Abstract
A device for pivotally connecting a wiper blade (12) for motor vehicle windows (10) to a wiper arm (14) which can be moved between reversal positions and is guided on the vehicle. On its free end section, the wiper arm (14) is provided with a pivot bolt extending essentially in the movement direction for connecting an elongated wiper blade, which has an elongated elastic support element (22) whose underside oriented toward the window has a wiper strip (20) disposed on it, which can be placed against the window (10), and the support element is provided with a transverse bore (68) that is open toward its top, whose opening width constitutes a narrow point (72) that is narrower than the bore diameter, wherein the edge regions of the narrow point can be elastically spread open to the size of the bore diameter. The particular demands on the support and on the transverse bore or the narrow point in order to connect the wiper arm are taken into consideration if the support element has at least one band-like, elongated, spring-elastic support strip for holding the wiper strip (20), whose top (37) remote from the window (10) has a coupling element (46) disposed on it, which is made of an el…
