Patent ID: 6857160

Claim:
A windshield wiper device, comprising: a wiper arm ( 10 , 30 ) that is drivable by means of a drive, wherein said wiper arm ( 10 , 30 ) is able to be folded against a windshield and is able to be folded away from the windshield, wherein a wiper blade is arranged on the wiper arm, wherein the wiper arm ( 10 , 30 ) has a first region ( 11 ) that faces the drive and a second region ( 12 ) that faces the wiper blade, wherein the first region ( 11 ) of the wiper arm ( 10 , 30 ) facing the drive and the second region ( 12 ) of the wiper arm ( 10 , 30 ) facing the wiper blade are connected with two torsion spring elements ( 13 , 14 , 21 , 22 , 41 , 42 , 51 , 52 , 61 , 62 , 71 , 72 ), and wherein the torsion spring elements are inserted in the first region ( 11 ) and second region ( 11 ) of the wiper arm ( 10 , 30 ), whereby the torsion spring elements ( 13 , 14 , 21 , 22 , 41 , 42 , 51 , 52 , 61 , 62 , 71 , 72 ) are provided with torsion angles that are opposed to one another and the torsion spring elements ( 13 , 14 , 21 , 22 , 41 , 42 , 51 , 52 , 61 , 62 , 71 , 72 ) have a rectangular cross section, whose width is greater than its thickness, so that the torsion spring elements ( 13 , 14 , 21 , 22 , 41 , 42 , 51 , 52 , 61 , 62 , 71 , 72 ) are curved in toward the windshield or curved away from the windshield, wherein one connecting element ( 53 , 63 ) is formed in one piece and another connecting element is formed in two pieces, and wherein, in a pre-assembled state, the two torsion spring elements ( 51 , 52 , 61 , 62 ) are arranged with a first end in a V-shape at the one-piece connecting element ( 53 , 63 ) and wherein a part ( 54 , 55 , 54 , 66 ) of the two-piece connecting element is mounted on a second end of the torsion spring elements ( 51 , 52 , 61 , 62 ).
