A driving device and a vehicle window lifter are disclosed. The driving device includes a motor and a gearbox. The motor includes a stator and a rotor. The gearbox includes a housing and a gear. The motor is mounted in the housing and includes a rotary shaft driving the gear. The housing supports the motor through a soft support structure. Two bearings are mounted in the housing at the same side of the stator for supporting and determining an orientation of the rotary shaft. Over-constraint to the rotary shaft is eliminated by reducing the number of the rigid support points between the rotary shaft and housing. The soft connection between the motor and housing can avoid or reduce motor vibrations transferred to the gearbox.

The invention relates to a method for producing a gear worm (12) which is located in particular on an armature shaft (14) of an electromotive drive unit (10), wherein firstly a worm gear (20) having screw flanks (22) axially opposite one another on a longitudinal axis (18) is formed by means of a rolling tool, and subsequently a groove structure (24) which is concentric about the longitudinal axis (18) is formed on the screw flanks (22) by means of an additional process step. The invention also relates to a gear worm (12) produced according to the method according to the invention, and to a transmission drive unit (10) containing such a gear worm (12).

For the purpose of realizing an operationally reliable window lifter (opener) for a vehicle, there is provision to ascertain from an operating variable of a servomotor in each case a measure of a regulated position of the window pane in the course of a plurality of operating cycles of the window lifter in which a window pane of the vehicle is opened and closed again, in each case entirely or partly. In each operating cycle, or at least in selected operating cycles, the measure is normalized to a reference value if at the end of the respective operating cycle the window pane is driven by the servomotor for at least a predetermined blocked time beyond a blocked position. The blocked time is shortened if the normalization was not carried out for a predetermined number of consecutive operating cycles.

A gear motor assembly includes a motor and a gearbox connected together. The motor includes a stator and a rotor. The stator has a housing, magnets attached to the housing, and brushes.

A window positioning apparatus for a vehicle comprising a window panel, a frame in which the window panel is guided between a closed position closing a window opening in the frame and an open position opening the window opening, and a multi-stage telescoping screw actuator mechanism connected between the window panel and the frame, the actuator mechanism being extendible to move the window panel from its open position to its closed position and collapsible to move the window panel from its closed position to its open position. The multi-stage telescoping screw actuator mechanism includes a plurality of screw members of progressively decreasing diameter respectively telescopically disposed within a next adjacent screw member of larger diameter. The plurality of screw members includes a first stage screw member that is rotatably supported and axially constrained in a housing fixed with respect to the frame, a last stage screw member attached to the window panel, and at least one intermediate stage screw member, and each intermediate stage screw member has internal and external threads respectively for engaging external and internal threads on next adjacent screw members, such that rotation of the first stage screw member in a first direction relative to the last stage screw member will cause the intermediate and last stage screw members to extend telescopically along an extension axis from the first stage screw member and rotation in a second direction opposite the first direction will cause the intermediate and last stage screw members to telescopically retract.

An apparatus and a method for controlling and confirming a window are disclosed. An apparatus for controlling and confirming a window position, includes an input dial including a jog dial or a wheel dial and configured to input an input signal in response to a dialing operation by a user, a window configured to be opened or closed by a magnitude of the input signal inputted by the input dial, and a position confirming device configured to inform the user of a current window position in a tactile manner.
