For the child in this use situation, since the headrest 30 does not need to be raised toward the first height section H1, the stopper 222 is located at the stop position, and accordingly, the second interference piece 211 is located at the first position and locked by being interfered by the first interference piece 132 located at the fourth position, the base 10 can be normally used without binding the safety belt 50;
the seat body is mounted forward in advance, with the headrest 30 located in the first height interval H1. Because the headrest 30 is at the first height interval H1, the stop block 222 is abutted against the release position, and the linkage 223 is pulled to lock the second interference piece 211 at the second position, so that the second interference piece 211 and the first interference piece 132 are pushed against each other, and the steam seat body cannot be mounted on the base 10 in the forward direction. The seat belt 50 is now strapped to the base 10 and the seat belt 50 unlocks the first interference member 132 in the fourth position so that it can switch to the third position retracted within the base 10. The second interference piece 211 and the first interference piece 132 are not pushed against each other any more, and the automobile seat body can be smoothly and forwardly mounted on the base 10;
the steam seat body is installed forward, and the headrest 30 is lifted to the first height interval H1 in advance. Referring to ii, to raise the headrest 30 to the first height interval H1, the locking of the stopper 222 at the stop position must be released. The seat belt 50 is now strapped to the base 10 and the seat belt 50 is unlocked from the first interference member 132 locked in the fourth position so that it can be switched to the third position retracted within the base 10. The second interference element 211 is no longer held by the first interference element 132, and the second elastic reset element 213 switches from the first position to the second position. Accordingly, the stop block 222 may be switched to the release position, no longer blocking the headrest 30 from rising to the first height interval H1.
