Abstract
Abstract A window washer assembly which also provides a seal for a tailgate window of a station wagon. An inflatable resilient tube mounted on the tailgate carries a pair of blades engageable with the window. A washer fluid is pumped into the tube and ejected through holes between the blades. One of the blades may extend into engagement with the window in the deflated condition of the tube for sealing the space between the tailgate and window and at least one of the blades may be brought into wiping engagement with the window upon inflation of the tube during the washing operation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
114 words
A window washer and seal assembly comprising a tubular body of flexible, resilient material, a pair of blades extending along one face of said tubular body in spaced-apart relation providing a channel between said blades, mounting means on said tubular body for positioning said body in fixed relation to an associated window, means for communicating a fluid medium into said tubular body for distending said body and thereby biasing at least one of said blades into wiping engagement with said associated window and means for directing the fluid medium into said channel for wetting said associated window and said blades whereby said associated window may be washed and wiped when moved past said blades.
