The invention relates to a drive assembly for the motorized adjustment of an adjusting element (1) of a motor vehicle, wherein at least one drive (2) having an electrical drive motor (3), in particular a direct current motor, and a drive controller (5) associated with said drive (2) and connected to a supply voltage Uv are provided, wherein said drive (2) is designed to not be self-locking, so that the drive motor (3) operates as a generator in the case of a non-motorized adjustment of the adjusting element (1) and creates a generator voltage UG. According to the invention, the drive controller (5) is equipped with an overvoltage protection (6) that can be triggered by exceeding a threshold supply voltage Uv, and the assembly is furthermore designed such that said overvoltage protection (6) can additionally be triggered by a non-motorized adjustment of the adjusting element (1) upon exceeding a threshold generator voltage UG.
