As a result, the first and second locking devices can be unlocked and the rear legs can be folded in sequence by rotating the handle and operating the operating member while gripping the handle.

(Effect of the invention) Therefore, according to the invention, when folding the seat, the first and second locking devices are unlocked and the rear legs are folded in sequence while holding the rear leg folding handle. Since it can be easily performed with a one-touch operation, the operability of folding the sheet can be greatly improved.

(Example) Hereinafter, an example as a specific example of the technical means of the present invention will be described based on the drawings.

1 to 5 show the structure of a rear seat A of a wagon type automobile according to an embodiment of the present invention. The seat cushion 2 is made up of a seat cushion 2 and a seat back 3 provided in an upright position at the rear of the seat cushion 2. The front part of the seat cushion 2 has left and right front legs 4 that can be bent freely.
It is rotatably connected forward to the floor 1 via 4, and a pair of left and right rear legs 5,
is rotatably mounted, and the rear part of the seat cushion 2 is connected to the floor 1 via the rear legs 5, 5.

The pair of left and right rear legs 5, 5 are connected to each other at their lower portions via a connecting rod 6, and the lower end of one (left side in the figure) of the rear legs 5 is engaged with a locking member 11, which will be described later. The possible hook member 7 is the support shaft 8
The hook member 7 is rotatably attached via the hook member 7.
A spring (not shown) attached to the outer periphery of the support shaft 8 constantly biases the support shaft 8 in the direction of engagement with the locking member 11 (clockwise in FIG. 3). The hook member 7 is also provided with an operating wire 9 for rotating the hook member 7 in a direction (counterclockwise in FIG. 3) to disengage the hook member 7 from the locking member 11 against the biasing force of the spring. One end is connected. On the other hand, floor 1
A support stand 10 that abuts and supports the lower end of each of the rear legs 5 is disposed above, and a locking member 11 that locks the hook member 7 is provided on one support stand 10 (on the left side in the figure). is installed. Therefore, when the lower end surface of the rear leg 5 is brought into contact with the support base 10, the hook member 7 engages with the locking member 11, and the rear leg 5 is releasably latched to the floor 1. A first locking device 12 is constructed.

On the other hand, the seat bag 3 is attached to the rear of the seat cushion 2 at the lower portions of both sides thereof via a support shaft 13, a connecting member 14, etc., and is tiltable forward about the support shaft 13. The seat bag 3
Connecting member 14 on one side (left side in the figure)
The area covered by is the side (connecting member 14 side)
A locking pin 15 is provided that protrudes from the
A hook member 16 that can engage with the locking pin 15 is rotatably attached to the inner surface of the connecting member 14 via a support shaft 17. One end of an operating wire 18 is connected to the hook member 16 for rotating the hook portion 16 in the direction of disengaging the locking pin 15 (counterclockwise in FIG. 4). A spring 19 is attached to the connecting end of the wire 18 to the hook member 16, which always urges the hook member 16 to rotate in the direction of engagement with the locking pin 15 (clockwise in FIG. 4). So, seat bag 3
A second locking device 20 is constructed in which the hook member 16 engages with the locking pin 15 to releasably lock the seat bag 3 to the rear of the seat cushion 2 when the seat cushion 2 is in an upright state.

Further, 21 has an upper end rotatably supported on the rear end surface of the seat cushion 2 via a support member 25, and a lower end connected to the pair of left and right rear legs 5, 5 via the connecting rod 6. This is a handle for folding the rear legs in the shape of a handle, and an operating member 22 is disposed inside the handle 21 (on the seat cushion 2 side) like the trigger of a gun.
The upper part of the handle 21 is rotatably supported via a pin 23. The operating member 22 has the first and second locking devices 12 and 2 on its upper side.
The other ends of each of the operating wires 9 and 18 are connected to each other, and by rotating the operating member 22 in a direction to overlap the handle 21 and pulling the operating wires 9 and 18, the first and second locking devices 12 are locked. ,2
0 lock is released. Here, the responsiveness of the first locking device 12 to the rotation of the operating member 22 is higher than that of the second locking device 20, and the unlocking of the first locking device 12 is faster than the unlocking of the second locking device 20. It is also starting to be done first. Note that 24 is a reclining device that changes and adjusts the upright angle of the seat back 3 with respect to the seat cushion 2 by operating a handle.

Next, to explain the function and effect of the above embodiment, when folding the rear seat A in use, first grasp the rear leg folding handle 21 and the operating member 22, and then move the operating member 22 to the handle 2.
Rotate both 2 in the direction of overlapping 1.
1 and 22, the first locking device 12 is unlocked.

Thereafter, after lifting the handle 21 to the intermediate position and tilting the seat cushion 2 forward and downward, the second locking device 20 is unlocked by gripping the handle 21 and the operating member 22 even more firmly. As a result, the seat bag 3, which is tilted forward and upward on the rear of the seat cushion 2, falls forward about the support shaft 13 due to its own weight and overlaps with the seat cushion 2.

Next, the handle 21 is further lifted to place the seat cushion 2 in an inverted state, and
Push the lower end side of the handle 21 forward, and move the rear legs 5, 5 together with the handle 21 to the seat cushion 2.
Rotate it to the back side and fold it. With the above steps, the folding operation of the rear seat A is completed (see FIG. 2).

In this way, one of the first and second locking devices can be locked while holding the rear leg folding handle 21.
The folding operations of the rear seat A, such as unlocking the rear seats 2 and 20 and folding the rear legs 5 and 5, can be easily performed with a single touch.
It is possible to improve operability.

In addition, when returning the folded rear seat A as described above to the state in use, pull up the lower end of the handle 21 to return the rear legs 5, 5 to their original state, and then lower the seat cushion 2 horizontally. In this case, the seat bag 3 can be returned to the upright position, and the seat bag 3 can be returned to the upright position. In this case, the first and second locking devices 12, 20 are each automatically locked.

In the above embodiment, the second locking device is constituted by the locking pin 15 and the hook member 16, but it may also be constituted by the seat reclining device 24. In this case, the handle of the reclining device 24 may be operated using the operating wire 18.

In the above explanation, the case of the rear seat of a wagon-type vehicle has been described, but the present invention can be applied to seat structures in various other types of vehicles.
