Abstract

A wiping device is proposed, which is used to clean windshields of motor vehicles. The wiping device has a driven wiper arm (12) to whose free end a wiper blade (14) is pivotably connected that is provided with an elongated, rubber-elastic wiper strip (32) and that can be placed against the window (20); the extending at least approximately in the wiping direction (24) of the wiper blade, the wiper strip is held, parallel to the longitudinal axis, on a striplike, elongated, spring-elastic support element (26), on whose middle portion one half (28) of a connection device (16) for the wiper arm (12) provided with the other device half (30) is contained. A wiping device of particularly low height is obtained if the wiper blade (14) is disposed next to the wart (12), viewed vertically to the window (20), and is pivotably connected to the wiper arm via the connection device (16).

Claims

1. A wiping device for windshields of motor vehicles, comprising a driven wiper arm having a free end;

a wiper blade pivotably connected to said free end of said wiper arm and provided with an elongated, rubber-elastic wiper strip, said wiper blade having a pivot axis extending at least approximately in a wiping direction and spaced apart from the window;

a strip like, elongated, spring-elastic support element which holds said wiper strip parallel to a longitudinal axis of said support element;

a connection device having one half provided on a middle portion of said support element and another half provided on said free end of said wiper arm, said wiper blade being disposed next to the wiper arm as viewed vertically to the window and is pivotably connected to said wiper arm via said connection device, said one of said halves of said connection device having a pivot pin, while the other of said halves of said connection device is provided with a bearing receptacle associated with said pivot pin, said pivot pin being disposed on said wiper blade, said bearing receptacle being located on said wiper arm.

2. A wiping device as defined in claim 1, wherein said halves of said connection device are provided with means for axially securing said pivot pin in said bearing receptacle.

3. A wiping device as defined in claim 1, wherein said half of said connection device which is provided with said pivot pin has a base body with two sides having projections which protrude in the wiping direction, said projections having longitudinal axes which are aligned with one another.

4. A wiping device as defined in claim 3, wherein said half of said connection device which is provided with said bearing receptacle has a U-shaped cross-section with two legs fitting over the sides of said base body, said bearing receptacle being disposed in each of said two legs for said projections disposed on the sides of said body.

5. A wiping device as defined in claim 3, wherein one of said legs is provided with a mount for the free end of said wiper arm.

6. A wiping device as defined in claim 5, wherein said mount has an insertion channel for the free end of said wiper arm and is provided with means for securing the end of said wiper arm in said insertion channel.

7. A wiping device as defined in claim 6, wherein said mount for said free end of said wiper arm is located next to said wiper blade.

8. A wiping device as defined in claim 1, wherein said half of said connection device which is provided with said bearing receptacle is composed of plastic.

9. A wiping device as defined in claim 1, wherein said half of said connection device which is provided with said bearing receptacle is composed of metal.

10. A wiping device as defined in claim 9, wherein said half of said connection device which is provided with said bearing receptacle is formed from a metal sheet.
