Anti-loose safety belt of child seat

Abstract

The invention relates to the technical field of children's safety belts, and discloses an anti-loose safety belt for children's seats, which includes a node lock, a lower webbing, a lock tongue, an upper webbing and a fixing buckle, and the upper webbing passes through the lock tongue The connection section between the rear and the fixed buckle is provided with a telescopic safety mechanism. In the present invention, by adding a telescopic safety mechanism to the chest and shoulder section of the upper webbing belt, the safety belt can provide a section of telescopic self-tightening section, so that the child's body can move freely within the range of the telescopic section, and the telescopic length can be guaranteed. Children cannot be separated from the shackles of the seat belt to provide children with a comfortable and safe riding experience. The air pressure in the inner cavity should not increase or decrease instantaneously, so that in the event of an accident such as a car collision, the slider will not have a large displacement, that is, the length of the seat belt will not change, thereby effectively ensuring the safety of the child.
