Embodiment Construction

[0031] figure 1 A frameless (vehicle) door 1 of a sedan or convertible is shown in . Arranged in the vehicle door 1 is a (vehicle) window 2 which can be adjusted along an adjustment path X by means of a window regulator 4 between an open position lowered into the vehicle door 1 and a closed position projecting out of the vehicle door 1 . When the door 1 is closed, the window 2 in its closed position rests (except for its lower edge which is arranged inside the door 1 ) against the door frame 10 (door and window) of the vehicle body holding the door 1 in its closed position. ) on the seal 8. When the vehicle door 1 is closed, the window 2 slides with its rear edge 12 along the seal 8 extending vertically in this region when the window 2 is adjusted. figure 1 The adjustment position x of the window 2 is shown between an open position and a closed position.

[0032] The window regulator 4 has an adjustment motor (hereinafter referred to as window regulator motor 14 ), which vi...

Abstract

The invention relates to an improved anti-trap protection system for a vehicle window (2) in a vehicle door (1), which can be adjusted by means of a window regulator motor (14) and is displaced into a closed position using a closing aid (22). As the vehicle window (2) is adjusted, a test variable (n) characteristic of the motor load is continuously recorded and compared to a threshold value (ns). The adjustment of the vehicle window (2) is stopped or reversed if this test variable (n) exceeds the threshold value (ns). In addition, a state signal (SB) characteristic of the state of activity of the closing aid (22) is recorded. The threshold value (ns) is set differently depending on the state signal (SB).

Description

technical field [0001] The invention relates to an anti-pinch protection method for vehicle windows and an attached anti-pinch protection unit. Furthermore, the invention relates to an adjustment system for a vehicle door having an adjustable window. Background technique [0002] In motorized windows (in particular side windows) an anti-pinch protection system is required for safety reasons in order to stop and possibly reverse the motor drive of the associated window regulator in the event of a pinch , that is, to reverse the direction of motion. In order to determine whether there is a entrapment situation (that is to say whether an object or a body part is trapped between the vehicle window and the opposite vehicle frame), characteristic parameters characterizing the operation of the window regulator drive are usually evaluated. Characteristic variables of this type are, for example, motor voltage, motor current or rotational speed. These characteristic parameters are ...
