A boundary position, which determines the range of the positions of the window within which trap prevention control is disabled, is set according to the sum of a first amount of rotation and a second amount of rotation. The first amount of rotation approximates a change, in a reference amount of rotation, that corresponds to a change in a detected voltage from a reference voltage. The second amount of rotation is set to a value that is smaller than the difference between a specific amount of rotation at a stop and the reference amount of rotation and is larger than the amount of variations in the reference amount of rotation.

A lifting device lifting and lowering a window glass of a door, the lifting device including a drive mechanism for lifting and lowering the window glass, a support plate supporting the drive mechanism, and a carrier attached to the support plate in a slidable manner, and lifted and lowered by the drive mechanism, wherein the support plate includes a through hole, and a stopper which is provided at an inner panel of the door and stops of the carrier is inserted through the through hole.

The disclosed embodiments relate to an electronic circuit for a motor-driven door of a rail vehicle, said electronic circuit having a series circuit of a first non-linear element and a first controllable switch between the motor terminals. The first non-linear element is poled such that the resistance thereof to a current generated by the drive motor during a closing movement of the door is greater than during an opening movement. If a supply voltage for the door is present, the resistance of the first switch is effected relative to the resistance when said supply voltage is absent. The invention further relates to a door module for a rail vehicle having such an electronic circuit, to a rail vehicle for such a door module, and to a use of the electronic circuit.
