TECHNICAL FIELD OF THE INVENTION
The present invention provides a seat back in a reclined position so as to abut on the upper surface of a rear cushion of the front and rear cushions when the seat is not used, and the front back is positioned near the front of the seat back in the reclined position. The present invention relates to a foldable seat for an automobile in which a seat can be placed in a "folded state" by positioning a cushion.
[0002]
[Prior art]
A conventional foldable seat for an automobile is disclosed in Japanese Utility Model Publication No. 5-45557.
[0003]
According to the publication, a seat is provided on a floor panel of a vehicle body of an automobile, and the seat is supported by the floor panel; and a seat cushion is supported on the seat base and extends substantially horizontally. The seat cushion includes a seat back extending upward from the rear end side of the seat cushion, the upper side of the seat cushion extending forward and downward, and being rotatable backward.
[0004]
In the above case, the seat is in a “seatable state” with the seated person facing forward.
[0005]
Further, the seat cushion is constituted by front, rear and front and rear cushions, and the front cushion is allowed to move forward and backward, and the upper part of the seat back is formed by the front cushion. By rotating the seat back forward until it enters the occupied space, the seat back can be placed in a lying position that extends substantially horizontally, and in this case, the front surface of the seat back is positioned above the rear cushion in the lying position. At the same time, the seat table is brought into contact with and supported by the upper surface of the front part of the seat table.
[0006]
In addition, as described above, the front cushion, which is positioned so that the front surface of the seat back is positioned above the rear cushion in the reclined position, is supported by being in contact with the front upper surface of the seat table, and moved forward, When the seat is positioned near the front of the seat back in the reclined position, the seat is in a compact folded state.
[0007]
When the seat is in the “folded state” as described above, the upper surface of the seat back in the reclined position is a flat surface extending substantially horizontally, and this can be used as a loading surface.
[0008]
[Problems to be solved by the invention]
By the way, the above-mentioned conventional technology has the following problems.
[0009]
That is, the front surface of the seat back extends substantially linearly when viewed from the side, while, in the "folded state" of the seat, the front surface of the seat back is positioned above the rear cushion in the reclined position. As shown in FIGS. 1 and 2 of the above-mentioned publication, the upper surface of the rear cushion and the upper surface of the front portion of the seat table have substantially the same height, as shown in FIGS. It is said.
[0010]
For this reason, as shown in FIG. 2 of the publication, when the seat is in a “seatable state” and the front cushion is supported on the front upper surface of the seat base, If the thickness of the cushion in the vertical direction is large, the level difference between the upper surfaces of the front and rear cushions is correspondingly increased, and there is a possibility that good sitting comfort with respect to the seat cushion may not be obtained.
[0011]
Therefore, in order to reduce the step, the thickness of the front cushion needs to be suppressed to some extent, but for this reason, it may be difficult to obtain a good cushioning effect on the front cushion during sitting. .
[0012]
Further, when the front cushion is located near the front of the seat back in the reclining position in the above-mentioned "folded state" of the seat, in the conventional technique, the front cushion is positioned higher than the upper surface of the seat back in the reclining position. The upper part projects greatly upward.
[0013]
For this reason, there is a problem that it is not possible to obtain a flat and wider loading surface connected to the front from the upper surface of the seat back in the lying posture.
[0014]
The present invention has been made in view of the above circumstances, and when the seat is in a "folded state", the front surface of the seat back is positioned above the rear cushion in the reclined position, and the seat base is placed. When the front cushion which is brought into contact with the upper surface of the front part and moves forward is positioned in front of the seat back in the reclined position as described above, the thickness of the front cushion can be made sufficiently large. An object of the present invention is to provide a good buffering effect in this manner.
[0015]
It is another object of the present invention to provide a flat and wide loading surface when the sheet is in the "folded state".
[0016]
[Means for Solving the Problems]
