Abstract
A contour-adjustable seat, particularly a vehicle or aircraft seat, has a backrest (2) and possibly lateral support pieces (4) whereby there are gas or air-inflatable cushions (5a, 5b, 5c) provided on a common flexible modular support unit (M), possibly designed as a separate component, whereby the modular support unit (M) serves as a common support surface for the cushions, which are each connected to a source of compressed air or gas via a line provided with a controllable valve, whereby each valve communicates with a control unit for air or gas pressure via a control line, and whereby a pressure sensor is provided for each cushion. Additional components for the contour adjustment system are integrated in the modular support unit, such as. valves for cushions and/or for pressure sensors, to obtain a system that is simple in the assembly of the seat and is also well-suited for possible retrofitting, and subsequently requires less space and is lighter than conventional systems.
