Specific embodiment
As shown in figures 1-4, a kind of child safety seat back support construction is arranged on child safety seat, for delaying
Rush the impact force that infant back is subject to, seat back portion of the back-supported structure setting in child safety seat.
Seat back portion includes seat back pad 1 and headrest, and on the positive top of seat back pad 1, headrest is fixed with seat back pad 1 for headrest setting
Connection.
For back-supported structure setting at the back side of seat back pad 1, back-supported structure includes headrest knob 2, and headrest knob 2 is set
It sets at the back side of seat back pad 1, headrest knob 2 is fixedly connected with seat back pad 1.
2 middle part of headrest knob is provided with support slot 8, vertical supporting spring 9 is provided in support slot 8, support spring 9 is used for
Play the role of buffering lifting force when 2 adjusting height of headrest of headrest knob, headrest knob 2 is whole to pull seat back pad 1 to lower to go up
The height of head restraint.
The lower part of headrest knob 2 is provided with supported hole 3, and two sides are provided with fixation hole 4 in supported hole 3.
Be provided with support base 5 in supported hole 3, the two sides of support base 5 are provided with convex block 6,5 two sides of support base it is convex
Block 6 is separately positioned in corresponding fixation hole 4.
Spring 7 is provided in support base 5, one end of spring 7 is arranged in support base 5, the other end and chair of spring 7
The back side of back pad 1 is in close contact.
Fixation hole 4 is set as triangle, and the area size of fixation hole 4 is greater than the cross-sectional area of 5 two sides convex block 6 of support base
Size.
The working principle of the present embodiment are as follows: when infant rides on child safety seat, back-supported structure by
The pressure that human body applies, support base 5 move in the fixation hole 4 of delta-shaped region, and spring 7 carries on the back human body by after active force
Portion applies reaction force, and infant back is made to obtain powerful support, and it is excessively hale and hearty to be unlikely to back, causes discomfort.
When infant is movable in child safety seat, when infant sways forwards and backwards body, back-supported structure is frequent
By the active force that human body applies, spring 7 constantly absorbs and releases the back that active force is applied to infant, plays buffering and makees
With being unlikely to the back impacting of infant to the seat back portion of hale and hearty child safety seat, make the back of infant from hitting
Bring injury.
When driver take emergency braking or occur traffic accident when, infant's meeting under the action of automobile inertial
It leans forward, under the constraint effect of child safety seat band, clenches infant, infant is not made to be detached from children's peace
Full seat, when automobile is after emergency braking or generation traffic accident, infant can make under the reaction force by safety belt
Infant springs back in child safety seat, at this time when infant touches child safety seat back, back-supported structure
Especially spring 7 plays the role of buffer function power to the back of infant, reduces impact force of the infant by seat back portion, protects
It demonstrate,proves infant in this case, any danger does not occur.
Other technologies are referring to the prior art.
The above is only preferred embodiments of the present invention, is not the limit to technical solutions of the utility model
It is fixed, it is noted that those skilled in the art can also make further under the premise of technical solutions of the utility model
Improvement and change, these improvement and change should all be covered within the protection scope of the present utility model.
