(Prior Art and Problems Thereof) Conventionally, as a vehicle seat of this type, the actual construction of 63-58
There is a prior art as described in No. 46. In this prior art, a slide rail provided at the lower portion of the seat is moved back and forth in conjunction with a screw that rotates by the start of a motor, and a slide shaft supported at the front end of the rail is installed. From the initial point of starting the forward movement of the slide rail and the forward movement of the slide rail, the double link folded on the back side of the cy support plate extends fully and the sill support plate interlocks until the cy support plate faces upward. The purpose of this is to prevent the cy support plate from rotating up and down.

However, in the above technology, the cysupport plate does not completely face upward until the folded double link is fully extended from the initial stage of the forward movement of the slide rail, and the cysupport plate is not ready for use. The plate cannot be used until a certain distance has passed, and the vertical rotation of the cysupport plate could not be adjusted arbitrarily, resulting in a limited usable position and a tilted state of the cysupport plate. Is also limited and could not be widely applied to users.

The vertical movement and back-and-forth movement of the cy support plate of the cy support part are automatically adjusted separately by expanding and contracting the expansion and contraction body that is formed by stacking a plurality of air bag bodies that are in communication with the air supply device and joining them in a continuous manner. Since the optimum position suitable for each user can be selected at any position, a wide range of support is possible, and there is no limitation on the use position of the support plate as in the conventional vehicle seat, which is extremely convenient.
