Abstract: The present invention relates to a child safety seat (1) comprising at least a head section (3), a back section (4) and a sitting section (5), where a base frame (7) is connected through pivot means (9) to the sitting section of the child safety seat, the pivot means (9) preventing the sitting section (5) from separating from the base frame (7), thereby providing a fixed connection between the sitting section (5) and the base frame (7) under normal utilization of the child safety seat (1), but allowing the head section (3), back section (4) and sitting section (5) to rotate sideways about a pivot axis in the event of a collision.
