[Problems to be solved by the device]

 However, there is a circumstance that this type of seat is installed near the rear wheel house H. For this reason, in order to stow the seat so that it leans against the window side of the vehicle body, conventionally, the structure is such that the seat is flipped up above the wheel house H. As shown in FIG. It had the drawback of blocking most of the area and hindering the rear view.

The present invention has been devised in view of the above circumstances, and therefore an object thereof is to make the position of the seat in the stored state as low as possible to minimize the area of the window closed by the seat. There is a vehicle foldable seat that can be used.

[0006]

[Means for Solving the Problems]

 The folding seat of the present invention includes a first hinge device that rotatably supports an edge portion of a seat cushion at a position separated from a wheel house of a vehicle by a lateral rotation shaft extending in a width direction of the vehicle body, and a first hinge device. Second hinge device that rotatably supports the hinge device of FIG. 1 on the window side of the vehicle body by a vertical rotation shaft extending in the front-rear direction of the vehicle body, and a seat cushion in a seated state removably locked to the floor of the vehicle body. It is characterized by the configuration including a lock mechanism.

[0007]

[Action]

 In order to fold the seat having the above structure, first, the lock mechanism is released and the seat cushion is rotated about the lateral rotation axis of the first hinge device, so that the seat cushion and the seat back are folded. In this state, since the lateral rotation axis is located outside the wheel house, the folded seat cushion and seat back are also located outside the wheel house. Next, the folded seat cushion and the seat back are rotated toward the window side of the vehicle body about the vertical rotation axis of the second hinge device. As a result, the folded seat cushion and the seat back stand up along the window side and the seat is stored.

In the conventional structure, the seat cushion stands up above the wheel house, whereas in the above structure, the seat cushion stands up on the floor outside the wheel house. Therefore, the upper end position of the seat cushion can be lowered by the height of the wheel house, and the window opening can be widened accordingly.

【Example】

 Hereinafter, an embodiment in which the present invention is embodied as a folding seat of the rearmost row installed in a two-box type off-road vehicle will be described with reference to FIGS. 1 to 7.

FIG. 1 shows the leftmost seat in the rearmost row. As shown in the figure, L-shaped hinge plates 12 as a whole are fixed to the left and right sides of the rear part of the seat cushion 11 by bolts 13, and the lower part of the seat back 14 is rotated by a reclining mechanism 15 on its rising end. It is movably attached.

A horizontal rotation shaft 16 extending in the width direction of the vehicle body penetrates between the hinge plates 12, and one end of the horizontal rotation shaft 16 is rotatably supported by a hinge receiving plate 17. As a result, the seat cushion 11 can rotate in the direction of the arrow b in FIG. 1 about the lateral rotation shaft 16 (the axis of which is indicated by A in FIG. 1). It is located behind the Wheelhouse H. Further, a leg 18 formed by bending a steel pipe in a U shape is rotatably attached to the front edge of the seat cushion 11, and the front edge of the seat cushion 11 is set by raising the leg 18 to an upright state. Can support

A first lock mechanism 20 that engages with a striker 19 fixed to the floor surface F of the vehicle body is provided at approximately the center of the leg 18. As shown in FIG. 4, the first lock mechanism 20 is configured by fixing a lock plate 21 having an insertion groove 21 a to a leg 18 and rotatably attaching a latch 22 via a shaft 23. Is always biased in the direction of arrow f by a torsion spring 24. Therefore, when the leg 18 is raised and the seat cushion 11 is supported by the leg 18, the latch 22 is pushed by the striker 19 and moves in the direction opposite to the arrow f direction to move the striker 19 into the insertion groove 21a. The entry is allowed, and then the torsion spring 24 returns the latch 22 to its original position and engages the striker 19. As a result, the seat cushion 11 in the seated state is locked on the floor F, and rotation in the direction of arrow b in FIG. 1 is blocked from the seated state.

The laterally rotating shaft 16 and the hinge receiving plate 17 constitute a first hinge device 25 for rotatably supporting the seat cushion 11 behind the wheel house H. The hinge device 25 is supported by a second hinge device 26 so as to be rotatable about a vertical rotation shaft (the axis of which is indicated by B in FIG. 1) extending in the front-rear direction of the vehicle body. Specifically, a hinge leg 27 is fixed to the floor F of the vehicle body on the floor F behind the wheel house H, and a vertical rotation shaft 28 is provided at the upper end thereof. As described above, the axis B of the vertical rotation shaft 28 extends in the front-rear direction of the vehicle body, and the hinge receiving plate 17 of the first hinge device 25 is rotatably attached thereto. .. As a result, the first hinge device 25 and thus the seat cushion 11 can be rotated about the axis B to be in a standing state along the window side.

