Wiper blade for motor vehicle windows
DC CAFC
First Claim
1. A wiper blade for a wiping device of a motor vehicle for wiping a window of the motor vehicle, comprising an elongated wiper strip placeable against the window, and an elongated spring-elastic carrying element disposed on a side of the wiper strip remote from the window, said spring-elastic carrying element extending parallel to an axis of elongation of said wiper strip to distribute a contact force against the window over an entire length of said wiper strip, said wiper strip having a center section and two end sections, said contact force of said wiper strip being greater in said center section than in at least one of said two end sections, said spring-elastic carrying element has on a side thereof oriented toward the window a concave curvature that is sharper than the sharpest curvature of a spherically curved window in a region of a wiping field that can be swept across by said wiper blade and a concave curvature in said center section of the carrying element is sharper than in said sections thereof.

Abstract
A wiper device with a wiper blade for cleaning windows of motor vehicles, in which the wiper blade can be moved back and forth laterally to its longitudinal span by a driven wipe arm which can be connected to the wiper blade and loads the same against the window. The wiper blade has an elongated wiper strip that can be placed against the window and an elongated spring-elastic carrying element, which has a connecting unit for the wiper arm and is disposed parallel to the longitudinal axis of the wiper strip to distribute a contact force over the entire wiper strip length. A particularly effective and low-noise operation of the wiper system is achieved because the contact force of the wiper strip against the window is greater in its center section than in at least one of two end sections of the wiper strip.
