Abstract
A pressure control apparatus includes an air pump which is pneumatically connected to an air mattress, with an air pressure sensor in the mattress for detecting the current air pressure within the mattress. A central control unit is interconnected with the pressure sensor and the air pump and is programmable to add or remove air from the mattress to control the pressure within the mattress. A plurality of position sensors in the mattress will detect the posture and/or position of an occupant of the bed and transmit this information to the control unit. The control unit can then determine the actual position of the occupant and adjust the air pressure within the air mattress accordingly.
