Abstract
A lumbar support device for an automotive seat, in which a support arm, on which a lumbar support plate is rockably supported, is retained in a base bracket against movement by way of a biasing member and limiting element, under an unloaded condition. Therefore, the lumbar support plate does not give a pressure to the lumbar part of an occupant on the seat.
