Abstract
An automotive seat assembly comprising a seat cushion and a seat back. The seat back includes opposing sides defining a center line there between and a lower pelvic support region for supporting the pelvic area of a seat occupant. An inflatable bladder assembly is supported by the seat back and includes a pair of bladders positioned on opposing sides of the center line in the pelvic support region which are expandable by a fluid medium from a generally flat uninflated condition to a generally wedge-shaped inflated condition. A controller activates a fluid pump and valve to control the bladders between the uninflated and inflated conditions. When the bladders are expanded to the inflated condition, the wedge-shape of the bladders cradles the spine and pelvic bone of the seat occupant to control pelvic rocking and reduce spinal muscle fatigue.
