ABSTRACT:
An inflatable thigh support for a vehicle seat includes an extension which is hinged to the forward edge portion of a seat cushion support for movement between a fully lowered position and a fully raised position and various positions therebetween. The extension is moved between its positions by an inflatable bladder which is secured thereto and to the seat cushion support. A foldable forward portion of the seat cushion overlies the bladder. The inflation of the bladder folds the foldable portion of the cushion as the extension is raised and provides a firm support for the thighs of a seat occupant.
