Luggage shell, luggage comprising such a shell, and method for manufacturing a luggage shell

1. A luggage shell comprising:

a structure having a general shell shape defining an internal volume and formed of a material comprising plastic or a composite material, an outer surface of the structure including a plurality of flat regions and a plurality of curved regions, each curved region comprising a cylindrical ridge having an angular extent of substantially 90°, and

a single covering sheet fixed on the outer surface of the structure, said covering sheet being of metal and having a thickness of between 25 μm and 1 mm, said covering sheet including a central region, a panel extending away from the central region, and a wing extending from an end of the panel remote from the central region, wherein a distal end of the wing is folded onto itself to form a folded portion,

wherein the covering sheet is formed by folding a flat sheet having an outline adapted so that, after folding, the covering sheet has a shape substantially identical to the outer surface of the structure,

wherein the outline is adapted so that, after folding, the covering sheet has a shape which cover seach flat and curved region of the outer surface of the structure, and

wherein the covering sheet is fixed to the outer surface of the structure.

2. The luggage shell according to claim 1 , wherein the covering sheet has a thickness of between 25 μm and 0.6 mm.

3. The luggage shell according to claim 1 , wherein the covering sheet is made of a material chosen from a list of metals comprising titanium, stainless steel, and aluminum.

4. The luggage shell according to claim 1 , wherein the material of the structure comprises a plastic of the thermoplastic or thermosetting type.

5. The luggage shell according to claim 1 , wherein the material of the structure comprises a filler incorporated into the plastic, said filler being in the form of fibers.

6. The luggage shell according to claim 5 , wherein the fibers are plastic fibers or glass fibers or carbon fibers.

7. The luggage shell according to claim 1 , wherein the outline is a cross shape.

8. A luggage shell according to claim 7 , wherein the flat sheet comprises at least:

a substantially rectangular main portion intended to cover an external main face of the structure, located opposite to an opening of the structure,

a first side portion extending from the main portion and intended to cover a first side face of the structure;

a second side portion extending from the main portion and intended to cover a second side face of the structure; and

at least four wings, each wing extending laterally from an end remote from the main portion, wherein the folded portion is fixed to the second side portion when said flat sheet is folded to form the covering sheet.

9. The luggage shell according to claim 7 , wherein the covering sheet is formed by folding prior to being fixed to the structure.

10. The luggage item comprising a first luggage shell according to claim 1 .

11. The luggage item according to claim 10 comprising:

a second luggage shell according to one of claims 1 - 6 , 8 - 9 ,

a hinge device connecting the first luggage shell and the second luggage shell, the second luggage shell being movable relative to the first luggage shell between a closed position and an open position by means of the hinge device,

a zipper fastener comprising a first strip connected to the first luggage shell, a second strip connected to the second luggage shell, and a slide that is movable along said first and second strips between:

a fastening position in which the first and second strips are held adjacent to each other, the hinge device then being in the closed position, and

a releasing position in which the first and second strips are released from one another.

12. The luggage according to claim 2 , wherein the covering sheet has a thickness of between 25 μm and 0.3 mm.
