Abstract: An air bedding system with a diapghagm pump built into it. The diaphragm pump is comprised of a shaft, means for rotating the shaft at a speed of less than 3,300 revolutions per minute, a first connecting rod connected to a first diaphragm and operatively connected to the shaft, a second connecting rod connected to a second diaphragm and operatively connected to the shaft, and means for converting rotary motion of the shaft into reciprocating linear motion of both the first connecting rod and the second connecting rod such that, as the first connecting rod is moved in a first direction at a first rate of travel, the second connecting rod is simultaneously moved in a second linear direction at a second rate of travel, which is equal to said first rate of travel, and wherein the second linear direction is the opposite of the first linear direction.

Abstract: An airbed mattress assembly comprised of an air core disposed within a mattress cover, a layer of impact absorbing material with a thickness of from 0.5 to 1.5 inches contiguous with the bottom surface of the air core, an air blower having an intake to atmospheric air and having an exhaust to atmospheric air and having a pressurized air outlet, an air line connected to the pressurized air outlet and connected to the air core, an air valve, means for actuating the first air valve for opening air flow through said first air line and for simultaneously energizing the air blower, and means for actuating the air valve for opening air flow through the air line without simultaneously energizing the air blower. The air core has a depth from about 8 to about 12 inches, a length of from about 80 to about 84 inches and is formed from vulcanizing a multiplicity of sections of calendared material which comprises elastomeric material bonded to a fabric material.
