Patent attributes
To provide rider restraint means capable of allowing a rider to freely leave a vehicle without a manual release operation when there is no need to restrain the rider to the vehicle. The rider restraint means includes a belt restraining a rider, buckles making the belt detachable, a guide rail making the buckles slidable, a retractor unit controlling the slide of the buckles, and coupling release means releasing coupling between the belt and the buckles in conjunction with the slide of the buckles. The coupling release means includes an inner wire, a wire stopper, and a wire end. The coupling release means releases the coupling between the belt and the buckles when the retractor unit loosens the winding after collision and the buckles slide by a predetermined distance or more or when the rider continues to pull the belt in a state other than collision and the buckles slide by a predetermined distance or more.
