[0002] On the car seat, the seat belt is wound on the winding shaft, and the stretching of the seat belt is realized through the winding of the winding shaft. The seat belt includes the shoulder belt part and the waist belt part on the left and right sides, and the shoulder belt part and the waist belt part on the same side It can be set in one piece, and lock buckles are arranged on the shoulder belt part and the waist belt part of the integral setting. A locking part matched with a pair of lock buckles, the locking part can be used as a crotch belt, when the car seat is in use, a child sits in the car seat, and the pair of lock buckles are fastened with the locking part, so that the safety belt is positioned on the small The child's shoulders, waist, and the locking piece are positioned on the child's crotch. In order to make the seat belt tightly fasten the child, the seat belt cannot be stretched but can only be contracted after the buckle and the locking piece are fastened. After the buckle is separated from the locking member, the safety belt should be able to stretch and shrink. In the existing safety belt restraint locking structure, an additional pull belt needs to be provided. After the buckle and the locking member are engaged, Then manually tighten the drawstring, so that the seat belt cannot be stretched, but can only be contracted. After the buckle is separated from the lock, the drawstring is released, so that the seat belt can be stretched and contracted. After the buckle and the locking part, the operation is cumbersome due to the need to pull the pull strap additionally. Moreover, if you forget to pull the pull strap, the seat belt cannot be fastened to the child, which is prone to safety accidents

The invention discloses a restraining and locking structure of a safety belt on a vehicle seat, which comprises a coiling shaft, a safety belt, a fastener, a locking part and an automatic locking mechanism, wherein the coiling shaft is rotatablely arranged on the vehicle seat; the safety belt can be coiled around the coiling shaft; the fastener is arranged in a position where the safety belt can be uncoiled from the coiling shaft; the locking part is used for being buckled with or separated from the fastener; and the automatic locking mechanism is used for enabling the safety belt only to be coiled around the coiling shaft but not to be uncoiled when the locking part and the fastener are buckled, and is also used for enabling the safety belt to be coiled and uncoiled around the coiling shaft after the locking part and the fastener are separated. By using the automatic locking mechanism, the safety belt can only be coiled but can not be uncoiled around the coiling shaft as long as the locking part and the fastener are buckled, and the safety belt can be coiled around the coiling shaft until the safety belt ties up a child fast. The safety belt can be tightened to tie up the child fast without any additional operation, thereby realizing convenient operation and eliminating potential safety hazard. After the locking part and the fastener are separated, the automatic locking mechanism unlocks the safety belt, and the safety belt can be coiled and uncoiled around the coiling shaft, i.e. the safety belt can be freely stretched or retracted.
