Abstract: The invention relates to a window 20 comprising a steady frame 22, a movable frame 24, and an actuator 26 for moving the movable frame 24. The steady frame mainly extends in a plane ?, comprises at least one plate 220 which mainly extends in a plane ? perpendicular to the plane ?, the plate 220 comprises a main track 222 and an auxiliary track 224. The movable frame extends predominantly in a plane ? perpendicular to the plane ? and comprises: at least one pivot 242 defining a rotation axis X, perpendicular to the plane ? and parallel to the planes ? and ?, the pivot 242 being conformed so as to be able to be slidingly held in the main track; at least one pin 244 which is rigidly mounted on the movable frame, which extends in a direction parallel to axis X, which is spaced from axis X, and which is conformed so as to be slidingly held in the auxiliary track.

Abstract: The present invention relates to an elongated structure 20 for a window frame 200 suitable for supporting a panel 19 for separating an inner environment from an outer environment. The elongated structure comprises a first crosspiece 21 defining a first abutment surface 211; a second crosspiece 22 defining a second abutment surface 222, parallel to the first abutment surface, and a truss structure 23 which connects the first crosspiece to the second crosspiece. The truss structure comprises rods 230 extending from connection zones 213 of the first crosspiece to connection zones 223 of the second crosspiece; in the elongated structure according to the invention, the rods are tapered.
