In a tilting window having a sash journalled on a horizontal axis at the lowermost end of a suspension arm which through two further arms or links of different lengths are movably connected to the main frame of the window, the sash is moreover connected with one of said further arms through an additional link coordinating the tilting movement of the sash with the angular movement of said one arm. The suspension arm may at the same time serve as a cover band for the upper portions of the side members of the sash and the main frame.
