Pneumatic controller for vehicle seats

Abstract

Disclosed is a pneumatic controller for vehicle seats, in which a main printed circuit board is mounted in a housing, and a plunger of an actuator pulls or pushes a sub-printed circuit board by a switching signal, in a state in which the sub-printed circuit board provided with pressure sensors is fastened to the main printed circuit board so as to be slidably movable and exchange electrical signals with the main printed circuit board, thereby enabling the pressure sensors on the sub-printed circuit board to move to a different position where the pressure sensors are capable of sensing air pressure, and accordingly being capable of easily detecting not only air pressure during air intake and exhaust for first air cells installed in a seat cushion and second air cells installed in bolsters bus also air pressure during air intake and exhaust for third air cells installed in a seat back.
