ABSTRACT:
A support assembly for supporting a retractable device includes a frame, at least one arm movably mounted on the frame for carrying the device between a retracted position for stowing the device, and an extended position for presenting the device, and a reactionator couple operatively connected to the arm for resisting, in part, against the arm when it is moved from the extended position to the retracted position, thereby slowing the rate at which the device is retracted.
