Abstract: A child safety seat having a seat, a backrest, and a belt device for buckling a child therein. The belt device includes a shoulder belt routed through an opening in the backrest. The opening includes a longitudinal slot extending in a longitudinal direction of the backrest in a reclining element and a belt slot in a belt guide piece. The guide piece is movable along the reclining element to adapt the position of the belt slot to the child's body. The guide piece detachably connects to the reclining element via a locking device having a locking element pretensioned by a reset force. An actuating element on the reclining element applies tensile force to the tensioning element, counter to the reset force. This moves the locking element into a release setting, thus releasing the locking device and displacing the guide piece along the longitudinal direction of the backrest.

Abstract: A child seat having a seat surface, a backrest, and a headrest. The headrest has first and second side pieces adjustable in their spacing relative to one another in a substantially horizontal direction. The side pieces are positionable in at least two different positions with respect to one another and to the backrest by means of a spacing adjustment device. The spacing adjustment device includes a gear mechanism having a first gear element rotatable around a rotational axis and a second and third gear element, each movable in a translational manner. The second gear element connects to the first side piece and the third gear element connects to the second side piece. The first gear element couples to the second and third gear elements such that, by means of rotation of the first gear element, opposite and simultaneous translational motions of the second and third gear elements are effected.
