Description

[Detailed description of the invention] This invention relates to a self-supporting buckle for seatbelts installed in automobiles, especially tangless seatbelts (belts with no insert piece for the buckle), and the belt can be unhooked from the buckle. The purpose is to facilitate.

To explain the drawings, 1 is the car body, 2 is the seat, 3 is the backrest, 4 is the upper end of the car body 1, and the lower end of the seat 2.
The tongueless seat belt 5 fixed to the seat 2 is a self-supporting buckle body fixed to the side of the seat 2 in a standing state, and the buckle body 5 is provided with a hook 6 for hooking the middle of the belt 4.

The upper end of the belt 4 may be fixed to the shoulder of the backrest 3.

In the present invention, the hook 6 for hooking the tongueless seat belt is inserted into the self-supporting buckle main body 5 via the leg rod 61 so as to be vertically slidable, and the hook 6 is inserted between the hook leg rod 61 and the buckle main body 5. A locking device 8 is provided between the buckle body 5 and the hook 6 or its leg rod 61 to hold the hook 6 in the lowered position.

In the illustrated example, a tension coil spring is provided as the spring 7, but a compression coil spring may also be used.

Although the structure of the locking device 8 is arbitrary, the illustrated example includes a rotation retainer 81 for the tip claw portion 62 of the hook 6, a release lever 8□ that can be engaged with and detached from the engagement member 8□, and the lever 8.
It consists of two back fits 83.

When the belt 4 is released, the hook 6 is extended upward by the action of the spring 7, as shown in FIGS. 1 and 2, and is released.

To attach the belt 4, follow the chain line 41 in Figure 3.
The claw 6□ of the hook 6 that has descended engages the rotary retainer 81 to close the hook 6, and a release lever is attached to the engager 8□. 8□ engages to fix the engaging element 81 and maintain the attached state of the belt 4.

When the release lever 8□ is pushed with a finger to release the rotary holder 81, the hook 6 rises until it hits the stopper 9 by the force of the spring 7, and the belt can be removed from the hook 6.

The self-standing buckle for the seat belt of the present invention has a hook 6 for a belt hook that can be slid up and down on the free-standing buckle body 5, which is installed near the side of the seat 2 while standing. The structure includes a locking device 8 that holds the belt 6 in the depressed position, and a spring 7 that automatically raises the hook 6 when the belt is released. It is raised to a high position on the side of the seat 2, and the belt 4 can be easily unfastened.

In the attached state, the hook 6 is stored at a low position on the side of the seat 2, so it does not interfere with driving, and is effective as an improvement on the self-supporting buckle for a tongueless seat belt.
