Problems solved by technology

A correspondingly adapted end cap must therefore be produced for each application, which would be cost-intensive starting from the production plant of the end cap through to inventory and even the risk of confusion during assembly

Embodiment Construction

[0032] The wiper blade 10 for motor vehicle windshields shown in FIGS. 1 and 2 has a longitudinally extending, spring-loaded support part 14 . On the upper side 15 of the carrier 14 facing away from the glass 12 to be wiped, a wiper blade-side half 16 of a connecting device 18 is mounted, by means of which the wiper blade 10 can be connected to a guide on the motor vehicle body. The ground-driven wiper arm 20 , indicated by a dotted line in FIG. 1 , forms a detachable connection. A rubber-mounted wiper strip 22 extending longitudinally relative to the support part parallel to its longitudinal axis is mounted on the lower side 21 of the support part 14 facing the glass 12 . The wiper arm 20 and thus the wiper blade 10 act in the direction of the arrow 24 on the glass to be wiped, the surface of which is indicated by the dotted line 26 in FIG. 1 . Since this dotted line 26 represents the maximum curvature of the vehicle glass surface, it can be clearly seen that the curvature o...

Abstract

The invention relates to wiper blades of various dimensions for windows of motor vehicles, with band-like, elongated, spring-elastic support elements (14), each for a respective wiper strip (22), which is associated with each wiper blade (10), can be placed against the window (12), and is disposed on the lower band surface (21) oriented toward the window, where in a longitudinal midsection of each support element, the upper band surface (15) oriented away from the window supports a wiper blade half (16) of a connecting device (18). In order to supply wiper blades of different dimensions with a single type of such a connecting device half and to thereby reduce the costs for the wiper blades, the widths (36) of the support elements in this longitudinal midsection are the same size independent of the other dimensions of these support elements.

Description

technical field [0001] The invention relates to a wiper blade for motor vehicle windows. Background technique [0002] When designing a wiper blade, it is necessary to take into account several criteria specified by regulations and vehicle manufacturers, such as the area of ​​the glass swept by the wiper blade, the size of the glass, the curvature of the glass, the pressure of the wiper blade on the glass, the air in front of the glass air distribution. For obvious reasons, all this leads to the fact that in practically every motor vehicle model and also for the wiper blades on the driver's side and the front passenger's side, it is necessary to use a support completely dedicated to the wiper strip contacting the glass. The carrier must be provided with a wiper blade-side connecting device half, via which the wiper blade can be connected to the wiper arm on which the other half is mounted. [0003] In order to be able to comply with the regulations imposed by the motor veh...
