The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail: the utility model does not have special declaration, and the left side among Fig. 3 is the front side of child's safety seat for vehicle, and the right side among Fig. 3 is the back of child's safety seat for vehicle.
See Fig. 1～6, the child's safety seat for vehicle that a kind of height of headrest is adjustable, comprise the chair back 1 and headrest 3, offer groove 12 on the described chair back 1 along its long side direction, the described chair back 1 is respectively arranged with two row's projectioies 14 corresponding to the both sides of groove 12, is arranged at intervals with some grooves 10 respectively on this two rows projection 14.
The back of described headrest 3 is provided with projection 30, and this projection 30 is provided with 32, cross bars 5 of through hole and is located in the described through hole 32.When normal use, the two ends of this cross bar 5 are embedded in groove 10.Also promptly, rest the head on 3 height adjustments finish after its chair back 1 slippage relatively.
Be equipped with slide block 7 in the described groove 12, internal diameter and the internal diameter on groove 12 horizontal directions on described slide block 7 horizontal directions are suitable, internal diameter on groove 12 vertical direction is greater than the internal diameter on slide block 7 vertical direction, and in other words, described slide block 7 can be along these groove 12 upper and lower slippages.
One end of described slide block 7 is provided with baffle plate 72, and the other end is provided with screw rod 70, twists on this screw rod 70 and is provided with a knob 9.And described baffle plate 72 is fitted on the front side wall of headrest 3, and knob 9 is fitted in the back of the chair back 1.Thereby preventing to rest the head on 3 is separated with the chair back 1.
Preferably, also be provided with shrinkage pool 34 on the described headrest 3, the external diameter of described shrinkage pool 34 and baffle plate 72 are suitable, and the thickness of the degree of depth of this shrinkage pool 34 and baffle plate 72 is joined adaptive.When screwing knob 9, baffle plate 72 is flushed with headrest 3 like this.
Below principle of work is described in detail: when needs are regulated headrest 3 height, turning knob 9, headrest 3 is separated with the chair back 1, this moment, cross bar 5 also broke away from (specifically seeing Fig. 5) mutually with groove 10, to rest the head on then and 3 move to suitable position, and then screw knob 9, make cross bar 5 being embedded tightly specifically see Fig. 6 at groove 10(), rest the head on like this 3 just can not with the chair back 1 relative slippage.Thereby finish the control process of whole headrest 3.Operation is very easy.
