Although the birth rate is declining, the family structure in a typical household often has brothers and sisters two to three years old different from each other. Therefore, if the obligation to wear child seats is legislated, it will be necessary to purchase and equip multiple large child seats as described above, but purchasing such multiple child seats will increase the cost, There is a problem that the weight is increased and the fuel efficiency of the vehicle is deteriorated by installing a plurality of the devices.

In a home with many infants, if only one infant can sit in a seating space for one adult, the number of passengers (formerly, three children and two adults were counted) is limited. However, it is necessary to switch to a large passenger car, which is inefficient in reducing exhaust gas and fuel consumption. Further, in recent years, it has become common to equip vehicles with an airbag system. However, if a child seat is attached to a passenger seat with an airbag system, there is a problem that an infant may be injured by an impact of the airbag.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problem relating to a child seat, in which two infants can be seated in a space for one adult, and the child seat can be protected from the impact of an airbag. The purpose is to provide.
