Abstract
A linkage guides a flexible cable between two structures. The linkage includes a proximal arm with a proximal pivot joint for coupling the proximal arm to a first one of the two structures; and a distal arm which is coupled to the proximal arm by one or more intermediate pivot joints. The distal arm is shaped to follow a three-dimensional curve along a majority of its length. Shaping the distal arm to form a three-dimensional curve along a majority of its length enables the distal arm to pass through a relatively small aperture as the linkage is adjusted between its retracted and extended positions. It also enables the proximal arm to move in a locus of movement which does not interfere with other system components. The linkage can be used to guide a flexible cable between any two structures, for instance a fixed aircraft wing and a slat.
