The safety belt has a connecting end extending outside the seat body, and the length of the safety belt extending out of the seat body is adjustable. The locking member is used to lock the length of the safety belt extending out of the seat body.

[0007] The connecting seat is movably arranged on the seat body. The safety belt has a bound state and an unbound state. When the safety belt changes from the bound state to the unbound state, the connecting seat moves from a first position to a second position, and the connecting seat is arranged in cooperation with the locking member at the second position to unlock the locking member.

[0008] Preferably, the safety belt has an adjusting end which passes through the locking member and is locked by the locking member. When the connecting seat moves from the first position to the second position, the locking member changes from a locked state to an unlocked state, and the safety belt changes from the bound state to the unbound state, so that the safety belt can be extended and retracted relative to the seat body to adjust the length of the connecting end extending out of the seat body, thereby adjusting the tightness of the safety belt. The locking member is a CFA, which is used to lock and unlock the adjusting end of the safety belt. When unlocked, the length of the connecting end of the safety belt extending out of the seat body is adjustable, thereby adjusting the tightness of the safety belt.

[0009] According to some preferred embodiments of the utility model, the safety belt is matched with the connecting seat in the bound state, and the connecting seat is located at the first position.

[0010] According to some preferred embodiments of the utility model, the restraint assembly further has a buckle arranged on the seat body, the connecting end is detachably fixed on the buckle, and the buckle is located at the front side of the connecting seat, so that when the connecting end is buckled to the buckle, the connecting seat is located at the first position under the pulling action of the safety belt. The front side is the side of the connecting seat away from the back of the seat body.

[0011] Preferably, the end of the connecting end of the safety belt has a connecting piece matched with the buckle.
