Description
Technical field
The present invention relates to a kind of seat, specifically a kind of headrest regulating device.
Background technique
The shoulder belt hole of conventional child safety seat is fixed, will be from former shoulder belt hole when adjusting seat shoulder belt
Shoulder belt is unloaded, then penetrates another row's shoulder belt hole, it is cumbersome, time-consuming and laborious.And the shoulder belt of child safety seat is with head now
The lifting leaned on is adjusted together, and head rest is adjusted mainly with pull rod chamfered structure, by the elasticity of spring, keeps the gear axis on head rest de-
Shelves card shelves are achieved in the adjustable of head rest, and drive mechanism is complicated, and components are more, manufacture, is at high cost, spring cooperation
Assembling is difficult, and spring stability in use and service life have hidden danger.
Summary of the invention
The present invention provides a kind of simplified structures, reduce components, reduce the cost and difficulty of manufacture and assembling, and raising makes
With the headrest regulating device of safety and service life.
The technical solution adopted by the present invention is that: a kind of headrest adjusting device, including head rest knob, head rest knob, which is worn to connect, to be supported
It is against on the head rest on chair back front in limit liftable driving status, it is characterised in that: further include head rest locator, head rest is fixed
Position device is placed in chair back rear portion, is linked up with across chair back clasp joint on head rest in the middle part of head rest locator, and head rest shakes hands lower part across chair
Back is arranged towards the chair back, inclined skewback, the setting of head rest locator top upward corresponds to the cammed surface against skewback inclined-plane, head rest
The two sides of locator top cammed surface are equipped on the corresponding clamping chair back positioning tooth of two column gear slots from top to bottom, head rest locator
Lower elastic pushes against the chair back.
Further, it wears and connects on head rest through rotary shaft rotation in the middle part of the head rest locator.
Further, the two sides of head rest locator top cammed surface are equipped on the corresponding clamping chair back two column from top to bottom
The locating rod of gear slot.
The present invention in use, head rest knob is pulled to make the inclined-plane uplink pusher head of its underpart by locator top cammed surface,
Since head rest locator connects on head rest through its upper hook, head rest locator top after by thrust back rotation determine upper part
Position tooth or locating rod disengage the clamping with gear slot on the chair back, and head rest locator disengages the connection with the chair back, pull head rest knob
Synchronous drive head rest moves up and down the adjusting for completing head rest, and it is inclined-plane and the oblique cooperation of cammed surface that head rest knob, which pulls lifting displacement,
The projected length on head rest knob direction of displacement of length, head rest knob pull lifting inclined-plane not disengage with cammed surface；It adjusts
Unclamp head rest knob afterwards in place, head rest locator top rotates forward under the return action power that its underpart elasticity pushes against the chair back,
Positioning tooth or locating rod on head rest locator are caught in the positioning after realizing head rest adjusting in gear slot, and overall structure simplifies,
Components are reduced, and the cost and difficulty of manufacture and assembling reduce, and are effectively improved using the safe and service life, and head rest positioning uses bullet
Piece rotates around mounting point, elastic compression joint structure, can further ensure that stability in use and service life.
Detailed description of the invention
Fig. 1 is head rest of the present invention knob and head rest locators structural schematic diagram；
Fig. 2 is adjustment state structural schematic diagram of the present invention.
In figure: the chair back 1, head rest 3, head rest knob 4, skewback 5, head rest locator 6, hook 7, cammed surface 8, is determined gear slot 2
Position tooth 9.
Specific embodiment
It is described further below in conjunction with drawings and examples.
Fig. 1, shown in 2: a kind of headrest adjusting device includes head rest knob 4 and head rest locator 6, and head rest knob 4, which is worn, to be connect
It is resisted against on the head rest 3 on 1 front of the chair back in limit liftable driving status, head rest locator 6 is placed in 1 rear portion of the chair back, head rest
6 middle part of locator passes through chair back clasp joint on head rest 3 through hook 7, and 4 lower parts of head rest knob pass through the chair back and are arranged towards the chair back, court
Upper inclined skewback 5, the corresponding cammed surface 8 against 5 inclined-plane of skewback of 6 top of head rest locator setting, 6 top of head rest locator are oblique
The two sides of wedge surface are equipped on the corresponding clamping chair back positioning tooth 9 of two column gear slots 2 from top to bottom, and head rest locator lower part is elastic
Push against the elastic rib structure of the chair back.
