Problems solved by technology

This kind of limiting structure generally has to bear the full weight of the seat, and its strength is not enough.

There are also seats that bear weight through the base, and the limit structure only plays a role in limit. However, with this structure, when there is an accident such as sudden braking, the seat will have a tendency to turn forward, and the force of the turn will be all It is borne by the limit structure, and the limit structure is not strong enough, which will bring safety hazards to the child seat, and the structure needs to be improved
