Abstract: A wiper apparatus includes a wiper axis interface (102) configured for mounting a wiper assembly to a wiper drive (106). A lower wiper arm (110) extends from the wiper axis interface to a wiper mount (112) that is configured to connect the lower arm to an upper arm (114). A first end (124) of the lower wiper arm proximate the wiper axis interface has a first airfoil profile and wall thickness. A second end (126) of the lower wiper arm proximate the wiper mount has a second airfoil profile and wall thickness. An intermediate portion (128) of the lower wiper arm extending between the first and second ends has a transitioning airfoil profile and thickness that transitions from the first airfoil profile and wall thickness to the second airfoil profile and wall thickness.
