Description

[Detailed Description of the Invention] This invention relates to a hinge cover for an automobile seat, and more particularly to a hinge cover for an automobile seat in which a seat back is tiltably supported on a seat cushion.

Generally, in an automobile seat, a seat back is tiltably supported by a seat cushion via a hinge arm, so that the inclination angle of the seat back with respect to the seat cushion can be changed and adjusted.

Further, in the case of the above-mentioned automobile seat, a hinge cover with one side open is attached to cover the pivot portion between the seat cushion and the seat back.

By the way, the hinge cover is formed with a notch for operating the hinge arm on the top open side, and the hinge arm is made to swing in the notch. Therefore, when adjusting the inclination angle of the seat back,
There have been cases where fingers or clothing have been caught between the notch of the cover and the hinge arm.

Therefore, as shown in FIG. 5, the present inventor formed an elastic protector 3 to fill the gap between the notch 1a of the hinge cover 1 and the hinge arm 2, and directed the protector 3 downward toward the top inner wall of the cover 1. The protruding rod 1b is inserted into the protruding rod 1b.
The protector 3 is attached to the hinge cover 1 by fitting a nut spring 1c to the end of the arm, and the protector 3 prevents fingers or clothes from being caught between the notch 1a and the hinge arm 2. I thought about doing it.

However, in the hinge cover 1, the mounting strength of the elastic protector 3 is not sufficient, and due to the elastic deformation of the protector 3 caused by the swinging of the arm 2, the protector 3 may fall inward of the cover 1 or turn over. The results were sluggish and the effect could not be achieved.

When the hinge cover 1 is formed, it is formed by injection molding or other molding means using a mold, and the cover 1 is formed by cutting out the cover 1 from the mold in the left and right direction of the opening. If the protrusion 1b for attaching the protector is provided on the top inner wall of the cover 1 in a direction perpendicular to the die cutting direction, it is extremely difficult to die the cover 1. Therefore, in this case, it is necessary to mold the cover 1 using a special mold such as a slide core, but this mold is very expensive.
Moreover, it is necessary to move the mold in different directions, ie, in the left-right direction of the opening of the cover 1 and in the vertical direction to cut out the projection rod 1b, making the operating mechanism of the mold complicated and large. It is.

The present invention has been developed based on the above ideas, and it is possible to securely and firmly attach the elastic protector to the hinge cover without causing the elastic protector to fall down or roll up, and to prevent the elastic protector from falling or rolling up. To reliably prevent objects such as objects from being caught between a hinge cover and a hinge arm, and to easily manufacture the hinge cover.

More specifically, a notch for operating the hinge arm is provided on the top open side of a cover body with one side open, and a mounting arm facing toward the open side is provided inside the side of the body, while the notch and the hinge An elastic protector is formed to fill the gap between the arm and the protector, and the protector is provided with a contact part that contacts the inner surface of the top part of the body, and a mounting part that extends toward the mounting arm, and the mounting part is connected to the mounting arm. It is characterized by being fixed to the mounting arm.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The hinge cover for an automobile seat according to the present invention will be described below with reference to the drawings.

The automobile seat shown in the drawing has a seat back B tiltably supported behind a seat cushion A via a hinge arm 2, so that the inclination angle of the seat back B with respect to the seat cushion A can be changed and adjusted. A hinge cover 1 is attached to the sides of the pivot parts of the cushion A and the seat bag B to cover the pivot parts.

Thus, the hinge cover 1 is formed as follows.

That is, a cover body 1d with one side open is formed, and a notch 1a for operating the arm 2 extending in the swinging direction of the hinge arm 2 is provided at the top of the body 1d on the side of the open part 1e. 1
A mounting arm 1f is provided on the inner side near the top of the opening 1e.

and a cutout portion 1a of the cover body 1d;
An elastic protector 3 made of rubber or the like is formed to fill the gap with the hinge arm 2, and the protector 3 has a contact portion 3a that comes into contact with the inner surface of the top portion of the body 1d.
and a mounting portion 3b extending toward the mounting arm 1f side of the body 1d.

Thus, the contact portion 3a of the protector 3 was brought into contact with the top inner surface of the body 1d, and the attachment portion 3b of the protector 3 was brought into contact with the tip of the attachment arm 1f, so that the attachment portion 3b was provided. Multiple mounting holes 3
By screwing the fixing screw 4 from c toward the mounting arm 1f, the protector 3 is attached to the body 1d.
The protector 3 is attached toward the notch 1a side to close the gap between the notch 1a and the hinge arm 2.

As described above, the protector 3 is provided with the contact portion 3a and the attachment portion 3b, the contact portion 3a is brought into contact with the top inner surface of the cover body 1d, and the attachment portion 3b is fixed to the attachment arm 1f of the body 1d. As a result, even if the protector 3 is elastically deformed due to the swinging of the arm 2, the protector 3 can be reliably and firmly supported without causing the protector 3 to fall or curl up.

The cover body 1d is formed by injection molding using a mold, and is formed by cutting out the body 1d in the left-right direction of the open portion 1e. At this time, the mounting arm 1f is Since it is provided on the inner side of the body 1d toward the open portion 1e, that is, in the direction in which the body 1d is cut out, the body 1d can be molded very easily.

It is preferable that the working surface 3d of the protector 3 that comes into contact with the hinge arm 2 is inclined so that the distal end of the notch is lower than the mounting side of the body 1d, as shown in FIG. When the arm 2 swings, the protector 3
becomes easier to climb onto arm 2, that is, arm 2
This allows for smooth rocking.

As explained above, in the hinge cover of the present invention, the notch for operating the hinge arm is provided on the open side of the top of the cover body, and the mounting arm facing the open side is provided on the inner side of this body. Since an elastic protector is formed to fill the gap between the body and the hinge arm, and the protector is attached to the mounting arm of the body, the protector closes the gap between the notch of the body and the hinge arm and prevents the arm from swinging. During movement, that is, when adjusting the angle of the seat back, it is possible to prevent fingers or clothing from being caught between the arm and the body notch.

Moreover, in the present invention, the protector is provided with a contact portion that contacts the inner surface of the top portion of the body, and a mounting portion that extends toward the mounting arm side of the body, and the contact portion is brought into contact with the inner surface of the top portion of the body, Since the protector is attached to the body by fixing the mounting part to the mounting arm, even if the protector is elastically deformed due to the swinging of the hinge arm, the protector will not fall into the body or turn up. The protector can be reliably and firmly attached to the body without slipping, and therefore the purpose of attaching the protector can be fully achieved.

In addition, in this invention, the mounting arm for attaching the protector is formed on the inner side of the body facing the open side, that is, in the direction of mold removal during body molding, so it can be used without using a special mold. It can be manufactured extremely easily using a mold.
