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 (to) and an associated actuator () for acting on a door leaf. The actuator () acts on the door leaf with a travel-dependent force along its actuating travel(S). According to the invention, the electromotive drive (to) acts on the actuator () with the interposition of a rack-and-pinion gear (), wherein the rack-and-pinion gear () operates with different transmission ratios on the actuator () along its actuating travel(S).
