In a webbing retractor, due to operation of a pretensioner mechanism, a stopper wire is moved, and second lock pawls of a second lock base mesh-together with an inner ratchet of a lock ring. In this way, a limit load by a torsion shaft can be switched to a high load. Therefore, immediately after operation of the pretensioner mechanism, the limit load by the torsion shaft can be made to be to the high load, and the limit load can be made to be the high load at an early stage.

A webbing retractor has two torque transmitting routes for taking-up, such that rapid and reliable taking-up, and gentle taking-up are possible. When an engaging claw of a pawl restricts rotation of a ratchet plate, due to planetary gears rotating around a sun gear, rotation is transmitted from a drive gear to a carrier plate. On the other hand, when restriction of rotation of the ratchet plate is released, a clutch spring tightens around a tube portion of the carrier plate while rotation of the drive gear pulls one peripheral direction end of the clutch spring in a direction of rotation thereof. Frictional resistance between the tube portion and the clutch spring is increased, and rotation is transmitted from the drive gear to the carrier plate.

A webbing winding device in which a breadth dimension of a torque limiter is less than an axial direction dimension of an external gear. A rotation disc, the torque limiter or the like is wholly disposed, along a radial direction of the external gear, between the external gear and a peripheral wall of a baseplate. Further, members such as pawls, a rotation disc and the like are disposed, along a radial direction of the peripheral wall, between the peripheral wall and an adaptor, and these members are accommodated at an inner side of the external gear. Consequently, a thickness dimension (axial direction dimension) of a clutch is practically the same as an axial direction dimension of the external gear, and this is extremely thin.

A steering wheel which has a ring shaped rim and is connected to a steering shaft of a vehicle via a hub, comprising a supporting member which is formed independently of the rim and the hub, is connected to the rim for supporting the same from inside, and can deform by a load at a predetermined value or more from the vehicle occupant side of the vehicle. Accordingly, in the steering wheel, when kinetic energy from the body of the vehicle occupant due to inertia at the time of a rapid deceleration of the vehicle acts on the steering wheel, and presses the rim of the steering wheel by a pressing force (a load) at a predetermined value or more, the supporting member for supporting the rim from inside thereby deforms. As a result, kinetic energy of the body of the vehicle occupant due to inertia at the time of the rapid deceleration of the vehicle can be absorbed.

An air bag apparatus having a bag body inflated due to gas generated at the time of a sudden deceleration of a vehicle; a plate for holding the bag body; an oblong hole formed at a portion of the bag body where the bag body is not inflated; a rivet inserted into the oblong hole; and a pressing piece for holding the bag body via the rivet between the bag body and the plate in a state in which the bag body is not inflated when the vehicle is running at an ordinary state and for pressing the bag body so as to allow the bag body to be inflated when the vehicle suddenly decelerates. As a result, the bag body is moved along the longitudinal direction of the oblong hole when the vehicle suddenly decelerates, allowing the bag body to be inflated.

An air bag device is equipped with a restricting member for preventing an air bag accommodated in an air bag main body from being inflated erroneously upon impact before the air bag main body is attached to a body of a vehicle inclusive of a steering wheel. This restricting member, only when a deactivating member for deactivating the operation of an acceleration sensor is in operation, allows the air bag main body to approach a designated attaching area of the body of a vehicle. After the air bag main body is secured, the operation of the deactivating member is released to the put the acceleration sensor in an operation activating condition.

A webbing lock apparatus includes a fixed lock member and a movable lock member which is disposed such as to face the fixed lock member. The movable lock member is moved while being guided by a guide in a direction diagonally crossing the webbing wind-off direction so that a webbing is clamped between the same and the fixed lock member. A high degree of acceleration at the time of a vehicular emergency which is detected by an acceleration sensing means is transmitted to the movable lock member through a movable arm, whereby the webbing is clamped between the fixed and movable lock members. It is, accordingly, possible to effect a reliable webbing lock operation by the use of a small-sized acceleration sensing means.

A webbing tension adjusting apparatus is arranged such that, when the occupant leaves the vehicle, a motor is rotated forwardly, and a takeup shaft for winding up an occupant restraining webbing thereon is thereby rotated in the webbing wind-off direction through a one-way clutch which is interposed between the motor and the webbing takeup shaft. Accordingly, the webbing is quickly wound off when the occupant leaves the vehicle, so that the webbing tension is reduced. Thus, it is possible to decrease the amount of friction or rubbing which occurs between the sliding webbing and the clothes of the occupant.

In a webbing guide structure, when a take-up stopper has made abutted to a contact face of a webbing guide due to take-up force acting on a webbing arising from a spiral spring of a webbing take-up device, a rigid portion of the webbing extends out from the webbing guide towards the vehicle front-side, and a portion of the rigid portion further towards an tip end than the take-up stopper projects out from the rear seat back to the vehicle front-side. Due to utilizing biasing force of the spiral spring to project the rigid portion out from the rear seat back to the vehicle front-side, the need to provide a separate mechanism to project the rigid portion out can accordingly be eliminated. A gap between the rear seat back and the webbing can thereby be provided by employing a simple structure.

A webbing take-up device enabling a reduction in size of an overload release mechanism and easy adjustment of an operation torque of the overload release mechanism is provided. In the overload release mechanism of this webbing take-up device, rotary force of a large diameter gear is transmitted to a small diameter gear via plural annular friction springs. The friction springs are disposed between an inner periphery face of a main body portion of the large diameter gear and a tubular portion of the small diameter gear, side by side along an axial direction of the two gears. Consequently, a radial direction enlargement of the large diameter gear and small diameter gear due to space for disposing the friction springs may be restrained. Moreover, the operation torque of the overload release mechanism may be adjusted stepwise by changing the number of the friction springs to be used, in accordance with requirements.
