Abstract: A vehicle window regulating and sealing assembly for raising and lowering a window. The window is supported at the sides within vertical guide channels by pivotal sliding upper and lower guide members attached to the window. The guide channels include an outwardly extending curved ramp section within which the lower guide members track to cause the window to pivot about the upper guide members as it nears the raised position thereby causing the window to firmly bear against relatively non-yielding sealing members to establish a perfectly flush positioning of the window relative to the vehicle exterior.
