Description
Technical field
The present invention relates to child safety seat field, more particularly to a kind of safety chair seats of car of turnover folding.
Background technology
Existing band ISOFIX interface child safety seats, backrest is linked from base using ISOFIX metal interfaces, because
For by EU criteria ECE R44/04 and Chinese national standard GB27887 requirements, wherein 1 group（9-18KG）P3 dummy's test must pass through
Misuse test（Drawstring can not be used）；Therefore the strength of whole seat crash impact is only born with two interfaces of base ISOFIX
It is very huge, the rising of production cost can only can so be caused by standard detection by seat bulk metal support.
Moreover, ISOFIX child safety seat is fixed mostly at present, between each part such as backrest and base mutually
Position is fixed, it is impossible to is folded so that the overall volume of child safety seat is larger, and transport and carrying are relatively difficult；Minority can
With the seat of folding, it is that multiple parts are such as rested the head on, backrest, handrail, cushion part are detachably connected between each other, but this gesture
The impact resistance of seat must be reduced, to overcome this problem majority seat to use metal part stent, although so
It can improve certain impact resistance, but in the junction of part and part, still easily be rolled over when withstanding shocks power
Disconnected phenomenon, security are relatively low.
In summary, reduce seat overall volume to provide one kind and can fold, and simultaneously there is sufficiently stable property to make
It can be by the seat of standard detection, and the applicant is special to propose a kind of safety chair seats of car of turnover folding.
The content of the invention
In order to overcome above mentioned problem, the invention provides a kind of safety chair seats of car of turnover folding.
To achieve the above object, technical scheme provided by the invention is：

It is provided with turning device, described seat cushion portion is arranged on the inner side of turning device, and the reverses direction of turning device is towards back-rest
The back side or seat cushion portion bottom surface so that the back side of back-rest can be forced to be in contact with the bottom surface in seat cushion portion, back-rest turns over
Turn the limit and at least meet two states, state one：Back-rest relies on the back in seat cushion portion completely；State two：Backrest is completely perpendicular
Stand in seat cushion portion；And when back-rest and cushion is erected in, the reverse flip of back-rest can be limited by automotive seat, works as backrest
Portion meets that seat cushion portion is erected on back-rest to the limit of seat cushion portion front upset, and can limit cushion part by automotive seat
Reverse flip, the stability of seat state is formed so as to ensure back-rest with seat cushion portion.
Detachable block installation bit position and non-mounting point are provided with described back-rest, and is pacified in detachable block
Circumferential force structure is provided with dress bit position, and is only provided with more than two reinforcement cage bars in non-mounting point.
Described reinforcement cage bar is axially arranged along back-rest, and triangular supports are provided between adjacent reinforcement cage bar.
The oblique reinforcement of one or more is symmetrically arranged with the outside of the reinforcement cage bar.
The bottom of at least one reinforcement cage bar is connected with inclined-plane reinforcing plate.
Supporting plate is additionally provided between the back-rest and seat cushion portion, one end of supporting plate is flexibly connected with back-rest,
The bottom of supporting plate contacts with seat cushion portion；It is provided with the supporting plate and slows down support.
The described support that slows down includes several triangular supports, and several triangular supports are uniformly set along supporting plate plate face
Put.
Described supporting plate is provided with two, and two supporting plates are located at the both sides of back-rest bottom respectively.
Described circumferential force structure is arranged on the junction of supporting plate and back-rest, and circumferential force structure is at least provided with three
Individual stress surface.
Above-mentioned technical proposal is beneficial in that：
The invention provides a kind of safety chair seats of car of turnover folding, and it is to realize back-rest and seat cushion using turning device
Portion can turn over folding, more convenient in transport or carrying process；And due to being set between back-rest and seat cushion portion
There are the parts such as circumferential force structure, main support, it can be ensured that seat cushion portion and the junction of back-rest still have excellent connection steady
It is qualitative, make seat that there is excellent impact resistance, can be in week when ISOFIX interfaces or safety seat carrying impulsive force
Cut down impulsive force in the presence of to force structure, main support, supporting plate and its some triangular supports, realize that efficient is moved
Amount be converted to momentum, reach momentum is kept to as far as possible 0 purpose；In addition, tested by the applicant, automotive safety of the invention
Seat in addition to trip shaft other can all adopt made of plastic, still can have excellent impact resistance, meet national mark
Standard, compared to existing metal safety seat, production cost is not only considerably reduced, more reduce the weight of seat, it is convenient
Installation, transport, carry.
