Beam blade wiper assembly having improved coupler

Abstract

A beam blade windshield wiper assembly having an elongated backbone defining a longitudinal beam length which extends between first and second longitudinal ends so as to define a longitudinal axis with an intermediate portion therebetween. The backbone has an upper surface and an opposed mounting surface with first and second sides extending between the upper surface and the mounting surface. A wiper element is mounted to the mounting surface of the backbone and extends for a substantial portion of its longitudinal beam length. The assembly further includes a coupler which is adapted to interconnect the backbone to a wiper arm. The coupler includes a spring clip mounted to the backbone and a coupler housing adapted to be mounted to the wiper arm. The spring clip includes a base supported on the upper surface of the backbone, a spring seat disposed spaced from the upper surface of the backbone and a spring biased tongue extending in the direction of the longitudinal beam length and disposed spaced from the upper surface of the backbone. The coupler housing defines a cavity and has a pivot pin extending across the cavity and transverse to the longitudinal beam length. The pivot pin is rotatably received and supported between the spring seat and the tongue with the tongue biasing the pin into engagement with the spring seat.
