Windshield wiper assembly
First Claim
1. A wiper assembly attachable to a wiper arm of a motor vehicle for wiping a window thereof, said assembly comprising:
- a blade element comprising;
an elongated elastomeric blade having an elongated wiping edge; and
an elongated blade retainer coextensive with and supporting said blade, said retainer having two ends and an elongated midportion; and
a unitary support body for supporting said blade element, said body having first and second end portions and a central portion extending between said end portions, said central portion including an interconnect region for interconnection with the wiper arm, said first and second end portions each having gripping means, said gripping means operative to grip said blade retainer adjacent said ends of said blade retainer, said support body being operative to exert lengthwise tension on said blade retainer;
said blade supported in said retainer such that said blade is free to move along the length of said retainer so that when tension is exerted by said body on said retainer, said tension is not transferred to said blade.
