ABSTRACT:
An air lumbar support is provided for establishing a desired attitude of a driver's seat of a vehicle, and is associated with an attitude control system. A pad of a seat back is supported by a plurality of air bags, each of which is connected with a solenoid valve, which when open, permits the air to be discharged into the atmosphere from the air bag. When a desired attitude is to be established, air under pressure is fed to the air bags. Attitude establishing data is in the form of a number of times the solenoid valves are energized for opening for short intervals, and is stored in a non-volatile semiconductor read-write memory if the attitude is to be registered. In response to a key operation, a microprocessor reads registered data automatically, initially driving an air pump, followed by opening the solenoid valves a number of times indicated by the data, thus establishing a desired air pressure in the air bag. In another embodiment, the solenoid valves are interposed between the air pump and the air bags.
