Description

[Detailed description of the invention] This invention is an interlocking mechanism for a reclining device.
In particular, it relates to a connecting piece that connects the operating lever of a reclining device and a wire interlocking with a slide lock mechanism of a seat cushion.

Conventionally, as shown in FIG. 1, a reclining device 1 for a vehicle seat has a seat back portion 2.
The base side of the mounting piece 3 attached to the seat cushion part 4 is locked to the seat cushion part 4 side, and this is connected to an operating lever 5 to adjust the inclination angle of the seat back part 2. In addition, an upper rail 6 provided on the lower side of the seat cushion portion 4 is slidably attached to a lower rail 7 fixed to the vehicle floor side.
A lock mechanism 8 is provided as means for preventing the upper rail 6 and lower rail 7 from sliding. Such a reclining device 1 is 2
In a door-type vehicle, a reclining device interlocking mechanism 9 is provided so that it can be operated from the rear seat side. In addition, the engagement state of the reclining device 1 can be released by the operation lever 10, and when the occupant in the rear seat steps on the operation lever 10 downward, the seat back portion 2 is simultaneously tilted toward the front side. The seat cushion part 4 slides toward the front side to form a space in which a rear seat occupant can easily get on and off from the front door. As shown in FIG. 2, this reclining device interlocking mechanism 9 has one end temporarily fastened to the wire 11 with a caulking 12, and the other end connected to the operating lever 10 side with a mounting piece 14 fixed with a pin 13. There is.

However, according to the conventional interlocking mechanism for a reclining device having such a configuration, the wire 1
1 and the mounting piece 14 is strong against tension in the direction in which the wire 11 extends.
1 will not be pulled out, but when attaching this mounting piece 14 to the operating lever 10, in order to hook it to the pin 13, it must be rotated in the inward and outward directions relative to the wire 11, or rotated in the up and down direction, and then crimped. 1
If force is applied to loosen the caulking part 12, the caulking part 12 will become loose, and due to repeated operations after installation, the attachment piece 14 and wire 11 will eventually become loose.
This had the disadvantage that the two parts were cut and separated.

The purpose of the present invention is to provide an interlocking mechanism for a reclining device as described above, in which a cylindrical body is fixed to the other end of the wire in a direction perpendicular to the wire, and a length that is longer and slightly wider than the cylindrical body in the extending direction of the connecting piece is provided. A bending method obtained by providing a hole, inserting the cylindrical body into the elongated hole, making it rotatable at right angles, and bending the connecting piece around the cylindrical body along almost the entire circumference of the cylindrical body. The above-mentioned drawbacks are eliminated by holding the cylindrical body between the parts, connecting the free end sides of the two stacked connecting pieces with a connecting member such as a rivet, and guiding the wire through the long hole. This will be explained in detail below using examples.

3 and 4 are perspective views showing an embodiment of the interlocking mechanism for a reclining device according to the present invention, and in the same figure, one end of the mounting piece 20 is a long metal piece on a disk portion. It is molded into 21,
A hole 22 into which a pin 13 of an operating lever 10 (not shown) is fitted is bored in the center of the disc portion 21. A long hole 23 extending in the length direction is formed near the center of the mounting piece 20.
Holes 25 are formed at both ends of the holder 3, into which rivets 24 for temporary tightening, which are connection members, are fitted. Also,
A cylindrical body 26 is fixed at right angles to the wire 11 at one end of the wire 11 connected to the slide lock mechanism of the seat cushion.
The elongated hole 23 is longer than the cylindrical body 26 and has a slightly wider width.

To explain the process of attaching the wire and the attachment piece in the above configuration, first, the cylindrical body 26 fixed to the tip of the wire 11 is inserted into the long hole 23 of the attachment piece 20.
After inserting the cylindrical body 26 in the direction shown in FIG.
At step 7, the cylindrical body 26 is bent in the X and Y directions along almost the entire circumference. Next, the holes 25 and 25 for the rivet 24 are aligned, and when the rivet 24 is inserted into the hole 25 and temporarily tightened, the cylindrical body 26 is held between the bent portions 27 as shown in FIG. After doing this, even if the mounting piece 20 is rotated in the direction of the arrow Z in order to attach the hole 22 to the pin 13, the mounting piece 20 and the cylindrical body 26 of the wire 11 are bent at the bent portion 27 as shown in the arrow W. Since it is rotatable, no excessive force is applied to this part.

In this embodiment, the disk portion 21 having the hole 22 for attachment to the operating lever 10 is attached to the attachment piece 2.
5, the present invention is not limited to this, and as shown in FIG.
1, and the cylindrical body 26 of the wire 11 is inserted into the elongated hole 33.
After the rivet 24 is inserted into the holes 35, 35, the rivet 24 may be inserted into the holes 35 and temporarily tightened, so that the cylindrical body 26 is held by the bent portion 37. By doing this, the connection with the operating lever 10 can be performed by the two disc parts 31, so the mounting piece 3
0 will be more firmly attached.

As explained above, according to the interlocking mechanism for a reclining device according to the present invention, one end is connected to a wire that interlocks an operating lever provided on a reclining device of a vehicle seat to a slide lock mechanism of a seat cushion. In the interlocking mechanism for a reclining device for a vehicle seat, the connecting piece has a hole at the other end into which a pin provided on the operating lever fits, and a cylindrical body is fixed to the other end of the wire in a direction perpendicular to the wire; An elongated hole that is longer and slightly wider than the cylindrical body is provided in the extending direction of the connecting piece, and after the cylindrical body is inserted into this long hole, it can be rotated at right angles, so that the cylindrical body can be rotated approximately at a right angle about the cylindrical body. The cylindrical body is held by the bent portion obtained by bending the connecting piece along the entire circumference, and the free end sides of the two stacked connecting pieces are connected with a connecting member such as a rivet, and the above-mentioned Since the wire is led out through the long hole,
Even if force is applied to the connection between the wire and the mounting piece in an unexpected direction, this force can be easily buffered by the bent portion and the cylindrical body, and the durable and durable mounting piece provides high reliability. An interlocking mechanism for a reclining device can be obtained.
