1. A wiper blade assembly, comprising:
- a wiper blade member having a length; and
an airfoil member operatively connected to the wiper blade member, the airfoil member extending longitudinally along at least a portion of the wiper blade member length, the airfoil member having a cross-sectional profile that is symmetrical about a plane of symmetry extending through a center of the airfoil member and longitudinally through the airfoil member.

Abstract
A wiper blade assembly includes a wiper blade member and an airfoil member operatively connected to the wiper blade member. The airfoil member extends longitudinally along at least a portion of the length of the wiper blade member. The airfoil member also has a cross-sectional profile that is symmetrical about a plane of symmetry extending through a center of the airfoil member and longitudinally through the airfoil member.

28. A method for extending a useful life of a symmetrical wiper blade assembly, the method comprising forming a symmetrical wiper blade assembly adapted to be used in a vehicle windshield wiper system for a predetermined time interval after which the wiper blade assembly is adapted to be rotated about 180°
- about a rotation axis that is substantially perpendicular to a length of the wiper blade assembly;
wherein the wiper blade assembly includes;
a wiper blade member which substantially defines the length of the wiper blade assembly; and
an airfoil member operatively connected to the wiper blade member, the airfoil member extending longitudinally along at least a portion of the wiper blade member length, the airfoil member having a cross-sectional profile that is symmetrical about a plane of symmetry extending through a center of the airfoil member and longitudinally through the airfoil member.
- about a rotation axis that is substantially perpendicular to a length of the wiper blade assembly;
