Abstract

A vehicle child seat is provided for directly or indirectly fastening to a vehicle seat and/or a vehicle structure. The vehicle child seat includes a backrest, a seat surface, an integrated belt system for fastening a child in the vehicle child seat and a belt tensioning device (31). The belt tensioning device (31) includes a trigger sensor, an energy storage device and a tensioning mechanism which, when exceeding a defined force acting on the vehicle child seat, in particular a crash force, abruptly tensions the belt system. All components of the belt tensioning device (31) required for the belt tensioning function being fastened to or in the vehicle child seat and being able to be removed therewith from the vehicle. A belt force limiting function is incorporated in the belt tensioning device (31). After triggering the belt tensioning device (31) when exceeding a limit force Fgrenz on the belt portion (11, 12, 13, 15) at least one belt deflector (137, 171) is displaced sufficiently far in the direction of a normal position, until the limit force Fgrenz has fallen below or the belt deflector (137, 171) has completely reached its normal position.
