Description
Technical field
The present invention relates to a kind of chair headrest, especially relate 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 objective of the invention is to overcome above-mentioned deficiency, a kind of chair headrest regulating mechanism with four way control function and spinfunction about the front and back is provided.
The object of the present invention is achieved like this: 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.
Among the present invention, 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.
Among the present invention, 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 invention 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 present invention 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 invention has the beneficial effects as follows: 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 invention.
Fig. 2 is the exploded drawings of Fig. 1.
Fig. 3 is the structural representation of pivot arm part of the present invention.
Among the figure: headrest 1, support 2, fix screw I3, bearing pin I4, bearing pin II5, last pivot arm 6, following pivot arm 7, sliding bar 8, rubber pad 9, sliding support 10, fixing screw 11, back of seat 12, fix screw II13, bearing pin III14, nut III15, nut II16, nut I17.
The specific embodiment
Referring to Fig. 1～2, the band four way control function that the present invention relates to and the novel seat rest regulating mechanism of spinfunction mainly are made up of support 2, last pivot arm 6, following pivot arm 7, sliding bar 8 and sliding support 10.Described support 2 usefulness fix screw I3 are fixedly connected on headrest 1 back side, described pivot arm 6 upper ends of going up are rotationally connected by bearing pin I4 and nut I17 and described support 2 back sides, described pivot arm 6 lower ends of going up are rotationally connected by bearing pin II 5 and nut II16 with following pivot arm 7 upper ends, described down pivot arm 7 lower ends are rotationally connected by bearing pin III14 and nut III15 and described sliding bar 8 upper ends, be set with rubber pad 9 on the described sliding bar 8, described sliding bar 8 is inserted in the groove of sliding support 10, and with fixing screw 11 positioning and fixing, described sliding support 10 usefulness fix screw II13 are captiveed joint with back of seat 12 back sides between the sliding bar 8.
As shown in Figure 3, the pivot arm 6 of going up of the present invention is made of two arc-shaped connecting rods, and following pivot arm 7 is made of three arc-shaped connecting rods.Two arc-shaped connecting rods of last pivot arm 6 link to each other with three arc-shaped connecting rods of following pivot arm 7 are staggered.
