Abstract

The invention relates to a wiper blade ( 10 ) designed as a flat bar with a wiper strip ( 12 ) which is held by a spring-elastic strip support element ( 14 ) that is pre-curved in a concave manner with respect to a wiper lip ( 16 ) of the wiper strip ( 12 ). One or more spoiler parts ( 22, 23 ) are attached to the support element ( 14 ) face facing away from the wiper lip ( 16 ) by means of guiding profiles ( 30 ) which cover the support element ( 14 ) from the outer longitudinal faces and project to a certain extent with respect to the outflow side ( 26 ) of the spoiler part ( 22, 23 ) and which form a groove ( 31 ) with said outflow side. A connecting element ( 18, 64 ) is fixed in the central region of the wiper blade ( 10 ) for connecting a wiper arm in an articulated manner. According to the invention, the guiding profile ( 30 ) on the outflow side ( 26 ) has a guiding ridge ( 32, 34, 40 ) on the guiding profile longitudinal face pointing outwards.

First claim

What is claimed is:

1. A wiper blade ( 10 ) of flat bar construction, having a wiper strip ( 12 ) which is held by a band-like, resiliently elastic carrier element ( 14 ) which is pre-curved in a concave manner with respect to a wiper lip ( 16 ) of the wiper strip ( 12 ), wherein one or more spoiler parts ( 22 , 23 ) are mounted by means of guide profiles ( 30 ) on a side of the carrier element ( 14 ) which faces away from the wiper lip ( 16 ), which spoiler parts enclose the carrier element ( 14 ) from outer longitudinal sides and protrude to a small extent beyond a flow-off side ( 26 ) of the spoiler part ( 22 , 23 ) and form, with said flow-off side, a fillet ( 31 ), and wherein an attachment element ( 18 , 64 ) for the articulated connection of a wiper arm is fastened in a central region of the wiper blade ( 10 ), characterized in that the guide profile ( 30 ) on the flow-off side ( 28 ) has a guiding rib ( 32 , 34 , 40 ) that is a thin piece that projects laterally outwardly from a remainder of the guide profile ( 30 ) along a plane that is coplanar with the carrier element ( 14 ), and wherein the guiding rib ( 32 , 34 , 40 ) terminates at a laterally outward end.

2. The wiper blade ( 10 ) as claimed in claim 1 , including two spoiler parts ( 22 , 24 ), of which an inner spoiler part ( 22 ) extends from an inner end of the wiper blade ( 10 ) to the attachment element ( 18 , 64 ) whereas an outer spoiler part ( 24 ) extends from an outer end of the wiper blade ( 10 ) to the attachment element ( 18 , 64 ), wherein one or both spoiler parts ( 22 , 24 ) has a guide profile ( 30 ) with a guiding rib ( 32 or 34 respectively).

3. The wiper blade ( 10 ) as claimed in claim 1 , characterized in that, in a region ( 36 ) extending over the attachment element ( 18 ), a connecting piece ( 52 ) forms, by way of a connecting strip ( 54 , 60 ), a guiding rib ( 40 ) which, in a longitudinal direction to both sides of the attachment element ( 18 ), and by way of retention elements ( 58 , 62 ), is hooked onto the one or more spoiler parts ( 22 , 24 ) and adjoins the associated guide profiles ( 30 ) or the guiding ribs ( 34 , 36 ) of the guide profiles ( 30 ).

4. The wiper blade ( 10 ) as claimed in claim 3 , characterized in that the retention elements are in the form of attachment profiles ( 58 ) for the adjoining spoiler parts ( 22 , 24 ).

5. The wiper blade ( 10 ) as claimed in claim 4 , characterized in that the attachment profiles ( 58 ) form, with transition profiles ( 56 ) and the connecting strip ( 54 ), a connecting piece ( 52 ) which at least partially covers the attachment element ( 18 ).

6. The wiper blade ( 10 ) as claimed in claim 1 , characterized in that top sides of the guiding ribs ( 32 , 34 , 40 ) terminate flush with top sides of the guide profiles ( 30 ).

7. The wiper blade ( 10 ) as claimed in claim 1 , wherein the guide profile ( 30 ) extends laterally outwardly farther along the flow-off side ( 28 ) than along an opposite, flow-impingement side ( 26 ).

8. The wiper blade ( 10 ) as claimed in claim 1 , wherein the carrier element ( 14 ) is an elongated element that extends in an elongate direction along an axis, and wherein the plane includes the axis.

9. A wiper blade ( 10 ) of flat bar construction, having a wiper strip ( 12 ) which is held by a band-like, resiliently elastic carrier element ( 14 ) which is pre-curved in a concave manner with respect to a wiper lip ( 16 ) of the wiper strip ( 12 ), wherein one or more spoiler parts ( 22 , 23 ) are mounted by means of guide profiles ( 30 ) on a side of the carrier element ( 14 ) which faces away from the wiper lip ( 16 ), which spoiler parts enclose the carrier element ( 14 ) from outer longitudinal sides and protrude to a small extent beyond a flow-off side ( 26 ) of the spoiler part ( 22 , 23 ) and form, with said flow-off side, a fillet ( 31 ), wherein an attachment element ( 18 , 64 ) for the articulated connection of a wiper arm is fastened in a central region of the wiper blade ( 10 ), characterized in that the guide profile ( 30 ) on the flow-off side ( 28 ) has, on an outwardly pointing longitudinal side of the guide profile, a guiding rib ( 32 , 34 , 40 ), and wherein, in a region ( 36 ) extending over the attachment element ( 18 ), a connecting piece ( 52 ) forms, by way of a connecting strip ( 54 , 60 ), a guiding rib ( 40 ) which, in a longitudinal direction to both sides of the attachment element ( 18 ), and by way of retention elements ( 58 , 62 ), is hooked onto the one or more spoiler parts ( 22 , 24 ) and adjoins the associated guide profiles ( 30 ) or the guiding ribs ( 34 , 36 ) of the guide profiles ( 30 ).

10. The wiper blade ( 10 ) as claimed in claim 9 , wherein the retention elements are in the form of attachment profiles ( 58 ) for the adjoining spoiler parts ( 22 , 24 ).

11. The wiper blade ( 10 ) as claimed in claim 10 , wherein the attachment profiles ( 58 ) form, with transition profiles ( 56 ) and the connecting strip ( 54 ), a connecting piece ( 52 ) which at least partially covers the attachment element ( 18 ).

12. The wiper blade ( 10 ) as claimed in claim 9 , including two spoiler parts ( 22 , 24 ), of which an inner spoiler part ( 22 ) extends from an inner end of the wiper blade ( 10 ) to the attachment element ( 18 , 64 ) whereas an outer spoiler part ( 24 ) extends from an outer end of the wiper blade ( 10 ) to the attachment element ( 18 , 64 ), wherein one or both spoiler parts ( 22 , 24 ) has a guide profile ( 30 ) with a guiding rib ( 32 or 34 respectively).

13. The wiper blade ( 10 ) as claimed in claim 9 , wherein top sides of the guiding ribs ( 32 , 34 , 40 ) terminate flush with top sides of the guide profiles ( 30 ).
