Further, described seat cushion upper side is evenly distributed with several cool fiber boss points.
Further, described seat cushion downside is provided with rubber layer with anti-skidding.
Further, waist holder is provided with bottom described back pad.
By such scheme, the present invention at least has the following advantages: one, and head protector flank can form safety precaution to head and vertebra, and in head protector flank buffer mouth, expanded polyethylene foam is formed without bone buffer protection simultaneously, and the good and good permeability of expanded polyethylene foam elastic force is to avoid the danger suffocated; Two, the opening that surrounds of described " C " type flak jacket flank and backrest and be filled with expanded polyethylene foam in opening, such setting can ensure that children are when crash flank, forms comformability deformation buffering, the bone that available protecting children are more tender; Three, rest the head on scalable with adjust height, side band can through differing heights positioning perforation adjust side band use height to adapt to the children of different height; Four, seat support both sides are respectively equipped with handrail and handrail is provided with storage trough, and handrail can prevent children side from sitting, in order to avoid there is the danger that side band causes child chest fracture of rib, the even neck that suffocates fractures; Storage trough can place the carry-on little article of children to strengthen functions of seat and practicality; Five, the child that child's chair cushion can adapt to 9-18 kilogram uses when taking, because child's skull is more tender, elastic shock attenuation block and buffer zone define territory, header buffer, when can ensure automobile generation strong collision or emergency brake like this, child's head plays the effect of safety precaution in order to avoid child's head injuries when springing back to the headrest.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification sheets, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
