DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the illustrated rear seat commonly referred to as a stored RR seat. 1 is a low floor 1a for foot placement and an intermediate sheet floor 1
b and the rear loading high floor surface 1c are stepped vehicle floor surfaces that are respectively connected via inclined elevation surfaces, and a link is provided on the seat floor surface 1b of the vehicle body floor surface 1 described above. The seat cushion 3 is provided so as to be able to move up and down while moving back and forth through the mechanism 2, and a seat back 4 that can be tilted forward is provided behind the seat cushion 3.

The link mechanism 2 includes a first link 2a whose ends are pivotally supported in front of the bottom of the seat cushion 3 and in front of the seat floor 1b, as in a first example shown in FIGS. A reclining center is provided at the tip of a bracket 5 erected at the rear of the seat floor 1b, comprising a rear portion of the bottom of the seat cushion 3 and a second link 2b at the rear of the seat floor 1b. The seat cushion 3 may be independently movable up and down while moving back and forth independently of the undulating operation of the seat back 4 pivotally attached with the hinge pin 6 as shown in FIGS. 3 and 4. In the second example, the seat cushion 3 is moved up and down while moving back and forth via the link mechanism 2 in conjunction with the undulating operation of the seat back 4. Has an L-shaped member 7 attached from the bottom to the rear thereof, while the seat back 4 is pivotally attached to the tip of a bracket 5 erected at the rear of the seat floor 1b with a hinge pin 6 serving as a reclining center. By pivotally connecting the upper end of the rising portion 7a at the rear of the L-shaped member 7 to the other end of the second link 2b having one end pivotally connected to the hinge pin 6, FIG.
As shown in FIG. 4, when the seat back 4 is tilted forward from a standing state in which the seat back 4 is erected on the rear portion of the seat cushion 3, the first link 2a and the second link 2b are interlocked with the forward movement as shown in FIG. The seat cushion 3 also sinks while moving forward through the link mechanism 2 consisting of the following, and the back surface of the seat back 4 becomes a receiving surface following the high loading surface 1c to form a substantially horizontal enlarged loading surface. Will be
Conversely, when the seat back 4 is raised from the lying state shown in FIG.
Is also configured to rise while retreating.

Further, in the seat cushion 3 used in the present invention, there is no gap between the front portion of the seat cushion 3 and the vehicle body floor 1 in any of the upright state and the downside down state of the seat back 4. For this purpose, a fin-shaped front hanging portion 3a uses a cushion body with a front hanging portion that is provided at the front end of the cushion body, and this is the most important point in the present invention. A gap is formed not only at the front part but also at the side part between the seat cushion 3 and the vehicle body floor 1, but the seat cushion 3 moves back and forth but does not move laterally. When there is a problem with the gap between the side portions, it may be concealed by providing a resin scuff (not shown) or the like.

[0008] With this structure, the seat back 4 is always provided to the seat in a standing state in which the seat back 4 is provided upright at the rear portion of the seat cushion 3, and the seat back 4 is required to have a wide loading surface at the rear portion. On the back is a high floor for loading 1
It is the same as a conventional vehicle seat of this type that it can be used as a substantially horizontal enlarged loading surface by being moved forward so as to be in a prone state as a receiving surface following c, but in the present invention As the seat cushion 3, a front hanging portion 3a for hiding a gap formed between the front portion of the seat cushion 3 and the vehicle body floor 1 is provided at a front end thereof. Seat back 4
In the upright state described above, the leading end of the front hanging portion 3a does not create a large gap close to the seat floor 1b so that fingers can enter each other. The front hanging part 3a is the seat floor 1
b. The upper part of the inclined standing surface connecting the lower floor 1a for foot placement and the front is covered from the front to prevent a large gap between fingers from being formed between them, so that safety is extremely high. It will be good looking.

[0009] In particular, when the seat cushion 3 is moved up and down while moving back and forth via the link mechanism 2 in conjunction with the up-and-down movement of the seat back 4, the switching operation to the two modes is easy, and When the seat cushion 3 sinks, the front hanging portion 3a moves to the upper part of the inclined surface connecting the low foot surface 1a for foot placement and the seat floor surface 1b, so that interference with the vehicle body floor surface 1 can be avoided, which is more preferable. .
