Title
(EN) DROP-IN SEAT UNIT
(FR) SIEGE RABATTABLE
Abstract
(EN)
The present invention provides for a drop-in seat unit (10) as well as a method of manufacturing the drop-in seat unit that does not require the worker to affix one end of the spring (40) to a frame rail (11) and stretch the spring from one of the frame rails to the other frame rail (12). The ends of the spring are affixed to the frame rails while the springs are in an unstretched state. Once the plurality of springs is attached to the two frame rails, the rails are mechanically pulled away from each other, thus created a larger open area between the frame rails and thus extending the springs. Once the rails are properly positioned in this extended state, support members (50) are positioned between the two frame rails and one end of each support member is affixed to each frame rail, traversing the space or gap between the two frame rails. The support members fix the distance between the two frame rails. Once the springs are attached to the two frame rails and the support members are affixed to the two frame rails, the completed drop-in seat unit or seat box assembly is undamped and released from the manufacturing apparatus and is ready for shipment or use in further construction of the sofa or chair.
(FR)
La présente invention concerne une unité de siège rabattable ainsi qu'un procédé de fabrication de ce siège qui ne demande pas à l'ouvrier de fixer une extrémité du ressort à un rail ni d'étirer le ressort depuis un des rails jusqu'à l'autre. Les extrémités du ressort sont fixées aux rails pendant que les ressorts sont dans un état non étiré. Une fois la pluralité des ressorts jointe aux deux rails de cadre, les rails sont mécaniquement écartés l'un de l'autre, ce qui crée une large ouverture entre les rails et tend ainsi les ressorts. Une fois les rails correctement étirés, les membres de support sont placés entre les deux rails du cadre et une extrémité de chaque membre de support est fixée à chaque rail de cadre, en traversant l'espace ou l'écart entre les deux rails. Les membres de support fixent la distance entre les deux rails du cadre. Une fois les ressorts et les membres support fixés aux deux rails de cadre, le siège terminé ou l'ensemble du boîtier est désamorti et détaché de l'appareil de fabrication et prêt à être expédié ou utilisé pour la construction ultérieure du sofa ou de la chaise.
