A belt deflector having a main element which is fastenable to a vehicle structure, and a belt contact element which is movable in relation to the main element and forms a belt contact face or belt contact edge for a seat belt that is to be deflected. The belt deflector has a deformable intermediate element which, during movement of the belt contact element relative to the main element in the direction of the intermediate element, is deformed and is pressed against the seat belt. The belt contact element forms a mating clamping face, and a belt strap portion of the seat belt is arranged between the intermediate element and the mating clamping face. During the relative movement, the intermediate element presses the belt strap portion onto the mating clamping face.

A seat belt device includes a webbing, a locking tongue, and a guide. The webbing includes a lap belt and a shoulder belt. The locking tongue is configured to undergo a change from a free state, in which the webbing is capable of passing between a side of the lap belt and a side of the shoulder belt, to a lock state, in which the webbing is not capable of passing between the side of the lap belt and the side of the shoulder belt, in accordance with a collision or a warning of the collision of a vehicle. The guide is configured to, in accordance with the collision or the warning of the collision of the vehicle, displace a location on the shoulder belt that is adjacent to the locking tongue in a direction away from the occupant before the change to the lock state is completed.

In the buckle device, when or after torsional deformation of the torsion shaft has started and allowance of the drawing-out of the belt has started, the breaking portion of the shear plate is started to be deformed by the coupling hole side surface of the spool, whereby the breaking portion allows the rotation of the spool and allows the drawing-out of the belt. Therefore, the allowable drawing-out load of the belt can be made the sum of the load for torsionally deforming the torsion shaft and the load for deforming the breaking portion, and can be increased.

In a buckle device, when a belt starts to be allowed to be drawn, a fracture portion is deformed by a side surface of a connection hole of a spool, so that the fracture portion allows a rotation of the spool and allows drawing of the belt. Then, the fracture portion is fractured by the side surface of the connection hole. Therefore, a drawing allowance load of the belt when the belt starts to be allowed to be drawn can be increased.

A harness system with a buckle restraining function is provided and includes an upper buckle, an upper strap and a restraining device. The upper strap slidably passes through the upper buckle and includes a waist portion and a shoulder portion divided by the upper buckle. The restraining device utilizes an anti-sliding structure with high friction coefficient for engaging with the upper strap and further utilizes a stopping component for abutting against the upper buckle, which effectively restrains the upper buckle from sliding relative to the upper strap toward the waist portion for preventing a passenger's injury due to an excessive decrease of a length of the waist portion when the shoulder portion is forced during a collision or an emergency brake of a vehicle.

In a locking tongue (10) for a seat belt comprising an inserting portion (12) adapted to be inserted in a belt buckle and a deflecting portion (14) for webbing, wherein the deflecting portion (14) includes a webbing passage (20) as well as a damping element (22) for the webbing and the clamping element (22) is movable between a home position in which the webbing is freely movable and a blocking position in which the clamping element is moved against a wall of the webbing passage so that the webbing is clamped between the clamping element (22) and the wall of the webbing passage (20), and wherein at least one spring element (34) is provided for forcing the clamping element (22) into the home position, it is provided that the spring element (34) is formed integrally on the deflecting portion (14).

An apparatus includes a mounting plate having at least one deformable opening arranged to receive a securing member. The opening is configured to deform when a load on the mounting plate exceeds a predetermined threshold. The apparatus includes a ring member connected to the mounting plate. The ring member includes an opening to receive a strap there-through.
