Abstract

A shoulder rest adjusting mechanism of a child safety car seat comprises a chair back, a pair of shoulder rests and a pair of guide tracks, wherein the guide tracks are respectively fixed on two sides of the chair back, the shoulder rests are equipped with guide blocks which are disposed between the guide tracks, the guide tracks are connected by a double-parallelogram connecting rod engine, a meshed clutch mechanism is arranged between each guide block and each guide track and controlled by a pull rod fixed on the guide block, and one end of the pull rod extends out one side of a seat body. The shoulder rest adjusting mechanism has the advantages that the width of the shoulder rests of a child safety car seat can be flexibly adjusted because of the shoulder rest adjusting mechanism, requirements on the width of shoulder rests for children at different ages and with various width can be met, which is practical. Further, the whole device is convenient in operation because the distance between the shoulder rests can be adjusted by the pull rod arranged on two sides of the child safety car seat.

Description

The shoulder rest adjusting mechanism of automobile children safety chair

Technical field

The utility model relates to a kind of child safety seat.

Background technology

The shoulder rest of existing automobile children safety chair generally is to be linked to be an integral body with the chair 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 shoulder have narrow have wide, change more, and because the variation that how much also can cause the shoulder size that children wear the clothes, therefore immutable shoulder rest is difficult to satisfy all kinds of children's actual needs, presses for a kind of automobile children safety chair that can conveniently adjust the shoulder rest width of design.

Summary of the invention

Technical problem to be solved in the utility model is the shoulder rest adjusting mechanism that a kind of automobile children safety chair is provided for the above-mentioned deficiency that overcomes prior art, changes requirement to this by its width of adjusting shoulder rest to satisfy children's shoulder.

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

The shoulder rest adjusting mechanism of automobile children safety chair, comprise the chair back, a pair of shoulder rest, pair of guide rails, pair of guide rails is separately fixed at two sides of the chair back, described shoulder rest band guide block, guide block places between guide rail, and two guide rails are connected by two parallelogram connection-rod machines, and meshing type engaging and disengaging gear is set between guide block and guide rail, meshing type engaging and disengaging gear is by the pull bar operation that is fixed on the guide block, and pull bar one end stretches out chair body one side.

Described engaging and disengaging gear comprises lock dog, the eccentric block of band saw tooth up and down, settles retracing spring between lock dog and guide rail, and eccentric block is enclosed within on the pull bar.

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

Owing to be provided with the shoulder belt adjusting mechanism, so the shoulder rest of automobile children safety chair can adjust its width flexibly, can satisfy the needs of the wide children of all kinds of ages and different bodies to the shoulder rest width, more can be realistic.And can adjust distance between shoulder rest by the pull bar that is arranged on automobile children safety chair two sides, therefore whole device is easy to operate.

The specific embodiment

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

According to Fig. 2, shown in Figure 3, guide rail 4 is fixed on the chair body 12, adjustable shoulder rest 1 band guide block 11, and its guide block 11 places in the guide rail 4, and can move on the P1 direction, thereby shoulder rest is moved on the P1 direction.

Pull bar 3 and pull bar 8 are installed in respectively by briquetting 5 on the guide block 11 of adjustable shoulder rest 1 on two limits, and can rotate on the P2 direction.

Handle 2 is fixed on an end of pull bar 3 by axle 21, can rotate foldingly around axle 211, can fold up handle 2 when complete operation, takes up room reducing, and prevents to have influence on bystander person.

As shown in Figure 3, Figure 4, link together with two parallelogram linkages 7 between the guide block 11 of two adjustable shoulder rests 1, parallelogram linkage is fixing by tween drive shaft 72, when the adjustable shoulder rest in the left side when the P3 direction spurs, the adjustable shoulder rest on right side can and then move towards the P4 direction, and vice versa.

Adopt the solid existing interlock of the equilateral polygon collar between pull bar 3 and the pull bar 8, as Fig. 6, when pull bar 3 rotated, pull bar 8 also can and then rotate, and vice versa.

Between the guide block 11 of shoulder rest and guide rail engaging and disengaging gear is set, engaging and disengaging gear is by pull bar 3 and pull bar 8 operations.

Eccentric block 31 is set on the pull bar 3, and eccentric block links to each other with latch segment 6 about in the of 31, and the tooth 61 of latch segment 6 is relative with the tooth 41 of

guide rail

4, and 11 of latch segment and guide blocks are provided with retracing spring 10.

When pull bar 3 turns to as shown in Figure 5 position, because the effect of eccentric block 31 involute circular arcs, promote its up and down latch segment 6 side shifting outwardly of both sides, the sawtooth 61 of latch segment 6 is embedded in the sawtooth 41 of guide rail 4, shown in the amplifier section T of Fig. 4 and the Y shadow region of Fig. 5, thereby define adjustable shoulder rest moving on the P1 direction.

When pull bar 3 turns to as shown in Figure 6 position, because the combined action of leaving of retracing spring 10 deboosts and eccentric block 31 involute circular arcs, the latch segment 6 that promotes both sides inwards moves, the sawtooth 61 of latch segment 6 is left in the sawtooth of guide rail 4, thereby pulling pull bar 3 can drive adjustable shoulder rest can move freely on the P1 direction.
