摘要： A seat belt device has a gas generator for generating a high pressure gas when the vehicle is in emergency, a cylinder for conducting the high pressure gas from the gas generator, a piston received movably within the cylinder and pressed and moved by the high pressure gas, and a drive unit for rotating a winding shaft of a seat belt retractor in a direction of removing the slack of a belt, using the movement of the piston, wherein the pretensioner is employed with the energy absorbing mechanism, for reversely rotating the winding shaft if a tension acting on the belt exceeds a predetermined value after removing the slack of the belt.

摘要： In a retractor with a clamp mechanism for holding a webbing directly in a vehicle emergency, the retractor provides a movable clamp member for holding the webbing between the lower plate and the clamp member, and a guide member for guiding the clamp member to a webbing holding position, in which the clamp member includes a clamp teeth portion for clamping and engaging the webbing with a webbing opposing surface of the clamp member, a plane portion located on an opposite side to the webbing opposing surface, and a rear end side edge provided on a rear end side of the plane portion, and in which the guide member includes a sliding contact surface for sliding contact with the plane portion of the clamp member and a deforming portion deformable substantially in parallel to the webbing opposing surface of the clamp member. A movable wedge-shaped clamp member may be provided with a hold portion including a clamp teeth portion formed in a shape capable of biting into a surface of the webbing and shearable and deformable by a tensile force of a predetermined value or greater, and including a pressure teeth portion capable of applying resistance to the webbing moved in the webbing draw-out direction by a tensile force of a predetermined value or greater.

摘要： The present invention provides a seat belt system in which it is unnecessary to increase a distance of movement of the occupant's body by increasing a length of the seat belt to be drawn out more than it is required, so that an impact given to the occupant can be effectively reduced even in a vehicle in which an intensity of impact tends to increase. There is provided a fuse belt (5) on the lap belt (26b) located close to the anchor plate (14). When a tension, the intensity of which is higher than a predetermined value, is given to the continuous webbing (26), the lap belt (26b) is drawn out. In the retractor (10) having a clamp, there is provided an energy absorbing mechanism. When a tension, the intensity of which is higher than a predetermined value, is given, a holding force to hold the continuous webbing (26) is released and the shoulder belt (26a) is drawn out while a constant drawing force is being kept. Further, the predetermined value at which the lap belt (26b) is drawn out by the action of the fuse belt (5) is set to be lower than the predetermined value at which the shoulder belt (26a) is drawn out by the energy absorbing mechanism of the retractor (10).

摘要： In a seat belt winding device with a clamping mechanism for directly holding a webbing in an emergency of a vehicle, since the plastic deformation is repeated in stages in both of a clamp supporting device and plastically deforming members, a larger amount of kinetic energy can be absorbed on the side of the seat belt winding device. Further, when the webbing holding by the clamping mechanism is removed, not only the diameter of a plastically deforming member of a bobbin can be reduced greatly since the plastically deforming members project in the radial direction of the bobbin, but also the deforming direction of the plastically deforming members due to the tightening of the webbing can be specified because end surfaces of the plastically deforming members are respectively formed in an inclined surface Which is inclined in a specific direction. This allows the substantial winding diameter of the bobbin to be reduced uniformly and positively.
