  • Patent number: 5588608
    Abstract: A pretensioner is disclosed which, when a vehicle suddenly decelerates, a large quantity of gas is generated, and the gas flows into a cylinder from a gas-generating a device. As a result of pressure of the gas, a movable pulley moves instantaneously together with a piston, so that the wire trained around the movable pulley is pulled. An amount by which a wire is pulled is twice an amount by which a wire is pulled in cases where the wire is directly connected to the piston, as in conventional devices. Accordingly, the wire can be pulled by the same amount by using only half of a length of a conventional cylinder, thus making it possible to manufacture a pretensioner which has a short cylinder.

  • Patent number: 5538284
    Abstract: When a vehicle accelerates to a predetermined value, a pretensioner mounted to an occupant seat applies a pulling force to a seat belt under a force produced by detonating an explosive material. When the seat is moved in the longitudinal direction of a vehicle in order to adjust the position and the seat comes to a halt at a frontal end position, an acceleration more than or equal to the predetermined value is developed in an acceleration sensor. However, the acceleration sensor is provided with a lock means mounted to the seat. Even if the seat suddenly stops at the frontal end position, the acceleration sensor is restrained from moving and the pretensioner is not actuated. The lock means is actuated even when a walk-in mechanism for directly moving the seat to the frontal end is operated.

  • Patent number: 5195694
    Abstract: A preloader adapted to forcibly pull a webbing in a taking-up direction when the vehicle suddenly decelerates, so as to allow the webbing to be applied closely around an occupant. A clamp member for clamping the webbing is provided to prevent a subsequent tight winding of the webbing. The clamp member is constantly urged in a webbing-clamping direction by an urging member, and is normally held in a position spaced apart from the webbing against an urging force of the urging member. As the holding is canceled after the forcible taking up of the webbing, the clamp member is capable of clamping the webbing.

  • Patent number: 5174521
    Abstract: A preloader for use in a webbing retractor for retracting an occupant-restraining webbing onto a takeup shaft so as to allow the webbing to be applied to the occupant with appropriate tightness. A rotating drum disposed coaxially with the takeup shaft has an annular groove. A wedge member is held around the rotating drum at a certain distance from the rotating drum by a shear pin. A wire is wound in advance around the outer periphery of the wedge member. At the time of a sudden deceleration of a vehicle a driving force is applied to the wire, and the wire in turn tightens the wedge member by being more tightly wound therearound. The shear pin is broken by the tight winding by the wire, and the wedge member is wedge-fitted to the rotating drum, so that the wedge member and the rotating drum rotate integrally and cause the takeup shaft to rotate.

  • Patent number: 4993656
    Abstract: A webbing retractor which, when a webbing is drawn out instantaneously, prevents the drawing out of the webbing by operating a lock mechanism. In addition, when a vehicle is decelerated suddenly, the drawing out of the webbing is also instantaneously prevented by causing a pawl to engage with a lock wheel preventing the lock wheel from rotating. The webbing retractor includes a lever which is swung in such a manner as to be movable between a first position in which the pawl is made unengageable with the lock wheel and a second position in which the pawl is made engageable with the lock wheel. The webbing retraction also includes a lever swing member which causes the lever to be located in the first position as the take-up shaft rotates in a webbing taking-up direction and to be situated in the second position as the take-up shaft rotates in a webbing draw-out direction. Accordingly, the pawl is prevented from engaging with the lock wheel at a take-up limit of the webbing.

  • Patent number: 4436255
    Abstract: A seatbelt retractor for use in a motor vehicle to retract a passenger restraining seatbelt to be fastened around an occupant. The seatbelt is wound around a rotatable takeup shaft in layers by a biasing force in the seatbelt retractor. Fixed on the takeup shaft is a ratchet wheel, and a pawl is opposed to the ratchet wheel, whereby when the pawl meshes with the ratchet wheel, and thereby stops the belt-unwinding rotation of the takeup shaft. An inertia lock mechanism is provided in the retractor to actuate the pawl to mesh with the ratchet wheel in a vehicular emergency situation. A cam mechanism is also provided in the retractor, which includes a cam member or ring rotated by the takeup shaft and a follower member or linear spring driven by the cam member and opposed to the pawl. The cam member actuates the follower member to move the pawl into engagement with the ratchet wheel when the seatbelt is unwound more than a predetermined value, namely a value necessary for the fastening of the seatbelt.
