Abstract: A window element for a side door of a vehicle has at least one frame element including a guide and defining interconnected first and further window portals. A side pane is guidable by the frame element along the guide between a position closing the window portal and at least one position releasing the first window portal. The window element has a window web by which a frame part of the frame element is covered, at least in some regions. The frame part spatially separates the first and further window portals, and has a side pane held rigidly on the frame element. The further window portal is covered by the side pane that is held on the frame element, at least in some regions, with at least one plastics material, via which a screwed connection to the window web and/or to a door carcass of the side door is formable.
