Described fixing Kato part is connected with base by bolt, and base is provided with bar shaped bolt mounting groove, and bolt is positioned at bar shaped bolt mounting groove.
Described Liquid and gas damper can be replaced the water bumper and gas spring that are set up in parallel.
Described extension and contraction control unit adopts screw mandrel linear stepping motor as telescopic drive part; described screw mandrel linear stepping motor is arranged in fixing pillow by motor fixing frame, and the screw of screw mandrel linear stepping motor is connected by screw link span with between flexible protection pillow.
In described fixing pillow, be also provided with track runner, the screw mandrel of track runner and screw mandrel linear stepping motor be arranged in parallel, in track runner, be provided with guide rail, and guide rail one end is fixed on flexible protection pillow.
Described track runner and screw mandrel linear stepping motor and level are that angle is arranged.
Described extension and contraction control unit also can adopt electric pushrod as telescopic drive part, and described electric pushrod is arranged in fixing pillow by electric pushrod fixed mount, and the push rod head of electric pushrod protects pillow to be connected with flexible.
Described electric pushrod and level are that angle is arranged.
The beneficial effects of the utility model:
The extension and contraction control unit of seat of the present utility model by arranging in headrest; before generation of knocking into the back; extension and contraction control unit can respond fast; and drive flexible protection pillow to stretch out fast; when then stopping immediately after flexible protection pillow contact head, when rear-end impact occurs, due to flexible protection pillow stretch out reduce headrest and head between distance; and then reduce the horizontal displacement of head and neck, that reduces head gets rid of whip effect backward.The buffering energy-absorbing damping resilience unit of seat of the present utility model by arranging between base and backrest, when rear-end impact occurs, under effect of inertia, human body back can produce an application force backward to backrest, and yaw displacement is produced between base and backrest, be subject to the buffering energy-absorbing function of buffering energy-absorbing damping resilience unit, deflection kinetic energy and the deflection speed of backrest can be reduced, resilience is started after backrest reaches tilt limit, be subject to again the shock damping action of buffering energy-absorbing damping resilience unit, the rebound velocity of backrest can be reduced, and then reduce head get rid of forward whip effect.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, 3; a kind of seat that can prevent whiplash injury; comprise chair body and headrest; buffering energy-absorbing damping resilience unit is provided with between the base 1 and backrest 2 of described chair body; described headrest is arranged on backrest 2; headrest comprises fixing pillow 3 and flexible protection pillow 4, and flexible protection pillow 4 is connected by extension and contraction control unit and fixing pillow 3.
Described buffering energy-absorbing damping resilience unit comprises some Liquid and gas dampers 5 and fixing Kato part 6, and Liquid and gas damper 5 is arranged on base 1 by fixing Kato part 6, and piston rod and the backrest 2 of Liquid and gas damper 5 are hinged.
Described fixing Kato part 6 is connected with base 1 by bolt, and base 1 is provided with bar shaped bolt mounting groove 7, and bolt is positioned at bar shaped bolt mounting groove 7.
Described Liquid and gas damper 5 can be replaced the water bumper and gas spring that are set up in parallel.
Described extension and contraction control unit adopts screw mandrel linear stepping motor as telescopic drive part; described screw mandrel linear stepping motor is arranged in fixing pillow 3 by motor fixing frame 8, and the screw 9 of screw mandrel linear stepping motor is connected by screw link span 11 with between flexible protection pillow 4.
In described fixing pillow 3, be also provided with track runner 12, track runner 12 be arranged in parallel with the screw mandrel 10 of screw mandrel linear stepping motor, is provided with guide rail 13 in track runner 12, and guide rail 13 one end is fixed on flexible protection pillow 4.
Described track runner 12 and screw mandrel linear stepping motor and level are that angle is arranged.
As shown in Figure 4, described extension and contraction control unit also can adopt electric pushrod 14 as telescopic drive part, and described electric pushrod 14 is arranged in fixing pillow 3 by electric pushrod fixed mount 15, and the push rod head of electric pushrod 14 protects pillow 4 to be connected with flexible.
Described electric pushrod 14 is that angle is arranged with level.
Below in conjunction with accompanying drawing, a use procedure of the present utility model is described:
Vehicle of the present utility model is installed, in normal driving process, if the super sonic tachogenerator of vehicle tail detects that rear car has the possibility that knocks into the back, the very first time extension and contraction control unit of headrest will respond fast, for electric pushrod, electric pushrod stretches out fast and drives flexible protection pillow 4 to stretch out fast, when after flexible protection pillow 4 contact head, electric pushrod stops immediately, when rear-end impact occurs, due to flexible protection pillow 4 stretch out reduce headrest and head between distance, and then reduce the horizontal displacement of head and neck, that reduces head gets rid of whip effect backward.If rear-end impact does not occur, through after a period of time, electric pushrod returns initial position automatically, drives flexible protection pillow 4 to return initial position, achieves reusable object.
While rear-end impact occurs, under effect of inertia, human body back can produce an application force backward to backrest 2, and yaw displacement is produced between base 1 and backrest 2, owing to being connected to Liquid and gas damper 5 between base 1 and backrest 2, during beginning, backrest 2 pairs of Liquid and gas dampers 5 carry out compression, but be subject to the buffering energy-absorbing function of Liquid and gas damper 5, reduce deflection kinetic energy and the deflection speed of backrest 2, resilience is started after backrest 2 reaches tilt limit, but be subject to the shock damping action of Liquid and gas damper 5, again reduce the rebound velocity of backrest 2, thus, what reduce head gets rid of forward whip effect.
Through the double protection of extension and contraction control unit and buffering energy-absorbing damping resilience unit, farthest prevent the generation of whiplash injury.
Scheme in embodiment is also not used to limit scope of patent protection of the present utility model, does not allly depart from the equivalence that the utility model does and implements or change, and is all contained in the scope of the claims of this case.
