Patent attributes
A windshield wiper includes a blade assembly, which has a primary frame member having opposite ends to which secondary frame members are respectively connected. The primary frame member forms a central opening delimited by two side walls. A retain carrying a positioning bar is received in the opening. An arm coupler is received in the opening and has an inner wall section and an outer wall section through which mounting holes are defined. Fixing pawls extend downward from the inner wall section to engage the retainer for fixing the arm coupler. The mounting holes serve to couple to a wiper arm of a vehicle for driving reciprocal motion of the windshield wiper. The arm coupler can be mounted to the primary frame member in different directions so that the windshield wiper is suitable for both left hand drive vehicles and right hand drive vehicles.
