Description

A kind of child safety seat for automobiles head rest arrangement for adjusting height

Technical field

The utility model relates to a kind of child safety seat for automobiles, particularly relates to a kind of head rest arrangement for adjusting height of child safety seat for automobiles.

Background technology

Child safety seat for automobiles is a kind of special safety device for all ages and classes section or build designed for children, is installed in the automobile, can effectively improve children's seat of safety by bus.Automobile bump or the situation of slowing down suddenly under, can reduce children's impulsive force and restriction children's health are moved the harm that reduces them.As improvement, a handle is set on the seat, seat can be removed and be placed on the go-cart frame like this, serves as children trolley and uses.

Common child safety seat for automobiles comprises base, backrest and is located at the head rest that leans against top or upper end that head rest can support children's head.The head rest of generally seeing with lean against one-body molded or captive joint, can not regulate relatively, yet the growth of child development phase is very fast, obviously, unalterable head rest height is difficult to adapt to different children's health requirement.

Based on this, the adjustable child safety seat for automobiles of a lot of head rests is disclosed in the prior art, as the patent No. is Chinese utility model patent " the child's safety seat for vehicle " (Granted publication number: CN2887661Y) of ZL200620101165.9, head rest in this patent adopts a kind of slide mechanism to be connected with leaning against, and this slide mechanism adopts convex tendon and detent to cooperate and realizes regulating height; And for example the patent No. is that (Granted publication number: CN201240292Y), this patent is by realizing the head rest height adjustment with the lever push type for the Chinese utility model patent " automobile children safety chair head rest regulating mechanism " of ZL200820037452.7.Yet above-mentioned disclosed head rest regulating mechanism structure is comparatively complicated, and stability is not good enough again, needs to improve.

The utility model content

Problem to be solved in the utility model is at the above-mentioned state of the art, to provide a kind of simple in structure, easy to adjust, the child safety seat for automobiles head rest arrangement for adjusting height that the state stability behind the head rest height adjustment is good.

The utility model at the technical scheme that above-mentioned technical matters adopts is:

A kind of child safety seat for automobiles head rest arrangement for adjusting height, comprise lean against, head rest and, regulating control is located at and is leaned against and can move up and down, the bottom has two slide openings being herringbone and one to leaning against the galianconism that stretch out at the rear; Two latches, L-shaped, first end of two latches is close to each other and stretch out and be positioned at the slide opening of regulating control respectively to the regulating control front, and second end is located in the horizontal concrete chute of regulating control below, and can move along horizontal concrete chute; And spring, be located between two latches and be positioned at horizontal concrete chute;

Lean against and have a plurality of slots that cooperate with the latch dismountable type on the short transverse, be under the no external force state, first end of latch is positioned at the uppermost position of slide opening, and the afterbody of second end cooperates with slot.

Further, lean against the pilot hole that horizontal direction is arranged in juxtaposition two hollow outs, accordingly, head rest is provided with a pair of director that matches with pilot hole.

Further, each director comprises director and following director, and horizontal concrete chute is up and down between the director.

Further, head rest middle part is provided with two parallel guiding ribs leaning against on the short transverse, and this guiding rib and can move up and down in the guide groove that regulating control forms between guiding rib between director.

Further, the button cover plate that the regulating control back side is provided with button and matches with button, button is captiveed joint with the galianconism of regulating control, and the button cover plate is captiveed joint with director.

Further, the regulating control upper end is provided with a slide opening, has one on the head rest and is positioned at slide opening and limits the limiting stopper that slide opening breaks away from head rest.

Compared with prior art, advantage of the present utility model is: promote button, first end of latch is drawn close to the centre along pilot hole, makes the afterbody of latch second end break away from the slot that leans against, continue to promote button, then the head rest height changes, after the adjustment, and release button, latch is under the effect of spring, first end separates along pilot hole, and the afterbody of second end then inserts corresponding slot, and the head rest height just redefines like this.Easy and simple to handle, integral structure is simple and practical, again in combination relatively firmly, is difficult for throwing off behind latch and the slot location.
