[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention is a shield cover structure for a reclining device in an automobile seat.
The present invention relates to a shield cover structure for covering a connecting portion between a lower arm and an upper arm in a reclining device for a vehicle seat having a lower arm fixed to a vehicle floor and an upper arm rotatably connected to the lower arm and fixed to a seat back.

2. Description of the Related Art Conventionally, in a vehicle seat, a lower arm fixed to a vehicle floor is connected to an upper arm fixed to a seat back by a reclining device, and a reclining device exposed to the outside is covered with a cover material. However, since the upper arm rotates with respect to the lower arm, the reclining device located at the connecting portion between the upper arm and the lower arm can cover the surface with the cover material, but the upper arm rotates around the surface. When doing
It catches on the lower arm. Therefore, the periphery of the reclining device cannot be covered with the cover material, the periphery of the reclining device is exposed to the outside, and the appearance is deteriorated. Further, in order to cover the circumference of the reclining device, a cover material separate from the cover material covering the surface of the reclining device can be used, but this requires a time for attaching the cover material and is economical. It was bad.
Therefore, an object of the present invention is to make it possible to surely and quickly cover the connecting portion between the upper arm and the lower arm with one cover member.

[0003]

In order to solve the above-mentioned problems, in the shield cover structure of the reclining device according to the present invention, the cover material is formed with a slide groove for moving and guiding the lower arm. The slit is provided to communicate with the outside. Since the cover material has a slit that connects the slide groove and the outside, it can be attached to the connecting part of the lower arm and the upper arm from the slit. Furthermore, since the slide groove is formed in the cover material, the lower arm Moves along the slide groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described with reference to FIGS. In a vehicle seat, a lower arm 2 is fixed to a vehicle floor 1, an upper portion 2a of the lower arm 2 is rotatably connected to a lower portion 3a of an upper arm 3 by a conventionally known reclining device (not shown), and the upper arm 3 is seated back. It is fixed to SB. Reference numeral 4 denotes a lock release wire for the reclining device. By operating this wire 4, the lock of the reclining device is released and the upper arm 3 becomes rotatable. The upper part 3b of the upper arm 3 is fixed to the side surface SB1 of the seat back SB with screws 5 and 5. The upper portion 2a of the lower arm 2 is connected to the lower portion 3a of the upper arm 3 on the seat back SB side surface thereof by the reclining device as described above. The lower arm 2 has a central portion 2b inclined outward from the upper arm 3 and a lower portion 2c standing upright outside the upper arm 3. Then, a synthetic resin cover material 6 is attached to the upper arm 3 with screws 10
The cover member 6 covers the connecting portion 7 between the upper arm 3 and the lower arm 2. The cover member 6 covers the surface of the connecting portion 7 and is composed of a flat plate portion 6a having an arcuate lower end and a bent portion 6b formed by bending the left, right end and lower end excluding the upper end of the flat plate portion 6a. A screw hole 8 for attaching to the upper arm 3 is formed in the upper portion of the portion 6a. Holes 6c and 6c, in which the heads of the screws 5 and 5 of the upper arm 3 are located when they are attached to the upper arm 3, are formed above and below the screw holes 8 of the flat plate portion 6a, respectively. At the lower portion 6g of the flat plate portion 6a, the upper arm 3
A slide groove 6d is formed in an arc shape so that the inclined central portion 2b of the lower arm 2 moves when the lower arm 2 rotates. Furthermore,
The flat plate portion 6a and the bent portion 6b are provided with slits 9 that communicate the slide groove 6d with the outside. Slide groove 6
The flat plate portion 6a and the bent portion 6b below the d are formed in the slide groove 6
The flat plate portion 6a located above d is located rearward of the circular portion 6e, and a gap 6f is formed between the circular portion 6e and the circular portion 6e.

In the shield cover structure having the above-described structure, since the slit 9 and the slide groove 6d are formed in the cover material 6, the connecting portion 7 between the upper arm 3 and the lower arm 2 is laterally (in the direction of the arrow in FIG. 1). The cover member 6 can be attached to the circular plate portion 6a of the flat plate portion 6a as shown in FIG.
e covers the surface of the connecting portion 7, and the lower portion 6g of the flat plate portion 6a and the bent portion 6b cover the periphery of the connecting portion 7. Since the lower portion 6g of the flat plate portion 6a is located rearward of the circular portion 6e, it is located inside the central portion 2b of the lower arm 2 and on the seat back SB side, and the central portion 2b of the lower arm 2 forms the slide groove 6d. Passing through. Then, as shown in FIG. 3, when the seat back SB tilts, the upper arm 3 rotates with respect to the lower arm 2, but a slide groove 6d is formed in the cover member 6 attached to the upper arm 3. Therefore, the central portion 2b of the lower arm 2 moves along the slide groove 6d, the lower arm 2 does not catch on the cover material 6, and the lower arm 2 moves smoothly.

EFFECTS OF THE INVENTION According to the present invention, the cover member is formed with the slide groove and the slit for communicating the slide groove with the outside. The cover material can also be covered with the cover material, and the cover material can reliably prevent exposure to the outside. Therefore, since the connecting portion is not exposed to the surface, the appearance of the connecting portion is improved. Further, since the work of covering the connecting portion is completed by inserting the cover material into the connecting portion through the slit, the workability is improved. Furthermore, because the cover material has a slide groove, when the upper arm rotates, the lower arm does not move along the slide groove and is not caught by the cover material, so the upper arm can rotate smoothly. You can do it.
