DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. The drawing shows a case in which the present invention is applied to an automobile seat provided in a third row, in which a seat 1 including a seat cushion 1a and a seat back 1b is directed toward a seating surface of the seat cushion 1a. The seat 1 is stored in a storage recess 2 formed on the vehicle body floor 20 behind the seat via a link member 10 connecting the rear portion of the seat cushion 1a and the vehicle body floor 20 with the seat 1a folded down. However, a spring 4 is provided at the floor side connecting portion of the link member 10 so as to resiliently open the opening angle α between the link member 10 and the bottom of the storage recess 2 in a direction in which the link 4 is constantly expanded. The direction in which the opening angle β between the link member 10 and the lateral surface of the seat cushion 1a is constantly expanded at the seat-side connecting portion of the link member 10. When the laminated sheet 1 stored in the storage recess 2 is raised from the storage state to the use state, as described later, The above-mentioned spring 3,
4, it is possible to extremely easily perform the operation of pulling up the superposed sheet 1 that has been pulled upward by the action of the elastic force of 4. Also, when the superposed sheet 1 is stored in the storage recess 2, By the action of the resilient forces of the springs 3 and 4, a sharp drop is prevented and safe operation is possible.

In the drawing, the spring 3 is provided at the seat-side connecting portion of the link member 10 and the springs 4 are provided at both of the floor-side connecting portions. 3 or the spring 4 is provided only on the floor-side connecting portion, the point is that the superposed sheet 1 stored in the storage recess 2 can be easily pulled out with a small force by utilizing the action of the spring. In addition to the seat cushion 1
When storing the superimposed seat 1 in which the seat back 1b is turned down toward the seating surface a and stored in the storage recess 2, it is sufficient that the superimposed seat 1 can be gradually stored while being supported by a spring so as to eliminate a sudden drop. The springs 3 and 4 for expanding the opening angle described above use a spiral spring, and the spring 4 uses a coil spring, as shown in FIG. Although an upward force is always applied to the seat 1, any kind of spring can be used as long as it has the same effect.

The link member 10 is formed of an L-shaped member, one end of which is rotatably connected to the rear of the seat cushion 1a via a hinge 10a, and the other end of which is hinged forward of the bottom of the storage recess 2. The seat 1 is formed as a seat by rotating the link member 10 around the hinge 10b, and the seat is stored in the storage recess 2. It is configured to take.

The link member 10 is formed integrally with a U-shaped frame when viewed in a plan view.
As described above, the link member is a rod-shaped body as in the related art, and is simply formed by the rear portion of the lower surface of the seat cushion 1a and the storage recess 2.
Is not connected to the front portion of the bottom surface of the sheet, so that the sheet can be lifted in a stable state without causing rotation or unevenness when the overlapping sheet 1 moves.

Further, between the link member 10 and the seat cushion 1a, a resilient member 5 for holding the superposed sheet 1 stored in the storage recess 2 in a substantially horizontal state is stretched. Spring member 5 and springs 3 and 4 described above
Acts so as to balance the load on the sheet, so that the overlapped sheet 1 is always easily kept in a horizontal state. The resilient member 5
For example, a damper or a coil spring utilizing fluid pressure can be used.

In FIG. 1, reference numeral 6 denotes a front leg provided on the front lower surface of the seat cushion 1a. The front leg is engaged with a hook 6a provided on a vehicle body floor 20 when used as a seat. The seat cushion 1a is configured to be folded into the seat cushion 1a so as not to be in the way.

The link member 1 constructed as described above
0 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 also has the link member 10 having a seat-side connection portion and a floor-side connection portion. Since one or both of them is provided with a spring for widening the opening angle, as shown in FIG.
4, an upward force is always applied to the sheet 1 by the elastic force of 4. Therefore, when the superimposed sheet 1 is pulled up to move from the stored state to the use state, it can be easily applied with a small force. The seat 1 can be lifted, and the lifting operation can be performed very easily. Also, when the seat 1 is moved to the storage recess 2, a sudden drop is prevented by the action of the resilient force of the springs 3 and 4, so that the operation can be performed extremely safely.

When a resilient member 5 for holding the seat 1 in a horizontal state is stretched between the link member 10 and the seat cushion 1a, the resilient member 5 and the springs 3, 4 are connected. Since the sheet 1 acts so as to balance the load of the sheet, the sheet 1 is always kept in a horizontal state, and excellent handling properties can be exhibited, which is more preferable.

When the seat 1 is stored, the seat back 1b is folded toward the seat cushion 1a and the fixing of the front leg 6 is released. In this state, the link member 10 is rotated rearward into the storage recess 2. On the other hand, the operation of taking out the sheet 1 can be performed by simply performing the reverse of the above operation, and all operations can be performed by a simple operation.

[0015]

As is apparent from the above description, according to the present invention, it is possible to easily pull out the superimposed sheet stored in the storage recess with a small force, and furthermore, to seat the seat back toward the seat surface of the seat cushion. Even when the folded-down superposed sheet is stored in the storage recess formed on the vehicle body floor, there is an advantage that it can be safely operated without a sudden drop. Therefore, the present invention greatly contributes to the development of industry as an automobile seat storage structure that has eliminated the conventional problems.
