Document Type and Number:
Japanese Patent JPH0226372
Kind Code:
Y2
Abstract:
An air-controlled lumbar support apparatus for a vehicle seat having a base member and a backrest is provided and includes an inflatable chamber, a valve mechanism, and a pneumatic tube. The inflatable chamber is mounted within the backrest and includes at least one partition disposed across a substantial portion of the at least one inflatable chamber. The valve mechanism receives and discharges a flow of pressurized fluid. The pneumatic tube interconnects the valve mechanism and the inflatable chamber for transferring the flow of pressurized fluid. A pump is attached to the valve mechanism for injecting fluid through the valve mechanism and the pneumatic tube to inflate the inflatable chamber. A switching mechanism allows for the release of fluid out of the valve mechanism, thereby deflating the inflatable chamber, as desired.
