Description
Technical field
The present invention relates to a kind of child safety seat that car uses more particularly to a kind of ventilative vehicular child safety seats
Chair.
Background technique
The safety belt carried in automobile is designed by adult, and 140 centimetres of height, 36 kilograms of weight or more are only applicable to
Child, for the children not yet sound for the development of the height bodily form, if only using safety belt on vehicle, when a collision occurs, peace
Full band is possible to the danger for causing fracture of rib, asphyxia even neck to fracture to children.For this purpose, automobile children safety chair is met the tendency of
And give birth to, have more than 50 years history so far, many countries require that 6 years old or less children must sit safety when riding in an automobile
Seat.
However presently commercially available various child safety seats have the imperfect disadvantage of gas permeability, summer children are taking
When, back is easy to perspire because scorching, and the fabric of some children's seats, cushion use ventilative material thus, but due to lacking
Active ventilating mechanism, permeability are limited.
Disclose " a kind of air-bag type formula ventilating system application No. is 201810084421.5 Chinese invention patent application
Child safety seat " (publication No. CN108116278A), including seat body and ventilating system, the ventilating system installation
Inside the backrest portion of the seat body, the backrest portion outer wall of the seat body is equipped with dismountable sealing cover；It is described
Seat body inner surface coated with bonded scrim material；It is equipped between the bonded scrim material and the seat body logical
General mood bag layer offers air hole, and the air inlet of the ventilation airbag layer and the ventilating system on the ventilation airbag layer
Air outlet be connected.The ventilating system includes blower and guide duct, one end of the guide duct and the blower phase
Even, the other end is connected with the air inlet of the ventilation airbag layer.The ventilating system, can using blowing by the way of,
It can also be by the way of air draught.The ventilating system can be double outlet single-fan systems, be also possible to two fans system.
The patent application uses blower as power, and uses air-bag type structure, and air is made to form circulation in airbag again
Seat surface is exported to, thus ventilation quantity is larger and is evenly distributed, so that solution efficiently solves child safety seat in the chair back
On ventilating problem.But in practical applications, automobile rear seat position is generally not provided with power outlets, can only be from vapour
The cigar lighter of vehicle operation bench goes out to take electricity, thus necessarily has conducting wire to pass through front-row seats to back seat, using having inconvenience, furthermore more
Blower can also generate additional noise, can be obvious in closed environment inside car, it is often more important that, which does not have
The back for being easiest to perspire for children provides Design of ventilation.
Summary of the invention
First technical problem to be solved by this invention be for above-mentioned state of the art and provide it is a kind of can be to multiply
The children back of seat provides the ventilative automobile children safety chair sufficiently divulged information.
Second technical problem to be solved by this invention is to provide one kind and also can guarantee good lead to without external power supply
The automobile children safety chair of wind permeability.
The technical scheme of the invention to solve the technical problem is: a kind of ventilative automobile children safety chair,

Air-flow is allowed uniaxially to flow to the outlet side of ventilation component from air bag.
In order in actual use, the air bag be made to have more chances to be squeezed and supplied, and also to
The movable plate can be effectively limited, downwardly projecting bearing bulb, institute can be provided in the bottom surface center of the movable plate
Corresponding position is provided with bearing ball and socket base on the seat stated, to accommodate and allow bearing bulb one way or another wherein
Deflection；In this way, due to the effect of inertia, being sitting in emergency seat when automobile has acceleration, deceleration or turning action in the process of moving
Children's torso on chair can swing back, lean forward or inclination movement, movable plate run-off the straight therewith, to be pressed into place in it
Under air bag.
In order to make the air bag provide more outlets, the air bag can have multiple and be evenly arranged on the seat
On, it is generally preferred with four, in matrix pattern around the bearing ball and socket base；In this way, automobile have every time acceleration, slow down or
Turning action and after restoring normally travel, all at least corresponding two air bags in back and forth or left and right are extruded and supply；
The elastic component can be set within the air bag, also can be set except the air bag, and described
Accordingly, the elastic component is spring to four air bags, there are four and be separately positioned on the outside of corresponding air bag；The spring
To be preferred using Pagoda-shaped spring, just sets or be inverted, the work for resetting the movable plate upwards can not only be played in this way
With, also to make movable plate under external force be easier run-off the straight；
The elastic component, which can also be, to be set in the bearing bulb and supports the spring except ball and socket base, at this point,
Spring in air bag or outside air bag, which can be omitted, not to be had to.
As long as the ventilation component is to guarantee there are venting channels in it, there can be various forms, most simply, can adopt
With compound ventilation form of tubes, it is divided into leading portion, interlude, back segment three parts along airflow direction, wherein leading portion is located at the activity
In gap between plate and the seat of the seat body, son pipe identical as air bag number including quantity and mutually parallel (as
Inlet end above-mentioned), the air inlet of every preceding cross-talk pipe is connected with the gas outlet of corresponding air bag, the outlet side of each preceding cross-talk pipe
It is gathered together and is connected with interlude, the end branch of interlude is each parallel sub- pipe (as outlet side above-mentioned), is formed
The back segment, the back segment are located on the chair back of the seat body, are provided with venthole on the rear cross-talk pipe.
It can also include to be arranged described to make interlude and the back segment of the compound snorkel not be exposed at front
Backing before the seat body chair back has the shape to match with the chair back of seat body, the back segment of the compound snorkel
It is located at after backing, the venthole is elongated and is provided on the leading flank of each rear cross-talk pipe, and the backing
