Wiper blade for motor vehicle windows, with support element, wiper strip and connection device for a driven wiper arm
First Claim
1. A wiper blade for motor vehicle windows, comprising an elongated spring-elastic support element;
- an elongated, rubber elastic wiper strip which is pressable against a window to be wiped and is held substantially parallel to a longitudinal axis by said elongated, spring-elastic support element;
a connection device for a driven wiper arm, said connection device being loadable toward the window and secured to a middle portion of said spring-elastic support element, remote from the window, said connection device being formed as a component which is separate from said support element; and
a welding connection which connects said connection device with said support element, said support element being band-shaped, said connecting device having a substantially U-shaped transverse cross-section with legs joined by a base, said connecting device arresting with said base flatly on a side remote from the window of said band-shaped support element, said base of said connection device being provided, on its side remote from said legs with protrusions, which are spaced apart from one another crosswise to a longitudinal extent of said support element by a distance which is adapted to a width of said support element.

Abstract
A wiper blade (10) is proposed that is used to clean windows (26) of motor vehicles. The wiper blade (10) has an elongated, rubber-elastic wiper strip (14), which can be pressed against the window (26) to be wiped and is held substantially parallel to the longitudinal axis on an elongated, spring-elastic support element (12), to whose middle portion, remote from the window (26), a connection device (16) for counterpart connection means of a driven wiper arm, which means can be loaded toward the window (26), are disposed. Problem-free, economical disposition of the connection device (16) on the support element (12) is obtained if the connection device is embodied as a separate component and secured to the support element by means of a welded connection.
