Wiper arm (1) with pantograph dynamic action, comprising a main rod (2a) and a secondary rod (2b),;characterized in that of the said main rod (2a) and secondary rod (2b) each comprises a negative lift surface profile the cross section of which is delimited by an upper side (25a, 25b), a lower side (26a, 26b), and, in the direction of the air flow, an anterior edge (23a, 23b) referred to as the leading edge and a posterior edge (24a, 24b) referred to as the trailing edge opposite the leading edge (23a, 23b),
and in that, in the position as mounted on a vehicle, the arm (1) is positioned with respect to the vehicle surface that is to be wiped in such a way that the said lower sides (26a, 26b) of the cross sections of the rods (2a, 2b) face towards the surface that is to be wiped, so as to press the arm (1) more firmly against the surface that is to be wiped. |
