Abstract
A structure for adjusting the height of the seat of an automotive vehicle including a handle-operated coupler for pivoting supporting members at the four corners of the cushion, the supporting members being mechanically coupled together for raising or lowering the cushion vertically upon the pivoting of an activator supporting member adjacent the handle. The coupler includes a driving device and a coaxial driven device operatively interconnected by a spring coiled about at least a portion of the driving device and driven device, and a housing including a shell closely fitted about the coiled spring. A driven pin is securely fitted to the actuator supporting member for pivoting the actuator supporting member upon the application of lateral force to the driven pin. The driven device includes a driving pin linked to the driven pin for pivoting the actuator supporting member upon the rotation of the handle. A load on the cushion applies a reverse force on the driving pin through the driven pin and link expanding the coiled spring against the shell to maintain the cushion at the adjusted height.
