Abstract

A wiper blade (10) is proposed, which is used for cleaning windows (20) of motor vehicles. The wiper blade can be connected by coupling means to counter-coupling means on the wiper arm side of a driven wiper arm (18) provided on the motor vehicle. Its coupling means are placed in the center section of a strip-like, elongated, spring-elastic support element (12) of the wiper blade, on the side of which facing the window to be wiped an elongated, rubber-elastic wiping strip (14), which can be placed against the window, is arranged essentially parallel with the longitudinal axis, and the wiper blade, which can be displaced transversely in respect to its longitudinal direction on the window, is pivotable in respect to the wiper arm around an axis (40) extending in the displacement direction. A particularly low structural height of the wiper blade is achieved if the support element (12) is made of a metal, if moreover the distance of the plane of displacement of the pivot axis (40) from the surface (22) of the window (20) to be wiped is at most as great as the distance (44) between this surface (22) and the strip surface (11) of the support element (12) facing away from the window.

Claims

1. A wiper blade (10) for windows of motor vehicles, which can be connected by coupling means on a wiper blade side to counter-coupling means of a driven wiper arm (18) provided on the motor vehicle, wherein the coupling means on the wiper blade side are placed in a center section of a strip-shaped, elongated, spring-elastic support element (12) of the wiper blade (10), on a side of which facing the window (20) to be wiped an elongated, rubber-elastic wiping strip (14), which can be placed against the window, is arranged essentially parallel with a longitudinal axis, and the wiper blade, which can be displaced transversely in respect to its longitudinal direction on the window (20), is pivotable in respect to the wiper arm (18) around a pivot axis (40) extending in a displacement direction (42), said pivot axis being constituted by a common longitudinal axis of two pins (38), said pins are arranged opposite each other on the support element (12) and project past the longitudinal edges of the latter, said pins are arranged on a separate component (30), which is part of the support element (12) and is fixedly connected with the support element (12), the support element (12) is made of a metal, and a distance (46) of a plane of displacement of the pivot axis (40) from a surface (22) of the window (20) to be wiped is at most as great as a distance (44) between this surface (22) and a strip surface (11) of the support element(12) extending over a length of the support element (12) and facing away from the window (20).

2. The wiper blade in accordance with claim 1, characterized in that the component (30) is made of a plastic material and that the pins (38) are formed in one piece on it.

3. The wiper blade in accordance with one of claims 1, characterized in that a bearing receptacle (50) provided on the wiper arm (18) is assigned to each of the pins (38).

4. A wiper blade (10) for windows of motor vehicles, which can be connected by coupling means on a wiper blade side to counter-coupling means of a driven wiper arm (18) provided on the motor vehicle, wherein the coupling means on the wiper blade side are placed in a center section of a strip-shaped, elongated, spring-elastic support element (12) of the wiper blade (10), on a side of which facing the window (20) to be wiped an elongated, rubber-elastic wiping strip (14), which can be placed against the window, is arranged essentially parallel with a longitudinal axis, and the wiper blade, which can be displaced transversely in respect to its longitudinal direction on the window (20), is pivotable in respect to the wiper arm (18) around an axis (40) extending in a displacement direction (42), the support element (12) is made of a metal, and a distance (46) of a plane of displacement of the pivot axis (40) from a surface (22) of a window (20) to be wiped is at most as great as a distance (44) between this surface (22) and a strip surface (11) of the support element (12) facing away from the window (20), and a component (30) is designed U-shaped in cross-section, its base (36) rests with its inside against an upper strip surface (11) of the support element (12) facing away from the window (20), wherein legs (34) respectively project past a longitudinal edge (32) of the support element (12), and a pin (38) is arranged on outsides, facing away from each other, of each leg (34).
