Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a cover structure for a reclining device for an automobile.

(Prior art and its problems) Conventionally, as reclining devices for automobiles,
As shown in FIG. 3, a cushion bracket 2 fixed to a seat cushion 1 is connected to a back bracket 4 fixed to a seat bag 3 so as to be rotatable back and forth.

By the way, the cushion bracket 2 has the following:
Notch 5 that allows rotation of the back bracket 4
A cover member 5 having a shape is attached.

In order to prevent foreign matter such as dust from entering through the notch 5a or to improve the appearance, flocks 6 are provided on the side edges of the notch 5a to cover the entirety of the notch 5a. (Refer to Utility Model Application Publication No. 57-172554)
There were problems such as the dust that got into the gaps between the flocks 6 being scattered.

Therefore, as shown in FIG.
A flat member 7 covering the entire notch 5a is attached to the side edge of the notch 5a.
It has been proposed that a lubricant is applied to the area where the back bracket 4 comes into contact (in 1987).
(Refer to Publication No. 175140), if the gap between the flat plate member 7 and the back bracket 4 becomes too narrow due to manufacturing/assembly errors of the brackets 2, 4 and the cover member 5, when the back bracket 4 rotates, There were problems such as the flat plate member 7 being twisted and damaged.

(Purpose of the invention) The present invention has been made to solve the above-mentioned conventional problems, and in particular, it has been devised to improve the latter conventional technology and prevent damage from occurring due to manufacturing and assembly errors. be.

(Structure of the invention) Therefore, the present invention provides an automobile reclining device in which a cushion bracket fixed to a seat cushion is connected to a back bracket fixed to a seat back so as to be rotatable back and forth. A cover member having a notch portion that allows movement is attached to the cushion bracket, and the notch portion is attached to the side edge of the notch portion of the cover member via a thin hinge portion that is vertically swingable. An overhanging cover portion covering the entire body is integrally formed, and slits in the left-right direction spanning the overhanging cover portion and the thin hinge portion are formed at a predetermined pitch in the rotating direction of the back bracket. It is something.

(Operations and Effects of the Invention) The present invention has the following features:
An overhanging cover part is integrally formed via a thin hinge part, and a slit is formed across the overhanging cover part and the thin hinge part.

Therefore, even if the gap between the overhanging cover part and the back bracket becomes too narrow due to manufacturing or assembly errors of each bracket or cover member, the overhanging cover part will not touch the thin hinge part when the back bracket rotates. Since it can swing vertically using the fulcrum, the overhanging cover part will not be twisted and will not be damaged.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, a back bracket 14 fixed to a seat bag 13 is connected to a cushion bracket 12 fixed to a seat cushion 11 so as to be rotatable back and forth. A synthetic resin cover member 15 having a notch 15a that allows the back bracket 14 to rotate is attached.

As shown in detail in FIG. 2, an overhanging cover portion 15b that covers the entire notch portion 15a is integrally formed on the side edge of the notch portion 15a of the cover member 15.

The overhanging cover part 15b has a thinner wall on the side connected to the notch 15a than the free end side, and a thin hinge part 15c is formed on the connecting side, so that the overhanging cover part 15b can swing up and down. ing.

The back bracket 14 has slits 15d, .
It is formed with a predetermined pitch P in the direction of rotation.

With the above configuration, the overhanging cover portion 15b that covers the notch portion 15a of the cover member 15 is
Since each slit piece can swing vertically using the thin hinge portion 15c as a fulcrum, each bracket 1
2, 14 and the cover member 15, the gap between the overhanging cover 15b and the back bracket 14 is narrow, and even if the back bracket 14 comes into contact with the overhanging cover portion 15b during rotation, the overhanging cover will not close. Part 15b is back bracket 1
4 and swings vertically, so accidents such as damage will not occur.
