Abstract
A wiper apparatus has a wiper blade which has a multi-linked frame on which a wiping element placed on the windshield is held and wherein the frame has an upper bow of an essentially U-shaped cross section, on at least one end of which a lower bow, which dips between the U-shaped legs, is hinged in the manner of a balance arm, and wherein an elastically deformable hinge element, which can be locked with the upper bow and is U-shaped at least in the installed state, is disposed between the surfaces of the upper and lower bows facing each other, and extends with hinge protrusions disposed on the insides of its U-shaped legs and oriented toward each other into bearing recesses of the lower bow. A particularly simple and low-cost assembly is achieved, if the upper bow has at least one opening in the area of its U-shaped base, through which a detent element connected with the hinge element lockingly extends while being elastically deflected in respect to the upper bow.
