Abstract
The utility model discloses an adjustable headrest for an automobile seat. The adjustable headrest comprises a left support saddle and a right support saddle which are used for mounting the headrest and are arranged at a spacing interval, wherein a long shaft is arranged between the left support saddle and the right support saddle by penetration, a front plate is fixedly arranged on the long shaft by penetration, a rear plate is further fixedly arranged between the left support saddle and the right support saddle through a short shaft, a big ratchet wheel is connected between the left support saddle and the front plate through a big ratchet wheel shaft, the lower end of the front plate is fixed with the big ratchet wheel shaft, the left support saddle is connected with a small ratchet wheel matched with the big ratchet wheel through a small ratchet wheel shaft, and a tooth head of the small ratchet wheel is matched with gear teeth of the big ratchet wheel for synchronously regulating the angles of the left and right support saddles in stages. The adjustable headrest disclosed by the utility model has the advantages of simple structure, more regulation gears, large angle regulation range and capability of resetting automatically after regulation.
Description
Technical field
The utility model relates to the vehicle body fittings technical field, and especially a kind of automotive seat are used headrest adjustable.
Background technology
At present, the headrest angle that the general vehicle seat is used is unadjustable, can not be according to passenger's needs adjustment headrest angle.And the headrest of general adjustable angle, regulation stall is less, and angle of regulation range is little, need manually set back complex operation after the adjusting.
The utility model content
The technical matters that the utility model will solve is: overcome the deficiency in the prior art, provide that a kind of regulation stall is many, angle of regulation range is big, can use headrest adjustable by automatically reset automotive seat after regulating.
The utility model solves the technical scheme that its technical matters adopted: a kind of automotive seat are used headrest adjustable; Comprise left support abutment and right support abutment that the spacing that is used to install headrest is provided with; Run through being provided with major axis between left support abutment and right support abutment, run through being fixed with header board on the major axis, also be fixed with the back plate between left support abutment and right support abutment through minor axis; Be connected with large ratchet through the megacanthopore wheel shaft between left support abutment and header board; Header board lower end and megacanthopore wheel shaft are fixed, and left support abutment is connected with the little ratchet that cooperates with large ratchet through little ratchet shaft, and the tooth head of little ratchet cooperates synchronous stepping to regulate left and right bearing angle with the large ratchet wheel tooth.
Be with an end and the large ratchet fixedly other end and the fixing torsion spring of header board on the megacanthopore wheel shaft, be connected with pendulum spring on the little ratchet, the pendulum spring other end then is fixed on the left support abutment.Have six wheels tooth on the large ratchet, clavula gear teeth head has two teeth.
The beneficial effect of the utility model is: the automotive seat that the utility model provides are used headrest adjustable, and are simple in structure, and regulation stall is many, angle of regulation range is big, can automatically reset after regulating.

The specific embodiment
Combine accompanying drawing that the utility model is further described now.The scheme drawing that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
Use headrest adjustable like Fig. 1 to a kind of automotive seat shown in Figure 3; Comprise left support abutment 1 and right support abutment 2 that the spacing that is used to install headrest is provided with; 2 of left support abutment 1 and right support abutments run through and are provided with major axis 3; Run through being fixed with header board 4 on the major axis 3,2 of left support abutment 1 and right support abutments also are fixed with back plate 6 through minor axis 5.4 of left support abutment 1 and header boards are connected with large ratchet 8 through megacanthopore wheel shaft 7, are with an end on the megacanthopore wheel shaft 7 and large ratchet 8 is fixing, the torsion spring 11 that the other end and header board 4 are fixed.Header board 4 lower ends and megacanthopore wheel shaft 7 are fixing, when left and right bearing 1,2 rotates, can drive megacanthopore wheel shafts 7 rotation simultaneously through header board 4.Left support abutment 1 is connected with the clavula wheel 10 that cooperates with large ratchet 8 through clavula wheel shaft 9, is connected with pendulum spring 12 on the clavula wheel 10, and pendulum spring 12 other ends then are fixed on the left support abutment 1.Have six wheels tooth on the large ratchet 8, clavula is taken turns 10 tooth heads and has two teeth.The tooth head of clavula wheel 10 cooperates synchronous stepping to regulate left and right bearing 1,2 angles with large ratchet 8 wheels tooth.
During work; Large ratchet 8 is fixed with the headrest intubate of automotive seat; The left and right bearing 1,2 that rotates backward, left and right bearing 1,2 drive clavula wheel 10 and clavula wheel shaft 9 motion backward together under the effect of pendulum spring 12, megacanthopore wheel shaft 7 also drives down at header board 4 and rotates backward.The revolution left and right bearing 1,2 that makes a movement, clavula wheel 10 is just up walked a tooth along the gear track of large ratchet 8, has six teeth on the large ratchet 8; Clavula is taken turns 10 tooth heads and has two teeth; Can realize the adjusting of five gears altogether, every adjusting is then rotated octave for one grade, altogether scalable 40 degree; Regulation stall is many, and angle of regulation range is big.When rotating left and right bearing 1,2 once more; This clavula wheel 10 arrives Neutral Position under the drive of left and right bearing 1,2; Pendulum spring 12 is owing to the tension of clavula wheel 10 produces screen resilience; The screen resilience of pendulum spring 12 drives clavula wheel 10 again and is returned to initial position, and left and right bearing 1,2 automatically resets.
Above-mentioned embodiment is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage that is familiar with this technology can understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
