に引き出される。In FIG. 3, the frame C of the vehicle seat is shown.
The case where the direction is changed from the state of the one-dot chain line parallel to the wall surface 1 to the position of the solid line perpendicular to the wall surface 1 will be described. The side of the frame C close to the carriage 4 is perpendicular to the wall surface 1 from the state of the one-dot chain line. When pulled in the direction, the wheels 3 roll and the dolly 4 is pulled out in a direction perpendicular to the wall surface 1.

に向くことになる。Prior to passing through this state, the first pivot arm 18 pivots about the pivot point e, so that the pivot point d at the tip of the pivot arm reaches d 3 and the telescopic arm is extended. Since 17 is in the extended state, the center of rotation of the frame C is separated from the wall surface 1. Moreover, the second rotating arm 19 rotates about g 3 moved in the positional relationship between the pivot point g and the pivot point f,
Since the pivot point f is moved to f 3 , the frame C is oriented at a right angle to the connecting arm 16, that is, in the direction of 45 degrees with respect to the wall surface 1.

枠体Ｃの方向を換えることが可能になる。As a result, one of the left and right rear ends of the frame C moves linearly in parallel with the wall surface 1 and the other rear end of the frame C linearly moves in a direction perpendicular to the wall surface 1. It is possible to change the direction of the frame C halfway without hitting the seat A and the backrest B.

It is pivotally attached to a base 8 fixed to the floor surface 7 along with, and these are the same as those in the first embodiment.

向に引き出される。A horizontal guide groove 22 is formed on the wall surface 1, and a slide piece 23 that slides in the guide groove 22 is hinged to the frame C on the side opposite to the downward extension 2. . Therefore, when the seat A and the backrest B are parallel to the wall surface 1, the upper ends of the backrest B on the base 8 side can be pulled out in a direction perpendicular to the wall surface 1 so that the arms 5 and 6 are horizontal. Therefore, the carriage 4 is pulled out in a direction perpendicular to the wall surface 1.

From i 1 corresponding to the position to i 2 corresponding to h 2 ,
i 3 corresponding to h 3 is reached.

がない。As described above, since the locus h of the attachment point and the locus i of the hinge attachment point are straight lines, when the seat portion A and the backrest B are turned, the seat portion A and the backrest B are different from each other. The backrest D and the wall surface 1 do not come into contact with each other and the direction cannot be changed.

When the seat portion A and the backrest B of the third embodiment are pulled out at a right angle to the wall surface 1, two frame bodies C and C'which are back to back of the connecting plate 30 fixed to the carriage 4 are provided. The hinges 31 are rotatably attached to the left and right sides.

がぶつかり合うことがない。Therefore, the two frames C and C'attached to the connecting plate 30 by the hinges 31 rotate in opposite directions when the carriage 4 moves away from or approaches the wall surface 1. Moreover, in the same manner as the locus h of the attachment points and the locus i of the hinge points in the third embodiment are straight lines, also in this embodiment, since the loci are straight lines, the two seat portions A and the backrest B are provided.
Do not collide with each other.

It can be rotated in the direction or in the parallel direction, and the direction changing mechanism can be simplified.

ようにして、９０度方向転換できるものである。As described above, according to the present invention, a romance sheet-like chair installed close to a wall surface has at least one of the left and right sides near the wall surface at least near the wall surface. Alternatively, it is possible to change the direction by 90 degrees by drawing a linear locus in the direction perpendicular to this.

置できる椅子の数を増やすことができる。Therefore, a space is provided between the wall surface and the wall for the protruding portion even outside the linear locus as in the case of turning around one point, or in line with the back-to-back parallel arrangement system. Since it is possible to switch to the serial arrangement system, it is not necessary to provide a gap or the like for avoiding collision with adjacent chairs, waste of space can be eliminated, and the number of chairs that can be arranged in a predetermined space can be increased.

るものである。Further, unlike a conventional chair for a vehicle capable of changing direction, it is not necessary to tilt the backrest forward when changing direction, so that the changing operation is simple and, in particular, changing direction is performed by power. In this case, there is an effect that a mechanism for an extra operation is unnecessary and the mechanism can be simplified.
