DE2224760C2 - Windshield wipers, in particular for round or oval windows in motor vehicle lights - Google Patents

Description

The invention relates to a windshield wiper, in particular for round or oval windows of motor vehicle lights, with a wiper arm that is mounted outside the window and moved in a pendulum manner the end of which is attached to the bracket of a wiper blade via a fastening part.

Such a windshield wiper bids the unrecognizable The advantage that the drive elements of the wiper blade are all outside of the area to be cleaned Motor vehicle light, which usually forms a self-contained structural unit, arranged and fixed can be. The disadvantage of such a wiper is, however, that a ring segment-shaped wiped field is generated, which is only a limited Detected part of the pane to be cleaned. The wiping field is particularly small when the wiper blade is moved over round or oval panes and it must be ensured that it is the pane frame not overpainted.

It is the object of the invention to provide the windshield wiper mentioned at the beginning while maintaining the

, "To improve advantageous drive device so, that even with the wiping process over round or oval panes a much larger part of the The window is cleaned without the wiper blade entering the area delimited by the window surround leaves. This is achieved according to the invention in that the bracket is divided into two parts. d ;; ü the first part, aligned with the wiper arm, is rigidly attached to the fastening element and that the z \ wi'.e Part in "the extension of the wiper arm from-v-

JO aligns rotatably mounted on the mounting part. H, i this training of the wiper blade bracket can d. _{: i} rotatably mounted parts are rotated when hitting the blade * - beneath, so that the wiper arm pines sweeps over a larger wiping angle ·!

can. The angled Wibchblatt captures n-.in also the rounded end regionsc of the disk i; m: thus enlarges the wiped field.

The training and attachment of the parts of the U -..- gel on the fastening piece is solved in this way. d; .IS

the fastening part and the first part of the butt: r Via a square shoulder of the fastening part, a square hole in the first part of the bracket and \ rotatably against each other and you! - the fastening part and the second part of the bracket

Rotatable via a bearing pin of the fastening part and a bearing bore in the second part of the bracket are set to each other. For the sake of simplicity it should also be provided that the four-channel; paragraph and the bearing pin of the fastening piece as double stepped approach of the fastening part are formed with the same central axis.

The compulsory return of the rotatably mounted part of the bracket is achieved in that the Fastening part is designed as a chamber for receiving a helical spring, one end of which is in the Fastening part and the other end are set in a receptacle of the second part of the bracket. A limitation of the rotational movement of this part of the bracket can be achieved in that the end of the Helical spring, which is set in a receptacle of the second part of the bracket, also in one Recess is guided in the first part of the bracket, the end regions of which the rotary movement of the / widen Limit part of the bracket.

The invention is explained in more detail using an exemplary embodiment shown in the drawings. It shows

F i g. 1 shows a section through the fastening part the two parts of the wiper blade attached to it.

E i g. 2 the top view of the part of the wiper blade bracket rigidly attached to the fastening part and FIG

3 schematically shows that with the new windshield wiper generated wiping lines in a round motor vehicle light.

As the fig. 1 can be seen, the end of the Wiper arm 18 in a receptacle 'es fastening part 17 and can be replaced by an in the

Cewindaufnahme 19 screwed locking screw can be set therein. This fastening part 17 is designed as a chamber 16 for the helical spring 13. The end 20 of this coil spring 13 is in the receptacle 21 of the fastening part

17 set.

The bracket of the wiper blade, the cLn squeegee 12 receives is divided into the two parts 10 and 11. The part 10 is in the direction of the wiper arm

18 aligned non-rotatably fixed on fastening part 17. V - ': e F i g. 2 shows the part 10 Square hole 23. in which the square 29 of the attachment part 17 is guided. Part 11 has dagesien into the extension of the wiper arm 18 and is rotatably attached to the fastening part 17. to For this purpose, the part 11 is via a bearing bore 28 on the bearing pin 15 of the fastening part 17 rotatably mounted. The bearing pin 15 and the square 29 are as a double stepped approach on Supporting part 17 with a common millel axis from 2c educated.

As can be seen from the rivet collar 22, both parts 10 and 11 of the bracket on the fastening part are common held.

The other end 14 of the helical spring 13 is laid in a receptacle 27 of the part 11, so that. starting from the stretched middle position, the part 11 with a rotation according to one or the other Side is automatically returned to the extended position.

As the fig. 2 can be found. the part 10 has a segment-shaped recess in the fastening area on, in which the linden tree 14 of the screw down 12 KigL. The end regions 24 and 25 of this recess 26 then limit the rotary movement of the part by the stop of the end 14 of the helical spring 13 11 on fastening part 17.

The arrangement of the two bracket parts 10 and 11, 11, 17 can also be reversed on the fastening point 17
