An annular outer frame mounts the assembly in a vehicle. A pair of pivots rotatably support an inner frame (which mounts a window) for rotation about an offset axis between open and closed positions. The pivots can support a frameless window. One of the pivots has a spring-like arm actuated by manually twisting a handle. The arm grips a pivot stud which locks the inner frame or window in a desired position or by proper setting, the gripping pressure exerted by the arm on the stud can provide for a clutch action.
