Abstract
A system which takes direct action to reverse the rotation of the window driving motor includes an optical fiber conductor arranged inside a substantially prismatic profile forming loops at the points where said conductor enters and exits from a series of incisions formed at regular intervals in the lateral areas of said profile. The profile is fitted inside a covering in the frame of a door. The incisions comprise a mouth for insertion of the conductor through a passageway which ends in the cavity wherein the conductor is retained by an adhesive or the like. The optical fiber conductor may be arranged continuously over the entire length of the perimeter of the frame or over parts thereof.
