Windshield wiper assembly
摘要:
This invention relates to windshield wiper assemblies which include a wiping element and a pressure-distributing superstructure operatively connected together so as to transmit and distribute the pressure received by the pressure-distributing superstructure from the wiper arm to spaced locations along the length of the wiping element. The pressure-distributing superstructure comprises at least one lower member having an inverted V-shaped cross section and an upper member also having an inverted V-shaped cross section. The upper member is pivotally connected to the lower member by a pair of inturned tabs seated in a pair of notches in the lower member and has round embossments adjacent the inboard ends of the inturned tabs on each side of the underside thereof, which embossments engage the upper surface of the lower member when the lower member rocks with respect to the upper member.
