ことである。(Means for Solving the Problems) The technical means of the present invention to achieve the above object is to divide the lower part of the seat part into two parts via the intermediate base, and to divide the lower part of the seat part and the intermediate base into two parts. A seat main body is formed by providing support legs that support the seat portion in a vertically movable manner, and a vertically movable elastic body is provided between the lower surface of the seat and the intermediate base to move the seat portion up and down by expansion and contraction. The slide frames provided on both sides of the lower surface of the seat body are slidably disposed on rails fixed to the seat mounting floor surface, and the seat body is moved forward and backward by expansion and contraction between the intermediate base and the mounting floor surface. A telescoping body for forward and backward movement is provided, and an engaging portion that can be freely engaged with the seat portion is provided at a required location on the upper surface of the intermediate base to restrict the vertical movement of the seat portion, and the engaging portion is connected to the horizontal portion. The vertically movable elastic body has a substantially L-shape consisting of a vertical portion, rotatably supports the bent portion thereof, and rotates the engaging portion by expanding and contracting between the tip of the horizontal portion and the upper surface of the intermediate base. An elastic body for an engaging part having a smaller capacity than that of the seat body is provided, and a latch part that can be freely latched to the rail is provided at a required location on the side of the seat body to restrict the forward and backward movement of the seat body. The stop part is provided with a rotatable stop in parallel with the stop part protruding from the side surface of the seat body, and the stop part is expanded and contracted between the stop part and the stop part. An elastic body for a hanging device having a smaller capacity than the elastic body for forward and backward movement that rotates the airbag is disposed, and each of the elastic bodies placed above overlaps a plurality of air bag bodies and connects them in a continuous manner. That's what happens.

When the airbag expands between the stopper and the hanging tool and extends in the direction in which the air bag bodies overlap and presses the hanging tool, the hanging tool rotates about the shaft support, and the rail and the hanging tool are rotated. The latching with the seat body is released, the seat body becomes able to move forward and backward, and each air bag body that is connected in a continuous manner that makes up the elastic body for forward and backward movement to which air is supplied inflates, and moves in the direction in which the air bag bodies overlap. When the sheet body is extended and moved forward or backward, and the supply is stopped at the optimum position, the air in the inflated elastic body for the latching device is discharged, the pressing force against the latching device is weakened, and the latching device is pivoted. The seat body is supported by rotating around the fulcrum and being hooked to the rail.
