Abstract

The present disclosure relates to a child safety seat. The child safety seat includes: a seat base defining a receiving groove on a front edge thereof; a buckle connected to the seat base through a crotch belt, and a shape of the buckle being matched with the receiving groove; and a seat cushion covering on the seat base and defining a slot to allow the buckle to pass through. When the buckle is no longer used, the buckle can be received in the receiving groove without removing the buckle, which does not affect the normal use of the seat base, and improves the convenience of using the child safety seat for users.
