Description

{CAR SEAT WITH ADJUSTABLE WIDTH AND LENGTH}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car seat, and more particularly, to a car seat capable of adjusting the width and length of the body so that the width of the body and the length of the head can be adjusted.

Generally, when a vehicle such as a passenger car is carried, the safety belt is operated for the safety of the passenger. However, since most of the safety belts are installed on the basis of adults, it is not possible to wear seat belts in infants and children who are relatively small compared to adults. Therefore, a separate protective sheet for infants, And the vehicle is operated while the infant is seated on the seat mounted on the seat.

Background Art [0002] A conventional child car seat is composed of a base portion which is seated on a seat of a vehicle and a seat portion which is provided on the upper side of the base portion so as to allow the infant to sit thereon. The base portion serves to stably support the seat portion It is possible to adjust the angle of inclination of the seat portion or to change the installation direction of the seat portion forward and backward.

The seat portion serves to allow the infant to safely ride on the vehicle. To this end, the seat belt may be installed in a form that the seat belt passes through one side of the seat portion so as to surround the infant, or a separate seat belt So that the child can be wrapped.

In a conventional child car seat as described above, a consumer purchases and uses a child car seat having a size suitable for an infant's age at the beginning of purchase of the child car seat. When the infant's body grows as the infant grows, A new child car seat must be purchased and used so that a child car seat must be purchased every time the infant grows, which increases the economic burden.

In addition, even if a child of the same age is born, the size of the body varies depending on the degree of development. The conventional child car seat is manufactured according to the average body size according to age. Therefore, There is a problem that it is inconvenient to use because the size can not be controlled at all.

As the width of the car seat is widened, there is no product in which the adjustment of the height of the belt causes interlocking, and the width of the car seat is widened along with the growth of the infant.
