Description

Infant car seat {Baby car seat and method of control baby car seat}

The present invention relates to a child car seat, and more particularly, it helps the infant to maintain a correct posture in the car seat, effectively protects the infant from accidents, the user can detect the infant's discomfort in advance, and can be easily stored .

BACKGROUND ART In general, when riding in various vehicles including a passenger car, the vehicle is operated with a seat belt fastened for the safety of occupants. However, since most seat belts are installed for adults, it is impossible for infants or children who are relatively small compared to adults to wear a seat belt. The vehicle is operated while the infant is seated in the car seat. The conventional car seat has a structure in which a cushion material cover paper is surrounded on a chair-shaped body without legs usually made of a plastic material, and a pair of fastening belts connecting the bottom surface from the front upper part of the backrest are mounted. The movement of the body of the seated infant is suppressed by the fastening belt that is fastened between the crotch through both shoulders.

However, in this conventional child car seat, the seat belt prevents the infant from being thrown out of the car seat and absorbs the shock with the seat cushion at the same time when the vehicle is in an accident. It is not easy to completely protect the infant from the impact of There is a problem that it cannot detect.
