Description

A kind of automotive seat and its automatic adjusting method
Technical field
The invention belongs to technical field of manufacture of automobile upholstery, specifically, it is related to a kind of automotive seat and its automatic tune Adjusting method.
Background technology
Automotive seat is the important component of automotive upholstery, is also one of important safety component of automobile, seat Quality directly influences the safety of driver.
Under normal circumstances, automotive seat includes front-row seats and back seat, and a little seven passenger cars are also divided into front row seat Chair, middle row seat chair and back seat etc..Front-row seats include headrest, backrest, cushion, and back seat includes backrest, cushion, flank Deng part.
In daily life, many drivers ignore the position of adjustment driver's seat in advance before driving, often.Its Real, correct vehicle driving posture can effectively protect the safety of driver, if seat position is improper, driver will be influenceed to regard Line and the sensitivity of manipulation, even result in traffic 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 be adjusted Sight to driver will not be blocked by steering wheel, it is possible to clearly see all important instrument and street sign indicator.Adjusting After the height of whole good seat, the front and back position of seat is also adjusted.Buttocks should backward be leaned on as far as possible first, cushion and chair are arrived to push up Between the back of the body preferably, it can so make oneself to sit more steady, will not rock.After occupying stably it should be noted that hand, the position of pin, or so Hand is individually placed to the position at 9 and 3 o'clock of steering wheel, now the back of oneself cannot be allowed to leave the chair back, if leaving, table Show that you sit too rearward, it is necessary to which seat is moved forward.Other two hands outline microbend, can be effective when so accident occurs for contingency Dispersing impact forces, it is to avoid strength is concentrated on each joint of arm.
Possess at present in the average family that car is ridden instead of walk, an only automobile is as walking-replacing tool mostly, but often man and wife Both sides are owned by driver, are required for often driving vehicle, and everyone driving habit is different, and seat of the prior art is deposited In following many deficiencies:
1st, because seat of the prior art is without memory mediation function, the driver of different driving habits is in weight It is new when driving vehicle, it is required to the driving habit according to oneself, the factor such as height readjusts the position of seat, the angle of backrest Degree etc., the operation to driver brings certain trouble, lacks convenience and comfortableness.
2nd, because seat of the prior art is without memory mediation function, different drivers are driving vehicle again When, it is necessary to readjust seat, but the angles and positions of adjustment are often difficult to accurate grasp, it is impossible to be rapidly reached optimum position, Expend regular hour and energy.
The content of the invention
The technical problems to be solved by the invention are, because seat of the prior art is without memory conciliation work( Can, the drivers of different driving habits is required to the driving habit according to oneself when driving vehicle again, the factor such as height, The position of seat, the angle of backrest etc. are readjusted, the operation to driver brings certain trouble, lack convenience and comfortable Property;When driver readjusts seat, the angles and positions of adjustment are often difficult to accurate grasp, it is impossible to be rapidly reached optimum bit Put, expend the technical problem such as regular hour and energy, and there is provided a kind of automotive seat and its automatic adjusting method.
The technical concept of the present invention is that, because seat of the prior art is without memory mediation function, difference is driven The driver for sailing custom readjusts the position of seat, the angle of backrest etc., the behaviour to driver when driving vehicle again Certain trouble is brought, lacks convenience and comfortableness;The angles and positions for adjusting seat simultaneously are often difficult to accurate grasp, Optimum position can not be rapidly reached, the technical problem such as regular hour and energy is expended, the invention provides one kind according to memory The mechanism of adjust automatically seat, including gravity sensing system and correction system, when different drivers drive vehicle again, pass through Gravity sensing system under Chain cushion, central control module is transmitted to by signal, and the central control module passes through school Positive system, whether first confirm that has data memory, if so, and in critical field, then correct system detectio seat whether with note Data are recalled consistent, if unanimously, without adjustment, if inconsistent, being automatically adjusted according to the last historical data.From And, the driver of the different driving habits effectively solved readjusts the position of seat when driving vehicle again, and not The technical problem of accurate location can be adjusted to rapidly.This technology is conceived brings facility to different drivers, greatly improves car Comfortableness.
Technical scheme provided by the present invention is a kind of automotive seat, including chair framework, fixed seat, horizontal slide rail, is leaned on The back of the body, cushion and headrest, the seat also include automatic adjustment system, the automatic adjustment system include gravity sensing system, in Control module and correction system are entreated, the gravity sensing system is arranged on below the cushion, described central control module one end It is connected with the gravity sensing system, the other end is connected with the correction system;The correction system is located at the chair framework Bottom, the correction system includes position sensor, adjustment motor, height adjusting screw and locking system.
