Wiper blade for the glass surfaces of a motor vehicle
DCFirst Claim
1. A wiper blade for cleaning motor vehicle windows and glass, having an elongated, rubber-elastic wiper strip (16) that can be pressed against the window and glass (24) and that is disposed, parallel to a longitudinal axis, on one band face (14) of a band-shaped-elongated, spring-elastic support element (12), and a coupling part (20) connected to a center portion of the support element is seated on another band face (18) of the support element and has one hinge half, whose hinge axis (52) is oriented transversely to a length of the wiper blade (10), wherein both this hinge half and coupling means of the wiper blade are formed by a bearing recess (36) in the coupling part (20), and the coupling part (20) is considerably shallower over a longitudinal portion than a longitudinal region of the bearing recess (36), and wherein the longitudinal portion (50) is formed by a width of a transverse groove (54).

Abstract
A wiper blade is proposed, which is used for cleaning motor vehicle windows or glass. The wiper blade (10) is provided with an elongated, rubber-elastic wiper strip (16) that can be pressed against the window or glass (24) and that is disposed, parallel to the longitudinal axis, on one band face (14) of a bandlike-elongated, spring-elastic support element (12), and a coupling part (20) connected to the center portion of the support element is seated on the other band face (18) of the support element and has one hinge half (36), whose hinge axis (52) is oriented transversely to the length of the wiper blade (10). An improvement in wiper blade mounting and in the securing of the mounted wiper blade to a wiper arm provided with a hinge bolt is attained, if both this hinge half and the coupling means of the wiper blade are formed by a bearing recess (36) in the coupling part (20).
