Patent ID: 8099824

Claim:
A squeezing device for a wiping cover of a flat-body wiper having a wiper plate moveable to a vertical position in which the wiping cover hangs downward partially detached from the wiper plate, the wiper plate including a downward facing pressure surface in the vertical position, the squeezing device comprising: a funnel, having a first tapered rectangular cross-section and a squeezing shaft having a second tapered rectangular cross-section, wherein the second cross-section is narrower than the first cross-section and wherein the second cross-section has a first set of two diametrically opposed inner walls configured to receive and simultaneously support the wiping cover and a first guide element disposed on one of the first set of walls configured to stabilize the wiping plate against tipping a first plane toward the two diametrically opposed inner walls, the shaft including a counterpressure surface in a lower region of the squeezing shaft so that a squeezing pressure of the pressure surface against the counterpressure surface squeezes out the wiping cover, wherein the second cross-section further comprises a second guide element disposed on one of the first set of walls configured to interact with a corresponding counter-guide element on the wiper plate to stabilize the wiper plate against tipping relative to a second plane perpendicular to the first plane.
