Universal wiper adapter and wiper blade assembly incorporating same
View Patent ↗The present invention relates to a universal wiper adapter for connecting a wiper blade assembly to a wiper arm including a pair of sidewalls having an aperture and a land extending between the sidewalls cooperating to define a channel. The present invention further includes a cantilevered beam, between the sidewalls, having a super-surface and a subsurface each cooperating with the sidewalls to define an elongate passage and an elongate track, respectively. The channel and the elongate passage cooperate to receive two sizes of hook-type wiper arms, while the channel and the elongate track cooperate to receive three sizes of hook-type wiper arms. The present invention also includes a substrate between the sidewalls cooperating with the land and the apertures to receive two sizes of pin-type wiper arms. The substrate further cooperates with the sidewalls and the land to define an elongate cavity to receive a bayonet-type wiper arm.
