Claim 15:
16. A child safety seat comprising a seat part and a backrest fitted with the seat part, wherein the child safety seat further comprises the side impact protection mechanism; the side impact protection comprises:
a side impact protection block movably fitted to the backrest and having a folding position in which the side impact protection block is inwardly folded in the backrest and an unfolding position in which the side impact protection block is outwardly unfolded from the backrest; and
a self-locking structure fitted to the side impact protection block or the backrest;
wherein the self-locking structure is configured to move to a position that blocks the side impact protection block in the unfolding position from switching to the folding position when the side impact protection block is switched from the folding position to the unfolding position;
wherein the backrest and the side impact protection block shields the self-locking structure to block a release operation of the self-locking structure by an operator;
wherein the self-locking structure comprises a self-locking member fitted to the backrest or the side impact protection block and being telescopically slidable, and a self-locking reset member providing a reset force for a telescopically slidable movement of the self-locking member, the self-locking reset member has a constant tendency to drive the self-locking member to slide in a extending direction to a position that blocks the side impact protection block in the unfolding position from switching to the folding position;
wherein the self-locking reset member is an elastic member provided between the self-locking member and the side impact protection block or the backrest on which the self-locking member is located; and
wherein the backrest is provided with a metal sheet, the self-locking member inserts through the metal sheet, and the elastic member is provided between the self-locking member and the metal sheet.
