A child safety seat includes a seat back and a head rest disposed on the seat back. When a child sits on the child safety seat, his back is against the seat back, and his head is against the head rest. The child safety seat also includes two sliding slot structures, formed on the seat back, and two sliding rods. The two sliding rod are connected to two opposite sides of the head rest corresponding to the two sliding slot structures and slidably disposed in the corresponding sliding slot structures. When the sliding rod is at a first restraining position of the sliding slot structure and the child safety seat shakes because of an impact, the head rest moves relative to the seat back, so that the sliding rod slides to a second restraining position sliding slot structure, which reduces possible harm to the head of the child. |

1. A child safety seat, having a seating orientation, the child safety seat comprising:
a seat back comprising:
a head portion;a torso portion;an insertion slot formed on the torso portion; andtwo side protection portions pivotally connected to the head portion oppositely; a head rest disposed on the seat back and located between the side protection portions, when a child is seated on the child safety seat, a back of the child being against the seat back, a head of the child being against the head rest and facing toward the seating orientation, the head rest having an edge portion movably inserted into the insertion slot; two sliding slot structures formed through the two side protection portions respectively, the sliding slot structure has a first restraining position and a second restraining position; and two sliding rods connected to two opposite sides of the head rest corresponding to the two sliding slot structures and slidably disposed in the corresponding sliding slot structures, each sliding rod having a retaining portion, passing through the corresponding sliding slot structure, and being capable of being located at the first restraining position or the second restraining position, wherein when the sliding rod is located at the first restraining position and the child safety seat shakes because of an impact, the head rest rotates relative to the seat back toward the seating orientation, so that the sliding rod slides from the first restraining position to the second restraining position, and the retaining portion is located at an outer side of the corresponding side protection portion opposite to the head rest, so that when the sliding rod slides from the first restraining position to the second restraining position, the retaining portion pushes the corresponding side protection portion so that the two side protection portions rotate relative to the head portion. |