On the other hand, a second lock mechanism 29 is provided on the opposite side (right side) of the seat cushion 11 from the second hinge device 26. As shown in FIG. 6, the second lock mechanism 29 rotatably mounts a lock plate 30 having an insertion groove 30a on the right side portion of the seat cushion 11 with a stepped bolt 31 and a latch 32 to the lock plate 30. The latch 32 is rotatably provided via a shaft 33, and the latch 32 is constantly biased in the direction of arrow g by a torsion spring 34. Therefore, when the seat cushion 11 is set in the seated state, the striker 35 fixed to the floor F and the latch 32 engage with each other, and the seat cushion 11 can be engaged with and disengaged from the floor F, similarly to the first lock mechanism 20. Locked in.

A striker 36 is fixed to the floor F behind the second hinge device 26 and located on the axis B of the vertical rotation shaft 28, as shown in FIG. A lock claw 37 is attached to a side portion of the seat cushion 11 at a position corresponding to the striker 36 when the seat cushion 11 is folded and overlapped with the seat back 14 shown in FIG. As shown in FIG. 5, the lock claw 37 is rotatably supported by a rotary shaft 39 attached to a holder 38, and is constantly biased in the direction of arrow h by a torsion coil spring 40. The tip of the claw 37 is formed into an inclined surface so that the lock claw 37 can rotate when it comes into contact with the striker 36.

Next, a procedure for storing the sheet having the above configuration will be described.

It is assumed that the seat is in a seated state as shown in FIG. In this state, the first lock mechanism 20 provided on the leg 18 is engaged with the striker 19, the second lock mechanism 29 is engaged with the striker 35, and the seat cushion 11 is locked to the floor F. It Therefore, even if the vehicle vibrates violently, the seat cushion 11 is not likely to be flipped up.

To fold the seat, first, the lever 15 a of the reclining mechanism 15 is released, and the seat back 14 is tilted forward (in the direction of arrow a) to be folded over the seat cushion 11. Next, the latch 22 of the first lock mechanism 20 is held and rotated, the engagement between the striker 19 and the latch 22 is released, and the front edge portion of the seat cushion 11 is lifted. Then, the seat cushion 11 rotates about the lateral rotation shaft 16 of the first hinge device 25 (in the direction of arrow b in FIG. 1) and flips backward. When completely turned upside down, the lock claw 37 engages with the striker 36 as shown in FIG. 2, and the seat cushion 11 and the seat back 14 in the overlapped state move from the seated position to the rear of the wheel house H. It becomes a saved form.

Next, the leg 18 is rotated in the direction of the arrow c in FIG. 2 to be housed in the storage recess 11 a of the seat cushion 11, and the latch 32 of the second lock mechanism 29 is held by a hand to rotate it. The latch 32 and the striker 35 are disengaged by moving the seat cushion 11, and then the right edge portion (the side opposite to the window side) of the seat cushion 11 is lifted. Then, the seat cushion 11 and the seat back 14 in the overlapped state are rotated about the vertical rotation shaft 28 of the second hinge device 26 this time (in the direction of arrow d in FIG. 2), and as shown in FIG. Stand up so that you can lean against the window side of the car body. Then, the lock plate 30 of the second lock mechanism 29 is rotated in the direction of arrow e in FIG. 3 to retract it, and the hook 41a of the fixed belt 41 is hooked on the striker 42 of the vehicle body, whereby the seat storing operation is completed.

In this stored state, the seat cushion 11 and the seat back 14 in the overlapped state are leaned against the window W on the floor F behind the wheel house H as shown in FIG. Therefore, as compared with the conventional structure in which the seat is leaned above the wheel house H and positioned at a high place as shown in FIG. 8, the area in which the window W is blocked by the seat is reduced and the rear view is obstructed. This can be suppressed as much as possible.

In the above embodiment, the first and second lock mechanisms are provided so that the seat cushion can be locked more reliably. However, in the present invention, at least one lock mechanism is provided. Just do it. Besides, the present invention is not limited to the embodiments described above and shown in the drawings. For example, the lateral rotation shaft of the first hinge device rotatably supports the front edge side of the seat cushion. For example, various modifications can be made without departing from the scope of the invention.

[0022]

[Effect of the device]

 As described above, according to the folding seat of the present invention, the position of the seat in the retracted state is lowered, the area of the window closed by the seat can be reduced, and the view from the window can be sufficiently secured. It has an excellent effect.
