DETAILED DESCRIPTION

[0027] FIG. 1 shows a child seat assembly 1 according to the invention for a vehicle in section with a child K sitting on it. The child seat assembly 1 thereby comprises a seat cover 2 and an air conditioning modulenot shown herecomprising a fan. The fan of the air conditioning module can thereby be coupled to the seat cover 2 so as to guide air, and air can flow through the seat cover 2. The seat cover 2 comprises an air-guiding inner layer 3, an air-permeable outer layer 4, and an air-impermeable bottom layer 5. The inner layer 3 is thereby arranged between the outer layer 4 and the bottom layer 5 and is laterally closed by a hem 6 in an air-tight manner. Outlet openings 7, through which air can flow, are formed in the hem 6, so that the air flowing out of the seat cover 2 can flow through the outlet openings 7. The seat cover 2 is arranged on a child seat 8, so that a corresponding thermal comfort is offered to the child K in the child seat 8. The outer layer 4 is thereby not only permeable for the air, but also for the moisture, so that the moisture can reach into the inner layer 3 via the outer layer 4. The moisture absorbed by the inner layer 3 can thereby be discharged from the seat cover 2 through the outlet openings 7 with the air, which flows through, as is suggested by means of arrows.

[0028] The outlet openings 7 thereby remain open, regardless of the sitting position of the child K, so that an optimal ventilation of the seat cover 2 is attained at any point in time. Heat and/or moisture accumulations in the seat cover 2 can thus be avoided in an advantageous manner, and a sufficient thermal comfort can be offered to the child K.

[0029] FIG. 2 shows a side view of the child seat assembly 1 at the outlet opening 7. Here, the hem 6 encompasses the inner layer 3, the outer layer 4, and the bottom layer 5, and closes them laterally. The outlet opening 7 is formed here by an air-permeable area of the hem 6. FIG. 3 shows a view and FIG. 4 shows a sectional view of the child seat assembly 1 at the outlet opening 7, in which a circumferential sleeve 9 is arranged. The outlet opening 7 thereby penetrates the hem 6 and is dimensionally stabilized by means of the circumferential sleeve 9, which can be flown through. For this purpose, the circumferential sleeve 9 is formed to be dimensionally stable and advantageously prevents a blocking of the outlet opening 7 and a redistribution of the air flowing through in the seat cover 2 resulting therefrom. An area 10 of the hem 6 including the outlet opening 7 thereby encloses the circumferential sleeve 9 from the outside, and the outlet opening 7 can be flown through through the circumferential sleeve 9. The shape and the cross section of the outlet opening 7, which can be flown through, are consequently determined by the shape and the cross section of the circumferential sleeve 9, which can be flown through.

[0030] FIG. 5 shows a sectional view of the circumferential sleeve 9, which has an oval cross section, which can be flown through. Deviating from this, the circumferential sleeve 9 in FIG. 6 has a round cross section, which can be flown through. Sectional views of the circumferential sleeves 9 of varying designs are shown in FIG. 7 and in FIG. 8. Two adjacent sleeve openings 11, which are separated from one another by means of a separating wall 12, are arranged inside the circumferential sleeves 9 here. The separating wall 12 additionally stabilizes the respective circumferential sleeve 9. The cross section of the respective circumferential sleeve 9, which can be flown through, consists of the cross sections of the respective sleeve openings 11, which can be flown through. Regardless of the design of the circumferential sleeve 9, the cross section thereof, which can be flown through, can be adapted to the desired distribution of the air, which flows through, in the seat cover 2. The circumferential sleeves 9 shown in FIG. 7 and FIG. 8 each have two sleeve openings 11. The circumferential sleeve 9 can generally also have a differing number of sleeve openings 11. The sleeve openings 11 can further have a shape, which differs from the shapes of the sleeve openings 11 shown here.

[0031] FIG. 9 to FIG. 13 show views of the child seat assembly 1 comprising a differing distribution of the air, which flows through, in the seat cover 2. A view of the seat cover 2 comprising three outlet openings 7, which are formed spaced apart from one another in the hem 6, is shown in FIG. 9. Air thereby flows through the seat cover 2 from an air inlet 13 comprising a single inlet opening 14 to the respective outlet openings 7, as is suggested by means of arrows. Two blocking elements 15for example separating walls, seams, embossings or guide elementswhich divide the inner layer 3 into three flow ducts 16, are additionally arranged in the seat cover 2. The respective flow ducts 16 lead from the air inlet 13 or from the inlet opening 14, respectively, to the respective outlet openings 7, so that moisture can be discharged efficiently and evenly from the seat cover. The respective flow ducts 16 inside the seat cover 2 are thereby connected to one another at the hem 6 and at the air inlet 13 so as to guide air. Deviating therefrom, the seat cover 2 in FIG. 10 has the air inlet 13 comprising two inlet openings 14. The seat cover 2 further has a total of four outlet openings 7, three blocking elements 15, and four flow ducts 16. Here, the respective flow ducts 16 are connected to one another at the hem 6 and in pairs at the air inlet 13 so as to guide air. It goes without saying that the supports 2 shown here are only exemplary. Fewer than two or more than three blocking elements 15 can generally also be arranged in the seat cover 2, and the inner layer 3 can accordingly be divided into fewer than three or into more than four flow ducts 16. The air inlet 13 can also have a differing number of the inlet openings 14.

[0032] FIG. 11 now shows a view of the seat cover 2 comprising an uneven distribution of the air, which flows through, at the outlet openings 7. At the lateral outlet openings 7, approximately 25%, and at the outlet opening 7 located opposite the air inlet 13, approximately 50% of the air, which flows through the air inlet 13 to the outlet openings 7, escapes. In the seat cover 2, this is attained by means of a differing width of the respective flow ducts 16. By way of comparison, a view of the seat cover 2 comprising the even distribution of the air, which flows through, is shown in FIG. 12. The flow ducts 16 are designed in such a way here that approximately 33% of the air, which flows into the air inlet 13, escapes at each outlet opening 7. Only the distribution of the air, which flows to the outlet openings 7, is shown in FIG. 11 and FIG. 12. If the outer layer 4 and/or the bottom layer 5 are air-permeable, only a portion of the air, which flows into the seat cover 2 in total, flows out of the outlet openings 7. It goes without saying that the distribution of the air, which flows through the air inlet 13 to the outlet openings 7, shown here, is only exemplary. Other distributions of the air, which flows through the air inlet 13 to the outlet openings 7, can generally also be realized in the seat cover 2.

[0033] FIG. 13 now shows a view of the seat cover 2 comprising the flow ducts 16 of varying designs or comprising the blocking elements 15 of varying designs, respectively. Here, the flow ducts 16 are not connected to one another so as to guide air at the hem 6, so that the air is forced into the respective outlet openings 7. The blocking elements 15 further have a differing distance H1 and H2 to the air inlet 13 of the seat cover 2.

[0034] In summary, the child seat assembly 1 according to the invention can offer a high thermal comfort to a child K in the summer as well as in the winter. The heat and/or moisture accumulations in the seat cover 2 can in particular be prevented and an optimal distribution of the air, which flows through, can be attained in the seat cover 2.
