Description

Vehicle-mounted child safety seat

Technical Field

The invention relates to the field of child seats, in particular to a vehicle-mounted child safety seat.

Background

Safety measures such as safety belts and safety airbags on automobiles are basically designed according to the sizes and weights of adults, and the sizes and weights of children are different from those of adults, so that if the safety measures are directly used in emergency situations, injuries cannot be reduced, and injuries to the children are increased. Child safety seats have been designed to protect children.

With the further improvement of people's consciousness of riding safety, when child is less, child safety seat is fit for reverse installation and then makes child lie down, and child safety seat has great back, and child safety seat needs forward installation. Currently, in order to meet the demand of forward and backward mounting and riding of children, a rotatable seat can be adopted in a child safety seat for an automobile, and a seat body can rotate relative to a base, for example, when the child needs to ride forward, the seat body can be rotated to a forward position; when a rearward ride is desired, the seat body may be rotated to a rearward position. The invention patent of patent application number CN201510666754.5 (bulletin number CN 106585438A) discloses a child safety seat, which comprises a base, a seat main body, a rotating mechanism, a headrest and a lifting mechanism, wherein the rotating mechanism comprises a rotating disc arranged on the base, a rotating support and a limiting mechanism, the rotating disc is connected with the base through a rotating shaft, the rotating support is arranged on the rotating disc and can rotate along with the rotating disc, the limiting mechanism is used for limiting the rotation of the rotating disc, and the seat main body is arranged on the rotating support, so that the rotation of the child safety seat can be effectively realized, the base part rotates in the rotating process, and the rotation is quick and convenient.

The seat body of such child seats rotates relative to the base so that the seating area is supported differently for the child when switching between forward and rearward directions, i.e., seating in the forward direction and recline in the reverse direction. While current child seat chassis are constructed with a high rear front end low to adjust to a proper recline angle when installed in the direction of the seat body. However, there is a problem in that the seating surface inside the child safety seat is designed to be adapted to the seating state of the child, so that when a small infant is lying down, the seating surface forms a gap with the hip portion of the infant, and thus, a parent is generally required to pad the seating surface so as to better fit the child's body.

Disclosure of Invention

In order to solve the above problems, an object of the present invention is to provide a vehicle-mounted child safety seat, in which a height-adjustable airbag is disposed below a cushion body so as to accommodate children riding in different age stages.

In order to achieve the above purpose, the present invention adopts the following technical scheme:
