This has the following disadvantages.

The belt easily bites into the child's buttocks and crotch, causing pain and discomfort.

[0005] Since the child is pushed forward in response to an impact such as a head-on collision, the belt further penetrates into the child's crotch. This is particularly severe when used by boys, and the impact of the bite may directly hit the penis or the Bimaru and cause injury.

When the auxiliary safety belt is pulled by the impact of the accident, the portion entangled with the seat belt is bent, and the child jumps forward by the amount of the bending, and the object in front of
For example, there is a risk of hitting a seat or a dashboard, which is dangerous.

[0007] When the belt is made of a soft material such as cloth, the belt is particularly slipped off the shoulder and easily comes off the shoulder of the child because of the softness, which is very dangerous in an accident.

The present invention has been made to solve the above-mentioned drawbacks.

[0009]

According to the present invention, at least a portion of the back of the auxiliary safety belt is formed of a portion made of a hard material, and the portion is formed to be longer than at least the width of the belt of the seat belt. .
