ABSTRACT:
An angled support arm for a sun-visor which is electrically powered by at least two conductors passing inside the support arm. The support arm is made by molding a plastic material over at least a portion of the conductors in such a manner as to cause the plastic material to constitute a block with the conductors. In the method of the invention, overmolding takes place in two stages: a first stage in which a plastic material is molded over the conductors in such a manner as to obtain a support arm blank having at least a portion which is smaller in section than the corresponding section of the support arm; and a second stage during which the blank is itself overmolded to obtain the finished support arm.
