Abstract:
1. Windshield wiper arm ( 10 ) having a wiper arm for attaching a wiper blade ( 6 ) with or without a spoiler, characterized in that, the wiper rod ( 41 ) is comprised of a freely projecting, first arc-shaped wiper rod section ( 1 ) with a first curvature progression, to which the wiper blade ( 6 ) is attachable, and of at least one second arc-shaped wiper rod section ( 2 ) curved along its length with a second arc-shaped curvature progression, which directly adjoins the first wiper rod section ( 1 ) to form a first flexion point ( 12 ), characterized in that, the second arc-shaped wiper rod section ( 2 ) is bent back on one side into a bent back arc-shaped wiper rod section ( 3 ) as a two-spoke dual spring system, in which, in an applied state of the wiper arm, the bent-back wiper rod section ( 3 ) is curved along its length and runs in a layer plane above or below a positional plane of the second arc-shaped wiper rod section ( 2 ) essentially congruent to the second arc-shaped wiper rod section ( 2 ) as well as with approximately the same curvature progression as said second wiper rod section along a presentable longitudinal section, a tangential extension of the first arc-shaped wiper rod section ( 1 ) and a tangential extension of the second arc-shaped wiper rod section ( 2 ) enclose an angle ( 11 ) of between 90° and 180°, in area of the flexion point ( 12 ) as viewed from a side opposite from a wiping edge of the wiper blade ( 6 ).
