Abstract
A pilot seat or the like provided with lumbar support and armrests. Research into the anthropometry has revealed that the height of the armrest and the center of the lumbar support of people between 5'2" and 6'3" are practically the same. Accordingly, a unitary adjustment means is provided for simultaneously raising or lowering the armrests and the lumbar support.
