"Window regulators, especially for curved ones
Side windows of motor vehicles "

The invention relates to a window regulator, in particular for curved ones Side windows of motor vehicles, in which the panes in side guide rails are movable.

Especially with more curved ones, in the conventional way on both sides in guide rails throughout the entire stroke range, e.g. with plush-like Lined with fabric, guided disks cause high frictional forces due to the non-parallelism of the guide rails and the entanglement of car body parts in the ferry service, different expansions, etc. on the have the effect of high operating torques on the window crank.

Bs is an object of the invention to provide a window guide and a FEN g sterhebor also to provide for curved panes, wherein a light Bedienharkeit of the window lifter Bel all driving conditions must be ensured.

Tube, is arranged through the at least one with the lower edge the disc firmly connected guide part is guided vertically.

The guide part can advantageously be used as a two-legged sliding bracket be formed, the legs of which slide on the guide column Plastic or fabric-clad metal can be made.

Each leg is preferably in two parts in the form of jaws, constructed to engage around the guide column.

According to a preferred embodiment of the invention, the accesses Shifting the disc to the required force on the sliding bracket.

In the case of a window lifter equipped with a gear crank drive, this advantageously acts via a curved lever provided with a guide slot on a pin attached to the sliding bracket.

In order to achieve a cushioning of the disc when it is completely lowered, a buffer body made of elastic material can be arranged on a base plate of the guide column.

To the sliding on a guide column designed in the form of a tube To secure the guide part, e.g. a sliding bracket, against rotation, the cross-section of the tube can advantageously be oval.

The subject matter of the invention will hereinafter be based on one in the enclosed legends Drawing showing a car seen from the interior teLlwuise In the 3 section shows the illustrated embodiment example in more detail will.

The pane 1 of the door shown is guided in the area of the window opening in guide rails 2 which extend essentially only over the height of the window opening. In the interior of the door there is a guide pillar 3 adapted to the curvature of the pane 1 in the form of a tube with an oval cross-section, which serves to guide a slide bracket 5 attached to a support rail 4 on the lower edge of the pane 1. The sliding bracket 5 has two legs 6 and 7, which are arranged at the greatest possible distance from one another in order to avoid tilting. The legs 6 and 7 are each formed in two parts in the form of jaws which umgrei- the FUhrungssKule 3 ä fen. The jaws, which are preferably made of plastic, are connected by screws 8, by means of which the contact between the jaws and the guide column 3 and thus the friction that occurs when the disk 1 is moved up and down can be changed. The gear crank drive IO, which is actuated by a hand crank 9 and not shown in detail, acts via a curved lever 11 and a guide slot 12 provided in it on a pin 13 which is arranged on the upper leg 6 of the sliding bracket 5. A buffer body 15 made of elastic material is attached to a base plate 14 of the guide column 3 for soft interception of the completely lowered disk 1.

The window guide according to the invention results in a gradual transition from the statically overdetermined window support to the guide slide nen in a statically determined three-point guide - at least at about rectangular panes - when the pane is lowered, thereby reducing the force required to operate the window crank.
