A vehicle attachable child booster type car seat is provided with a lap belt for in situ restraining the car seat at a vehicle seat by using a vehicle safety seat belt having a first vehicle seat belt buckle and a first vehicle seat belt prong. In one embodiment of the present invention, a booster seat is configured to have a second vehicle seat belt buckle and a second vehicle seat belt prong to mate with the first vehicle seat belt prong and the first vehicle seat belt buckle, respectively, when positioned on the vehicle seat of a motor vehicle. Therefore, instead of the booster seat being merely an unattached cushion boosting a child occupant's position, may rather be anchored at the vehicle seat while the vehicle safety seat belt's functionality still retained along with an additional restraining capability of the lap belt that can secure a torso portion of the child occupant seated in the booster seat. Such anchoring of a body of the booster seat to a vehicle seat belt system near a seating base of the vehicle seat may avoid dislodging of a seat pan of the booster seat from the top of the vehicle seat in response to an impact force or sudden breaking of the motor vehicle.
