Patent ID: 11865953

Abstract:
The present disclosure discloses a child safety seat and a side impact protection mechanism thereof, the side impact protection mechanism is provided at a backrest of the child safety seat and includes a side impact protection block and a self-locking structure. The side impact protection block is movably fitted to the backrest and has 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. The self-locking structure automatically moves 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, the self-locking structure is fitted to the side impact protection block or the backrest, and 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, so that the side impact protection block cannot be inwardly folded into the backrest after the first use, thereby effectively preventing the side impact protection block from being accidentally folded during the side impact to provide a side impact protection effect.
