Abstract

A child safety seat includes a seat shell, a headrest, a guiding component, slidably coupled to the seat shell, for guiding a strap of an integral harness system, and an adjustment mechanism for adjusting the height of the headrest. The adjustment mechanism includes a coupling element which is configured to be placed in a first and a second configuration, and, when placed in the first configuration, the coupling element couples the headrest with the guiding component such as to allow for movement of the headrest together with the guiding component relative to the seat shell. When placed in the second configuration, the coupling element couples the seat shell with the guiding component to prevent the guiding component from movement relative to the seat shell and to allow for movement of the headrest relative to the seat shell.
