Abstract

Various embodiments relate to a drive arrangement for a closure element of a motor vehicle which has an electrical motor vehicle on-board power system, wherein an electric drive for motorized adjustment of the closure element is provided, wherein the drive is assigned a coupling arrangement by which the drive can be actuated electrically. It is proposed that at least one cableless transmission path, in particular to an on-board-power-system-side coupling arrangement, via which the drive can be actuated, can be generated by the drive-side coupling arrangement.
