Abstract: An assembly is composed of a transducer (33), an actuator arm (34), an inflatable envelope (30) including two flat surface portions, one of which surface portions is secured to the actuator arm and on the other of which surface portions is mounted the transducer, means (72) for inflating the envelope so as to move the transducer into an operating position and for deflating the envelope so as to return the transducer to a rest position, and reinforcements (40,42,56), associated with the parts of the envelope between the flat surface portions, for maintaining the flat surface portions substantially parallel to each other when the envelope is inflated. … The envelope (30) is formed from a flexible non-elastic material, and the reinforcements (40,42,56), both constantly maintain the flat surface portions substantially parallel to each other and constantly maintain the parts of the envelope between the flat surface portions substantially parallel to each other.
