Abstract
The invention relates to an opening device for a motor vehicle door, in particular a handle-free motor vehicle door such as, for example, a handle-free motor vehicle side door. For this purpose, the opening device has an electromotive drive (1 to 4) and an associated actuator (5) for acting on a door leaf. The actuator (5) acts on the door leaf with a travel-dependent force along its actuating travel (S). According to the invention, the electromotive drive (1 to 4) acts on the actuator (5) with the interposition of a rack-and-pinion gear (7, 8), wherein the rack-and-pinion gear (7, 8) operates with different transmission ratios on the actuator (5) along its actuating travel (S).
