DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
The drawings show the case where the present invention is applied to an automobile seat provided in the third row, in which the seat 1 comprising the seat cushion 1a and the seat back 1b is directed to the seating surface of the seat cushion 1a. The stacking sheet 1 is placed in an overlaid state, and the stacking sheet 1 is slanted into a storage recess 2 formed in the vehicle body floor 20 behind the seat via a link member 10 that connects the rear portion of the seat cushion 1a and the vehicle body floor 20. The floor-side connecting portion of the link member 10 described above is stored in the downward direction so that the opening angle α between the link member 10 and the bottom of the storage recess 2 is always expanded. An elastic spring 4 is provided, and the opening angle between the link member 10 and the lateral surface of the seat cushion 1a is provided at the seat side connecting portion of the link member 10. A spring 3 is provided to repel β in a direction in which it is always expanded. With this structure, the overlapping sheet 1 stored in the storage recess 2 is used from the stored state to the used state as will be described later. In the case of pulling up, the stacking sheet 1 that has been pulled upward by the action of the elastic force of the springs 3 and 4 can be pulled up very easily. Even when the laminated sheet 1 is stored in the storage recess 2, the springs 3 and 4 can be operated safely by preventing the sudden drop due to the elastic force.
[0007]
Incidentally, the spring 3 and 4 for the angle expanding open noted previously, by way of illustration, the spring 3 is a spiral spring, the spring 4 has a one using a coil spring, each imparting elastic force of the direction of the arrow However, although an upward force is always applied to the seat 1, any type of spring can be used as long as it has the same effect.
[0008]
The link member 10 is an L-shaped member as viewed from the side, and has one end rotatably connected to the rear portion of the seat cushion 1a via a hinge 10a and the other end hinged to the front of the bottom of the storage recess 2. The link member 10 rotates about the hinge 10b and the seat 1 forms a seat, and the seat 2 is stored in the storage recess 2. It is configured to adopt.
[0009]
The link member 10 is formed integrally with a U-shaped frame when viewed in plan, and thus the link member is a rod-like body as in the prior art, and is simply a seat cushion 1a. Since the rear surface of the lower surface and the front portion of the bottom surface of the storage recess 2 are not connected to each other, the sheet can be lifted in a stable state without causing rotation or unevenness when the overlapping sheet 1 is moved. .
[0010]
Further, a resilient member 5 is held between the link member 10 and the seat cushion 1a to hold the overlapping sheet 1 stored in the storage recess 2 in a substantially horizontal state. The above-described springs 3 and 4 act so as to balance the load on the sheet, so that the superposed sheet 1 is always easily held in a horizontal state. As the elastic member 5, a damper or a coil spring using fluid pressure can be used.
[0011]
In the figure, reference numeral 6 denotes a front leg provided at the front portion of the lower surface of the seat cushion 1a. When used as a seat, the front leg is engaged with and fixed to a hook 6a provided on the vehicle body floor 20, and does not get in the way when the seat is stored. The seat cushion 1a is configured to be folded.
[0012]
In this structure, the link member 10 not only has one end rotatably connected to the rear portion of the seat cushion 1a and the other end rotatably connected to the storage recess 2, but the link member 10 since the bi-direction of the sheet-side connecting portion and the floor-side connecting portion, it is assumed to have arranged the spring 3 and 4 for the angle expanding opening each, as shown in FIG. 3, the resilient spring 3,4 Accordingly, an upward force is always applied to the sheet 1 due to the force. Therefore, when the stacked sheet 1 is pulled up to move obliquely from the stored state to the used state, the sheet 1 can be easily and easily moved with a small force. Can be lifted, and the lifting operation can be performed very easily. In addition, when the seat 1 is moved to the storage recess 2, a sudden drop is prevented by the action of the elastic force of the springs 3 and 4, so that it can be operated extremely safely.
[0013]
Further, Ri stretched the elastic member 5 for holding the sheet 1 in a horizontal state between the link member 10 and the seat cushion 1a tare, the load of the spring 3, 4 and the elastic member 5 is sheet to act to balance against the sheet 1 is that Do and to always be exhibited handling properties superior will be held in a horizontal state.
[0014]
The seat 1 is retracted by folding the seat back 1b to the seat cushion 1a side and releasing the front leg 6 and rotating the link member 10 rearward in this state to move into the housing recess 2. On the other hand, the operation of taking out the sheet 1 can be performed by a simple operation only by performing an operation reverse to the above.
[0015]
【The invention's effect】
As is clear from the above description, the present invention can easily pull out the overlapping sheets stored in the storage recesses with a small force, and also overlaps the seat back on the seat cushion seat surface. There is an advantage that it can be safely operated without a sudden drop when the laminated sheet is stored in the storage recess formed in the vehicle body floor.
Therefore, the present invention contributes greatly to the development of the industry as an automotive seat storage structure that eliminates the conventional problems.
