The invention relates to a four-hinged wiper arm for a windshield wiper system, especially for an automobile wherein a connecting rod is pivotally connected to a driving arm in a first bearing point and to a control arm in a second bearing point. A hinged part is coupled to the connecting rod. A wiper blade that can be placed on the hinged part or on a wiper rod connected to the hinged part can be pressed against the windshield to be wiped by a spring element that is mounted on the four-hinged wiper arm.
