Abstract
A window regulator for raising and lowering a windowpane in a motor vehicle, and a vehicle door having at least one window regulator.
Claims16
A window regulator for a windowpane of a motor vehicle and which is framed by a window frame, the window regulator comprising:
- at least one guide rail having a linear guide section;
- a lower guide element configured as a lever element to which the windowpane is fastened, the lower guide element being configured to be guided substantially linearly in the linear guide section in an upward and downward direction, the first lower guide element having a guide shaft to operatively connect the lower guide element to the at least one guide rail, a linkage shaft spaced apart from and parallel to the guide shaft, and a lower windowpane-fastening shaft arranged parallel to and spaced apart from the guide shaft and the linkage shaft to rotatably connect the lower guide element to the windowpane, wherein the guide shaft and the linkage shaft are arranged at a first end of the lower guide element and the lower windowpane-fastening shaft is arranged at a second end of the lower guide element;
- an upper guide element having an upper windowpane-fastening shaft to rotatably connect the upper guide element to the windowpane, the upper guide element being configured to be guided substantially linearly in the linear guide section;
- and
- a drive mechanism rotatably connected to the lower guide element via the linkage shaft such that during a forced stop of linear movement of the guide shaft, and a further drive via the drive mechanism, the lower guide element performs a pivoting movement about the linkage shaft so that the linkage shaft is pivoted upwardly and inwardly, and an end of the lower guide element and the windowpane executes a movement perpendicular to the linear guide section so that the windowpane is pressed outwardly against a circumferential seal on the window frame.

A door for a motor vehicle, comprising:
- a window frame having a circumferential seal;
- a windowpane framed by the window frame;
- and
- a window regulator configured to raise and lower the windowpane relative to the window frame, the window regulator including:
- at least one guide rail having a linear guide section;
- a lower guide element configured as a lever element to which the windowpane is fastened, the lower guide element being configured to be guided substantially linearly in the linear guide section in an upward and downward direction, the lower guide element having a guide shaft to operatively connect the lower guide element to the at least one guide rail, a linkage shaft spaced apart from and parallel to the guide shaft, and a lower windowpane-fastening shaft arranged parallel to and spaced apart from the guide shaft and the linkage shaft to rotatably connect the lower guide element to the windowpane, wherein the guide shaft and the linkage shaft are arranged at a first end of the lower guide element and the windowpane-fastening shaft is arranged at a second end of the lower guide element;
- an upper guide element having an upper windowpane-fastening shaft to rotatably connect the upper guide element to the windowpane, the upper guide element being configured to be guided substantially linearly in the linear guide section;
- and
- a drive mechanism rotatably connected to the lower guide element via the linkage shaft such that during a forced stop of a linear movement of the guide shaft in the guide rail, and a further drive via the drive mechanism, the lower guide element is configured to perform a pivoting movement about the linkage shaft so that the linkage shaft is pivoted upwardly and inwardly, and an end of the lower guide element and the windowpane executes a movement perpendicular to the linear guide section, so that the windowpane is pressed outwardly against the circumferential seal.

A door for a motor vehicle, comprising:
- a window frame;
- a windowpane;
- and
- a window regulator configured to raise and lower the windowpane relative to the window frame, the window regulator including a guide rail arranged on respective sides of the windowpane to thereby guide the windowpane, the guide rail having:
- a linear guide section;
- a lower guide element having a Y-shaped cross-section that includes a guide shaft extending from a first leg portion at a first end of the lower guide element to connect the lower guide element for movement in the linear guide section in an upward and downward direction, a linkage shaft extending from a second leg portion at the first end of the lower guide element, and a windowpane-fastening shaft extending from a third leg portion at a second end of the lower guide element to rotatably connect the lower guide element to the windowpane;
- a first upper guide element having arranged spaced vertically apart from the lower guide element for movement in the linear guide section in an upward and downward direction, the first upper guide element having a windowpane-fastening shaft to rotatably connect the first upper guide element to the windowpane;
- and
- a drive mechanism rotatably connected to the lower guide element via the linkage shaft such that during a forced stop of a linear movement of the guide shaft, and a further drive via the drive mechanism, the lower guide element is to perform a pivoting movement so that the linkage shaft is pivoted upwardly and inwardly, and the lower guide element and the windowpane are to execute a movement perpendicular to the linear guide section so that the windowpane is pressed outwardly against the window frame.
