Abstract

A gear mechanism part for a cable-controlled window lifter is provided that includes a gear wheel and a cable drum that can be driven by the gear wheel. The gear wheel and cable drum are disposed on a common axis. The gear wheel and the cable drum are coupled by a positive fit to an outside gearing disposed on an outside circumference projection. In the cable drum, a fitting chamber for cable end fastening is provided. The fitting chamber is disposed inside the outer circumference projection on a cross-sectional plane projected perpendicular to the axis. In this way, a more compact design of the cable drum and transmission of higher driving torque are achieved.
