Problems solved by technology

Although a spoiler element of said type such as is known from practice exhibits desirable features with regard to its action, its fastening to the wiper arm on the side opposite to the wiper blade has the effect that the structural height is increased, This can result in the driver's view being blocked
Furthermore, arrangements of the type described also exhibit increased air resistance

Embodiment Construction

[0037] Identical elements or elements of the same function are indicated in the figures by the same reference numerals.

[0038] In perspective view, figure 1 A wiper device 100 is shown for cleaning vehicle windows (not shown), in particular the front window of a vehicle. The wiper device 100 has a wiper blade 1 in particular in the form of a so-called flat wiper blade. The wiper blade 1 is fastened interchangeably to the wiper arm 10 . The wiper arm 10 comprises an elongated wiper arm 11 which is constructed of metal or plastic and serves as a support element and is passed through a pin 12 and a sleeve 13 ( figure 2 ) is pivotally fastened to the wiper arm head 14, which in particular consists of aluminum (alternatively plastic). The wiper arm head 14 has a through opening 15 on the side turned away from the wiper arm shaft 11 for fastening the wiper arm head 14 rotationally coupled to a wiper shaft (not shown), which at least indirectly ground to the wiper support or w...

Abstract

The invention relates to a wiper arm (10; 10a - 10d) for cleaning a vehicle window, with a carrier element (11), which is able to be connected at a first end region at least indirectly with a drive shaft and at another end region with a wiper blade (1), and with an additional element (30) connected with the carrier element (11), which additional element (30) extends in longitudinal direction of the wiper arm. It is provided according to the invention that the additional element (30) has at least one air guide section (166, 167), extending in longitudinal direction of the wiper arm (10; 10a - 10d), which at least one air guide section (166, 167) projects beyond the underside (168) of the carrier element (11) on the side facing the vehicle window.

Description

technical field [0001] The invention relates to a wiper device for cleaning vehicle windows. The wiper device has a wiper arm with a substantially U-shaped cross-section comprising a top side and two side walls, which can be at least indirectly connected to a drive at a first end region. The shaft is connected and is connected to the wiper blade at the other end region; and there is an additional element connected to the wiper arm rod, which extends in the longitudinal direction of the wiper arm. Background technique [0002] Wiper arms of the type known from practice have, for example, a carrier element in the form of a wiper arm rod, on whose top side a spoiler element is arranged. The spoiler element—consisting, for example, of plastic—is used to increase the contact pressure on the wiper blade connected to the wiper arm, especially at relatively high speeds, so that even at relatively high speeds, the wiper blade Lifting from vehicle windows is avoided. In particular,...
