Patent number: 6119302Abstract: A wiper squeegee is mounted in the holding claws of a support frame. The capability of the wiper squeegee to shift in the longitudinal direction is limited by a fixed first stop on a first end of the support frame and a second stop which can move between a holding position and a release position on a second end of the support frame. An end piece on which the second stop is mounted is fastened on the second end of the support frame so that the end piece can rotate around a geometric axis which runs at least approximately parallel to the longitudinal direction of the wiper squeegee. This end piece can be locked, at least in the holding position.Type: GrantFiled: June 16, 1998Date of Patent: September 19, 2000Assignee: ITT Manufacturing Enterprises, Inc.Inventors: Bruno Egner-Walter, Eckhardt Schmid, Wolfgang Scholl, Klaus Jaisle
