ランバーサポート装置。[Claim for Utility Model Registration] The latch rotates together with the cam due to the engagement and pressure of the pawl of the latch plate that is linked to the operating lever, and the displacement of the cam is changed to cause the biasing means to act on the lumbar plate. In a lumbar support device that adjusts the biasing force, a toggle spring is disposed between the cam and the frame, and the toggle spring has a toggle point where the direction of the biasing force is reversed on a line connecting the cam positions of maximum displacement and minimum displacement. , the rotation of the cam is restricted in the direction in which the cam displacement decreases, and the rotation of the cam is promoted in the direction in which the cam displacement increases. Features a lumbar support device.
