Description
Technical field
The utility model relates to a kind of chair headrest, especially relates to a kind of chair headrest regulating mechanism.Belong to automobile and electric wheel-chair vehicle accessory technical field.
Background technology
Because people's height difference, the headrest on the back of seat and the contact position of person neck are also inequality, and uncomfortable sitting posture causes cervical spine injury easily.Existing seat is provided with the height of headrest regulating mechanism usually.Automobile driver health in long-time vehicular drive process is easy to generate fatigue, and for the individuals with disabilities, and long-time uncomfortable sitting posture even may cause spinal injury causes the secondary injury.For alleviating driving fatigue, existing seat is provided with the mechanism at the scalable elevation angle, discloses a kind of adjustable automotive headrest frame as Chinese patent CN2839032Y, and chaufeur can be regulated the headrest elevation angle according to self needs.Different because of custom in addition, people's head rest is also different in the position of headrest, and some people likes keeping sight to look squarely, thereby earlier, and some people likes lying and leans against on the backrest, after then relatively leaning on.The regulating mechanism of existing seat does not possess this function usually on the market.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of chair headrest regulating mechanism with four way control function and spinfunction about the front and back is provided.
The purpose of this utility model is achieved in that a kind of chair headrest regulating mechanism with four way control function and spinfunction, it is characterized in that described regulating mechanism comprises support, last pivot arm, following pivot arm, sliding bar and sliding support, described support is fixedly connected on the headrest back side, the described pivot arm upper end of going up is rotationally connected with bearing pin I with described cradle back, the described pivot arm lower end of going up is rotationally connected with bearing pin II with following pivot arm upper end, described pivot arm lower end down and described sliding bar upper end are rotationally connected with bearing pin III, be set with rubber pad on the described sliding bar, described sliding bar is inserted in the groove of sliding support, and use the fixing screw positioning and fixing between the sliding bar, described sliding support is captiveed joint with the back of seat back side.
In the utility model, be rotationally connected by bearing pin III as upper and lower two pivot arms of attaching parts and sliding bar as connecting element, attaching parts can rotate around connecting element.Be rotationally connected by bearing pin II equally between two pivot arms.Do adjustment between rotation and two pivot arms by two pivot arms around sliding bar, before and after can realizing resting the head on, the four way control of high and low position.
In the utility model, last pivot arm and support are rotationally connected by bearing pin I.Rotate the adjusting at the elevation angle of can realizing resting the head on around bearing pin I by headrest.
Sliding bar of the present utility model can slide up and down in the sliding support groove.When the adjusting of the upper-lower position of being done around the position adjusting shaft by pivot arm is not enough to satisfy user's needs, can come the height of auxiliary adjustment headrest by the position of regulating sliding bar.
The utility model arbitrarily slides up and down in the sliding support groove in order to prevent sliding bar, by fixing screw sliding bar is fixed in the sliding support, and by spacing rubber pad prevent sliding bar since gravity to lower slider.
The beneficial effects of the utility model are: this chair headrest regulating mechanism can regulate at the people of different heights, different customs headrest about, front and back position and the elevation angle, and simple in structure, reasonable in design, simple operation, with low cost.
Description of drawings
Fig. 1 is an overall structure scheme drawing of the present utility model.
Fig. 2 is the exploded drawings of Fig. 1.
Fig. 3 is the structural representation of pivot arm part of the present utility model.
