A webbing retractor for taking up an occupant-restraining webbing used in a seat belt apparatus for a vehicle has a takeup shaft held by a frame, and the webbing is wound around the takeup shaft. The takeup shaft is pivotally held at a substantially intermediate portion of each of a pair of arms. One end of each arm is pivotally supported by a support shaft, and the arms are adapted to rotate about the support shaft. At the time of a sudden deceleration of the vehicle, a clamp plate held at a distal end of a clamp lever is pushed upward by an actuating device including the arms to cause the webbing to be clamped, and when a clamping force exceeding a predetermined value is applied to the webbing, a projection formed at a proximal end of the clamp lever presses a thin-walled portion toward a rectangular hole so as to deform the thin-walled portion, which in turn causes the clamp plate to move in a direction in which the clamped state of the webbing is canceled, thereby setting a webbing-clamping force at a predetermined level or below.

Webbing retractor

A seat for use in a vehicle equipped with an automatic seatbelt system includes a seat cushion for supporting the buttocks of an occupant. The seat cushion is provided with a passage for a webbing of the seatbelt system. Accordingly, it is possible to prevent the contact between the webbing and the seat cushion when the webbing is wound up into and unwound from a webbing retractor.

Seat for vehicle

A webbing intermediate portion retaining apparatus for use in an automatic seatbelt system for a vehicle arranged such that, when an occupant enters the vehicle, an occupant restraining webbing is automatically fastened to the occupant's body, whereas, when the occupant leaves the vehicle, the webbing is automatically unfastened from his body. The apparatus enables the intermediate portion of the webbing to be retained by a hook provided on a door of the vehicle when the occupant leaves the vehicle. The apparatus effects control such that, when the occupant is going to leave the vehicle, the hook is moved to a position for retaining the intermediate portion of the webbing, whereas, after the occupant has entered the vehicle, the hook is moved to a position for canceling the retaining of the intermediate portion of the webbing. Accordingly, when the occupant enters and leaves the vehicle, it is possible to ensure a sufficient space for him to move smoothly.

Apparatus for retaining intermediate portion of webbing

An automatic system for use in a motor vehicle has an outer webbing, both ends of which are secured to a vehicle door and an inner webbing, one end of which is connected to the intermediate portion of the outer webbing through a ring joint movable along the outer webbing and the other end of which is retracted by a retractor on a vehicle floor. A guide lever is provided at an inner side of an occupant's seat, which includes a main body fixed to the inner side of the seat and a webbing guide portion on the top of the main body. The webbing guide portion has an opening through which the inner webbing passes and is rotatable around an axis extending laterally of the vehicle, whereby the webbing guide portion presents a suitable position and angle to guide the inner webbing at any condition, for example, with or without an occupant on the seat.

Automatic seatbelt system

A ring joint for connecting the intermediate portion of an outer webbing to the forward end portion of an inner webbing to fasten the webbings about an occupant in a three-point type seatbelt system, wherein stoppers erected from a joint base prevents the axial movement of a lock bar, whereby, in an emergency situation of a vehicle, the lock bar locks the intermediate portion of the outer webbing between the joint base and itself to prevent the outer webbing from moving in the longitudinal direction thereof, so that an occupant can be reliably restrained.

Ring joint for seatbelt system

A resilient member for biasing a webbing takeup shaft in a direction of retracting a webbing, after the webbing is fastened about an occupant, is driven in a direction of reducing the biasing force by a returning device, whereby the winding force acting on the webbing is reduced, so that an oppressive feeling rendered to the occupant can be reduced. After the webbing has been unfastened from the occupant, the returning device drives the resilient member in a direction of increasing the biasing force to retract the webbing to a fully retracted state.

Automatically fastening seatbelt system, wherein an anchor plate engaged with one of restraining webbings is connected through a support device to a driving force transmitting member and made movable along a guide rail, whereby the webbings are automatically fastened to an occupant, a release device is provided at a predetermined position in the longitudinal direction of the guide rail, and the operation of the support device is released by the operation of the release device to release the anchor plate from the guide rail.

Automatically fastening seatbelt system

An automatic seatbelt system which has a flexible tape extending continuously along a vehicle body form a roof side portion through a center pillar to a door so as to move a shoulder webbing connected to the roof side portion and a lab webbing connected to the door at the same time by a single driving sprocket wheel in response to an occupant entering or leaving a vehicle. The tape has a plurality of openings along the longitudinal direction thereof and the sprocket wheel is meshed with the tape by the openings. A shoulder guide rail is provided along the roof side portion of the vehicle body, within which a shoulder guide member guiding the shoulder webbing and connected to the trape is slidably received. A lap guide rail is provided along the door, within which a lap guide member guiding the lap webbing and connected to the tape is slidably received. When the sprocket wheel rotates, both shoulder and lap seatbelt webbings are simultaneously moved through the tape toward either the front side of the vehicle to provide an enough space for the occupant to enter the vehicle, or the rear side of the vehicle to place the webbings over the occupant at a seat.

An automatic seatbelt system in which a pair of sprocket wheels are driven by a single driving motor to move both shoulder and lap webbings in response to an occupant entering or leaving a vehicle. A flexible shoulder tape is connected to the shoulder webbing through a guide member slidable along a roof side of the vehicle, and extends along a vehicle body to mesh with one of the sprocket wheel. A flexible lap tape is connected to the lap webbing through a guide member slidable along an inner surface of a vehicle door, and extends along the vehicle door and body to mesh with the other of the sprocket wheel. When the sprocket wheels rotate, both shoulder and lap seatbelt webbings are simultaneously moved through the tapes toward either the front side of the vehicle to provide an enough space for the occupant to enter the vehicle, or the rear side of the vehicle to place the webbings over the occupant at a seat.

The tape has a plurality of openings along the longitudinal direction thereof and the sprocket wheel is meshed with the tape by the openings. The tape extends continuously between the vehicle body and vehicle door and has a stepped portion substantially extending in a vertical direction, for example, a direction which is aligned with the rotation center of door hinges so as to twist itself around the longitudinal center thereof during opening or closing the door. When the sprocket wheel rotates, both shoulder and lap seatbelt webbings are simultaneously moved through the tape toward either the front side of the vehicle to provide an enough space for the occupant to enter the vehicle, or the rear side of the vehicle to place the webbings over the occupant at a seat.

A conventional type of seat belt retractor having a pendulum control to lock protraction of belt webbing in event of vehicle impact is modified to provide also manual control of webbing protraction by including a lever unit that can engage a pawl of the ratchet wheel mechanism that locks the shaft on which the webbing winds and a coil spring or similar member that resiliently connects the lever unit to the pawl. The modified seat belt retractors are useful in locking baggage, child seats or the like on the vehicle seat.
