Windshield wiper
First Claim
1. A windshield wiper mechanism including an arm head adapted to be rotatably connected to a stationary part of a vehicle, a main arm having one end rotatively supported on the arm head for rotation around a first axis of rotation and adapted to have a wiper blade mounted on the other end thereof, a sub-arm having a wing supported thereon and being rotatively supported on said arm head for rotation around a second axis of rotation, said wing having a surface defining a plane, said sub-arm overlying and abutting said main arm so that the second axis of rotation defines with respect to the first axis of rotation an acute angle positioned such that with respect to the plane of the wing part of the force of air acting on the wing as a vehicle on which said wiper mechanism is mounted moves through air is transmitted to the main arm.

Abstract
A windshield wiper including an arm head rotatably connected to a stationary part of a vehicle, a main arm rotatively supported on the arm head and having a wiper blade thereon, and a sub-arm supporting a wing and being rotatively supported on the arm head. The axis of the rotative movement of the sub-arm and that of the main arm make an acute angle therebetween whereby a part of the air force acting on the wing is transmitted to the main arm as determined by a partial force defined by the acute angle.
