Further technical scheme of the present utility model is: described safety device comprises security framework, back board, rotating stand, connector bushing, connecting panel, described back board is fixed on the bottom of security framework, rotating stand is rotatably connected on the crossbeam at seat back-rest framework top, one end of connector bushing is fixed on the top of security framework, the other end passes the bottom that is socketed in connecting rod behind the rotating stand, described connecting panel one end is connected in the both sides of security framework by rivet, and the other end is connected with the both sides of seat back-rest framework by rotational pin.
Further technical scheme of the present utility model is: the U-shaped plate of described rotating stand for being made of a base plate and biside plate, have a through hole that passes for connector bushing on the base plate of this rotating stand, respectively have a pin-and-hole on the crossbeam that is enclosed within the seat back-rest framework top on the biside plate.
Further technical scheme of the present utility model is: described safety device also includes retracing spring, and an end of this retracing spring is connected on the connecting panel, and the other end is connected with the middle part of seat back-rest framework.
Because adopt said structure, the seat SAHR of the utility model compared with prior art has following beneficial effect:
1, simple in structure, cost is low:
Because safety device of the present utility model is the mechanical safety device that is connected with back of seat, it includes only security framework, back board, rotating stand, connector bushing, connecting panel and retracing spring, be to link together by connecting panel between security framework and the seat back-rest framework, its assembly technology is simple, do not need to increase electric apparatus and induction installation, therefore, of the present utility model relatively simple for structure, cost is lower, is suitable for promoting the use of in low and middle-grade vehicles.
2. safety performance is reliable:
The utility model is to utilize the mechanical movement principle, safety device is connected on the seat back-rest framework, human body impulsive force backward can activate the safety device of back of seat the inside when collision takes place, the back board of safety device moves backward, drive connector bushing, connecting rod rotate backward around the crossbeam of seat back-rest framework, headrest is moved forward, thereby can reduce the distance of head and headrest, the moment of head is supported the injury that can reduce cervical vertebra, thereby can provide the actv. safety control to driver and crew, its safety performance is very reliable.
3. can provide comfortable stable sitting posture to driver and crew:
What human body head and neck sustained damage when bumping because headrest and the distance of human body be more little may be just more low, but this may cause driver and crew's discomfort or fatiguability, and the present invention is installed in safety device in the back of seat, under normal circumstances, headrest and human body head are the distances that keeps suitable, only under situation about bumping, just can activate the safety device in the back of seat, headrest is moved forward, collision finishes the back headrest can get back to original position again under the effect of retracing spring, therefore, the utility model can provide comfortable stable sitting posture to driver and crew.
4. can guarantee the good looking appearance of back of seat:
Because safety device of the present utility model is mounted in the inside of back of seat, can not influence the good looking appearance of back of seat.
Below, the technical characterictic to the seat SAHR of the utility model is further described in conjunction with the accompanying drawings and embodiments.
