An embodiment seat belt mounting structure includes a front seat disposed towards a front of a vehicle body, a rear seat disposed towards a rear of the vehicle body, a center pillar part, a rear pillar part disposed behind the center pillar part, a side reinforcement connecting the center pillar part and the rear pillar part, and a rear seat retractor coupled to the side reinforcement.

A buckle includes a main body part that can be coupled to a tongue that is attached to a seatbelt of a vehicle; a communication substrate to which one end of a wire harness is coupled, the wire harness passing through an opening formed on a buckle surface of the buckle; a holder configured to support the communication substrate; and a cover configured to cover the main body part, the communication substrate, and the holder. The cover includes a rib that prevents the holder from moving in an opening direction of the opening.

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.

A motor vehicle (1) has a seat (7), a seatbelt (8), a deflector (5), longitudinal and vertical guide rails (2, 4), and first and second guide elements (3, 9). The seatbelt (8) is configured to secure a person seated in the seat (7) and is deflected by the deflector (5). The first guide element (3) is guided displaceably in a longitudinal direction (L) of the motor vehicle (1) in the longitudinal guide rail (2). The vertical guide rail (4) is fastened to the first guide element (3) and is displaced upon displacement of the first guide element (3). The second guide element (9) is guided displaceably in a vertical direction of the motor vehicle (1) in the vertical guide rail (4). The deflector (5) is fastened to the second guide element (9) so that the deflector (5) also is displaced upon displacement of the second guide element (9).

Provided are a pretensioner, a retractor, and a seat belt device that can effectively reduce kinetic energy of an injected power transmission member. A power transmission unit includes a power transmission member that is engageable with external teeth of the ring gear, a pipe that contains the power transmission member, a gas generator that is disposed at an end of the pipe, a piston that receives gas generated from the gas generator to press the power transmission member, a first stopper that is disposed on an upstream side of the power transmission member, a second stopper that is disposed between the power transmission member and the piston, and a pretensioner cover that defines a passage for the power transmission member.
