The container 7 is received and supported by the bracket 8 in a state where the position of the container 7 is regulated by the side portion of the holding frame 4. The container 7 is detachably housed and held in the holding frame 4 and the bracket 8, but may be fixed. The above points are the same as or similar to the conventional one.
In this embodiment, the seat cushion 2 is connected to the holding frame 4 via the parallel link 10, and is disengaged from the holding frame 4 via the latch mechanism 20. Next, the main part will be described in detail.

(Main Structure) The holding frames 4 are arranged in pairs on both sides, the upper part is integrated with a frame member 9 and the auxiliary aggregate 4a interposed between the holding frame 4 and the frame member 9; It has brackets 8 and the like, which secure the strength. A receiving portion 9a is provided on the rear side of the frame member 9. The receiving portion 9a receives and holds a corresponding portion of the cushion frame 2a. Cushion frame 2a
The parallel link 10 and the tension spring member 13 are interposed between the frame member 9. That is, the cushion frame 2
A pair of brackets 11 is provided on both sides of the frame member 9 and on both sides of the frame member 9 in the left and right directions (four on one side, a total of eight). A link 10 is connected to the upper and lower brackets 11 with both ends pivotally supported by pins 12. For this reason, the seat cushion 2 is connected to the frame member 9 by the front and rear and left and right links 10, and from the normal state of the seat holding mode of FIG. 1 to the front shown in FIG. Be moved. This forward movement moves along a trajectory in which the link 10 is rotated about the lower pin 12 as a fulcrum, and the amount of movement is a dimension corresponding to the link length. In this example, the seat cushion 2 is held at the front side of the frame member 9 in a state of being translated as shown in FIG. 2, and the rear link 10 also hits the corresponding portion of the frame member 9 and is restricted from rotating. On the other hand, the tension spring member 1
Reference numeral 3 denotes a normal state shown in FIG. are doing.

The seat cushion 2 is locked to the frame member 9 by the latch mechanism 20 in the normal state shown in FIG. As shown in the enlarged view of FIG. 3, the latch mechanism 20 is provided on the rear side of the frame member 9 and is fixed to a rear end surface of the frame member 9. Half 21
And a movable half 22 having a substantially inverted L-shape rotatably mounted via a pin 23 to the movable half 22 and biasing the movable half 22 toward the fixed half 21 with both ends locked to the two halves 21 and 22. Biasing spring 24 and a release wire 26 that turns the movable half 22 away from the fixed half 21 to release the lock.

One end 26a is locked to a reverse L intermediate portion of the movable half 22,
The other end extends to the front of the frame member 9, that is, to the lower front portion of the seat cushion 2, and the operation knob 27 is connected thereto.

(Operation) The above-described latch mechanism 20 is configured to engage and disengage the striker 25 projecting from the rear side of the cushion frame 2a between the two halves 21, 22. The body is locked between the bodies 21 and 22. The seat cushion 2 is connected to the holding frame 4 (the frame member 9) by the parallel link 10, and the position of the seat cushion 2 is regulated by the locking force of the latch mechanism 20 with respect to the striker 25. Accordingly, when the occupant pulls the operation knob 27 disposed on the lower front side of the seat cushion 2, the movable half 22 is rotated and inclined via the release wire 26 as shown in FIG. , A gap is formed between the fixed half 21 and the striker 25. At the time of unlocking, the tension spring 13 acts so that the seat cushion 2 automatically floats slightly above the holding frame 4 (frame member 9). For this reason, the seat cushion 2
Is the lower pin 12 of the parallel link 10
Floats slightly toward the front with the center at the center. The seat cushion 2 is moved forward in accordance with the rotation locus of the parallel link 10 while being lifted on the frame member 9 by being manually pushed forward from this state. As a result, the container 7 in the holding frame 4 is largely exposed at the place where the seat cushion 2 was placed as shown in FIG. 2, so that articles can be taken in and out of the container 7.

When the seat cushion 2 moves forward, the tension spring member 13 elastically supports the seat cushion 12 with an appropriate elasticity from a stage where the seat cushion 2 has exceeded the highest position. At the final stage where the seat cushion 2 has moved forward, the parallel link 1
0 abuts on the corresponding portion of the frame member 9 and is held.

When the seat cushion 2 is moved forward in FIG. 2, the seat cushion 2 is substantially parallel to the floor surface F, so that an article W or the like can be placed on the upper surface of the seat cushion 2.
For example, an article or the like taken out of the container 7 can be placed, and the function as a tray can also be used. The seat cushion 2 is returned to the normal state shown in FIG. 1 by being pushed in the rearward direction.
When the striker 25 is pushed by the striker 25, the striker 25 is automatically opened and the striker 25 can be received. The click sound at this time confirms that the lock has been performed again.

The present invention is not limited to the above-described embodiment as long as it satisfies the requirements defined in the claims. For example, the form of the holding frame 4 may be changed, or the holding frame 4 itself may be omitted as in the related art shown in FIG. In a mode in which the holding frame 4 is omitted, the frame member 9 on the fixed side becomes the holding frame of the present invention. The shape of the container 7, the presence or absence of the lid, and the like are arbitrary, and can be designed as needed.

[0016]

As described above, the vehicular seat with the storage compartment of the present invention moves the seat cushion substantially parallel forward through the parallel link when articles are put in and out of the container. As compared with the conventional structure described above, the sense of incongruity can be eliminated to some extent, and the seat cushion that has been moved forward can also be used as a tray to improve usability and convenience.
