A seatbelt device bezel includes: a communication opening path that is in communication with a webbing pass-through portion of a bezel main body and that extends along a direction intersecting the webbing pass-through portion and opens at an outer edge of the bezel main body; a main body receiving portion that is disposed on both width direction sides of the communication opening path and that is integrally formed to the bezel main body; and a closing member that is mounted to the communication opening path and closes off the communication opening path, and that includes a clamping portion that clamps the main body receiving portion from one side and another side in the webbing pass-through direction.

In a through anchor (10), when an occupant is restrained by webbing (30) in a vehicle emergency, the webbing (30) is moved to the vehicle front side in an insertion hole (22) of a guide piece (18) by movement of the occupant due to inertia, and a vehicle front side end face of the webbing (30) contacts a peripheral face of the insertion hole (22) at high load. A gap is formed between the guide piece (18) and an anchor plate (12). The guide piece (18) is accordingly moved to the vehicle front side with respect to the anchor plate (12) by the webbing (30), thereby enabling occurrence of skewing of the webbing (30) toward the vehicle front side in the insertion hole (20) to be suppressed.

A webbing height adjusting device connected to a main webbing extending out from a webbing retractor of a seat belt system of a vehicle has a shock absorbing component and a webbing height adjusting unit. The shock absorbing component has a D-loop, a supplementary webbing, and an elastic element connected to the supplementary webbing for shock absorbing. The webbing height adjusting unit has an adjuster base, a slider, an elastic member, and an outer shell. The main webbing is mounted through the D-loop and the adjuster base; the supplementary webbing is mounted through the webbing height adjusting unit and clamped by the slider and the adjuster base pressed by the elastic member. The outer shell allows an operator to move the slider and the adjuster base relatively so as to unclamp the supplementary webbing and adjust the height of a top position formed by the webbing height adjusting unit.

A safety belt sliding assembly includes: an upper decorative plate having a first surface, in which the first surface is provided with a first guide rail and a second guide rail connected to each other, and the second guide rail is inclined in a direction running away from the first guide rail and in a direction facing away from the first surface; and a sliding plate including a fixed section and a flexible section connected to each other, wherein the fixed section and the flexible section are slidably fitted with the first guide rail, respectively, and the flexible section is configured to slide to the second guide rail and generate deformation.

Disclosed is a vehicle seat including a first seat portion serving as a seatback or a seat cushion according to rotation thereof, a second seat portion connected to the first seat portion and serving as a seatback or a seat cushion according to rotation thereof, a rotation shaft allowing the direction change of the seat when the first seat portion and the second seat portion rotate by connecting the first seat portion and the second seat portion and providing a rotation center for the first seat portion and the second seat portion, a first fixing device and a second fixing device respectively provided in the first seat portion and the second seat portion, and a seatbelt including a webbing and a coupling device connected to the webbing and allowing the passenger to be restrained from both front and rear directions of the seat by engaging the coupling device with the first fixing device or the second fixing device according to the direction change of the seat.

The vehicle seat includes a seat frame, a belt guide attached to the seat frame, and a coupling member coupling the belt guide to the seat frame. The seat frame is provided with a first locking portion extending in a first direction, and the belt guide is provided with a first receiving hole extending in the first direction and through which the first locking portion passing, and a second receiving hole extending in a second direction orthogonal to the first direction and receiving a part of the coupling member. The coupling member received in the second receiving hole engages the first locking portion passing through the first receiving hole.

The disclosure provides a shoulder strap width adjustment mechanism (40) comprising: a rail device (44), arranged on a seat backrest (22), including a first rail (441) and a second rail (442) arranged on both sides of the seat backrest (22) and extending substantially in a longitudinal direction, and a lateral distance between the first rail (441) and the second rail (442) gradually changes in the longitudinal direction; and two shoulder strap fixing members (42), connected to a seat headrest (30) and positioned between the seat headrest (30) and the seat backrest (22), and being slidable respectively along the first rail (441) and the second rail (442) of the rail device (44). In the disclosure, the shoulder strap width can be adjusted synchronously during the process of adjusting the height of the headrest, so as to meet the requirements of children of different heights and different body types.
