Abstract: The invention concerns a child seat device, in particular for securing a child in a motor vehicle, on land, sea and in the air, comprising seat and back portions with outer shells (1, 2) and inner inflatable cushions (3, 4), and side portions (5, 6, 7, 8, 9, 9′, 10) extending out-/inwards, preferably at right angles, relative to the seat and back portions. Further, the seat and back portions (1, 2, 3, 4) are pivoted to each other, and the side portions (5, 6, 7, 8, 9, 9′, 10) are pivoted to the respective ones of the seat and back portions, so that whenever required, the child seat can be folded up completely for storing when the cushions (3, 4, 7, 8, 10) are deflated.
