Title:
PNEUMATIC CONTROL DEVICE FOR VEHICLE SEATS AND PNEUMATIC CONTROL METHOD FOR VEHICLE SEATS
Document Type and Number:
WIPO Patent Application WO/2017/199586
Kind Code:
A1
Abstract:
This pneumatic control device (35) for vehicle seats comprises a pump control unit (35b), an opening and closing control unit (35c), and a residual pressure exhaust control unit (35d). The pump control unit (35b) drives a pneumatic pump (31) to force air into airbags (10, 20) provided within a seat (1). The opening and closing control unit (35c) opens and closes intake valves (42, 44) provided in the air flow path communicating with the airbags (10, 20). After the the pneumatic pump (31) has stopped being driven, the residual pressure exhaust control unit (35d) opens an exhaust valve (43) provided upstream of the intake valves (42, 44) in the flow path, and thereby exhausts, from the flow path, the air trapped upstream of the intake valves (42, 44) in a closed position.
