• a compact and at the same time robust construction of the drive is in the foreground, which has a drive motor and a feed drive connected downstream of the drive motor with a push rod.
• the push rod is coupled to the tailgate to transfer the drive torque required for the engine adjustment to the tailgate.
• the known drive (DE 20 2008 016 929 Ul), from which the invention proceeds, is equipped with a restorable drive train, so that a manual adjustment of the adjusting element without the need for a separating clutch is possible.

It is accepted that the braking of the motor shaft is continued even during the motorized adjustment of the tailgate.
• the motor shaft carries in the known drive a worm, which meshes with a worm wheel.

• a brake assembly is provided, which brakes exclusively a driven side introduced movement, and not a drive side introduced movement.
• the advantage here is the fact that the motor adjustment is not "disturbed" by the brake assembly.
• the invention is based on the problem, the known drive for the motor adjustment of an adjusting element of a motor vehicle in such a way and further, that the design of the drive train on the one hand and the brake assembly on the other hand is simplified for achieving a predetermined braking behavior.
• the fundamental consideration is to design the powertrain with regard to optimal repatriation. Specifically, it is proposed that the drive train between the motor shaft of the drive motor and the drive wheel exclusively has spur gear stages with parallel aligned spur gears. This can be a particularly simple way to generate a good repatriation of the drive train with low internal friction in the above sense.
• the braking behavior of the drive at the output side initiated movement is largely determined by the brake assembly, and less by the internal friction of the gear stages, which greatly simplifies the design of the brake assembly.
• another brake arrangement can be used, which can be easily adapted to the respective boundary conditions.
• the spur gears are preferably designed as gears. In principle, however, the use of friction wheels is conceivable here.
• the preferred embodiment according to claim 3 allows a motor-Ver position with low, due to the brake assembly mechanical losses and a secure fixation of the adjusting element in intermediate positions, for example, in a loss of current.
• the particularly preferred embodiment according to claim 8 allows an extremely compact design in that the spur gears of the drive train are arranged in at least three aligned perpendicular to the gear axes Stirnradebenen, wherein at least one inner Stirnradebene, which is enclosed by two outer Stirnradebenen, by an intermediate shaft in a sense " With such a design, several gear stages can be readily realized without the expansion of the drive being too large perpendicular to the spur gear axes.

• This is advantageous because the spur-gear stages 8-11 supplement to a reduction gear, so that when a manual adjustment of the tailgate 2 on the first spur gear 8 "incoming" torque is comparatively low applied braking torque is the lower, the closer the point of action of the brake assembly 12 to the drive motor 3 is located. It is even conceivable, for example, even that the brake assembly 12 seen from the drive motor 3 acts on the drive train 7 immediately before the first spur gear 8, which corresponds to a braking action on the motor shaft 3a.
