Abstract The invention relates to a windshield wiper device (100, 200, 300) for a vehicle, in particular a motor vehicle, comprising a wiper blade (2) having an elongate upper part (10), which is at least partially flexible, an elongate lower part (12), which is at least partially flexible, a plurality of connecting elements (18) for connecting the upper part (10) and the lower part (12), wherein the connecting elements (18) are spaced apart from each other along a longitudinal extent (8) of the wiper blade (2) and are attached to the upper part (10) and/or to the lower part (12) by means of a rotary joint, in particular wherein the connecting elements (18) are designed to enable a motion of the upper part (10) and of the lower part (12) relative to each other having a motion component along the longitudinal extent (8) of the wiper blade (2), and a spoiler (110, 210, 310, 410), which is arranged on the elongate upper part (10). ## Claims ### Claim 1 A windshield wiper device (100, 200, 300) for a vehicle, comprising a wiper blade (2) having an elongate upper part (10) which is configured in an at least partially flexible manner, an elongate lower part (12) which is configured in an at least partially flexible manner, a plurality of connecting elements (18) for connecting the upper part (10) and the lower part (12), wherein the connecting elements (18) are spaced apart from one another along a longitudinal extent (8) of the wiper blade (2) and are attached to the upper part (10) and/or to the lower part (12) by a rotary joint (20), and a spoiler (110, 210, 310, 410) which is arranged on the elongate upper part (10). ### Claim 2 (depends on 1) The windshield wiper device (100) as claimed in claim 1, wherein the spoiler (110) has a cross section substantially perpendicular to the longitudinal extent (8) and wherein the cross section is asymmetric. ### Claim 3 (depends on 1) The windshield wiper device (200) as claimed in claim 1, wherein the spoiler (210) has a cross section substantially perpendicular to the longitudinal extent (8) and wherein the cross section is symmetric. ### Claim 4 (depends on 1) The windshield wiper device (100, 200, 300) as claimed in claim 1, wherein the spoiler (110, 210, 310, 410) has a cross section substantially perpendicular to the longitudinal extent (8) and wherein the cross section changes along the longitudinal extent (8). ### Claim 5 (depends on 1) The windshield wiper device (100, 200, 300) as claimed in claim 1, wherein the spoiler (110, 210, 310, 410) extends along at least a part of a length of the wiper blade (2) in the longitudinal extent (8). ### Claim 6 (depends on 1) The windshield wiper device as claimed in claim 1, wherein the spoiler (410) has two or more segments (412) which are arranged on the upper part (10) such that the spoiler (410) is flexible. ### Claim 7 (depends on 6) The windshield wiper device as claimed in claim 6, wherein the two or more segments (412) are arranged in a manner spaced apart from one another. ### Claim 8 (depends on 1) The windshield wiper device (100, 200, 300) as claimed in claim 1, wherein the spoiler (110, 210, 310, 410) is formed from hard plastic. ### Claim 9 (depends on 1) The windshield wiper device (300) as claimed in claim 1, further comprising a wiper-blade-side fastening part (310) configured to be connected to a fastening element on the vehicle. ### Claim 10 (depends on 9) The windshield wiper device (300) as claimed in claim 9, further comprising an adapter device (350) which is configured as an interface between the wiper-blade-side fastening part (310) and the fastening element on the vehicle or a wiper arm. ### Claim 11 (canceled) ### Claim 12 (depends on 1) A method for producing a windshield wiper device as claimed in claim 1, the method comprising forming the spoiler on the upper part by injection-molding. ### Claim 13 (depends on 1) The windshield wiper device (100) as claimed in claim 1, wherein the connecting elements (18) are configured to allow a movement of the upper part (10) and of the lower part (12) relative to one another with a movement component along the longitudinal extent (8) of the wiper blade (2), ### Claim 14 (depends on 1) The windshield wiper device (100, 200, 300) as claimed in claim 1, wherein the spoiler (110, 210, 310, 410) extends along at least 50% of a length of the wiper blade (2) in the longitudinal extent (8). ### Claim 15 (depends on 1) The windshield wiper device (100, 200, 300) as claimed in claim 1, wherein the spoiler (110, 210, 310, 410) extends along at least 80% of a length of the wiper blade (2) in the longitudinal extent (8). ### Claim 16 (depends on 1) The windshield wiper device (100, 200, 300) as claimed in claim 1, wherein the spoiler (110, 210, 310, 410) extends along at least 100% of a length of the wiper blade (2) in the longitudinal extent (8). ### Claim 17 (depends on 1) The windshield wiper device (100, 200, 300) as claimed in claim 1, wherein the spoiler (110, 210, 310, 410) is formed from thermoplastic or thermosetting plastic.
