Method for manufacturing a sliding glazing unit, and sliding glazing unit

A method for manufacturing a vehicle glazed unit, including a glass pane having an external face, an internal face and a peripheral edge, as well as an attachment system configured to allow mobility of said glass pane in vertical translation with respect to a door of a vehicle, said attachment system being located in at least one attachment zone and including a window holder having a U-shaped part, wherein said attachment system is attached to said glass pane by implementing at least the following acts:

• positioning said glass pane on a reference housing, then,
• applying an adhesive and positioning said window holder opposite a rim of said glass pane such that said adhesive is positioned in said U-shaped part, between at least said glass pane and said window holder,
• said window holder having at least one lateral extension, distinct from said U-shaped part and located opposite said glass pane, wherein the at least one lateral extension provides a pair of clasping parts on opposing face surfaces of the glass pane on at least one lateral side of the U-shaped part, and applying a quick-hardening plastic material:
• on the at least one lateral extension, including said clasping parts, or
• under the at least one lateral extension, including said clasping parts,
• or both;
• wherein the quick-hardening plastic material hardens to mechanically secure the glass pane between the clasping parts provided by the at least one lateral extension and fix the U-shaped part to the glass pane independently of a state of the adhesive.
