摘要： A gas generating device for use in a vehicle in the event of a collision has a hammer pin, a gas generator and a hammer pin trigger device. The gas generator includes a detonator, which is accommodated in a housing for being fired when struck by a hammer pin, and a gas-generating chemical reagent arranged in adjacent to the detonator. In the event of a collision of the vehicle, the hammer pin trigger device causes the hammer pin to strike the detonator. The gas generator has a cover arranged to substantially close an opening in the detonator. The opening faces the hammer pin trigger device. The cover has a hammer pin insertion hole configured to receive the hammer pin. The hammer pin insertion hole of the cover has an inner diameter not greater than 1 mm to prevent leakage of high-temperature and high-pressure gas, which is produced as a result of explosive burning of said gas-generating chemical reagent, to the side of said hammer pin trigger device.

摘要： A retractor for use with a seat belt is capable of releasing a state of end lock easily without using a complicated structure of the lock operation means for operating the lock means in the case of an emergency of a vehicle. There are provided pawls (16, 13) capable of checking the rotation of the bobbin (3) in the webbing drawing direction when the pawls are engaged with inner teeth (2a, 2c) arranged on the side plates (1a, 1b) of the retractor base (1). The pawls (16, 13) are supported so that they can be relatively moved with respect to the bobbin (3) in the rotational direction of the winding shaft by a predetermined distance. In the normal operation, the ratchet wheel (18) follows the rotation of the bobbin (3). When the ratchet wheel (18) is relatively rotated with respect to the bobbin (3) in the webbing winding direction, the pawls (16, 13) are engaged with the inner teeth (2a, 2c). When the pawls (16, 13) are relatively rotated with respect to the bobbin (3), one end of the oscillating lever member (20) to reverse the ratchet wheel (18) in the webbing winding direction is connected to the ratchet wheel (18), and the middle portion is engaged with the pawl (16), and the other end is engaged with the bobbin (3).

摘要： A retractor for a seat belt includes a winding force reducing mechanism for reducing a webbing winding force when an occupant wears the seat belt. The retractor includes a base; a winding shaft supported rotatably on base for winding a webbing; a first winding spring for energizing the winding shaft in a webbing winding direction; a second winding spring disposed on the winding shaft in parallel to said first winding spring; and gear unit interposed between the winding shaft and the second winding spring for applying the energizing force of the second winding spring to the winding shaft in the same direction as the energizing force of the first winding spring and for tightening the second winding spring in an elastic energy storing direction by means of the energizing force of the first winding spring. The gear unit is structured such that, when the seat belt is in use, the elastic energy of the second winding spring stored therein can act in a manner to cancel the energizing force of the first winding spring so that a reduced energizing force in the webbing winding direction can be applied to the winding shaft.

摘要： A safety mechanism is provided for a mechanical trigger device of a gas generator. The mechanical trigger device has an inertia body, which is displaceable upon application of a deceleration of at least a predetermined value, and a mechanical trigger for actuating the gas generator in response to a displacement of the inertia body. The safety mechanism comprises a device for selectively setting the trigger in a first state where the trigger is operative or in a second state where the trigger is prevented from operation. This setting device has a member displaceable between a first position where the trigger is set in the first state and a second position where the trigger is set in the second state. The safety mechanism also comprises a cover member for being mounted to cover the setting device. This cover member has mount-preventing member for interfering with the displaceable member located in the second position so that mounting of the cover member is prevented.

摘要： An overlock prevention mechanism for a vehicle acceleration sensor used on a retractor for a seat belt device in a vehicle comprises an inertial body which moves in response to acceleration of the vehicle; a sensor casing on which the inertial body is mounted; a ratchet wheel which locks the retractor; and a composite sensor arm assembly comprising an upper sensor arm which is adapted to be engaged with the ratchet wheel and a lower sensor arm which is adapted to come into contact with the inertial body to transmit the movement of the inertial body to the upper sensor arm; and when the upper sensor arm is interlocked with the ratchet wheel, the lower sensor arm is forced toward the inertial body by a force activated from the ratchet wheel and transmitted through the upper sensor arm, so that the inertial body is pressed to the sensor casing against movement.
