Abstract
A seat for a vehicle may include a seatback including one or more inflatable bladders that may be configured to provide adjustable lumbar support and to deploy in response to a triggering event signal indicative of a change of velocity, collision, or predicted collision event. One or more inflatable bladders may be configured to be independently controllable and configured to provide adjustable lumbar support at a region of the seatback during normal vehicle operation. Moreover, when at least a portion of the back of an occupant of the seat pushes against a front surface of the seatback due to the event, the one or more inflatable bladders may be configured to compress at least partially a comfort foam or comfort material in the seatback and expedite engagement of the energy absorbing material with the occupant's back.
