Abstract
The technical field of the utility model child safety seat; in particular to child safety seat head rest side crash protects system; the head rest includes head rest shell; arc head rest ontology is provided on the inside of head rest shell; the two sides of head rest ontology are provided with buffer body; the material of the head rest ontology is polystyrene foam (EPS), and the material of buffer body is polyurethane (PU).Child safety seat head rest side crash provided by the utility model protects system; when side impact occurs; impact force acts on buffer body PU; sponge most energy; it is transmitted on head rest ontology EPS later and sponges dump energy; it can more effectively be absorbed for head, disperse generated impact force when side impact, improve the safety of safety seat.
Description
Technical field
The utility model belongs to the technical field of child safety seat, in particular to child safety seat head rest side crash is protected
System.
Background technique
Automobile children safety chair is that one kind aims at all ages and classes (or weight) children design, is mounted in automobile, can have
Effect improves the seat of children riding safety, and as children's safety is constantly taken seriously, the technology of child safety seat is obtained
It rapidly develops.
Existing automobile children safety chair head rest is simple polystyrene foam (EPS) material, does not have side anticollision
Protection system；Using this child safety seat, when side collision occurs, seat side cannot preferably be inhaled
Energy caused by hitting is received, and generates different degrees of injury to the head of children, therefore is needed in the market a for head
Portion can more effectively absorb, disperse the lateral protection system of generated impact force when side impact.
Utility model content
The purpose of the utility model is to provide a kind of child safety seat head rest side crash to protect system, can more have for head
The absorption of effect disperses generated impact force when side impact.
Purpose of the utility model is realized as follows: a kind of child safety seat head rest side crash protects system, the head
Support includes head rest shell, is provided with arc head rest ontology on the inside of head rest shell, the two sides of head rest ontology are provided with buffer body, institute
The material for stating head rest ontology is polystyrene foam (EPS), and the material of buffer body is polyurethane (PU).
Installation through-hole is provided on above-mentioned head rest ontology, buffer body is arranged in installation through-hole.
Above-mentioned buffer body may be configured as arbitrary shape, it is preferred that above-mentioned buffer body is ellipse, the radian of inner surface
It is consistent with head rest ontology.
The lateral ends of above-mentioned installation through-hole are provided with semicircular limited block, are provided with and limit on the lateral wall of buffer body
The step structure that position block matches.
Several first installation grooves are provided on the lateral wall of above-mentioned head rest ontology, if being provided on the lateral wall of buffer body
The second installation groove is done, several installation raised lines, first installation groove, the second installation are provided on the inner sidewall of head rest shell
Groove is matched with installation raised line.
Above-mentioned first installation groove, the second installation groove and installation the horizontally-parallel setting of raised line, the first installation groove and
Second installation groove is connected.
Compared to the prior art the utility model, has the following beneficial effects:
The buffer body of polyurethane (PU) material is mounted to the head rest sheet of polystyrene foam (EPS) material by the utility model
In body, and it is fixed on head rest shell jointly.When as padded coaming, the cushion performance of PU is better than EPS.It is hit when side occurs
When hitting, impact force is acted on buffer body PU, sponges most energy, is transmitted to head rest ontology EPS later, by by head
Support ontology EPS, which is pressed on head rest shell, sponges remaining energy.After the side anticollision protection system of the utility model buffering
The strength on child head is acted on, just the head rest than common EPS material is much smaller, to enhance the safety of child safety seat
Property.

Fig. 4 is the perspective view of the utility model buffer body.
Appended drawing reference: 1, head rest shell；2, head rest ontology；3, buffer body；11, raised line is installed；21, installation through-hole；22, it limits
Position block；23, the first installation groove；31, step structure；32, the second installation groove.
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1-4:
A kind of child safety seat head rest side crash protects system, and the head rest includes head rest shell 1, head rest shell 1 it is interior
Side is provided with arc head rest ontology 2, and the two sides of head rest ontology 2 are provided with buffer body 3, and the material of the head rest ontology 2 is polyphenyl
Vinyl foam (EPS), the material of buffer body 3 are polyurethane (PU).
Above-mentioned buffer body 3 may be configured as arbitrary shape, it is preferred that above-mentioned buffer body 3 is ellipse, the arc of inner surface
Degree is consistent with head rest ontology 2.
When installation, buffer body 3 is installed into head rest ontology 2, then buffer body 3 and head rest ontology 2 are fixed on head together
It holds in the palm on shell 1.Buffer body 3 is located at the position that children head is in contact with head rest side, when side collision occurs, head first with
Buffer body 3 contacts, and buffer body 3 sponges most energy, and head rest ontology 2 absorbs dump energy later, due to the buffering of PU
Performance is better than EPS, therefore the head rest cushion performance for being provided with buffer body 3 is enhanced.
The specific structure of above-mentioned installation is:
Installation through-hole 21 is provided on above-mentioned head rest ontology 2, buffer body 3 is arranged in installation through-hole 21.Installation through-hole 21
Shape it is consistent with buffer body 3.
The lateral ends of above-mentioned installation through-hole 21 are provided with semicircular limited block 22, are arranged on the lateral wall of buffer body 3
There is the step structure 31 matched with limited block 22, step structure 31 is mounted on limited block 22.
It is provided with several first installation grooves 23 on the lateral wall of above-mentioned head rest ontology 2, is arranged on the lateral wall of buffer body 3
There are several second installation grooves 32, several installation raised lines 11, first installation groove are provided on the inner sidewall of head rest shell 1
23, the second installation groove 32 is matched with installation raised line 11.It is convex by the first installation groove 23, the second installation groove 32 and installation
Head rest ontology 2 and buffer body 3 are installed to corresponding position by the cooperation of item 11, are reused fixing piece later and are fixed.
