Abstract: A multiple air compartment adjustment device includes at least two air compartments, an adjustment unit, at least one positioning member. The air compartments are arranged in a tiered form. The air compartments include, in an interior thereof, an elastic body. The adjustment unit includes at least two valve assemblies, which include a connection valve, a self-charging valve, and an operation section. The positioning member is movably disposed on the adjustment unit and one of the positioning member includes an activation section. The air compartments are automatically operated to adjust for high, low, soft, stiff, and shape according to a magnitude of a pressing force and after the pressing force acting disappears, inflation can be automatically carried out for shape restoration to prevent the elastic body from elastic fatigue and deformation.

Abstract: A valve positioning structure is provided for pressing down a switch arranged in a valve so that fluid is allowed to flow through an inlet opening of the valve when the switch is pressed down in order to control the fluid to flow into/out of at least one bladder. The valve positioning structure includes a casing that receives the valve therein and the casing is provided with a contact member and a manipulation member respectively and movably on upper and lower surfaces of the casing. The contact member and the manipulation member are coupled to each other so that the contact member is operable to drive the manipulation member to move. The manipulation member includes an operation section, where the operation section is movable toward and is enabled to press down the switch when the manipulation member is driven by the contact member to move toward the switch.

Abstract: A height adjusting structure with directly communicating airbags includes at least two airbags, where the airbags each receive and retain therein an elastic body. One of the airbags includes an air control unit connected thereto for controlling air filling and discharge of the airbags. The airbags are provided, in surfaces thereof that opposes each other, with corresponding passage holes and joint sections formed around circumferences of the passage holes. The joint sections are jointed so that the airbags are directly connected with no additional medium between the airbags and allowing the airbags to share the same air control unit to achieve flowability of air between the airbags, whereby advantages of efficient air filling and discharge of the airbags, being easy to manufacture, and reducing manufacture costs can be achieved.
