[0051] Similarly, the upper end 71a of the second plate 71 of the second interlock pin plate 55 that has been rotated rotates the first plate 70 connected by the sixth shaft support portion 73 around the fifth shaft support portion 67. The one end 70a projecting from the first plate 70 pushes up the front FR portion of the first tip uplock plate 53 from the second shaft support portion 63, so that the first tip up lock plate 53 is in the second position. The stopper rod 61 moves freely on the long hole 47 because it rotates clockwise around the shaft support 63 and the position force that the claw 53a of the first tip uplock plate 53 protrudes into the long hole 47 is also released. It becomes. Therefore, the seat cushion 21 can be moved to a substantially horizontal position.

Next, the operation of this embodiment will be described.

[0053] When the seat cushions of both seat bodies are in the tip-up position, the interlock means is held in a state in which it cannot be re-engaged with the slide device, so that the seat cushion is substantially horizontal at a position other than the seating position. It will not be possible to return to the correct position, which will increase safety. [0054] Since both the front and rear slide lock means 34 and the interlock means 35 of the passenger seat 2 can be released by the push plate 36 of the second rear seat 4, the second rear seat 4 is used for the assistant. By simply pushing the seat 2 backward force, the push plate 36 releases the front / rear slide locking means 34 and the interlocking means 35, and the force of pushing the second rear seat 4 to the front FR allows the passenger seat 2 to move to the front FR. This is possible with a simple operation.

[0055] In the slide device, the front seat body and the rear seat body are in the second mode region and the fourth mode region, which are substantially horizontal positions separated from each other in the front-rear direction. The first mode region and the fifth mode region and the second mode region and the fourth mode are the foremost and last positions where the front seat body and the rear seat body are in close contact with each other. Since the interlock means cannot be engaged in the third mode area between the areas, the seat cushion is used in the first, third, and fifth mode areas where the occupant does not sit on the seat cushion. Since it cannot be returned to a nearly horizontal position, safety will be increased more reliably.

[0056] The passenger seat 2 and the second rear seat 4 both move the seat backs 20, 22 to a substantially upright position by operating means (not shown) and tip up the seat cushions 19, 21 and Because the rear seat 4 allows the passenger seat 2 to be moved to the front FR, the passenger seat 2 can be moved to the front FR only by operating the second rear seat 4 after a predetermined operation. it can. In other words, the operability when the passenger seat 2 and the second rear seat 4 are gathered together at one power point is remarkably improved.

[0057] Further, the tip-up mechanisms 37, 38 of the seat cushions 19, 21 move the tip-up brackets 40, 41 of the seat cushions 19, 21 by moving the seat backs 20, 22 to an upright position where they are almost upright. Tip-up releasing means 48, 49 for releasing, first coiled springs 50, 51 for tipping up the seat cushions 19, 21 in a state where tip-up is possible by the tip-up releasing means 48, 49, and the tip Since the seat cushions 19 and 21 that have moved to the up position are composed of the first and second tip up lock plates 52 and 53 that hold the seat cushions in the up position, the seat backs 20 and 22 are in an upright position where they are almost upright. By moving, the first and second tip-up lock plates 52, 53 of the seat cushions 19, 21 held in a substantially horizontal position are released, and the first coin springs 50, 51 release the force S. Seat cushion 19, 21 is moved up, and the seat cushions 19 and 21 that have been chipped up can be held in that position by the first and second tip-up lock plates 52 and 53. Further, since the first and second interlock pin plates 54 and 55 that can release the first and second chip-up lock plates 52 and 53 are provided, the seat cushions 19 and 21 can be returned to the original positions again.

[0058] Furthermore, the release bracket 8 6 of the passenger seat 2 is pushed by the push plate 36 of the second rear seat 4 to release the stopper lock pin 87 and the interlock means 35 of the front and rear slide lock means 34. Therefore, the passenger's seat 2 can be moved by being pushed by the second rear seat 4.

[0059] Furthermore, the foremost side portion 36a of the push plate 36 of the second rear seat 4 is in a position protruding to the front FR from the seat cushion 21 in the tip-up state of the second rear seat 4, so that the second When the rear seat 4 is moved to the front FR, the moving means 85 of the passenger seat 2 can always be pressed, and the assistant seat 2 can be reliably moved to the front FR together with the second rear seat 4.

In the above embodiment, the front seat body is described as the passenger seat 2 and the rear seat body is described as the second rear seat 4 as an example. However, the present invention is not limited to this. The main seat may be the driver's seat 1, the rear seat itself may be the first rear seat 3

[0061] In addition to the above, the present invention can be implemented in various other modes by making appropriate modifications that are not limited to the description of the embodiments of the invention described above.
