Device for transferring current between two contact points which are movable relative to each other
First Claim
1. In a device for transferring electric current between two contact points connected by a ribbon cable serving for the electrical connection, the cable having at least two electric conductors and being wound in the manner of a spring with its turns lying concentric to each other, and wherein ends of the cable are firmly attached to the two contact points, and at least one of the two contact points is movable relative to the other on a path concentric to the turns of the ribbon cable, the improvement comprisinga strip-shaped stabilizer of dimensionally stable plastic and having a U-shaped cross section which is bent to follow a radius of curvature of the ribbon cable, said stabilizer being at least as wide as the ribbon cable and closely enclosing the ribbon cable on opposite flat sides and one narrow side of said ribbon cable, and whereinsaid stabilizer, in cross-sectional dimensions, is long relative to its width.

Abstract
A device is described for transferring current between two contact points (6, 8) which are movable with respect to each other without the use of a sliding contact. A ribbon cable (10) wound in the manner of a spring housing is connected between the two contact points (6, 8). To protect the ribbon cable (10) from kinking, a guide (11) is arranged at each of the two contact points (6, 8), the guides closely surrounding the ribbon cable (10). The guide (11) is long in proportion to its width.

a strip-shaped stabilizer of dimensionally stable plastic and having a U-shaped cross section which is bent to follow a radius of curvature of the ribbon cable, said stabilizer being at least as wide as the ribbon cable and closely enclosing the ribbon cable on opposite flat sides and one narrow side of said ribbon cable, and wherein said stabilizer, in cross-sectional dimensions, is long relative to its width.
