[Problems to be solved by the device]

 By the way, if a seat (rear seat) is arranged behind the seat and the seat is occupant in the rear seat and the seat is inadvertently erected, the seat is seated on the second leg portion 5 of the seat. Your legs may get caught. Therefore, the purpose of the present invention is to address such a problem.

[0005]

[Means for Solving the Problems]

 The present invention relates to a foldable seat, and a seat cushion and a first leg portion having an upper end portion fixed to a front portion of a lower surface of the seat cushion and a lower end portion rotatably mounted in a front-rear direction on a floor. And a second leg portion whose lower end portion is rotatably attached to the floor in the front-rear direction and receives the rear portion of the lower surface of the seat cushion at the upper end portion when standing up, the second leg portion and the A locking means is provided between the seat cushions for releasably locking both of them, and the first leg portion and the second leg portion are connected to each other via a link mechanism to interlock with each other. It is characterized by being set up.

[0006]

[Operation and effect of the device]

 In the foldable seat having such a structure, when the seat cushion is locked to the second leg portion by the locking means, the seat cushion is held in a horizontal state and can be seated. In this state, if the locking of the seat cushion with respect to the second leg portion by the locking means is released, the first leg portion can be rotated forward, and the seat cushion can be folded forward by lying down. You can In this case, the second leg rotates in conjunction with the first leg and falls down.

In this state, when the seat cushion is rotated to raise the seat, the second leg is rotated in association with the first leg to stand up and the rear portion of the seat cushion is rotated. The seat cushion is locked to the second leg portion by the action of the lock mechanism and the seat cushion is held horizontally. In this case, if the occupant's foot of the rear seat is located on the second leg, the second leg lifts the occupant's foot, and the occupant feels his or her foot. Withdraw from the second leg and do not cause any problems.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a folding seat according to one embodiment of the present invention. Since the seat is equipped with a seat back, the seat cushion 11, the seat back 12, the pair of left and right front leg portions 13a and 13b, the rear leg portion 14, the link 15, and the latch 16a constituting the locking means. , Striker 16b.

The seat back 12 is assembled so that it can be folded forward at the rear end of the seat cushion 11, and the front lower surface of the seat cushion 11 has front and rear legs 13a, 13b. The upper end is fixed. The front leg portions 13a and 13b correspond to the first leg portion of the present invention, and the lower end portions of the leg portions 13a and 13b are rotatably assembled forward on the flat portion f1 of the floor. . The floor is provided with a U-shaped first recess f2 that opens upward in the flat part f1 and a rectangular second recess f3 that opens laterally, and each front leg 13a, 13b. Is assembled in front of the first recess f2.

The rear leg portion 14 has a substantially U shape similar to the first recess f2, and is attached to the first recess f2 so as to be rotatable in the front-rear direction at both ends thereof. . In the upright state, the rear leg portion 14 is positioned on the rear portion of the lower surface of the seat cushion 11 which is upright and in a horizontal state, and the latch 16a is attached to one of the central portions facing each other, and the other. The striker 16b is assembled.

When the link 15 is accommodated in the second recess f3, the front end is connected to the front leg 13a via the first arm 17a, and the rear end is connected to the rear leg via the second arm 17b. It is connected to the lower end of the portion 14. The link 15 is rotatably connected to each arm 17a, 17b, and each arm 17a, 17b is integrally rotatably connected to each leg 13a, 14.

The folding seat having such a structure can be folded forward as shown in FIG. 1, and in this state, when the seat cushion 11 is rotated backward, the front leg portions 13a and 13b are erected. The rear leg portion 14 stands up in association with the front leg portions 13a and 13b by the action of the link 15. Therefore, the rear leg portion 14 stands up at the same time as the front leg portions 13a and 13b, shifts to a horizontal state, receives the rear portion of the lower surface of the seat cushion 11, and latches the seat cushion 11 side. 16a and the striker 16b on the rear leg portion 14 side engage with each other to lock the seat cushion 11 and the rear leg portion 14 to each other. As a result, the seat cushion 11 is securely held in the horizontal state, and can be seated by raising the seat back 12.

By the way, even if the seated person's foot of the rear seat is positioned on the rear leg part 14 when the seat is erected, the rear side leg 14 lifts the seated person's foot, so By noticing this, the foot is retracted from the rear leg portion 14, and no problem arises in the subsequent standing operation of the seat.

In the present embodiment, the seat provided with the seat back 12 has been described as an example, but the present invention can be applied to a foldable seat without a seat back. Of course.
