Abstract

The utility model provides a headrest adjusting mechanism of a child safety seat for a vehicle, which comprises the back of the seat and a headrest. The headrest is fixed on the back of the seat through a sliding mechanism, wherein the sliding mechanism comprises a positioning shaft, an operating part and a guide way; the guide way is fixed on the back of the seat; the guide way is provided with a plurality of grooves; the headrest is fixed on the operating part and moves on the back of the seat along with the operating part; the positioning shaft is fixed on the operating part, is erected in the grooves of the guide way of the back of the seat, is separated from or entered the grooves through the operation of the operating part, and moves along with the movement of the operating part. The headrest adjusting mechanism has the following advantages that: as the headrest is fixed on the back of the seat in a sliding way, the height thereof can be flexibly adjusted, so that the headrest adjusting mechanism can meet the requirement of children with different ages and heights for the height of the headrest, can conform to actual use, and is convenient in operation since the height of the headrest can be adjusted by a spanner.

Description

The head rest adjusting mechanism of child's safety seat for vehicle

Technical field

The utility model relates to a kind of child safety seat, particularly a kind of head rest of child's safety seat for vehicle.

Background technology

General and the chair body of the head rest of existing child's safety seat for vehicle is linked to be an integral body, so the stationkeeping of itself and seat is constant, can not adjust.Because difference, the difference at age and the ontogeny degree difference of ethnic group, the children's of each department, various countries all ages and classes section height difference, change more, therefore immutable head rest is difficult to satisfy all kinds of children's actual needs, presses for a kind of child's safety seat for vehicle that can conveniently adjust the head rest width of design.

Summary of the invention

Technical problem to be solved in the utility model is the head rest adjusting mechanism that a kind of child's safety seat for vehicle is provided for the above-mentioned deficiency that overcomes prior art, and the height by adjusting head rest is to satisfy the variation of children's height.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

The head rest adjusting mechanism of child's safety seat for vehicle comprises the chair back, head rest, and described head rest is fixed on the chair back slidably.

Above-mentioned head rest is fixed on the chair back by slide mechanism, slide mechanism comprises fix shaft, operating parts, guide rail, guide rail is fixed on the chair back, establish several grooves on the guide rail, described head rest is fixed on operating parts and moves on the chair back with operating parts, and described fix shaft is fixed on the operating parts, and frame is in the groove of chair back guide rail, and by operating parts operation and leave or enter in the groove, and move and move with operating parts.

When needs are adjusted the position of head rest,, make fix shaft leave the groove of guide rail and move and move with operating parts by operating parts operation fix shaft, the head rest that is fixed on simultaneously on the operating parts also moves, during to correct position, decontrol operating parts, fix shaft resets and falls into another groove of guide rail.

Above-mentioned guide rail has two, two guide rails are separately fixed at two sides of the chair back, establish several grooves on each guide rail, described fix shaft center fixed is on operating parts, and two end framves are in the groove of the chair back two side rails, and leave or enter in the groove by the operating parts operation, and move and mobile with operating parts, such structure is owing to adopt fix shaft two ends location, the more balance of exerting oneself when slip-on head leans on, mobile also more steady, then more firm and stable behind the location.

Aforesaid operations spare is preferably spanner, pins and can operate with hand, and is therefore very convenient.

Compared with prior art, advantage of the present utility model is:

Because head rest is fixed on the chair back slidably, therefore head rest can be adjusted its height flexibly, can satisfy the needs of the wide children of all age group and different bodies to the head rest height, more can realisticly use, and adjust the height of head rest by wrench operated, entire mechanism is easy to operate.

Description of drawings

Fig. 1 takes the lead structural representation by the child's safety seat for vehicle of adjusting mechanism for the utility model embodiment.

Fig. 2 is the back view of the utility model embodiment head rest adjusting mechanism.

Fig. 3 is the structural representation during the utility model embodiment head rest adjusting mechanism is adjusted.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, the head rest adjusting mechanism of child's safety seat for vehicle comprises the chair back 1, head rest 2, and head rest 2 is connected by spanner 3 with the chair back 1.

As shown in Figure 2, the above-mentioned chair back 1 two sides are fixed two guide rails 7, establish several positioning grooves 71,72 on each guide rail 7, and the distance that positioning groove is 71 is decided according to actual conditions such as head rest adjustment intervals, establish a guide rod 11 in the middle of the chair back 1, guide rod 11 2 sides are two guiding grooves 12,13.

About above-mentioned spanner 3 has two, connect by anchor shaft 5, and be installed on the head rest 2 by anchor shaft 5, spanner 3 can rotate with anchor shaft 5 like this.

5 of anchor shafts are on guide rod 11, and spacing head rest 2 makes head rest 2 move on the chair back 1 with spanner 3.

Fix shaft 4 center fixed are on spanner 3, and fix shaft 4 two end framves are in the positioning groove 71,72 of guide rail, and it breaks away from spanner 3 or enters in the positioning groove 71,72, and moves with spanner 3.

Torsion spring 6 is enclosed within on the anchor shaft 5, and one end 61 is positioned on the fix shaft 4, and the other end 62 is positioned on the spanner 3.

Above-mentioned safety strap 8 fixed head are leaned on 2, can adjust safety strap 8 simultaneously when adjusting head rest like this.

When adjusting safety strap and head rest position, elder generation to inner rotary, makes spanner 3 fix shaft 4 break away from positioning grooves 71,72, then spurs head rest 2 and moves up and down in the guiding groove 12,13 of the chair back, sees Fig. 3.

When head rest 2 moves to correct position, unclamp spanner 3, under the effect of torsion spring 6, fix shaft 4 just falls into positioning groove 71,72 and makes head rest 2 location, has realized the adjustment of the position and head rest 2 positions of safety strap 8.

Spanner 3 is symmetrical arranged and middle connects by fix shaft 4, balancing run more, and the head rest location is more stable, reliable.
