  • Patent number: 11479152
    Abstract: A child safety seat (1) is held in a vehicle by a vehicle seat belt (70). The child safety seat (1) includes a seat shell comprising a base section (20) and a backrest section (10), and a tensioning system (50) that acts to alter the effective path of travel of the vehicle seat belt (70). The tensioning system (50) comprises a pair of belt carriages (56) for acting upon intermediate portions of the belt (70). The belt carriages (56) are adjustably moveable relative to the seat shell such that the effective path of travel of the vehicle seat belt (70) is able to be adjusted to increase tension in the seat belt (70). The child safety seat (1) can be correctly installed in the vehicle and can ensure that any remaining slack is removed from the vehicle seat belt (70), such that in the event of an accident, movement of the child safety seat (1) relative to the vehicle is reduced.
