In the such scheme, drive link one end is used to drive two rotating shafts, and the other end is provided with button, and button is arranged on the outside of backrest.
In the such scheme, two rotating shafts directly upwards also are respectively equipped with second pivoted arm, and drive link drives two rotating shafts rotation by promoting two second pivoted arms.
In the such scheme, the rotating shaft drive end of drive link is provided with block, and drive link promotes two second pivoted arms by block.
In the such scheme, drive link is provided with and is used for the spacing limited block of drive link.
The utilization of the utility model device be the principle of connecting rod transmission, drive two rotating shafts simultaneously by drive link, thereby finish the release of two backstays and two alignment pins.
Compared with prior art, the utlity model has following advantage:
1, the passenger only uses the singlehanded release that drive link just can be realized head rest that drives, and the another hand can be used to regulate the head rest height, and is easy to operate.
2, an end of drive link is provided with button, and button is arranged on the outside of backrest, convenient control to drive link.
3, the transmission mechanism between drive link and the rotating shaft is simple, is operated in good stability.
4, drive link is provided with and is used for the spacing limited block of drive link, can be the sports limiting of connecting rod, rotating shaft, alignment pin, drive link simultaneously.
Description of drawings

Fig. 2,3 is the structural representation of the utility model embodiment
Wherein: 1-button, 2-backstay, 3-drive link, 4-first pivoted arm, 5-connecting rod, 6-alignment pin, 7-block, 8-limited block, 9-rotating shaft, 10-torsion spring, 11-spacing hole, 12-second pivoted arm, 13-head rest, 14-backrest.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples:
As Fig. 1,2, shown in 3, the utility model headrest arrangement for adjusting height embodiment, it comprises two backstays 2 and is used for the retaining mechanism of lock in place bar 2, the upper end of backstay 2 links to each other with the head rest of seat 13, insert in the backrest 14 of seat the lower end of backstay 2, retaining mechanism is arranged in the backrest 14, have spacing hole 11 on the backstay 2, retaining mechanism comprises two alignment pins 6 that are used for locking respectively two backstays 2, be used for driving respectively two connecting rods 5 of two alignment pins, 6 releases, be arranged on two rotating shafts 9 on the backrest 14, be separately positioned on two rotating shafts, 9 footpaths two first pivoted arms 4 that make progress and the drive link 3 that is used for driving simultaneously two rotating shafts, 9 rotations.Alignment pin 6 is by inserting the spacing hole 11 lock in place bars 2 on the backstay 2.
One end of two connecting rods 5 is connected with two alignment pins 6 respectively, and the other end of two connecting rods 5 is hinged with two first pivoted arms 4 respectively; Overlap respectively in two rotating shafts 9 and be useful on the torsion spring 10 that resets; Connecting rod 5, rotating shaft 9, first pivoted arm 4 are arranged between two backstays 2, and drive link 3 is arranged between two rotating shafts 9.
