malleability characteristics and is provided with a convenient number of folds arranged in parallel with respect to each other and transversally with respect to the longitudinal axis of the plate. The folds, when submitted to a certain traction strength resulting from a strong collision or sudden deceleration of a vehicle in which they are being used, are gradually unfolded, causing a gradual increase in the length of plate.
