The state of (B) is held.

[0003]

[Problems to be solved by the device]

 In the configuration shown in FIG. 5, since the seat cushion 50 of the rear seat is leaned against the seat back 70 of the front seat when the luggage compartment is expanded, the seat position adjustment of this front seat is restricted. As a result, the comfort of the front seat may be adversely affected.

A technical problem of the present invention is to store the rear seat without any restriction on the seat position adjustment of the front seat when expanding the luggage compartment.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the retractable rear seat of the present invention is constructed as follows. That is, a retractable rear seat comprising a seat cushion and a seat back, wherein the seat cushion is assembled so that it can be rotated from a state of being installed on the floor to a state of leaning against a side wall of a vehicle compartment. The back is assembled so that it can be folded over to the mark of the seat cushion on the floor.

[0006]

[Action]

 When the luggage compartment is expanded in this configuration, first, the seat cushion is rotated while leaning against the side wall of the passenger compartment, and the seat back is tilted to the mark of the seat cushion. As a result, the luggage compartment is expanded without any adverse effect on the front seat side.

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the rear seat in a perspective view, and FIG. 2 also shows the internal structure of the rear seat in a perspective view. As is clear from these drawings, the rear seat comprises a pair of left and right seat cushions 10, a seat cushion side 20, a seat back 30 and a seat back side 40. It should be noted that although these members are configured symmetrically, they have substantially the same structure, and therefore the same parts will be denoted by the same reference numerals.

A seat cushion frame 12 is incorporated in the inner bottom portion of the seat cushion 10 as is apparent from FIG. Two arms 14 are fixed to the frame 12 on the side of the passenger compartment. These arms 14 are located inside the seat cushion side 20 and are rotatably connected to a side frame 22 fixed to the floor. Further, a lock member 16 is fixed to the seat cushion frame 12. The lock member 16 is adapted to be locked by being engaged with a striker 17 fixed to the floor. The seat cushion frame 12 is provided with a lock release lever 18 on the front end side of the seat cushion 10. By operating this lever 18, the lock member 16 can be unlocked with respect to the striker 17 through a wire 19. There is.

A frame cover 24 is provided inside the seat cushion side 20 to cover the side frame 22 protruding upward, thereby improving the cushioning property of the seat cushion side 20. A slit 26 for allowing movement of the arm 14 with the side frame 22 as a rotation axis is formed on a part of the pad constituting the frame cover 24 and the seat cushion side 20. .

As shown in FIG. 2, a seat back frame 32 is incorporated inside the seat back 30. The lower portion of the frame 32 is supported by a pair of hinge brackets 34 fixed to the floor so that the seat back 30 can be tilted forward. The support hole 34a of each of the hinge brackets 34 is formed in an arc shape along the rotating direction of the frame 32. Accordingly, when the seat back 30 is tilted forward, it is possible to change the rotation fulcrum of the frame 32 so that the back surface of the seat back 30 is substantially flush with the floor.

A lock member 36 is fixed to the upper portion of the seat back frame 32 on the side of the passenger compartment. On the other hand, a side striker 42 is fixed to the seat back side 40 as shown in FIG. 1 (B), and the lock member 36 is engaged with and locked to the side striker 42, so that the seat The back 30 is held so as not to fall forward. Further, a lock release knob 38 is provided on the seat back frame 32 in a state of protruding above the side upper surface of the seat back 30, and the lock member 36 can be released from the side striker 42 by operating the knob 38. Has become.

In the retractable rear seat having the above structure, when the usable rear seat of FIG. 1 (A) is stored to expand the rear luggage compartment, first, the lock release lever 18 of the seat cushion 10 is used. Is operated to unlock the lock member 16. Thereafter, the seat cushion 10 is rotated around the side frame 22 of the seat cushion side 20 as shown by the phantom line in FIG. 3, whereby the left and right seat cushions 10 are respectively moved as shown in FIG. 1 (B). Lean on both side walls of the room, and hook each seat cushion 10 by hooking a hook (not shown) on the vehicle body side to fix it.

Next, the lock release knob 38 of the seat back 30 is operated (usually a pull operation) to release the lock of the lock member 36. Therefore, the seat back 30 is tilted forward as shown by the phantom line in FIG. That is, the left and right seat backs 30 are stowed in the marks of the seat cushion 10 as shown in FIG. In this state, the seat back 30 is substantially flush with the floor surface of the luggage compartment. Further, since the seat back 30 is divided from the thick seat back side 40, the back surface of the seat back 30 is flat in the stored state of FIG. 1 (B), which makes it easy to use as a part of the luggage compartment. Become.

In order to make the rear seat usable again, the seatback 30, which is tilted to the floor side, is first rotated backwards in the reverse order of the storage operation. At this time, the locking member 36 is locked by the side striker 42 of the seat back side 40, and the seat back 30 is held in that state. Next, the hooks (not shown) are removed from the seat cushion 10 erected on both side walls of the passenger compartment, and the seat cushion 10 is returned to its original state. As a result, the lock member 16 is locked to the striker 17 on the floor, and the seat cushion 10 is held in that state.

[Effect of device]

 Thus, according to the present invention, when enlarging the luggage compartment, the seat cushion of the rear seat is swung against the side wall of the vehicle compartment, and the seat back is tilted to the mark of the seat cushion, whereby the front seat is lowered. The luggage compartment can be expanded without any restrictions such as adjusting the seat position of the seat, and the seating comfort of the front seat can be maintained well even in that state.
