Abstract: A piston for a pretensioner device (10) for a motor vehicle seat belt system of a type having a gas generator (17) with the piston (21) guided in a tube (16) that closes a pressure space (20) in the tube (16). The pressure space (20) can be pressurized by the gas generator (17), driving the piston (21) to undergo pretensioning operation transmitted to the seat belt system by a force transmission means. The piston has a dome shaped front side adapted to engage a force transmission element and a skirt forming a sealing lip oriented toward the pressure space. At least one slot is formed in the outer surface of the piston extending axially from the sealing lip. The slot can be enlarged by the material erosion caused by the pressure and/or pressure conditions in the pressure space produced by gas from the gas generator.

Abstract: There is disclosed an air-bag unit mounted on a seat. The air-bag unit is connected to a mounting member which is secured to or forms part of the structure of the seat. The air-bag unit has a first set of locking formations and the mounting member has a second set of locking formations. The locking formations of one of the sets are apertures and the locking formations of the other of the sets are projections. Each aperture at least partially receives a respective projection. There is a spring mounted to either mounting member or air-bag unit so as to extend across each of the apertures and to form a snap-connection between the air-bag unit and the mounting member in the region of each aperture.

Abstract: A vehicle sensor device comprising: a weight body housing installed in a body so as to be rotatable around a shaft coupled to the body, a weight body being installed in the weight body housing, a ball assembly for sensing a change in inclination of a vehicle, a sensor housing in which the ball assembly is movably installed, and a sensor lever installed in the sensor housing and rotated by the movement of the ball assembly. The sensor lever is configured to linearly reciprocate, by rotation, a pilot lever provided in a locking device. The sensor lever is installed in the sensor housing to which the ball assembly is coupled. The sensor lever is rotated around a hinge shaft by the movement of the ball assembly according to a change in inclination of the vehicle to linearly reciprocate the pilot lever connected to the sensor lever.

Abstract: A steering wheel enabling support of an airbag module by distributing a load when the airbag activates to ensure prescribed deployment performance of the airbag without affecting the horn function. The steering wheel includes: a support unit that supports the airbag module enabling the airbag module to move along the Z-axis direction relative to the core metal; and a horn mechanism having a movable contact provided on the airbag module and a fixed contact provided on the pin of the support unit. When in a horn non-operating state, a stopper is separated by a distance D2 in the Z-axis direction relative to the airbag module and the distance D2 is farther than the distance D1 of the movable contact and the fixed contact in the Z-axis direction.

Abstract: A vehicle airbag device includes an inflator, a bag shaped airbag cushion, and a rectifying member on the inside of the airbag cushion. The rectifying member includes a bottom surface part into which the inflator is inserted, a roof part that, when a rim of a steering wheel is likened to a dial of a clock, extends in a 12 o'clock and 6 o'clock direction on the clock when seen from a driver regularly seated in a driver seat with the steering wheel in a neutral position, and opening parts and formed in the 12 o'clock and 6 o'clock positions. The roof part includes, when seen from a 9 o'clock direction, a top part that protrudes convexly toward a driver side, and ridge line parts and that extend in both the 12 o'clock and 6 o'clock directions of the clock from the top part in an inverted arch shape.

Abstract: A belt retractor having an electrically actuatable locking device comprising a housing with a base plate and an upright first limb, a locking lever mounted pivotably on the upright first limb with a steel plate which is spring-loaded, and an electromagnet arranged in the housing and having a coil with a through opening, a first iron core which is arranged in the through opening, when a voltage is applied to the coil, exerts a magnetic force on the locking lever via the steel plate and actuates the locking lever for triggering a locking or unlocking movement against the force of the spring. The movement of the locking lever is enforced by a first magnetic circuit formed by the first iron core, the upright first limb and the portions of the base plate and of the locking lever between the first iron core and the upright first limb.
