A webbing support apparatus being capable of changing a support height of a webbing to be wound around an occupant of a vehicle, which is provided with a slider for supporting the webbing and being movably supported in a vertical direction in a guide rail, and the slider is provided with a restricting member which is engaged with the guide rail during its downward movement to prevent a downward movement of the slider more than a predetermined value. Accordingly, the slider can be positively lowered step by step.

Webbing support apparatus

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

A webbing retaining structure is employed in an automatic seatbelt system for a vehicle which is so designed that one end portion of a webbing which is closer to the outside of the vehicle is moved in the longitudinal direction of the vehicle, and the webbing is thereby automatically fastened to the body of an occupant. A first member which retains the end portion of the webbing is pivotally supported by a second member which is mounted on the vehicle body. A combination of a projection and recesses in which it is selectively fitted is provided between the first and second members. The angle at which the webbing is retained by the vehicle body can be adjusted by changing the position of combination between the projection and the recesses.

Webbing retaining structure

In a webbing lock device, there are provided a pair of lock members for clamping the intermediate portion of an occupant restraining webbing so as to bring an occupant into a restrained state in the event of an emergency situation of a vehicle, and resin material deformable in accordance with irregularities on the surfaces of the webbing, when the webbing is clamped, is provided on the surface of at least one of the lock members, whereby frictional resistances between the webbing and the lock members are increased and concentration of stress is avoided.

Webbing lock device

A webbing lock device in which an occupant restraining webbing extending from a takeup shaft of a retractor is clamped between a pair of clamping members by closing an interval therebetween, when an abrupt tensile force acts on the webbing as in the event of an emergency situation. Each of the clamping members has a corrugated surface on opposed side thereof and concave portions of one of the corrugated surfaces are disposed to correspond to convex portions of the other of the corrugated surfaces. An interval between the corrugated surfaces progressively decreases toward the takeup shaft along the longitudinal direction of the webbing, and the radius of the curvature of the corrugated surfaces, for example, is progressively smaller toward the takeup shaft, whereby clamping force to the webbing between the corrugated surfaces progressively increases toward the takeup shaft along the longitudinal direction of the webbing and there is no point where tensile force acting on the webbing abruptly decreases or increases to break the webbing.
