Abstract
Abstract A child seat includes a seat body having a seat portion, a rear portion, and left and right side panels; airbags to be inflated at sides of a head of a child; and hollow cushions disposed along inner surfaces of the side panels. When an automobile equipped with the child seat collides, the airbags are inflated at the sides of the head of the child, so that an impact applied to the head is absorbed. Furthermore, the cushions absorb a large impact from sides in a side collision and the like. The cushions are preferably disposed below regions where the airbags are inflated. The cushions receive a part of the child other than the head to absorb the impact.
