The belts on both sides were connected in such a way.

Therefore, since the force transmitted to the belt is a means for supporting the elasticity of the hook, it is easily separated when a strong force is applied, and thus there is a problem that it cannot be used as a safety belt for a vehicle or a safety belt for a car seat.

In addition, the conventional buckle could not visually check whether the fastener is inserted into the buckle case or slightly inserted.

Therefore, when the buckle is applied to a child car seat, it is inconvenient and inconvenient because it was possible to check whether or not the fastener was fitted into the buckle case by hand.
