Abstract

An apparatus for connecting a wiper blade for windows of motor vehicles to a driven wiper arm guided on one end of a motor vehicle with a free end of the wiper arm being pivotably connectable to a support element for an elongated, rubber-elastic wiper strip that can be applied to a window, has a connection unit of a wiper blade including one journal protruding from each of long sides of the support element, with a common longitudinal axis of both journals located transversely to a length of the support element in a plane parallel to the window, each of the journals engaging a bearing recess of the wiper arm, which recess forms a connection unit of the wiper arm, each of the bearing journals being introducible via a respective mounting that is open at an edge and opens into the bearing recess, each of the journals being formed of at least two spaced-apart, elastically deflectable journal parts, and a width of each mounting channel being less than a least journal dimension measured transversely to a longitudinal journal axis.

Claims

1. An apparatus for connecting a wiper blade for windows of motor vehicles to a driven wiper arm guided on one end on a motor vehicle, with a free end of the wiper arm being pivotably connectable to a support element for an elongated, rubber-elastic wiper strip that can be applied to a window, the apparatus has connection means of the wiper blade including one journal protruding from each of long sides of the support element, with a common longitudinal axis of both journals located transversely to a length of the support element in a plane parallel to the window, each of the journals engaging a bearing recess of the wiper arm, which recess forms connection means of the wiper arm, each of the journals being introducible via a respective mounting channel that is open at an edge of the wiper arm and opens into the bearing recess, each of the journals being formed of at least two spaced-apart, elastically deflectable journal parts, and a width of each mounting channel being less than a least journal dimension of the spaced journal parts measured transversely to a longitudinal journal axis.

2. An apparatus as defined in claim 1, wherein the journals are each formed of the journal parts provided each with two opposed flat faces located inside an imaginary annular jacket face spacing between the two journal parts being formed by a slit that extends at least far as a coupling part composed of elastic plastic for the journals, and the slit being disposed between the two flat faces.

3. An apparatus as defined in claim 1, wherein the mounting channels are formed so that they are adapted to extend substantially parallel to a surface of the window.

4. An apparatus as defined in claim 1, wherein the mounting channels are formed so that they are adapted to extend from the bearing recesses towards a surface of the window.

5. An apparatus as defined in claim 4, wherein a spacing between the journal parts is formed by a slit which extends at least as far as a coupling part made of an elastic plastic for the journals, the slit being oriented pointing towards a surface of the window.

6. An apparatus as defined in claim 1, wherein the mounting channels have side walls facing one another and diverging from one another beginning at the bearing recesses.

7. An apparatus as defined in claim 1, wherein the support element is formed as a band-shaped, elongated rail of a spring elastic material, on which the wiper strip is retained with a longitudinal axis extending parallel to the band-shaped elongated rail.

8. A wiper blade for windows of motor vehicles, comprising an elongated, rubber-elastic wiper strip applicable to a window;

a support element having a longitudinal side on which the wiper strip is arranged, the support element having two further longitudinal sides provided with connecting means which are operative for connecting a wiper arm thereto, the connecting means including two journals having a common longitudinal axis extending transversely to an extension of the support element, each of the journals being formed of at least two spaced-apart, elastically deflectable journal parts, so that the journals are insertable into corresponding mounting channels formed on the wiper arm and said channels being smaller than the least journal dimension measured transversely to the longitudinal axis of the journals.

9. A wiper blade as defined in claim 8, wherein the journals each formed of the two journal parts are provided each with two opposed flat faces located inside an imaginary annular jacket face, with a space between the two journal parts being formed by a slit that extends at least as far as a coupling part composed of elastic plastic for the journals, and the slit being disposed between the two flat faces.

10. A wiper blade as defined in claim 8, wherein the support element is composed of a plural ity of parts.
