Description

[Detailed description of the invention] Various vehicle seats have been devised that are equipped with a reclining or moving mechanism that allow these operations to be performed selectively with a single lever or handle ( For example, see Utility Model Application Publication No. 158330/1983).

This invention relates to a vehicle seat operating device that reclines the backrest of a vehicle seat and moves the entire seat in the lateral direction, and each locking device is operated by a single operating lever. It is.

Next, the structure of the present invention will be explained with reference to embodiments shown in the drawings.

In order to recline the backrest of a vehicle seat (not shown), a locking device (mechanical free lock) 1 is provided on the side of the seat, and by pushing in a rod 2 protruding from the end of the locking device, the locking device is activated. When the lock is released, the inclination angle of the backrest can be changed.

In addition, in order to move the entire seat laterally, a locking device (mechanical free lock) 3 is provided below the seat, and by pushing in a rod 4 protruding from the end of the locking device, the locking device is released. The seat is moved along lateral rails (not shown) so that its lateral position can be changed.

A single operating lever 11 is provided to perform this reclining operation and lateral movement operation. In addition, an operating lever 12 is parallel to the operating lever 11.
are provided, and both are pivotally supported with the same rotation center on a frame 5 to which the seat is fixed. That is, the operating lever 12 and the operating lever 11 are inserted into the mounting bolt 13 with the washer 14 inserted, and then the washer 1 is inserted into the mounting bolt 13.
5, a mounting bolt 13 is inserted into the frame 5 and fixed with a nut 16. Therefore, the operating lever 11 and the operating lever 12 are designed to be able to rotate freely relative to each other around the mounting bolt 13.

A locking pin 17 is attached to the rod portion 12a of the operating lever 12.
is planted, and this is connected to the rod part 1 of the operating lever 11.
It is loosely fitted into a through hole 11b provided in 1a. That is, the inner diameter of the through hole 11b is made large enough to prevent the through hole 11b from coming into contact with the engagement pin 17 when the operating lever 11 is rotated to move in the lateral direction, as will be described later. .

The swinging lever 21 is rotatably attached to a pivot pin 22 implanted in the frame 5, and a pin 23 is implanted at the end of the rod portion 12b extending further from the rod portion 12b of the operating lever 12. It has been set up. A pin 23 is attached to one rod portion 21a of the swing lever 21.
However, a coil spring 24 is stretched between the rod portion 21a and the frame.
Due to this bias, the rod portion 21a and the pin 23 are always in contact with each other.

The other rod portion 21b of the swinging lever 21 is arranged so that the rod 2 provided on the locking device 1 is located close to and opposite to the other rod portion 21b.

Furthermore, in the operating lever 11, the operating lever 1
A roller 31 is rotatably attached by a pivot pin 32 to an edge portion 11c located on the opposite end side to the rod portion 11a on which the rollers 2 are attached in parallel.

The swinging lever 33 is rotatably attached to a pivot pin 34 implanted in the frame 5, and the roller 31 is in contact with one rod 33a of the swinging lever 33. A coil spring 35 is stretched between the rod portion 33b and the frame, and its bias causes the rod portion 33a and the roller 31 to constantly come into contact with each other.

The rod 4 of the lock device 3 is arranged to be close to and opposite to the rod portion 33b of the swing lever 33.

A handle 41 for operating the operating lever 11 is fixed to the end of the operating lever 11. By grasping and pushing down the handle 41, the backrest can be reclined, and by grasping and pulling up the handle 41, the seat can be moved laterally.

That is, when the handle 41 is pushed down, the operating lever 11 rotates in the direction B around the mounting bolt 13. At this time, the through hole 11b provided in the operation lever 11 is connected to the engagement pin 1 provided in the swing lever 12.
7 to move it in the C direction. Therefore, the swing lever 12 rotates about the mounting bolt 13, and the pin 23 implanted in the rod portion 12b moves in the D direction. The pin 23 is in contact with the rod portion 21a of the swing lever 21, and the pin 23 is in contact with the rod portion 21a of the swing lever 21.
When the rod portion 21a is pressed against the bias of 4, the swing lever 21 rotates about the pivot pin 22. Therefore, the other rod portion 21b rotates in the E direction and pushes in the rod 2 located opposite to it.
The lock device 1 is unlocked and the reclining operation can be performed freely.

At this time, since the rod portion 33b of another swinging lever 33 does not rotate close to the rod 4, the locking device 3 does not operate at all and only the locking device 1 is operated. .

Also, when the handle 41 is pulled up, the operating lever 11
rotates in the F direction around the mounting bolt 13. At this time, the roller 31 attached to the edge 11c of the operating lever 11 moves in the G direction. The roller 31 is in contact with the rod portion 33a of the swing lever 33, and when the roller 31 presses the rod portion 33a against the bias of the coil spring 35, the rod portion 33a rotates in the H direction. Therefore, the other rod portion 33b rotates in the J direction and pushes in the opposing rod 4, thereby releasing the locking of the locking device 3 and allowing the seat to be moved freely in the lateral direction.

At this time, the operating lever 11 rotates in the F direction and the through hole 11b also moves upward, but the operating lever 11
2, so that the hole 11b and the engaging pin 17 are not in contact with each other.
and never engage. So the swing lever 21
Since the rod portion 21b does not rotate close to the rod 2, the locking device 1 does not operate at all and only the locking device 3 is operated.

In the embodiment described above, the rod 2 of the lock device 1 is arranged to face the rod portion 21b of the swing lever 21, and the rod 4 of the lock device 3 is arranged to face the rod portion 33b of the swing lever 33. Rod part 2
The rod 4 of the locking device 3 is opposed to the rod 3 of the locking device 1b.
3b may be opposed to the rod 2 of the locking device 1. Further, although the rods 2 and 4 have been described, instead of the rods, a receiving piece may be connected to the end of the inner cable that slides inside the hollow outer cable, and the receiving piece may be pushed into it.

As mentioned above, the present invention uses a single operation lever to recline the backrest of the seat and move the entire seat in the lateral direction. Because it is designed to be used separately,
It's extremely easy to operate. Since the operating lever is single and does not take up any extra space around it, the appearance is clean and the installation location can be selected as appropriate. Further, when the structure is such that only one of reclining and lateral movement is operated, parts can be shared, and the armrest to which this is attached can also be of a common structure.
