Description

Technical Field

[0001] The utility model relates to the technical field of child safety seats, in particular to a safety protection structure for child safety seats. Background Art

[0002] Child safety seats, also known as child occupant restraint systems, are devices designed for children of different weights that can effectively improve children's safety when riding in a car. In the event of a car collision or sudden deceleration, they can reduce the impact on children and limit the movement of children's bodies, thereby reducing injuries. They are compulsory certified products. As children's safety continues to receive attention, child safety seats suitable for children of different sizes have been developed. Installing child safety seats in cars plays a great role in reducing the death or serious injury of children in traffic accidents.

[0003] The Chinese patent publication number is CN207173365U, and the authorization announcement date is April 3, 2018. A child seat safety protection structure includes a seat back, a five-point safety belt, a first guard plate and a pop-up device, etc. The pop-up device can make the first guard plate, the second guard plate and the third guard plate pop out along the two first limit grooves and the second limit groove respectively, and form a protective barrier together with the front seat in the motor vehicle to protect children from being hurt by splashing objects. The lock tongue in the pop-up device contacts the hook under the action of the second return spring, so that the other end of the first return spring is inside the hook. At this time, the guard plate is not popped out. By pressing the push rod, the lock tongue is separated from the hook under the drive of the second return spring. At this time, due to the rebound force of the first return spring, the guard plate will be immediately popped out to form a barrier to protect children.

[0004] Existing child safety seats are usually larger than the child's body size. Children cannot fit completely when sitting in the child safety seat. There is no lateral protection structure on both sides of the seat. When hit by external force from the side, the child will collide with the seat again, causing secondary injury to the child, reducing the safety effect of the child safety seat and failing to meet usage requirements.
