A wiper arm and a windscreen wiper system, wherein the wiper arm comprises a joint part and a lever part and a spring, wherein the parts form a common joint. The spring is embodied here as a torsion spring.

A wiper system for clearing an outer surface of a window is disclosed and includes an arm, a frame, a blade, and an actuator operatively connected to the arm. The arm includes a parked position and defines a proximate end portion and a distal end portion. The arm is pivotable about the proximate end portion of the arm out of the parked position. The frame is pivotally connected to the distal end portion of the arm. The frame defines a lengthwise distance. The blade extends along at least a lengthwise portion of the frame. The blade defines an edge that is configured to contact the outer surface of the window when the arm is in the parked position. The actuator is configured to exert a force against the arm that is sufficient to urge the arm out of the parked position and away from the outer surface of the window.

The invention relates to a windshield wiper device (100) for a vehicle having a fastening element (52), in particular a motor vehicle. The windshield wiper device (100) comprises a mounting element (40), which is designed to be mounted on the fastening element (52), and a wiper blade (2) having an elongated upper part (10) and an elongated lower part (12), which parts are at least partially flexible. Furthermore, a plurality of connection elements (18) for connecting the upper part (10) and the lower part (12) are provided, wherein the connection elements (18) are spaced apart from one another along a longitudinal extension (8) of the wiper blade (2). The connection elements (18) are configured to allow a movement of the upper part (10) and the lower part (12) relative to one another with a motion component along a longitudinal extension (8) of the wiper blade (2). The wiper blade (2) further comprises a fastening part (20) on the wiper-blade side. The fastening part (20) on the wiper-blade side is configured such that by means of a movement of the fastening part (20) on the wiper-blade side relative to the mounting element (50), a first engagement can be formed in order to connect the fastening part (20) on the wiper-blade side to the mounting element (50). The windshield wiper device (100) further comprises a closure mechanism (52, 22), which is configured to fix a position of the fastening part (20) on the wiper-blade side relative to the mounting element (50) after the first engagement has been formed.

The invention relates to a windshield wiper device for a vehicle, in particular a motor vehicle, having a fastening element fastened to a drive shaft. The windshield wiper device comprises a wiper blade having an elongate upper part, which is at least partially flexible, an elongated lower part, which is at least partially flexible, and a plurality of connecting elements for connecting the upper part and the lower part. Along a longitudinal extension of the wiper blade, the connecting elements are spaced apart from one another, wherein the connecting elements are designed to allow a movement of the upper part and the lower part relative to one another, by means of a movement component, along a longitudinal extension of the wiper blade.
