Abstract

The invention is based on a wiper arm (10) for a windshield wiper, having a fastening part (12) and a joint member (18) that are connected to one another via a swing-down joint (54), and a tension spring (26) is suspended by one end (28) from a suspension device (24) of the joint member (18) and by its other end (30) via a C-shaped bracket (32) in a suspension device (16) of the fastening part (12) and in an operating position presses a wiper blade (34), via a wiper rod (22), against a windshield and in a swing-down position presses a contact face of the joint member (18) or of the C-shaped bracket (32) against a limiting stop of the fastening part (12). It is proposed that between the operating position and the swing-down position, a detent position is provided, up to which the wiper blade (34) can be raised from the windshield in a parking position, without touching a hood over the engine.
