Is something that can

When the device is installed so that the seat can be slid on the pedestal, the seat can be retracted to secure a sufficient space with the front seat at the time of boarding, and the entire seat can be pushed out to the outside of the passenger compartment. You can easily sit in your seat and stand up easily.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the drawings which are an example of an embodiment. A pedestal bottom plate 4 is attached to a floor surface 3 of a passenger compartment 2 of a one-box car 1, and a pivot 5 is erected at its center. A pedestal is provided by pivotally supporting a swivel base plate 6 rotatable around a pivot, and rail frames 8 and 8 which are inward U-shaped rail portions 7 and 7 are attached on both side edges of the swivel base plate 6 of the base. The plates 9 and 9 are connected and attached. Reference numeral 10 denotes a swivel auxiliary support wheel attached to the lower surface of the swivel base plate 6, and in this embodiment, the swivel auxiliary support wheels are arranged at four positions to roll on the base plate 4.

A slide driving support frame 12 having rollers 11 projecting from the side faces at the front and rear ends is provided, and each roller 11 is engaged with the U-shaped rail portions 7, 7 of the rail frames 8, 8 to form the rail frame 8, While being slidable back and forth along 8,
A motive drive support frame 13 is integrally supported around the center of the slide drive support frame 12, and the support shafts 14 and 15 are passed around the lower part of the slide support frame 12 by changing its position up and down as shown in FIG. The lower end of the drive link arm 16 is pivotally supported by 14 and the lower end of the driven link arm 17 is pivotally supported by the rear support shaft 15, and the upper end of the opposite drive link arm 16 and the upper end of the driven link arm 17 are lifted and lowered. Frame 18
The lower support shafts 14, 1 are attached to the connection plates 19, 19 at the rear end.
5, a cylinder 23 and a piston rod are supported on the tip end of a lever 22 which is pivotally supported by support shafts 20 and 21 which are arranged at the same interval as that of 5, and which is connected to the lower end of the drive link arm 16 at a required angle, and the upper end of the driving support frame 13. A prime mover 25, which expands and contracts the action points at both ends, is axially connected by spindles 26 and 27.
