The detailed description of invention

Referring to Fig. 1 and 2, combination knapsack of the present invention and chair 10 have braces 12, allow the user carry on the back at back.The knapsack part 14 of this knapsack chair 10 is similar to common knapsack, but a chair back and seat part 16 are arranged.

Referring to Fig. 3, seat part 18 links to each other with chair back portion 20 along lower area 22.A pair of fastening belt 24 is attached to the above-mentioned part 26 of knapsack part 14, is used for making a part 16 to abut on the chair back part 20 with closure state.Restraint zone can utilize hook and loop type material 28, places the bottom of a part 18 materials 32 with Weir Crow (uelcro) additional mutually hook and loop material 30 as the termination.Other modes also can be used to optionally make a part 18 to remain closed the orientation, contiguous chair back part 20, for example clip, slide fastener, band or other devices.Return Fig. 1, the back-packing of knapsack 10 is back ofs the body that the bottom surface 32 of a portion 18 gets close to the user.

Seat part 18 preferably has a quilting material 34 and primer 32, and the centre accompanies gasket material 36 (the foam rubber section bar material that for example original position is light).The liner foam rubber material also preferably is clipped in the centre of chair back part 20 and seat and the dorsal part wing 38 and 44.Gasket material makes the shape of seat more even, and preventing has too much " hillock " when the user from sitting.The top preferably is coated with nylon with

Referring to Figure 10, show the view that the part of Fig. 1-9 combination knapsack and

chair

10 and 80 is removed,

knapsack part

14 and 82 can be furnished with and be isolated and the lower part 102 of waterproof.The lower part 102 of this isolation can be used to adorn people and wishes to keep the bag and bottle that cools off, as six bag soft drinks.Lower part 102 preferably is lined with waterproof material 104, draw (Mylar  as vinyl, coating nylon, plum,) and so on, the also the most handy insulating materials 108 of wall around all lower parts 102 comes liner, for example with thin foam rubber, foamed polystyrene or other known isolated materials.Lower part 102 preferably easily enters from top portion 110, and this is feasible, just draws back as long as will link the slide fastener of the lower part 102 of

knapsack

14 or 82 and the periphery on top 114.

Accompanying drawing and above description are not in order to set forth about the structure detail of invention and only a kind of form of mode of operation.In fact, for one be conspicuous to this professional veteran, need not deviate from spirit of the present invention and scope, can make multiple modified form and mutation.Although used particular term, also just be intended to general description, rather than the purpose in order to limit, scope of invention is set forth in following claim.
