2) because the adjusting button or the regulating handle of the headrest height adjustment device of automobile children safety chair often are arranged on the seat rear side, there is the defective of inconvenient operation;
3) also the height of headrest adjusting knob can be arranged on seat tops or left and right side, reach the purpose that height of headrest is regulated by positive and negative turn knob, what but this type of mechanism often adopted is that screw thread screws mechanism, efficient is very low in the height of headrest control process, and regulate often wastes time and energy very much;
4) existing child safety seat on the market also needs manual regulation shoulder belt height after height of headrest is regulated, complicated operating process not only, and the user also carries out maloperation easily, has great potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of height of headrest of automobile children safety chair and regulates
Device, this device need not when driving child safety seat to be regulated after the tightening state release of safety belt for vehicle or ISOFIX again, and be easy to operate, safe.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of headrest height adjustment device of automobile children safety chair, comprise the chair back and the headrest that is positioned at described chair back front side, this device also comprises the slide plate that can move up and down along the described chair back that is positioned at described chair back front side, the upper end of described slide plate is connected with the activity box that is used for fixing described headrest, be provided with the elastic plate that is used for described activity box homing between described slide plate and the described activity box, the back side of described activity box is provided with the hook-type link span, inlay card has metal screens axle in the groove of described hook-type link span, the back both sides of the described chair back are provided with the screens piece, described screens piece is provided with a plurality of screens grooves that match with described metal screens axle, the back side of described slide plate is set with screens axle orienting lug, described screens axle orienting lug is positioned at the rear side of the described chair back, and described screens axle orienting lug is provided with the described metal screens of a plurality of confessions axle chute of slide relative back and forth.
Described chute is horizontally disposed with.
Described chair back bilateral symmetry is provided with the shoulder belt guide groove that moves up and down for shoulder belt, described slide plate both sides are vertically arranged with and the corresponding shoulder belt perforation in the position of described shoulder belt guide groove, and described shoulder belt passes described shoulder belt perforation by described metal screens axle and is fixed on the described chair back.
Described elastic plate is positioned at the same side of described slide plate and described activity box.
Described elastic plate is a spring plate.
Described activity box and described slide plate adopt the toughened plastic material.
The cross-sectional plane of described activity box is an arc.
Compared with prior art, advantage of the present utility model is: when using external force to pull the upper end of headrest forward, activity box produces clockwise rotatablely moving, drive the hook-type link span simultaneously and carry out equidirectional rotatablely moving, thereby driving metal screens axle moves laterally along chute, the restriction while metal screens axle that makes metal screens axle break away from the screens groove on the screens piece is limited in avoids metal screens axle to break away from the hook-type link span in the chute, make slide plate be in the state that freely to move up and down, make elastic plate be in the flexural deformation state simultaneously, the pulling headrest discharges the external force that puts on headrest top after reaching the position that needs up or down, activity box is the conter clockwise motion under the effect of the natural restoring force of elastic plate, make headrest be close to the chair back once again, drive the hook-type link span simultaneously and carry out return motion, thereby driving metal screens axle moves to the inside along chute, metal screens axle is dropped in the corresponding screens groove, make whole headrest mechanism be in locking state, to reach the function that height of headrest is regulated.
Because the chair back vertically is symmetrically arranged with two rectangular shoulder belt guide grooves, shoulder belt is along with the space of up-down adjustment when can be used as the headrest up-down adjustment, the slide plate both sides are vertically arranged with and the corresponding shoulder belt perforation of shoulder belt guide groove, shoulder belt acts on total system by metal screens axle and the shoulder belt hole passed on the slide plate, when headrest carries out height adjustment, metal screens axle and shoulder belt hole are that the height of following headrest is synchronized with the movement, thereby the drive shoulder belt can be followed the height of metal screens axle and be carried out up-down adjustment, can be with the self-regulating function of height of headrest to reach the shoulder belt height.
Therefore; the headrest height adjustment device of a kind of automobile children safety chair of the utility model is regulated the height of headrest easily under the running condition of child safety seat; need not when driving child safety seat is regulated after the tightening state of the tightening state of safety belt for vehicle or ISOFIX discharges again; and the user can arbitrarily be in the left side or the easy and convenient adjusting of right side realization of child safety seat; with the person's head lateral protection when driving that provides the child seats at any time; automatically drive the height adjustment of shoulder belt when headrest is realized height adjustment simultaneously, simplified because of the variation of children's height reconfiguring the trouble that the shoulder belt height is brought greatly.
