Description

The air pressure support system of seat

Technical field

The utility model relates to automotive seat, refers in particular to a kind of air pressure support system of automotive seat.

Background technology

The seat that vehicle was equipped with of general identical car money mostly is identical size and moulding, therefore identical car money is for meeting different heights, build passenger's the demand of taking, and how the seat design of front stall is become to have adjustable bed rearrangement chair front and back position and the function that can adjust chair back angle of inclination; Also because generally the seat of car front stall is in different positions, and under the state of chair back differing tilt angles, can be related to the space of taking of rear rider, and make the front stall seat of general car all have adjustable bed rearrangement chair front and back position mostly, and the function of adjusting chair back angle of inclination.

The adjustment front and back position that aforementioned relevant car front stall seat is possessed and the function at chair back inclination angle, still inadequate slightly with regard to steerman, because when steerman takes advantage of seat on the seat of operator's saddle, especially need possess good sight line, and the suitable supportive at position such as shoulder, waist, stern, leg, avoiding having influence on the ability of controlling, or, seat causes fatigue driving easily because taking uncomfortable to vehicle because taking discomfort, and then the safety of influence driving.

So that many depots further adjust the operator's saddle height of seat function, and lumbar support adjusts the standard that function is considered as its vehicle that dispatches from the factory and is equipped with, in the hope of can satisfy the user demand of steerman as far as possible; Again, similarly height of seat, lumbar support are adjusted function, are mostly to allow steerman seek comparatively suitable section between some set sections in manual or electronic mode; Yet some steerman feels therefore often to meet comparatively comfortable support state and seat can't be adjusted to the state that meets the steerman demand between two different sections.

Moreover, though being seen in the market automotive seat have possessed the function that can adjust the seat holding state, but still just can't allow the user adjust the soft or hard degree of seat voluntarily, with regard to its practicality and applicability, still there is the space that remains to be improved.

Summary of the invention

The specific embodiment

The air pressure support system of seat of the present utility model as shown in Figures 1 and 2, includes:

At least one group of airbag assembly 20, each airbag assembly 20 can be fixedly arranged on the positions such as waist, the shoulder back of the body, stern, thigh that seat 10 corresponds to the occupant respectively, each group airbag assembly 20 is made of airbag 21, air intake control valve 22 and gas exhausting valve 23, and its air intake control valve 22 and gas exhausting valve 23 also constitute the connection of signals with a control circuit 50;

One compression pumping 40 is located at the fixed position of seat 10 and is connect mutually with the air intake control valve 22 of each airbag assembly 20, so that airbag 21 is put on the air;

Aforesaid control circuit 50, can be equipped on the fixed position in seat 10 or space, car chamber, and constitute signals with the inlet and outlet control cock 22,23 of compression pumping 40 and each airbag assembly 20 and connect, in order to the running of control compression pumping 40, and the inlet and outlet action of controlling each airbag 21;

Above-mentioned member is when reality is used, its control circuit 50 is according to predefined pattern or control the advancing of airbag 21 of appointment via controlling in real time of user, the exhaust action, with each relevant airbag 21 in-to-in suction quantity and air pressure of accurate adjustment, make each relevant airbag 21 expanded support to desired degree, that is change relief state and the pliability that each airbag 21 corresponds to seat 10 seats, and then reach and adjust the purpose of seat 10 each position the human body supporting role, allow the occupant be able to sensation along with oneself, cushion height with seat 10, the relief degree of support at each position, and the soft durometer at each position is adjusted to only running condition.

In addition, air pressure of the present utility model supports the function that control system also can reach massage seat, be when using, the massage pressure that control circuit is switched to the pattern of massage functions and sets each airbag assembly, see through control circuit and control the inlet and outlet action of each airbag according to the setting pattern, the alternating state that makes each airbag continue to make expanded support, contraction changes, and can reach the effect that massage at position that the user is contacted.

As shown in Figure 3, the utility model in the specific implementation, the air intake control valve 22 of each airbag assembly 20 can be connect by first pipeline 24 and compression pumping 40, connect mutually with airbag 21 by another second pipeline 25, gas exhausting valve 23 then is located between second pipeline 25, and the inlet and outlet control cock 22,23 that will compress pumping 40, control circuit 50 and each airbag assembly 20 is integrated in the body 60, and be able to body 60 is arranged at the position of suitable placement, can not be subject to the restriction of seat 10 patterns.

Moreover, as Fig. 4 and shown in Figure 5, monolithic seat 10 can further be laid with ventilation conduit 70 in set zone, and is provided with a fan 80 and continues with ventilation conduit 70, in order to seat 10 air outside are sent into ventilation conduit 70, and discharge via the pore 12 on seat 10 top layers 11; When the top layer 11 of seat 10 is made of fabric construction, can be by the space between the fabric fibre as the pore 12 that allows air-flow discharge, when top layer 11 is when being made of natural or synthetic leather goods, can top layer 11 be formed allow the pore 12 of air-flow discharge by punching.

Because the hole of the pore 12 on seat 10 top layers 11 is less, so can allow this air-flow extend to each zone that seat 10 is laid with ventilation conduit 70 always, each zone that makes monolithic seat 10 be laid with ventilation conduit 70 all can produce fanning effect, it is except constituting heat radiation (or warming) purposes in the air-flow of ventilation conduit 70 top layer 11 to seat 10 via fleeing, also can form one to the occupant and brush effect, directly to allow passenger know the comfort that draft is produced through the air-flow of discharging via pore 12.

What deserves to be mentioned is, when the ventilation conduit of being laid when seat 10 70 is contained airbag 21 regional, can further between the top layer 11 of airbag 21 and ventilation conduit 70 and airbag 21 and seat 10, serve as a contrast and establish cage mesh liner 90, cage mesh liner 90 is made of elastic fibre, form the supporting role of whole body by elastic fibre, and be unlikely conquassation when taking, and pass through by the space air feed stream that elastic fibre is erected, so can allow air-flow walk around airbag 21 and discharge seat 10 by airbag 21 top positions smoothly, and be unlikely to influence the fanning effect of seat 10.

As mentioned above, the utility model provides seat one preferable feasible air pressure support system, and the whence proposes the application of utility model patent in accordance with the law; But, above implementation and graphic shown in, be one of the utility model preferred embodiment only, be not to limit to the utility model with this; Therefore, approximate with structure of the present utility model, device, feature etc. such as or identical mutually person all should belong within design goal of the present utility model and the claim.
