Abstract:
A raising device for car windows comprising:an elongated guide extending along a longitudinal axis and having opposite ends, the elongated guide being arranged symmetrically with respect to a symmetry axis spaced equidistantly between the opposite ends of the elongated guide; a respective roller mounted rotatably at each of the opposite ends; a gliding element mounted slidably on the elongated guide for supporting a car window; a motor operatively connected to the gliding element; and at least one cable, a first portion of the cable extending from one of the rollers to the motor and a second portion of the cable extending from another one of the rollers to the motor, the cable being guided by the rollers and coupled to the motor and to the gliding element such that when the motor operates in a first condition, the gliding element is displaceable to a first position in which the car window is open, and when the motor operates in a second condition, the gliding element is displaceable to a second position in which the car window is closed, wherein the motor is adapted to be fixed at a location relative to the elongated guide, such that lengths of the first and second portions of the cable are substantially the same on either side of the symmetry axis.
