Abstract
A method and apparatus for controlling a lumbar support device provided in the seat back of an automotive seat. The control for support against the lumbar of an occupant on the seat is effected through manual and automatic control modes, and the automatic control mode emits alternating pulses for causing repeated alternating series of normal and reverse drives of a motor, to thereby move a lumbar support plate reciprocally forwards and backwards, offering a massage effect to the occupant's lumbar part.
