Pivotal coupling for wiper arm and blade

A device pivotally connecting a wiper blade (12) for motor vehicle windows (10) to a wiper arm (14), which is guided on a vehicle and can be moved between reversal points, which has two side walls (32), which are disposed parallel to and spaced apart from each other in a movement direction and extend toward the window, which are respectively penetrated by support bores (34) that share a common longitudinal axis (26) with an elongated rubber elastic wiper strip (20), which can be placed with a wiper lip (18) against the window (10) to be wiped and is secured by a band-shaped, elongated, spring elastic support element (40), and with two pivot pins (62) belonging to the pivotal connection, which are aligned lateral to the longitudinal span of the support element and are each guided in one of the two support bores (34), characterized in that on each of its longitudinal sides the wiper strip (20) has a longitudinal receiving groove (36) for a respective longitudinal strip (88) of the support element (40), each of which strips protrude with an edge strip (50) out of this receiving groove at least over a longitudinal section, that each edge strip is secured by a securing element (54), and that each of the two pivot pins (62) is disposed on a mutually remote longitudinal side of each of two securing elements.
