摘要： The invention relates to a child seat (1) which can be fastened to a vehicle seat of a motor vehicle by means of a three-point seat belt (14). It is also possible for the child seat also to be connected to the supporting structure of the vehicle via an ISOFIX fastening system (17). The three-point seat belt (14) is equipped with a tightening device. The child seat (1) has its own belt system for securing a child sitting on the child seat. According to the invention, it is proposed that the three-point seat belt (14) be coupled to the belt system of the child seat (1). This coupling makes it possible, during a preventative or crash-active tightening of the three-point seat belt (14), for the belt system of the child seat (1) also to be tightened without a separate tightening device being necessary.
