Description
Technical field
The invention belongs to automotive seating art fields, and in particular to a kind of pair of adjusting driver seats and its backrest profile are comfortable
Spend emulation mode.
Background technology
Automotive seat is the tie for connecting driver and vehicle body, is most typically, contacts most frequent man-machine interface point with people,
It must satisfy intention requirement when consumer purchases vehicle.Automotive seat is responsible for support sitting posture, fixed driver, vibration damping in the car
Deng it is consumer's individual, seat itself design, three kinds of sitting posture that it is not outer, which to influence the most important factor of its comfort,.Unreasonable
Seat system design not only allows driver to feel uncomfortable, but also is easy to generate fatigue, and causes the lesion of body.Study table
The pressure distribution of bright man-machine interface is to influence the key factor of comfort.Due to partes corporis humani position to the ability to bear of pressure not
Together, hypertonia or too low all occupant can be made to feel uncomfortable.Whether the reasonability of automotive seat design, people is directly affected
Whether the optimization of machine interface succeeds.
Though the design of the intrinsic elasticity profile before existing motor vehicle seat back by face has contemplated that human body true form, but still
For fixed form, the small of the back true form of different drivers can not be matched, driving fatigue is caused.Many drivers can only use
Waist pillow is to lean on face before padded backrest, in the hope of building more comfortable driving environment.
The intrinsic elasticity curved profile in face is leaned on before the backrest of double adjusting driver seats of hommization, it is also desirable to be set
Meter.Therefore the means by emulating are needed, is distributed by human body back pressure, seat comfort is instructed to design.
