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 ring joint used in a three-point seatbelt system having an outer webbing and an inner webbing, interposed between the intermediate portion of the outer webbing and the forward end of the inner webbing and adapted to allow the outer webbing to move freely in the longitudinal direction thereof in a normal condition, but preventing the outer webbing from moving in an emergency. Furthermore, a guide means prevents the inner webbing from moving in the widthwise direction thereof relative to the ring joint, whereby the inner webbing is not shifted in the widthwise direction thereof in an emergency, thereby enabling an occupant to be secured in a positively restrained state.
