Description

The scalable head rest of child safety seat for automobiles mechanism

Technical field

The utility model relates to a kind of child safety seat for automobiles, relates in particular to the scalable head rest of a kind of child safety seat for automobiles mechanism.

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, leans against and is located at the head rest that leans against top or upper end, and 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 realizes the head rest height adjustment by a 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, installs and regulates trouble, and stability is not good enough again, needs to improve.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of easy to adjust, the scalable head rest of child safety seat for automobiles quick for installation mechanism at the above-mentioned state of the art.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the scalable head rest of a kind of child safety seat for automobiles mechanism, comprise lean against and the height can be located at the head rest that leans against the upper end with regulating, it is characterized in that also comprising

Adjusting yoke is located on the described head rest and can be moved up and down, and the bottom has two slide openings that are herringbone;

Latch, for a pair of, substantially L-shaped, first end can be located in the horizontal concrete chute of described head rest bottom with moving around, and second end is close to each other and stretch out and be positioned at the slide opening of aforementioned adjusting yoke respectively to the head rest front; And

Spring is located between the aforesaid latch and is positioned at horizontal concrete chute,

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

Lean against and the relatively moving preferably by following structure directing setting of head rest: describedly lean against the pilot hole that horizontal direction is arranged in juxtaposition two hollow outs, accordingly, described head rest is provided with the guide part that a pair of and aforementioned pilot hole cooperates.

Assembly relation between guide part and the pilot hole is preferably as follows design: described each guide part comprises director and the physical efficiency that will lead is located at the interior guide cover of pilot hole slidably.

For latch can stably be operated, consider that simultaneously assembling is compact, described director comprises director and descends director, described horizontal concrete chute is then on aforesaid between director and the following director.

Be convenient to moving up and down of adjusting yoke, described head rest middle part convexes with two parallel guiding ribs, and this guiding rib can move up and down in the guide groove that described adjusting yoke then forms between aforesaid guiding rib between guide part.

Be convenient to the adjusted pull bar, described adjusting yoke upper end is a handle portion for the finger application of force.

Be the excessive application of force of restriction adjusting yoke, described adjusting yoke middle part offers a slide opening, accordingly, has one on the described head rest and is positioned at aforementioned 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: the pulling adjusting yoke, second end of latch is drawn close to the centre along pilot hole, makes the afterbody of latch first end break away from the slot that leans against, head rest energy height up and down, after the adjustment, unclamp adjusting yoke, latch is under the effect of spring, and second end separates along pilot hole, the afterbody of first end then inserts corresponding slot, and head rest redefines with highly just leaning against like this.Easy and simple to handle, integral structure is simple and practical, installs also fast, has in combination relatively firmly behind latch and the slot location, is difficult for throwing off.
