Abstract
Abstract The present invention provides a pedestal seat for a vehicle, such as a car, having a base comprising a base shell and a pair of elongated rails secured to the bottom of the base shell so that the rails are spaced apart and parallel to each other. These rails are, in turn, longitudinally slidably mounted to tracks secured to the vehicle floor. A pair of hinges are directly secured to the rear ends of the rails while a back plate is pivotally mounted to the hinges. A back shell is attached to the back plate and both the base shell and back shell are subsequently covered by seat and back cushions, respectively, so that the hinges are hidden from view. Since the rails, hinges and back plate form the support structure for the seat, the base shell and back shell can be easily interchanged to facilitate styling changes. In addition, two or more bladders are variably inflatable to provide upper back and head support.
