Abstract

There is provided a device which may be used as a rucksack frame in a first functional position and as a chair with a backrest in a second functional position. The device comprises a first and a second frame member with mutually parallel side parts of which the side parts of the first frame member have end portions which are hingedly connected to respective side parts of the second frame member at a distance from the ends of the latter frame member so that the side parts of the frame members may be disposed parallel with and at right angles to each other, respectively. At the end opposite to the articulated end portions the first frame member has a support portion projecting from the side parts a distance essentially corresponding to the distance between the hinge connections and the outer end of an end support portion of the second frame member, the support portions cooperating as chair supports in said second functional position of the device.
