摘要： A pre-tensioner of a seat belt device capable of securely and rapidly transmitting torque between a driven shaft and a rotational ring when the pre-tensioner is activated. The driven shaft projecting from a reel for retracting a seat belt is inserted into a housing and the rotational ring is positioned to surround a gear of the driven shaft. The rotational ring is provided with five guide faces in the inner surface thereof and pins are inserted into pocket portions of the rotational ring. Each pin is held at the both ends by an annular portion of a body and a cover. Stepped portions are formed along peripheries of both ends of each guide face to form spaces.

摘要： A seat belt pretensioner of the type which rotates the take-up shaft of a retractor in the belt-winding direction so as to wind a length of the belt onto the retractor reel includes a driven gear connected to the retractor take-up shaft and a driving gear connected to a power source, the driving gear normally being held in clearance from the driven gear in the set condition of the pretensioner and being displaced and rotated upon operation of the power source to engage it with the driven gear and to drive the driven gear in rotation. The teeth of one of the gears have addenda that diverge from the addendum circle in the direction of the root circle and in a direction with respect to the direction of rotation of the driving gear such as to facilitate movement of the driving gear into driving engagement with the driven gear in the event of a collision of the addenda of the two gears.

摘要： A retractor shaft-rotating type seat belt pretensioner for imparting pretension to a seat belt by rotating the take-up shaft of a belt retractor comprises a driving member engageable with a driven member on the take-up shaft and a power source coupled to the driving member and adapted to rotate the driving member by applying an operating force to it at an operating point. A guide surface supports the driving member at a reaction support point against the reaction force due to a rotary moment applied to the driving member at an engaging point where the driving member engages the take-up reel, the reaction support point being on the opposite side of the engaging point from the operating point where the operating force of the power source acts on the driving member.

摘要： A belt pretensioner is provided for a vehicle safety belt system having a retractor from which and onto which a belt is arranged to be unwound and wound by rotation of a reel shaft. The pretensioner includes a pulley carrying a pulley gear and is ordinarily restrained in a position in which the pulley gear does not engage a shaft gear on the reel shaft and a pulling cable having a pulley-engaging segment wound onto the pulley and having a pulling segment leading from the pulley in a pulling direction to a power source arranged to pull on the cable and translate the pulley to engage the pulley gear with the shaft gear and rotate the pulley such the gears rotate the reel shaft and pretension the belt by winding it onto the reel shaft. The pulling cable has a pulled segment leading away from the pulley-engaging segment from the end thereof opposite the pulling segment in a direction substantially aligned with the pulling direction. A portion of the pulled segment frictionally engages fixed braking surfaces on the retractor. The pulley is restrained by the pulling and pulled segments of the pulling cable in a position in which the gears are not engaged.

摘要： A mechanical igniter for a gas generator has a weight, a latch lever and a firing pin as movable elements to fire a percussion cap attached to the gas generator in response to acceleration, and further has a restraint member and a controller therefor as a safety device for making the movable elements immovable. The controller can be activated by attaching the mechanical igniter to the vehicle body, or removing a belt stopper after the mechanical igniter has been attached to the vehicle body, or fastening a seat belt to the occupant's body. Thus, the restraint member is released when the mechanical igniter is attached to the vehicle body, or when the seat belt system is used, thereby automatically and safely releasing the safety device for the igniter.

摘要： A mechanical acceleration sensor includes a sensor casing, a weight, a spring-loaded firing pin, and a latch lever, the weight, the firing pin, and the latch lever, each being movably mounted in the sensor casing in such a manner as to either translate along an axis or to rotate about an axis, the axes of translation of the members that translate being substantially perpendicular to that the axes of rotation of the members that rotate. The latch lever is loaded with a set load to engage the firing pin and is positioned to be engaged by the weight upon inertial movement of the weight to disengage from the firing pin, thereby allowing the firing pin to perform a percussive firing action by the spring load. The casing has an opening for receiving the weight, firing pin and latch lever, and shaft support grooves are provided in the casing such that each shaft support groove is open at an end thereof which faces the opening. A shaft for a member that rotates is supported by the shaft support grooves.

摘要： A buckle pretensioner for a vehicle seat belt system of the type that is mounted on a vehicle seat includes a blocking device for preventing the movement of a movable member of an inertial starting mechanism that controls the operation of the pretensioner from releasing the pretensioner driving device. The blocking device includes a solenoid and an electric power circuit for energizing the solenoid having a seat slide switch that is responsive to movement of the seat release lever for controlling the energy state of the solenoid so that the blocking device prevents movement of the movable member in response to operation of the seat release lever to release the seat for adjustment and a delay circuit for maintaining the energy state of the solenoid established by operation of the seat slide switch for a predetermined period of time after the seat slide switch has been operated. The power circuit may also have a switch that is responsive to insertion of a buckle tongue into the buckle for controlling the energy state of the solenoid such that the blocking device prevents movement of the movable member of the inertial starting mechanism when the buckle tongue is not inserted into the buckle.
