Description
Technical field
The invention belongs to technical field of manufacture of automobile upholstery, specifically, relate to a kind of motor vehicle seat back
And automatic adjusting method.
Background technology
Automotive seat is the important component part of automotive upholstery, is also one of important safety component of automobile,
The quality of seat directly influences the safety of driver.
Under normal circumstances, automotive seat includes that front-row seats and back seat, a little seven passenger cars are also divided into
Front-row seats, middle row seat chair and back seat etc..Front-row seats includes headrest, backrest, medicated cushion, rear row seat
Chair includes the parts such as backrest, medicated cushion, flank.
In daily life, a lot of drivers, before driving, often ignore the position of first Row sum-equal matrix driver's seat
Put.In fact, correct vehicle driving posture can effectively protect the safety of driver, if seat position is improper,
The sensitivity of pilot's line of vision and manipulation will be affected, even result in vehicle accident, hurt oneself and other people.
Therefore the first thing before driving seeks to adjust the height of pilot set.Correct height of seat should
The sight line being adjusted to driver will not be blocked by steering wheel, it is possible to clearly see all of important instrument and
Street sign indicator.After adjusting the height of seat, position before and after seat to be adjusted.First should be by buttocks
Lean on backward as far as possible, with top to best between medicated cushion and the chair back, so can make oneself to sit more steady, will not rock.
After occupying stably it should be noted that hand, the position of foot, is individually placed to steering wheel 9 and the position at 3 o'clock right-hand man
Putting, the back of oneself now cannot be allowed to leave the chair back, if left, representing that you sit too rearward,
Seat must be moved forward.Other two handss slightly bend, and time so just in case having an accident, can effectively disperse
Impact force, it is to avoid strength concentrates on each joint of arm.
Have in the average family that car is ridden instead of walk at present, mostly only have an automobile as walking-replacing tool, but often
Couple are owned by driver, be required for often driving vehicle, and everyone driving habits is different, existing
With the presence of the following many deficiencies of the seat in technology:
1, due to seat of the prior art, not there is memory mediation function, the driving of different driving habitses
The factors such as member, when again driving vehicle, is required to the driving habits according to oneself, height, readjust seat
The position of chair, the angle etc. of backrest, bring certain trouble to the operation of driver, lack convenience and relax
Adaptive.
2, not having memory mediation function due to seat of the prior art, different drivers are driving again
When sailing vehicle, need to readjust seat, but the angles and positions adjusted often be difficult to accurately grasp, it is impossible to
It is rapidly reached optimum position, expends regular hour and energy.
Summary of the invention
The technical problem to be solved is, adjusts owing to seat of the prior art does not have memory
Solving function, the driver of different driving habitses, when again driving vehicle, is required to the driving according to oneself and practises
Used, the factor such as height, readjust the position of seat, the angle etc. of backrest, bring to the operation of driver
Certain trouble, lacks convenience and comfortableness；When driver readjusts seat, the angle of adjustment and position
Put and be often difficult to accurately grasp, it is impossible to be rapidly reached optimum position, expend the technology such as regular hour and energy
Problem, and provide a kind of motor vehicle seat back and automatic adjusting method thereof.
The technology design of the present invention is, owing to seat of the prior art does not have memory mediation function,
The driver of different driving habitses, when again driving vehicle, all readjusts the position of seat, the angle of backrest
Degree etc., bring certain trouble to the operation of driver, lack convenience and comfortableness；Adjust seat simultaneously
Angles and positions be often difficult to accurately grasp, it is impossible to be rapidly reached optimum position, expend the regular hour and
The technical problems such as energy, the invention provides a kind of mechanism automatically adjusting seat according to memory, including gravity
Induction system and correction system, when different drivers drive vehicle again, by being arranged under Chain cushion
Gravity sensing system, signal is passed to central control module, described central control module by correction system,
First confiring that whether have data memory, if having, and in critical field, then whether correction system detection seat
Consistent with data memory, if unanimously, then without adjusting, if inconsistent, then according to the last history number
According to being automatically adjusted.Thus, the driver of the different driving habitses effectively solved is driving vehicle again
Time, all readjust the position of seat, and the technical problem of accurate location can not be adjusted to rapidly.This technology
Design brings facility to different driver, is greatly improved the comfortableness of vehicle.
