Embodiment Construction

[0030] figure 1 The wiper arm according to the invention is shown in a side view in the maintenance position. The wiper arm essentially consists of a hinged part 1 , which is connected at one end in a rotationally movable manner to a fastening part 2 and is in a folded-out position relative to the fastening part 2 . A spring element (not shown) is arranged between the hinge part 1 and the fixing element 2 . The hinge part 1 is substantially in the form of a U-shaped profile part 3 in cross section, which consists of a back part 4 and two side wall parts 5 and 6 . The hinge part 1 partially surrounds the fastening part 2 .

[0031] figure 2 The wiper arm articulation of the wiper arm according to the invention in the maintenance position is shown in side view. In the side wall part 6 of the hinge part 1 there is provided a bearing opening 8 for receiving the hinge pin 7 which is arranged on the fastening part 2 . The hinge pin 7 is locked in the bearing region 9 of the be...

Abstract

The invention relates to a wiper arm, in particular for a window wiper device of a motor vehicle, with a hinge part (1) which is connected rotatably at one end to a fastening part (2), and with at least one spring element acting between the hinge part (1) and the fastening element (2), wherein the hinge part (1) is pivotable in relation to the fastening part (2) from a working position into a service position, and vice versa, wherein the hinge part (1) is designed as a substantially U-shaped profile (3) which consists of a back (4) and two side members (5, 6) and at least partially engages around the fastening part (2), wherein the fastening part (2) has at least one hinge pin (7), wherein a bearing opening (8) for receiving a hinge pin (7) is provided at least in one side member (5, 6) of the hinge part (1), wherein the hinge pin (7) is secured in a bearing region (9) of the bearing opening (8) by means of the spring force of the spring element, wherein the bearing opening (8) is substantially U-shaped and has an outwardly facing recess (11) in the lower limb (10) of the bearing region (9).

Description

technical field [0001] The invention relates to a wiper arm, in particular to a wiper arm of a windshield wiper device. Background technique [0002] Wiper arms of this type are known in large numbers. They have a fastening part on which the joint part is rotatably mounted via a wiper arm joint. A wiper blade is fixed at the other end of the hinge. [0003] Such a wiper arm is described in DE 10126258 A1. The wiper arm described there has on its fastening part a u-shaped bearing opening for receiving a joint pin arranged on the joint part. [0004] Constructions are also known in which a u-shaped bearing opening is provided in the joint part and the fixing part has a joint pin which is guided in the u-shaped bearing opening. [0005] Generally, the hinged part and the fastening part are tensioned by means of spring elements, whereby the hinged pin in the operating position is drawn into the U-shaped bearing opening and at the same time a sufficiently high pressing force ...
