Abstract
The invention relates to an automotive chair headrest adjusting mechanism for adjusting forward, backward and wing angles. The mechanism comprises a headrest forward-backward translational electric adjusting mechanism and a headrest both-wing angle manual adjusting mechanism, wherein the headrest both-wing bracket of the headrest both-wing angle manual adjusting mechanism and the headrest front bracket of the headrest forward-backward translational electric adjusting mechanism are clamped and fixed together. The automotive chair headrest adjusting mechanism disclosed by the invention has the advantages that the automotive chair headrest adjusting mechanism is novel in structure, and synthesizes the headrest forward-backward translational electric adjusting mechanism and the headrest both-wing angle manual adjusting mechanism and systematically integrates four-directional adjusting mechanisms, thereby providing the maximum possible comfortableness for passengers; the forward-backward translational distance of a headrest can reaches 60mm, and compared with the traditional headrest without forward-backward adjustment and a headrest with forward-backward positions adjusted through rotating, the translational distance of 60 mm can maximumly meet the comfortableness requirements of different headforms; and the adjustment on two wings can meet the support of the headrest to the head when a passenger has a rest.
Description
Technical field
But the present invention be a kind of realize level can before and after the car seat headrest adjusting mechanism of electronic adjustment and both wings front and rear angles hand adjustment.
Background technology
Flourish along with automobile industry, people have higher requirement to the traveling comfort of automotive seat.Car seat headrest is as product comparatively special in the automotive seat, and except the security functions that possesses the protection human body head, people also require it to possess higher traveling comfort.Different people have also proposed adjustable requirement to the front and back position of car seat headrest, and the women who for example plaits one's hair requires headrest to regulate or the like backward; Along with the raising of seat comfort, recently people have higher requirement, promptly the occupant rest the head in bed flank can before and after rotate to support the head of human body.
Actually rare before and after having on the present global automotive seat market, only existing on high-end automotive seat with the chair headrest structure of flank angular adjustment.Their front and back position setting range, flank rotational angle setting range are almost consistent; That is to say that their traveling comfort almost is consistent.There is complex structure in existing these manual regulation car seat headrests, and expensive shortcoming is inappropriate on general car and promotes the use of.
Summary of the invention
The present invention provides before and after a kind of being used for and the car seat headrest regulating mechanism of flank angular adjustment, has complex structure to solve existing manual regulation car seat headrest, costs an arm and a leg, is inappropriate for the problem of on general car, promoting the use of.
The technical scheme that the present invention takes is: comprise headrest front and back translation motorized adjustment mechanism and headrest both wings angle manual adjustment means, headrest two wing supports of headrest both wings angle manual adjustment means connect and fix together with the headrest front carriage of the front and back translation motorized adjustment mechanism that rests the head on;
The structure of translation motorized adjustment mechanism is before and after the described headrest: head rest pole is fixed on the headrest middle bracket through 2 elastic cylindrical pins; Motor passes through 3 screw retention on the headrest middle bracket; Motor output shaft is a leading screw; Through nut leading screw is captiveed joint with the headrest front carriage, 3 rack frames connect and fix together with the headrest front carriage respectively, and these 3 rack frames are formed three groups of pinion and racks through corresponding 3 gear wheel shafts respectively with the headrest middle bracket; 4 rotating shaft pincers connect and fix together with back cover respectively, and gear wheel shaft connects together through rotating shaft pincers and the back housing assy that is made up of rotating shaft pincers, back cover;
The structure of described headrest both wings angle manual adjustment means is: left and right sides both wings are symmetrical mechanism; Existing is that example describes with the left wing: inlay rotating shaft in two wing supports of resting the head on; Bloated riveting nut is riveted on the card spring, and card spring and rotating shaft are rotationally connected, and the flank header board is captiveed joint with the card spring through the screw and the riveting nut that expands; Flank back cover and flank header board connect and fix together, and two wing supports of resting the head on connect and fix together with the headrest front carriage.
Advantage of the present invention is a novel structure, front and back motorized adjustment mechanism that combines headrest and headrest both wings angle manual adjustment means, the system integration four way control mechanism, the traveling comfort of maximum possible is provided for the occupant.The front and back translation distance of headrest can reach 60mm, and the headrest of regulating front and back position is rotated in headrest and utilization that comparing tradition does not have front and back to regulate, and translation 60mm can satisfy the people's of different head dummys traveling comfort requirement to the full extent.Headrest was to the support of head when the adjusting of both wings can be satisfied occupant's rest.
The 60mm that moves forward is very thorny for the layout of part for headrest, if headrest is done as a whole moving forward, is that the intensity and the inner structure of the headrest of 100mm almost can't realize to thickness so; If back cover is motionless, after fore shell moved forward 60mm so, the integral thickness of headrest was 160mm; Monnolithic case seems again, and some is too fat to move thick and heavy, and through design cleverly, front and back are regulated and adopted pinion and rack; It is the half the of tooth bar miles of relative movement that gear wheel shaft moves distance, and back cover is connected with gear wheel shaft, like this fore shell 60mm that moves forward; The back cover 30mm that under the drive of gear wheel shaft, moves forward then; This structure has guaranteed that the position relation of each part is reasonable in the motion process, and has practiced thrift the space to the full extent, makes the complicated headrest profile of inner structure be unlikely to excessive.
The present invention adopts motor-driven, to the full extent for the passenger provides comfort feature, and general manual regulation, complicated, the effort of its method of operation, and motorized adjustment mechanism, the passenger only need press button, can realize that just the front and back translation of resting the head on regulates, and is easy and convenient.Translational controlling mechanism reliability and accuracy at an arbitrary position before and after motor-driven has also guaranteed.
Press the height that button comes the motorized adjustment headrest through the occupant, front and back position improves occupant's traveling comfort.The present invention is simple in structure, and is with low cost, and noise is low, and reliability is high, and traveling comfort is good, in durability test cycle, does well, and daily service free is safeguarded.
