Head-neck flank damping structure, safety headrest and child safety seat

Abstract

The invention discloses a head-neck flank damping structure, a safety headrest and a child safety seat. The head-neck flank damping structure comprises a flank supporting skeleton, a flank supportingpiece, a damping mechanism, a protecting cover and an energy absorbing piece; the flank supporting skeleton is connected with a headrest skeleton, the flank supporting piece is connected with the headrest skeleton, and the damping mechanism is arranged on the inner side of the flank supporting skeleton and comprises a frame structure arranged around and a damping groove formed in the frame structure; the protecting cover is arranged outside the flank supporting piece and connected with the flank supporting piece; and the inner side of the damping mechanism is covered with the energy absorbingpiece, a buffering cavity is formed between the protective cover and the flank supporting piece, and the buffering cavity communicates with the damping groove. The head-neck flank damping structure has the advantages that deformation of the energy absorbing piece is larger through forming of the damping groove, and the situation that the head hits a hard plate behind the energy absorbing piece, consequently, buffering is insufficient, and damage is caused is avoided.

Description

technical field [0001] The invention relates to the field of child safety seats, in particular to a head and neck side wing shock absorbing structure, a safety headrest and a child safety seat. Background technique [0002] At present, a safety seat is a seat specially designed for children of different weights or ages, installed in a car, and can effectively improve the safety of children in a car. Many existing car accidents are caused by side impacts, and most of the child safety seats on the market do not have side impact protection devices. When side impacts occur, they often cannot protect the children seated well. There are also some producers who have produced child safety seats with side protection, such as the patent: The side protection structure (publication number: CN204749903U) of a child safety seat for cars comprises a side wing foam board, a reverse side collision frame and an anti-side collision foam board, but the reverse side The impact frame is in the s...

Problems solved by technology

Many existing car accidents are caused by side impacts, and most of the child safety seats on the market do not have side impact protection devices. When a side impact occurs, the child seated is often not well protected.

There are also some producers who have produced child safety seats with side protection, such as the patent: The side protection structure (publication number: CN204749903U) of a child safety seat for cars comprises a side wing foam board, a reverse side collision frame and an anti-side collision foam board, but the reverse side The impact frame is in the shape of a straight plate, and the anti-side impact foam board is fixed on the anti-side impact frame. In an actual collision, only relying on the material of the anti-side impact foam board itself cannot fully buffer the impact of the side impact, and it will still be on the safety seat. The child in the chair is injured, and because the straight plate shape of the anti-side collision frame directly transmits the impact force of the collision, the child may collide back and forth between the frames on both sides, causing secondary injury
