Description
Technical field
The invention belongs to automotive upholstery manufacturing technology field, specifically, relate to a kind of motor vehicle seat back and automatic adjusting method thereof.
Background technology
Automotive seat are important component parts of automotive upholstery, are also one of important safety components of automobile, and the quality of seat directly has influence on the safety of chaufeur.
Generally, automotive seat comprise front-row seats and back seat, and a little seven manned vehicles are also divided into front-row seats, middle row seat chair and back seat etc.Front-row seats comprises headrest, backrest, cushion, and back seat comprises the parts such as backrest, cushion, flank.
In daily life, a lot of drivers, before driving, often can ignore the position of adjusting in advance driver's seat.In fact, correct vehicle driving posture can effectively be protected driver's safety, if seat position is improper, will affect pilot's line of vision and the sensitivity controlled, even causes traffic accident, hurt own and other people.
Therefore the first thing before driving is exactly the height that will adjust driver's seat.Correct height of seat should be adjusted to driver's sight line and can not blocked by bearing circle, and can clearly see all important instrument and street sign indicator.After adjusting the height of seat, also to adjust the front and back position of seat.First buttocks should be leaned on as far as possible backward, best to push up between cushion and the chair back, can make like this oneself to sit more surely, can not rock.Should note the position of hand, pin after occupying stably, right-hand man is placed on respectively to the position at bearing circle 9 and 3 o'clock, now cannot allow the back of oneself leave the chair back, if left, represent you sit lean on very much after, seat must be moved forward.Other two hands are slightly crooked, when contingency has an accident like this, can effectively disperse impact, avoid strength to concentrate on each joint of arm.
Have at present in the average family that car rides instead of walk, mostly only have an automobile as walking-replacing tool, but often couple have driver, all need frequent steering vehicle, and everyone driving habit is different, there is following many deficiencies in seat of the prior art:
1, because seat of the prior art does not have memory mediation function, the chaufeur of different driving habits is when steering vehicle again, all need the driving habit according to oneself, the factors such as height, readjust the position of seat, the angles of backrest etc., bring certain trouble to the operation of chaufeur, lack convenience and traveling comfort.
