The seat, esp, vehicle seat, has two self-inflating cushions, in the sides of the seat. There are two similar cushions (28,30) in the sides of the back rest. These are valves to adjust the air volume in the cushions. All valves are operated simultaneously by a common element (42). There is a cushion, to adjust the inclination of a head support. The cushions in the seat are pneumatically connected, and so are the cushions in the back rest. There is a single valve (26,48) for the head support; a single valve (22,44) for the cushions in the seat; and a single valve (24,46) for the cushions in the back rest. |
