1. Windshield wiper device (10), comprising at least one wiper bearing (14) including a bearing housing (24);
- a wiper shaft (22) that is mounted in the bearing housing (24) and can bear a wiper arm on a first end (26); and
an element (40) that axially supports the wiper shaft (22), characterized in that the element (40) is embodied as a bridging element including first, second and third planar components (42, 44, 46) spaced along an axis of the wiper shaft (22), a first plurality of connecting pieces (48) extending between the first planar component (42) and the second planar component (44), and a second plurality of connecting pieces (48) extending between the second planar component (44) and the third planar component (46), wherein the second plurality of connecting pieces (48) are offset from the first plurality of connecting pieces (48), characterized in that the bridging element (40) has at least one predetermined breaking point (52), and characterized in that at least one predetermined breaking point (52) is provided in at least one planar component (42, 44, 46), and wherein the at least one predetermined breaking point (52) comprises a reduction in a resistance cross-section of the at least one planar component (42, 44, 46).

Abstract
A windscreen wiper device (10), in particular for a motor vehicle, comprises at least one wiper bearing (14) provided with a bearing housing (24). The wiper shaft (22) mounted in the bearing housing (24) can move a wiper arm to a first end (26). The inventive device also comprises an element (40) which axially supports the wiper shaft (22). According to said invention, the element (40) is embodied in the form of a bridging element.
