Abstract: A braking system for a vehicle manual window-lifting mechanism prevents a window from dropping as a consequence of vibrations and minimizes angular play in a crank shaft. The system includes a helical spring that assists the crank shaft and that has a geometry modified from its conventional design. An included angle between the radial side pieces at which the winding ends terminate is an acute angle. One of the side pieces is coupled inside a radial hollow of the crank-driven shaft itself. The other side piece is located between the crank shaft and the drum, which rotate relative to each other. As a result, instead of the usual 40° or 45° of free play, the invention allows a maximum free play of only 10° to 15° in the crank shaft.
