The invention provides a force-limiting child safety seat. The force-limiting child safety seat comprises a seat body, straps, a force-limiting buckle and winding devices. The force-limiting buckle isconnected with the straps on the two sides through a first transverse strap and a second transverse strap correspondingly. When the impact force is too large, the force-limiting buckle is opened, andthe straps on the two sides are wound through the winding devices. The force-limiting child safety seat further comprises a front protection body. A safety airbag is installed in the front protectionbody and can be ejected from a safety airbag tear line of the front protection body to fill in a gap between the front protection body and the legs of a child. The force-limiting child safety seat isreasonable in design, the sitting comfort of the child is ensured, and the situation that a great squeezing force is applied to the chest of the child by a safety belt when the impact force is too large is effectively avoided; and the safety of the child is guaranteed when a collision happens to a vehicle, and the child is not prone to being thrown out of the safety seat.
Description
technical field [0001] The invention belongs to the technical field of child safety seats, in particular to a force-limiting child safety seat. Background technique [0002] Currently, safety seats are widely used. When a vehicle collides, the auxiliary restraint system can effectively absorb part of the energy and fix the child in the safety seat, thereby effectively preventing the child from being thrown out of the safety seat. In the event of a frontal collision, the injuries to children in the collision are significantly reduced. [0003] The latest European car crash safety standard ECE R129 regulations have been fully implemented since 2018. The new regulations have made new requirements for children's abdominal pressure limit. my country's current collision safety regulations refer to the European ECE R44 standard, and will definitely refer to ECE in the future R129 is updated accordingly. In the event of a frontal collision, the child occupant receives an impact for...
