ABSTRACT:
The passenger side wiper of a tandem pattern system, in order to reach sufficient area of a sloped windshield, must have an effective wiping length that is longer that the space available in which to depress park the wiper along the lower edge of the windshield. In order to achieve this, the passenger side wiper is provided with a blade assembly that extends and retracts in a parallel swinging motion that does not depart unacceptably from the normal blade to arm orientation. The blade retracts automatically, activated by the already provided depressed park action.
