Description
Technical field
Field of automobile seats is the utility model is related to, more particularly to one kind headrest power seat.
Background technology
Automotive headrest is a kind of driver comfort configuration articles for use and security protection articles for use, when vehicle knocks into the back, human body
Since inertia can fall backward, the pressure of vehicle acceleration or deceleration all concentrates on neck and the head of human body fragility at this time, and rests the head on
Cushioning effect is then played to this, protects human body head.In way is travelled, the spacing between hindbrain and headrest is the smaller the better.In this way, chase after
The cushioning effect to neck can be played when hitting.
Because the driving habit of people is different, so everyone is also different for the position of seat and the angular adjustment of backrest.
For seat, somebody's custom is forward, so can more accurately estimate the distance in headstock and front.Somebody is accustomed to rearward, this
Sample can have the activity space of bigger.The front and back position of seat, the height for headrest are influential, if forward, headrest
Height can become higher, if backward, the height of headrest can be lower, both of which cannot be guaranteed that headrest plays people protection and makees
With so, it is necessary to which the height of headrest is adjusted after the front and back position of seat is adjusted.
Because everyone height is different, but whether height how, upper body and lower part of the body trunk are proportional.
For example seat is previously that one 1 meter 9 of people adjusted, one 1 meter 5 of people is allowed to adjust seat, lower part of the body trunk is short, and seat needs past
Front slide, to adapt to the human-machine operation of steering wheel and accelerator and brake, same upper body trunk breaks to be moved downward, it is necessary to rest the head on so that
The center of headrest and the center of the back side of head are in the same horizontal line.
Existing headrest either adjusts headrest or automatic adjustment headrest manually, is required for manually being operated, operates
Get up and inconvenient, so, vast majority of people often neglects this point.And people can not possibly be always maintained at phase on running car way
Same sitting posture, so, the distance between hindbrain and headrest of people are also change.
