Description

[Detailed Description of the Invention] The present invention relates to an improvement of a slide bar for an automobile seat belt. In general, three-point seat belts for automobiles include webbing, one end of which is wound around a retractor attached to the vehicle body behind the front door of the automobile, and the webbing is passed through a suspension guide attached to the vehicle body above the retractor. It passes diagonally from the front of the front seat and is locked to a buckle attached to the inside rear of the seat, and further passes over the seat and is fixed to the vehicle body at the outside rear of the seat at its other end. The portion from the sash guide to the buckle constitutes a shoulder belt, and the portion from the buckle to the fixed end constitutes a waist belt. When the seat belt is not in use, the webbing is wound around the retractor and stored along the vehicle wall from the retractor through the sash guide to the fixed end.

By the way, in a two-door type car with a rear seat, the passenger in the rear seat tilts the backrest of the front seat forward and enters and exits from there. The part from the sash guide to the fixed end crosses the entrance/exit passage diagonally, and becomes extremely obstructive.

In JP-A-54-55922 and JP-A-57-74247, a slide bar is provided at the sill at the rear lower part of the door and extends forward and backward of the vehicle body, and the fixed end of the webbing is slid back and forth on the slide bar. It shows what can be attached freely. In this device, when the seat belt is in use, the webbing moves to the front end of the slide bar so that the seat belt is properly fastened, and when it is not in use, it moves to the rear end to facilitate the getting on and off of the rear seat passengers. It's about getting used to it. However, with these devices, the work of fixing the slide bar is troublesome, and when a large force is applied to the webbing, the slide bar may become distorted or damaged and cannot sufficiently support the force. , which was not desirable.

In view of these circumstances, the inventors first fixed only the front end of the slide bar to the car body, and the rear end was supported by being locked into a locking hole drilled in the car body, so that the slide bar could not be fixed to the car body. To provide a slide bar that is easy to use and can support a large force applied to webbing. FIG. 1 shows how this slide bar is used. Reference numeral 1 denotes a retractor, which is attached to the lower part of the inner wall of the vehicle body behind the door 2. A webbing 3, one end of which is wound around the retractor 1, extends upward, and a sash guide 4 is fixed to the upper part of the inner wall of the vehicle body. , passed diagonally in front of the front seat 5 , passed through the tongue piece 7 engaged with the buckle body 6 attached to the inside rear lower part of the seat 5 , and further crossed over the seat 5 . The free end 3a is attached to the slide bar 8 so as to be slidable back and forth. The webbing portion 3b extending from the sash guide 4 to the tongue 7 constitutes the shoulder belt of the seat belt, and the webbing portion 3c extending from the tongue 7 to the free end 3a constitutes the waist belt of the seat belt. It forms the seat belt.

The slide bar 8 is made by bending a round bar as shown in Figs. 2 to 4, and the front end is bent into a substantially O-shaped shape and the tip is flattened to form a fixing part with bolt holes. and is fixed to the vehicle body 10 at the bottom of the door 2 with bolts 9. The rear end of the slide bar 8 is bent in the direction approaching the vehicle body 10 to form a locking portion 8b, which is inserted diagonally into a locking hole 11 bored in the vehicle body 10 and locked.
Further, the tip thereof is bent upward to form a retaining portion 8d. Further, the fixed portion 8a and the locking portion 8b are connected by a rod-shaped portion 8d. A plugging tool 12 is fitted into the locking portion 8b, and the plugging tool 12 closes the locking hole 11. As shown in FIG. 5, this plugging tool 12 consists of a cylindrical portion 13 and a flange portion 14, and the cylindrical portion 13 is fitted into the locking hole 11.

However, generally, a flexible mat 15 is laid in the interior of a car, and the plugging tool 12 is installed on the mat 1.
5 is fitted into the locking hole 11 from above.
However, the mat 15 is flexible and does not necessarily conform to the shape of the floor surface and the lower part of the side wall of the vehicle body 10, and may float or undulate considerably against the inner surface of the vehicle body. many. Therefore, even if the flange 14 of the plug 12 is formed parallel to the inner surface of the vehicle body, it does not necessarily follow the inner surface of the mat properly, and may partially rise from the mat surface as shown in FIG. It tends to be.

The present invention was developed in view of the above circumstances, and it is an object of the present invention to provide a slide bar having a plug that can correctly follow the surface of the mat even if the mat is somewhat wavy.

FIGS. 6 and 7 show a plugging tool 12 used in the present invention, which is made of a flexible material and includes a cylindrical portion 13 and a collar portion 1.
4, there is a gap 16 between the cylindrical portion 13 and the flange 14, and the cylindrical portion 13 and the flange 14 are connected by a connecting piece 17.

FIG. 8 shows a state in which the hole plug 12 is attached to the locking portion 8b of the slide bar 8, and the locking portion 8b is locked in the locking hole 11 of the vehicle body 10. According to the present invention, the clogging tool 12 is made of a flexible material, and the cylindrical portion 13 and the flange 14 are connected only by the connecting piece 17, so that the flange 14 can easily swing relative to the cylindrical portion 13. can move. Therefore, when the slide bar 8 is attached to the vehicle body 10 via the mat 15, even if the mat 15 has some undulations, the collar 14 swings and is attached correctly along the surface of the mat 15. Part 14 is locally pine 1
There is no such thing as rising above the 5th surface.

Furthermore, since the flange portion 14 is swingable relative to the cylindrical portion 13, the plugging tool 12 can be easily fitted into the locking portion 8b even if the retaining portion 8d is formed at the tip of the locking portion 8b. can do.
