Abstract:
A method of upgrading a bed assembly from a first configuration in which the bed assembly includes a foam mattress, an articulating frame for supporting the foam mattress, and a drive system for moving at least one section of the articulated frame, to a second configuration in which the bed assembly includes an air mattress, the articulating frame, and the drive system, the method comprising the steps ofremoving the foam mattress from the articulating frame,placing the air mattress that includes at least one air bladder on the articulating frame,coupling an air control module pneumatically to the at least one air bladder, andcoupling the air control module electrically to the drive system so that command signals received by the drive system to adjust pressure of the at least one air bladder are processed by the drive system, the drive system generating output signals that are routed from the drive system on the air control module to operate the air control module to adjust pressure of the at least one air bladder.
