An external frame backpack (10) includes a frame (14), a hipbelt (32), two flexible stays (50, 52), a back panel (38), and a lower panel (40). The frame is external and substantially rigid. It includes upper, middle, and lower frame members (22, 24, 26) secured between frame side rails (18, 20). The hipbelt is attached to the frame adjacent the lower frame member. The flexible stays are elongate with upper and lower ends. The upper ends are attached to the upper frame member. The lower ends are attached to the sides of the hipbelt. The stays are flexible to allow movement of the hipbelt as the stays bend while transmitting at least a portion of the weight held on the frame to the lower end of the stays. The back panel is vertically and horizontally tensioned and secured to the frame. The lower panel is secured between the side rails of the frame. The lower panel includes a support sheet (66) to maintain the shape thereof when tensioned between the side rails.

Sac à dos à armature externe (10) comprenant une armature (14), une ceinture ventrale (32), deux baleines souples (5O, 52), un panneau arrière (38) et un panneau inférieur (40). L'armature est externe et sensiblement rigide. Elle comporte des éléments d'armature inférieurs, moyens et supérieurs (22, 24, 26) fixés entre des barres latérales de l'armature (18, 20). La ceinture ventrale est fixée à l'armature sur son élément inférieur. Les baleines souples se prolongent par des extrémités inférieures et supérieures. Les extrémités supérieures sont fixées à l'élément supérieur de l'armature. Les extrémités inférieures sont fixées aux côtés de la ceinture ventrale. Les baleines sont suffisamment souples pour permettre un mouvement de la ceinture ventrale lorsque lesdites baleines ploient tout en transmettant au moins une partie du poids porté sur l'armature aux extrémités inférieures des baleines. Le panneau arrière est tendu verticalement et horizontalement et est solidement fixé à l'armature. Le panneau inférieur est fixé entre les barres de côté de l'armature. Le panneau inférieur comprend une feuille de support (66) pour en maintenir la forme générale lorsqu'il subit une tension entre les barres de côtés.
