Description
Technical field
The present invention relates to automotive seating art field, more specifically to a kind of backrest and automotive seat.
Background technology
With the development in science and technology in vehicular traffic field, requirement more and more higher of the people for vehicle riding comfort.It is a kind of
The small of the back support technology of seat also arises at the historic moment, and is progressively applied to middle and high end passenger vehicle field.
In the past, such Seat lumbar support technology was usually using a kind of pneumatic support Form of Technique.Pneumatic support is to use
Air is passed through relevant control valve body by miniature air pump as power source, be blown into be placed in backrest foam pad rear portion shore gas
In utricule, by the inflation/deflation of pneumatophore, the local crowning or calm of backrest seat seat is realized, and then realize the waist to human body
Back-supported acts on.Such seat shores a simple application of air bag product, exactly shores air bag by one, is arranged in backrest
Wire netting trellis or tabular back support carry between structure support body and backrest foam pad.When shoring air bag by air-pump inflating, top
Support air bag is inflated and produces raised stroke, and then backrest foam pad is jacked up forward, and then make it that side occurs in face of chair
It is raised.
However, work as because the inside of some backrest sponge foaming pads has the backrest knot of posterior support framework types
Structure, its backrest sponge foaming pad the inside at rear, and there is the back of built-in metal or nonmetallic rack support to carry structure support body.Work as biography
When shoring air bag and being inflated raised of the waist support support meanss of system, will be by having built-in back to hold in the palm inside backrest sponge foaming pad
The barrier of structure support body is carried, and the effect of shoring is transmitted without normal direction seat direction, thus the air bag waist support support meanss of such seat
Arrangement will be difficult to implement.
Therefore, the problem of how avoiding the effect of shoring from being transmitted without normal direction seat direction, turns into those skilled in the art urgently
The technical problem of solution.
The content of the invention
It is an object of the invention to provide a kind of backrest and automotive seat, to avoid shoring effect without normal direction seat side
To the problem of transmission.
To achieve the above object, the present invention provides following technical scheme：
A kind of backrest, including：
Sponge foaming pad；
It is coated on the backrest seat of the sponge foaming pad side；
Integration foaming is integrated in inside the sponge foaming pad, and the support of the back away from the backrest seat side carries knot
Framework body；
The small of the back support meanss, the air bag waist support integration foaming of the small of the back support meanss are integrated in the sponge hair
Bubble pad is internal, and is arranged in the back support and carries structure-steel framing dignity to the side of affiliated backrest seat.
Preferably, in above-mentioned backrest, the air bag waist support includes shoring air bag and supporting back board；
The supporting back board asks load structure support body to be fixedly connected by fixture with the back；
The air bag of shoring is arranged in the side that the supporting back board holds in the palm load structure support body away from the back.
Preferably, in above-mentioned backrest, the fixture is wrapping-fixed belt, padlock or buckle.
Preferably, in above-mentioned backrest, it is described shore to be provided between air bag and the sponge foaming pad cover layer.
Preferably, in above-mentioned backrest, the layer that covers is engineering plastics sheet material, nylon plate, polyester sheet, fibre
Tie up the homogenous material plate or composite panel of the composition such as composite plate and stainless steel metal thin plate.
Preferably, in above-mentioned backrest, it is described cover layer for tissue layer, unwoven fabric, plastic sheeting, coating glue film or
Felt mat.
Preferably, in above-mentioned backrest, the edge for covering layer is carried out with the supporting back board by edge sealing thing
Periphery gluing is pasted, hook thorn hangs patch, the mode of tape edge locking carries out Seal treatment.
Preferably, in above-mentioned backrest, the air bag of shoring avoids moulding lacing wire inside the sponge foaming pad.
A kind of automotive seat, including Chain cushion and backrest, the backrest are the as above seat described in any one
Chair back.
It can be seen from the above technical scheme that backrest provided by the invention, opens when the small of the back support meanss and fills
When gas works, inside sponge foaming pad, support is loaded in the air bag waist support in front of the support load structure support body of back, is inflated expansion.Fill
The air bag waist support of gas expansion is shored forward so that sponge foaming pad it is just raised forward, backrest seat is jacked up, realized to seat
The small of the back support of the occupant of chair carries.When air bag waist support is lost heart, each utricule is deflated and tends to contract flat, sponge foaming pad and backrest
Seat gradually recovers to calm down state.
