Abstract:
A window-winder has a reversible drive unit (14), a pair of rails (12) and a pair of slides (66) for supporting and driving the window (10). The rails (12) have slitted tubular guides (50) in each of which a lateral appendage (71) of one of the slides (66) is engaged. Transmission members (16) extend each between the drive unit (14) and one of the rails (12). Each transmission member (16) comprises a fixed sheath (38) and a flexible, toothed pull-and-push cable (40). To allow the window-winder to be mounted equally well to e.g. a right-hand or a left-hand door of a motor vehicle, the drive unit (14) is adapted to be fixed to a sidewall located on its one side on the other. The lateral appendage (71) of each slide (66) and a corresponding end portion (38a) of each sheath (38), on one hand, and a lower portion of the rail (12), on the other hand, are rotatably mounted with respect to each other.
Abstract:
The cable is constituted by an elongate body (10) of thermoplastic material with or without a central reinforcing core (12). The body (10) is generally cylindrical and has at least one rack in the form of a set of teeth (14), the teeth (16) of which are stamped in its surface and have cross-sections which are uniform along chords of the cylinder. The cable is preferably manufactured by a method according to which a semi-finished product of thermoplastic material is extruded and is then shaped continuously by hot deformation.
