AMENDED CLAIMS
received by the International Bureau on 17 October 2007 (17.10.2007)

1. Fuselage structure, in particular of an aircraft or spacecraft comprising:
an inner shell arrangement (20) which has an upper inner shell (21) and a lower inner shell (22), the upper inner shell (21) being spaced apart at least in some sections from the lower inner shell (22) by a first gap (23) in order to form a window region;
a window band (41) which is arranged at least in the window region and has a pane device which comprises a grid structure (10) which absorbs fuselage forces;
wherein the fuselage structure comprises an outer shell arrangement (30) which has an upper outer shell (31)
associated with the upper inner shell (21) and a lower outer shell (32) associated with the lower inner shell (22), the upper outer shell (31) being spaced apart at least in some sections in the window region from the lower outer shell (32) by a second gap (24);
c h a r a c t e r i z e d i n
that the grid structure (10) extends beyond the window region, which is formed by the first and second gaps (23, 24), into the shell arrangements (20, 30) and can be fastened to the individual shells (21, 22; 31, 32) of the shell arrangements (20, 30) in order to form a fuselage structure which connects the individual shells (21, 22; 31,. 32) to one another and is optimized in terms of force flux.

2. Fuselage structure according to Claim 1, characterized in that the grid structure (10) has individual grid ribs (11) for forming grid meshes (12), the grid structure (10) being designed to absorb the forces occurring in the fuselage.

3. Fuselage structure according to claim 1 or 2,
characterized in that the grid structure (10) is designed as a lattice grid structure or the like and, in terms of shape configuration, is matched to the shape of the shell
arrangements (20, 30).

4. Fuselage structure according to any of the preceding claims, characterized in that the first gap (23) and the second gap (24) are formed at the same height and, at least in some sections, such that they run in the longitudinal
direction of the fuselage structure, in order to form an optimized window region.

5. Fuselage structure according to any of the preceding claims, characterized in that the first gap (23) and the second gap (24) have the same gap widths and/or gap lengths.

6. Fuselage structure according to any of the preceding claims, characterized in that the pane device has at least two individual panes (42, 43) which each end flush with the associated inner and/or outer shells (21, 22; 31, 32), can be fastened to the inner and/or outer shells (21, 22; 31, 32) and enclose the grid structure (10) between them.

7. Fuselage structure according to any of the preceding claims, characterized in that a suitable core material is provided between the inner shells (21, 22) and the outer shells (31, 32), at least with the exception of the window region.

8. Aircraft or spacecraft with a fuselage structure which is designed according to at least one of Claims 1 to 7.
