[0002]

2. Description of the Related Art Conventionally, a so-called child seat has been used because it is impossible to wear an adult seat belt when an infant is put on a car. Since the child seat is installed in the passenger seat or the rear seat of the car, it becomes an obstacle when an adult rides, and it has to be attached or removed each time. Therefore, although the need for a child seat was recognized, the wearing rate was low.

Therefore, a model in which a child seat is incorporated in advance in a passenger seat or the like has been newly developed. 14 to 16 show an improved passenger seat of a passenger seat 102 including a seat cushion 100 and a seat back 101, which is a child seat. A part of the seat back 101 is tilted forward, This is a cushion 103 for an infant to sit on. The headrest 104 is bent downward to make the height of the cushion 103 constant, and
A fixing belt 105 built in the inside of the seat is attached to a buckle 106 attached to the seat cushion 100 to fix the cushion 103. And the cushion 103
A protective belt 107 built in the inside of the child is attached to the infant to fix the infant. Further, when an adult rides, the cushion 103 can be raised and used as a normal seat back 101.

[0004]

However, when the infant becomes a little larger, the reach of the door lock knob or the inside handle etc. can be reached by reaching for the infant.
Parental attention is required. Also, as the infant grows larger, the child seat becomes smaller and the usage period is limited.

The present invention solves the above problems and solves the problems of infants, school children,
An object of the present invention is to provide a car seat with a seat for a child, which can be used by an adult and in which an adult and a school child can also use a headrest.

[0006]

In order to solve the above-mentioned problems, the present invention solves the above-mentioned problems by providing a cushion for an infant on the front surface of a seat back that pivots around a lower end and falls forward, and a school child having a wider width than the cushion for the infant. A car seat with built-in cushions for side by side, which is formed by moving the seating center position when an adult sits from the seat center position to the cushion side for school children, and the headrest provided on the seat back for school children It was installed near the cushion for school children so that it doubles as a headrest.

[0007]

[Operation] When driving with the infant sitting on the passenger seat, the cushion for the infant should be folded down, the infant should sit down, and the protective belt should be attached to the infant. In this way, since the infant can be seated near the side of the guardian who is driving, the knob of the door lock or the inside handle becomes far away from the infant, and there is no risk of operating these things by mistake.
Next, in order to carry a school child larger than an infant, the school child cushion is laid down, the school child is seated on it, and the seat belt attached to the vehicle body is attached. In addition, both the infant and the schoolchild can be seated by folding down the infant cushion and the schoolchild cushion. When infants and school children grow up, the cushion for infants and the cushion for school children can be stored in the seat back and used as a normal seat. Also, since the seating center position when an adult sits is formed by moving from the seat center position to the cushion side for school children, the headrest is provided closer to the schoolchildren corresponding to the seating center position. And school children can also be combined.
