Claims

[Scope of Claim for Utility Model Registration] In a side support device for a seat, which includes movable side support frames attached to a seat back frame on both sides, and which supports a seated person from both sides by moving the side support frames and changing the interval between them. Each leg of the roughly inverted U-shaped stay is fixed to the seat back frame, and the center part of the stay is loosely inserted through the horizontal long hole drilled in the side support frame, so that the split bushing on the side support frame is inserted into the center of the stay. The elastic body on the side support frame elastically presses the top surface of the bushing, creating frictional resistance between the side support frame and the stay through the bushing, and this frictional resistance causes the side support frame to move against the stay. A side support device for a seat, the side support device for a seat being characterized by regulating the left and right sliding of the seat and defining the sliding range by a gap between a long hole in the side support frame and the center of the stay.
