10. The frame structure according to claim 9, wherein the shell element has a through-hole for the fastening arrangement only on the side adjacent to the first protrusion.

11. The frame structure according to claim 2, wherein the first and second protrusions of the profiled frame element are arranged mirror-symmetrically to one another.

12. The frame structure according to claim 1, wherein the child seating arrangement comprises at least one of a perambulator, a child seat, and an infant carrier.

13. A perambulator that comprises the frame structure according to claim 1.

14. A child seat that comprises the frame structure according to claim 1.

15. An infant carrier that comprises the frame structure according to claim 1.

16. A shell element of the frame structure of a perambulator, child seat or infant carrier, comprising: a sleeve; an inwardly projecting first protrusion; on one side surface only of the sleeve includes at least one through-hole configured as a fastening arrangement, and that extends through the first protrusion; and a second inwardly projecting protrusion; wherein a blind hole is located in the second protrusion, and wherein the blind hole opens into an inner space of the sleeve; and wherein the profiled frame element is a one-piece body.

17. The shell element according to claim 16, wherein the two protrusions are provided on opposite inside surfaces of the shell element.

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Further advantages and features of the present invention will now be described with reference to the described embodiments, wherein features of individual embodiments can be combined with each other to form new embodiments. In the drawings:

(2) FIG. 1 is a perspective view of a first preferred embodiment of the frame structure according to the invention;

(3) FIG. 2 is a partially cut view of the embodiment as per FIG. 1;

(4) FIG. 3 is a partially cut perspective view of an embodiment of a profiled frame element; and

(5) FIG. 4 is a partially cut cross-sectional view of the embodiment as per FIG. 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) FIGS. 1 to 4 show a preferred embodiment of a frame structure according to the invention or a profiled frame element according to the invention.

(7) As revealed, in particular in FIG. 1, the frame structure 1 has a profiled frame element 2, to which a shell element 4 is attached by means of fastening means or arrangement 6.

(8) The profiled frame element 2 extends along profile direction X and is designed so as to result in a profile body, the cross-section of which does essentially not change in profile direction X, but remains constant or the same.

(9) The profiled frame element 2 is configured as a closed cross-section, thereby limiting an interior or inner space or hollow space 8. A first protrusion 10 and a second protrusion 12 are formed on the inside or inner surface or wall of the profiled frame element 2. The protrusions 10, 12 extend in profile direction advantageously over the entire profile length. Advantageously the profiled frame element 2 is configured mirror-symmetrically to a symmetry plane Y, wherein conveniently the projections 10, 12 are arranged mirror-symmetrically to one another.

(10) Corresponding to the protrusions 10, 12 the profiled frame element 2, on its outer wall or outer surface, comprises a first groove 14 and a second groove 16 respectively, as shown in particular in FIGS. 2 and 3. Advantageously the first groove 14 and the second groove 16 are also arranged mirror-symmetrically to each other relative to the symmetry plane Y (see FIG. 4).

(11) On a first side 18 or side surface, the profiled frame element has two through-bores or through-holes 20, which extend from the outside into the hollow space 8. The through-holes 20 are aligned with or lie on the first groove 14. In an alternative or additionally preferred embodiment the through-holes 20 are aligned or lie such that they protrude through the first protrusion.

(12) Coaxially to the through-holes 20 blind holes 22 are formed in the second protrusion 12 (shown as a broken line in FIG. 4), which extend from the inside or hollow space 8 into the second protrusion 12, without penetrating the wall of the profiled frame element 2 through to the outside.

(13) The shell element 4 comprises a cross-sectional configuration which is designed such that its inside essentially corresponds to the outside of the profiled frame element 2 or is congruent with it (see FIG. 4). The shell element 4, on its inwardly facing side towards the first groove 14 and the second groove 16 of the profiled frame element 2, comprises congruent protrusions 24. Following positioning of the shell element 4 on the profiled frame element 2 these protrusions lock into the first or the second groove 14, 16, thus enabling the shell element 4 to be pre-fixed on the profiled frame element 2. In order to fully fix the shell element 4 to the profiled frame element 2, the shell element 4 comprises through-holes 26, through which the fastening means 6 engage. This enables the shell element 4 to be attached to the profiled frame element 2.
