摘要： There is provided a webbing take-up device in which a load required to rotate a spool in a webbing drawing direction with reference to a shaft is stabilized in the process of rotating the spool, a stable load can be achieved with small deformation, and miniaturization can be achieved. In an ordinary state, an EA plate keeps its original shape, and the shaft and spool are rotated together with each other. When the shaft is prevented from being rotated in the webbing drawing direction in vehicle sudden deceleration, the EA plate is plastically deformed by a webbing drawing force, and the EA plate is pushed in an internal-angle portion of the spool with rotation of the spool in the webbing drawing direction with reference to the shaft. The EA plate is bent by a U-shaped portion and then wound around the outer periphery of the shaft. The other end portion of the EA plate is pushed into the internal-angle portion at a winding start end portion of the EA plate around the shaft to prevent the subsequential rotation of the spool in the webbing drawing direction with reference to the shaft. Thus, when the webbing is prevented from being drawn, the webbing is drawn by a predetermined length, and energy absorption can be achieved.

摘要： A webbing retractor comprises a spool around which a webbing capable of being unwound therefrom is wound; a pretensioner for rotating said spool in a webbing winding direction when a deceleration of a predetermined value or more is applied during a sudden deceleration of a vehicle; an energy absorbing member put in a coupled state with said spool, rotated integrally with said spool and deformed by said spool to prevent an increase in tension of the webbing when rotational force in a webbing unwinding direction acts upon said spool after said spool has been rotated in said webbing winding direction by said pretensioner; and a cancelling portion applied with the rotational force in said webbing unwinding direction via said energy absorbing member when the energy absorbing member is deformed by the rotational force in said webbing unwinding direction, for cancelling the state in which rotation of said spool in the webbing unwinding direction is stopped by said pretensioner. Therefore, after the spool is rotated in the webbing winding direction by the pretensioner, the spool is rotatable in the webbing unwinding direction.

摘要： In a push-type safety lever, a contact surface between a safety lever and a trigger lever is slanted. In a rotation-type safety lever, its circumferential surface is gradually increased in radiuses from an area in which a safety lever does not contact a trigger lever to an area in which it contacts the trigger lever. A mechanical ignition sensor is thereby provided so as to prevent the safety lever and the trigger lever from catching on each other and to reliably operate the safety device.

摘要： Upon a sudden deceleration of a vehicle, if an inertial body moves a predetermined amount against the urging force of a return spring, the trigger means will be released from engagement with the firing pin. Under the urging force of a spring, the firing pin is released from engagement with the trigger means, strikes and ignites a detonator so as to activate the actuator. The trigger means will not move until the inertial body has moved by the predetermined amount. Only after the inertial body has moved the predetermined amount, will the trigger means start to move suddenly and quickly. Therefore, friction at the time the inertial body engages the trigger means is kept constant. The stable operation of the sensor is thereby assured.

摘要： Shear ribs are formed at a bottom portion of a fitting hole of a spool for positioning a lock base, and respective end portions of the positioning portion abuts on a shear rib. Further, ribs are formed between the shear ribs. When the spool rotates in an unwinding direction with respect to the lock base, the end portion of the positioning portion deforms and breaks a shear rib, a rib and then another shear rib in that order. By being able to combine the effects of energy absorption due to deformation of the ribs with that of energy absorption due to twisting deformation of the torsion bar, a force limiter load immediately increases as soon as the spool starts to rotate.

摘要： A lock plate (46) chatter preventing structure which, under a predetermined condition, directly or indirectly engages with a take-up shaft that takes up a passenger-restraining webbing belt to deter the rotation of the take-up shaft in a webbing belt pullout direction. The lock plate chatter preventing structure includes: a support member that rotatably supports the lock plate (46); and an urging portion (128) formed continuously from the support member. The urging portion includes a leading end (128B) that pressingly contacts one axial-direction end portion (116) of the lock plate and urges the lock plate toward the other axial-direction end.

摘要： A fixture is disclosed which can reliably attach an attachment member, such as a cylinder, to an attachment site, such as a frame. The fixture includes a fixing portion, which faces the attachment site at the side of the attachment site and is fixed to the attachment site, and a contact portion, which is disposed at the side opposite from the attachment site, with the attachment member therebetween. The contact portion is integrally coupled to the fixing portion, point-contacts or line-contacts the attachment member, and is configured to push the attachment member to the attachment site in a state where the fixing portion is fixed to the attachment site. A webbing take-up device including this fixture is also disclosed.

摘要： In an automatic seat belt apparatus, a first tape is connected to a drive source. A second tape is connected to a slider and transmits a driving force from the drive source to the slider via the first tape. When a webbing is applied, a slide piece abuts a stopper. The slide piece moves relatively with respect to a lock plate against an urging force of a compression coil spring. Along with movement of the slide piece, the maintenance of the tapes at a connected position of the lock plate is cancelled. The lock plate rotates due to the urging force of the compression coil spring, and a separated position, at which the first tape and the second tape are separated, is maintained.
