Abstract
A flexible shaft for transmitting torque, for example between a motor and an automobile seat to be adjusted. The shaft has a core including one or more wire layers helically wound in opposite winding directions. The outer layer has a number of wires with a circular cross-section and at least one flat wire. The wires of the outer layer are helically wound in a winding direction opposite to that of the adjacent layer. The flat wire has a thickness substantially less than the maximum diameter of the outer layer wires of circular cross-section. A strand of flocked yarn is wound on the flat wire and protrudes above the adjacent wires of the outer layer, to engage the inner wall of a surrounding casing and reduce noise when the shaft is rotated within the casing.
