Air conditioning terminal

In an air conditioning terminal for supplying conditioned air into a space and including a plenum section connected to a source of conditioned air and a distribution chamber having a pair of assemblies for regulating the quantity of conditioned air discharged into the space, and means interposed between said plenum section and said distribution chamber for passage of conditioned air from said plenum section into said chamber, the improvement comprising:

• each of said air regulating assemblies including a pair of inflatable bladders mounted on a support member, each support member having at least two spaced apart upstanding arms;
• and
• a restraining member formed from spring-like material and connected to a non-movable portion of said terminal and to the outer surface of each upstanding arm of said support members to provide opposed horizontal forces on said upstanding arms to prevent relative movement in any direction in at least one plane between said air regulating assemblies and said non-movable portion whereby generation of noise by the relative movement of said assemblies is prevented.
