BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a device for engaging a seat belt with a vehicle body for protecting a driver when an impact force is generated due to a collision or the like in a vehicle such as an automobile.

[0002]

2. Description of the Related Art In an automobile, a seat belt device is mounted to protect a driver when an impact force is generated due to a collision or the like.

As shown in FIG. 4, the seat belt device includes a seat belt 1 having ends fixed to two portions of a vehicle body.
Is inserted into the fitting hole 2a of the stopper 2, and then the stopper 2 is fitted into the engaging member 4 of the vehicle body to stop the driver 3
The chest and the waist are tightened to prevent the driver 3 from being thrown forward by the inertial force at the time of a collision.

In such a seat belt device, when the seat belt 1 is not used, the stopper 2 is engaged with the engaging member 4 of the vehicle body.
When the seat belt is removed from the vehicle, the seat belt is accommodated in the pillar by a winding spring (not shown) built in the pillar of the vehicle body. For this reason, when the seat belt is used, the chest and waist of the driver 3 are appropriately tightened by the tension of the winding spring.

[0005]

In the above-described vehicle seat belt device, when the driver uses the seat belt, the driver's body 3 is fastened by the seat belt 1, so that the driving time of the vehicle becomes longer (generally). (1 hour or more), the waist portion of the driver 3 becomes congested due to the fastening of the seat belt, and the driver 3 feels tired.
For this reason, at present, during long-time driving, the driver 3 is driving while relaxing the seat belt 1 with his / her hand.

On the other hand, if the tension of the wrapping spring of the seat belt is reduced to reduce the above-mentioned effects on the body, the seat belt is not sufficiently housed in the pillar portion when the seat belt is not used, and the seat belt is not used. At times, the position of the seat belt on the chest of the driver 3 is not determined, and the function as a safety device is lost.

[0007] Accordingly, an object of the present invention is to prevent excessive tightening force from being applied to a driver when a seat belt is used, to prevent driver fatigue during long-time driving, and as a safety device. It is an object of the present invention to provide a seatbelt device capable of fully exhibiting the function of the seatbelt.

[0008]

SUMMARY OF THE INVENTION A seat belt device according to the present invention is inserted into an engaging member provided on a vehicle body, a stopper which is engaged with and disengaged from the engaging member, and a through hole formed in the stopper. A seat belt fixing mechanism applied to a seat belt device including a seat belt having both ends fixed to a vehicle body, and an annular mounting portion having a fitting hole formed to fit the stopper. A spring-like portion extending from the attachment portion, a wedge-like portion formed at an extension end of the spring-like portion and capable of being fitted into and removed from the insertion hole; The wedge-shaped portion is inserted into the insertion hole in a state where the fitting hole is fitted, so that an arbitrary portion of the seat belt can be locked to the stopper.

[0009]

When the seatbelt is used, the wedge-shaped portion of the seatbelt locking member is pushed into the seatbelt fitting hole of the stopper, and the seatbelt is locked in the fitting hole by the wedge-shaped portion.

Therefore, when the driver feels tired at the waist during long hours of driving, the part on the waist side of the belt is loosened while wearing the seat belt, and in this state, the wedge-shaped portion is fastened to the seat of the fastener. If the seatbelt is pushed into the belt fitting hole and the seatbelt is locked, it is possible to operate the vehicle with the chest side part slightly loosened while maintaining the normal tension at the chest side part.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; However, unless otherwise specified, dimensions, materials, shapes, relative positions, etc. of the structural components described in this embodiment are not intended to limit the scope of the present invention thereto, but are merely illustrative examples. It's just

1 to 3, reference numeral 10 denotes a seat belt locking member, which is made of a flexible material such as soft plastic or hard rubber.

The seat belt locking member 10 includes an annular mounting portion 10a, a wedge-shaped portion 10c, and the mounting portion 10a.
A spring-shaped part 10b connecting the wedge-shaped part 10c and a fitting hole 10d formed in the mounting part 10a of the spring-shaped part 10b is fitted into the body part 2b of the fastener 2 of the seat belt 1 so that Mounted.

The wedge-shaped portion 10c formed at the front end of the seat belt engaging member 10 is formed in a wedge shape with a sharp end, as shown in FIG. The wedge-shaped portion 10c has a thickness and a width such that the wedge-shaped portion 10c can be pushed into the insertion hole 2a of the stopper 2 with the seat belt 2 inserted.

As shown in FIG. 2, the spring-like portion 10b has appropriate elasticity so that the wedge-like portion 10c can be easily inserted into and removed from the insertion hole 2a by input.

The driver 3 engages the engaging portion 2c of the stopper 2 of the seat belt 1 with the engaging member 4 of the vehicle body, as shown in FIG. Then, the waist is fastened by the seat belt 1 with an appropriate tension to drive the automobile.

The tension of the seatbelt 1 is set to a size such that when the seatbelt 1 is detached by a winding spring (not shown), the seatbelt 1 can be sufficiently stored in a pillar portion in a vehicle. .

When the driver 3 feels tired at the waist while driving for a long time with the seat belt 1 fastened, the driver 3 moves to the waist side as shown in FIG. After the seat belt 1b is loosened by a required amount, the wedge-shaped portion 10c of the seat belt locking member 10 is pushed into the insertion hole 2a of the stopper 2 by a finger or the like, and the seat belt 1 is locked in the insertion hole 2a. Let me know.

As a result, the driver can relax the waist-side seat belt 1b by a required amount and reduce the tension without substantially changing the tension of the chest-side seat belt 1a. It is possible to continue driving for a long time without feeling tired.

In order to remove the seat belt 1b on the lumbar side and remove the seat belt 1b from its original state, as shown in FIG. When the (waist side seat belt 1a) is pulled, the wedge-shaped portion 10c of the seat belt engaging member 10 moves in a direction to be disengaged from the seat belt fitting hole 2a of the stopper, so that the thoracic and waist side seat belts 1a can be easily obtained. , 1b can be equalized. Further, since the seat belt locking member 10 is still attached to the stopper 2, the state where the tension of the seat belt 1 can be changed as described above is maintained as necessary.

The wedge-shaped portion 10c of the seat belt engaging member 10 naturally causes the seat belt 1
Can be locked in the insertion hole 2a of the stopper at an arbitrary portion, so that the tension of the seat belt 1 can be finely adjusted.

In the above embodiment, the seat belt 1b on the waist side is used.
The case where the seat belt 1 is loosened is shown.
When a is loosened, it is of course possible to implement the same method as described above.

[0023]

As described above, according to the present invention, the tension of the seatbelt can be freely adjusted by the seatbelt engaging member mounted on the fastener of the seatbelt. It is possible to prevent the seat belt tightening tension from acting, thereby preventing the driver from being fatigued.

In addition, since the locking portion of the seat belt can be easily changed, fine adjustment of the tension becomes possible. Furthermore, the seat belt locking member can be attached without changing any members of the existing seat belt device, and a simple and low-cost mechanism can be used to eliminate driver fatigue while ensuring safety. Can be. And so on.
