Abstract: A child safety harness for securing children to a seat of a vehicle is disclosed herein. The child safety harness comprises a pair of shoulder straps, a torso strap mounted to the pair of shoulder straps, and a back strap mounted to the pair of shoulder straps and the torso strap. As a result, the child safety harness can fit all children and relieves the discomfort caused by other harnesses. The child safety harness comprises a connector provided at the back strap. The connector allows the child safety harness to be easily removable from the seat of the car. The connector is used to mount the child safety harness to the seat belt via the back strap to secure the child to the seat of the vehicle. In one embodiment, the child safety harness is adapted to strap multiple children through the use of one lap belt and shoulder belt.
