Abstract

The invention is based on a wiper arm (10), with a pivotably connected wiper blade (16), which includes at least one bracket (18,20,22) and a wiper strip (26) and which is guided laterally in relation to the wiper arm (10) by a device (32,44,58). A first part (34,48,62) of the device (32,44,58) associated with the wiper arm (10) is connected to a second part (36,46) associated with the wiper blade (16) by means of a link (38,50,60), which flexes approximately perpendicular to the windshield (30). The invention proposes that the second part (36,46) be permanently connected to the wiper blade (16).

Claims

1. A wiper arm (10), in combination with a pivotably connected wiper blade (16), said blade includes at least one bracket (18, 20, 22) and a wiper strip (26) and is guided laterally in relation to the wiper arm (10) by a device (32, 44, 58), wherein a first part (34, 48, 62) of the device (32, 44, 58) associated with the wiper arm (10) has guide surfaces, wherein said guide surfaces rest laterally against the wiper arm or engage in a guide profile (54) of the wiper arm, wherein the guide surfaces permit a movement in a longitudinal direction of the wiper arm and perpendicular to a vehicle windshield, wherein a second part (36, 46) of the device (32, 44, 58) is permanently connected with the wiper blade, wherein the first part is connected to the second part (36, 46) by means of a link (38, 50, 60), wherein the link flexes approximately perpendicular to a vehicle windshield (30), wherein the link is a leaf spring, and wherein the guide surfaces (42) have ribs (56) extending in a stroke direction (40).

2. The combination according to claim 1, wherein the device (32, 44, 58) is formed onto a part (36) of the bracket (18, 20) or a cap (46) of the wiper strip (26).

3. The combination according to claim 1, wherein the leaf spring (38, 50, 60) is disposed at an end of the guide surfaces (42) oriented toward the vehicle windshield (30).

4. The combination according to claim 1, wherein the wiper arm has projections (52) extending in the stroke direction (40) in a vicinity of the guide surfaces (42).

5. The combination according to claim 1, wherein the link (38, 50, 60) is disposed on a top, on a side, or in an extension of the wiper blade (16).
