Abstract
A vehicle seat having a seat portion, a support frame for the seat portion, a back rest portion and an independently adjustable, front thigh support slidably supported at the front of the seat portion. A pair of spaced slideways define a slide path for the thigh support extending from a fully retracted position to a fully extended position. In a first embodiment of the invention, the slide path is inclined upwardly in a forward direction at an angle which is sufficiently small enough that the sliding friction between the slideways and corresponding slide members of the thigh support prevents the weight of the thighs of a person sitting in a seat from moving the thigh support in a retracting direction. In a second embodiment of the invention, the slide path lies in an upwardly extending curved surface. A pair of biased locking members are movable between unlocked and locked positions on their respective slideways to alternately unlock and lock the thigh support in any selected position between the fully extended and retracted positions.
