Seating and lying surfaces of current sitting and lying devices are versatile and upholstered in the most varied of ways. All but the usual upholstery is more or less rigid. They are ^ immobile, dead surfaces that give way under load,

but are not adapted to the optimal body contour in each case and

p not constantly changing contours under its own power

can participate. The upholstery contour cannot do this manually either

$ Changing contours need to be adapted sen.

(' According to the invention this is solved and made possible by close together

Tubular or conical, embedded in the upholstery, rubber-elastic membrane chambers. The chambers are firmly in one

f highly elastic filling compound and give their movement mainly

sullen upwards. All membrane chambers are in the automatic

■ Body contour adjustment with one another and with one another by means of hoses

connected. The chambers are communicating with one another and exchange air with one another. The more stressed areas of the lying surface are pressed down and press air into the less loaded chambers. In this way, the upholstered surface continuously adapts to the contours of the body. This automatic contour padding is relatively soft. .) The manual contour upholstery, on the other hand, is freely adjustable, after each setting, however, firm upholstery surface contour. The chambers are individually connected to a main pressure hose by means of hose ends. Between the individual hose ends of the membrane chambers and the main pressure tube pushbutton switches are switched that allow three switching operations. Air out of the chamber; Air passage closed (neither air in still out); Air in the chamber. The main pressure hose is connected to a compressed air tank. The container can be a simple compressed air cylinder that is changed occasionally, like a cartridge in the filler or which is refilled by case 1. But it can also be a compressed air tank with an electrically operated compressor is connected, which constantly maintains the target pressure in the container. The compressor would be switched on and off by a uanometer switch on the compressed air tank will.

The aforementioned body contour upholstery can be used for chairs, armchairs, car seats, Beds, couches and the like are used / ended. Many more variations are available possible and give the invention a wide range of applications,
