and in the air bag inflation process, the height limiting structure is used for forcing the circumferential direction of the air bag to expand outwards so as to horizontally extrude the flexible material.
Preferably, the air bag further comprises a foam body positioned on the upper side of the air bag, and the flexible material is integrally formed on the lower side of the foam body.
Preferably, the air bag is constructed in a rectangular structure.
Preferably, the height limiting structure is located inside the air bag, and the upper end and the lower end of the height limiting structure are respectively connected with the upper part and the lower part of the air bag.
Preferably, the height limiting structure is sheet-shaped, and a through hole is formed in the middle of the height limiting structure.
Preferably, an air supply pipeline is arranged on the lower side of the support plate, and the air supply pipeline penetrates through the support plate to be communicated with the interior of the air bag.
The second object of the present invention is to provide a car seat, which is characterized in that: the automobile seat comprises the cushion capable of realizing hardness adjustment.
Preferably, the seat is provided with an air pump for inflating and deflating the air bag.
The invention also aims to provide a cushion hardness adjusting method, wherein the cushion comprises a flexible material, and the hardness increasing method of the flexible material comprises the following steps: applying extrusion force to the flexible material from the horizontal direction to increase the material proportion in the unit section of the flexible material; the method for reducing the hardness of the flexible material comprises the following steps: and reducing the extrusion force applied to the flexible material so as to reduce the material proportion in the unit section of the flexible material.
Preferably, the pressing force is provided by an inflation deformation of the airbag.
Compared with the prior art, the invention has the beneficial effects that:
1. in the air bag inflation process, under the restraint effect of limit for height structure, the air bag is to expanding all around, and this expansive force extrudees flexible material from the horizontal direction, and the material in flexible material unit cross-section becomes more for the hardness grow of flexible material, thereby realize the cushion hardness increase. On the contrary, in the air bag deflation process, the horizontal extrusion force is reduced, the material in the unit section of the flexible material is reduced, and the hardness of the flexible material is reduced, so that the softness of the cushion is increased.
2. The mode realizes that soft or hard adjusts more than adopting, no matter is at static support in-process, still in the adjustment process, and user's buttock lasts and has better comfort level, does not have diaphragmatic sense.
Drawings
Fig. 1 and 2 are sectional views of a seat cushion, in which the air bags 2 in fig. 1 are inflated more than the air bags 2 in fig. 2;
fig. 3 is a schematic view of the structure of the car seat (the foam body 4 of the seat cushion is hidden).
Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
Example one
As shown in fig. 3, an automobile seat a has a seat cushion, the seat cushion includes a support plate 1 fixed in a seat frame 7, six air bags 2 are distributed on the upper side of the support plate 1 in an array manner, a space is provided between any two adjacent air bags 2, as can be seen from fig. 1 and 2, the space is filled with a flexible material 3, a height limiting structure 2a is arranged inside the air bags 2, and in the process of inflating the air bags 2, the height limiting structure 2a keeps the air bags 2 at a stable height.
An air supply pipeline 5 is arranged on the lower side of the supporting plate 1, the air supply pipeline 5 penetrates through the supporting plate 1 to be communicated with the air bag 2, an air pump 6 is installed on the seat, and the air pump 6 can charge and discharge air to the air bag 2 through the air supply pipeline 5. Referring to fig. 1, in the process of inflating the air bag 2 by the air pump 6, under the height constraint action of the height limiting structure 2a, the air bag 2 can only expand to the periphery, the expansion force extrudes the flexible material 3 from the horizontal direction, and the material in the unit section of the flexible material 3 is increased, so that the hardness of the flexible material 3 is increased. On the contrary, referring to fig. 2, during the deflation of the air bag 2, the horizontal squeezing force is reduced, and the material in the unit section of the flexible material 3 is reduced, so that the hardness of the flexible material 3 is reduced. Therefore, the softness and hardness of the cushion can be adjusted by inflating and deflating the air bag 2.
The upper side of the air bag 2 is provided with a foam body 4, the foam body 4 is the flexible supporting foam of the seat, in the embodiment, the flexible material 3 between the air bag 2 and the foam body 4 are integrally formed, the materials of the flexible material and the foam body are the same, and the flexible material and the foam body can elastically deform under the action of pressure. In the process of adjusting the hardness, the height limiting structure 2a can keep the six air bags 2 at the same height, so that the cushion has better flatness and excellent comfort.
As shown in fig. 3, the air bag 2 has a rectangular structure, and the horizontal section of the air bag is square, so that the deformation of the periphery of the air bag 2 is uniform, and the supporting hardness of each area of the seat cushion is consistent. In the present embodiment, the airbag 2 is made of a deformable elastic material, namely: during inflation of the interior of the airbag 2, the airbag 2 can expand, thereby providing a pressing force. Further, the air bag 2 is a TPU high-frequency welding air bag or a blow molding air bag or 3 or a soft rubber air bag.
Referring to fig. 1, in the present embodiment, the height limiting structure 2a is a spacer disposed inside the airbag 2, and the upper and lower ends of the spacer are connected to the upper and lower portions of the airbag 2, respectively. The barrier sheet is vertically arranged, the air bag 2 is partitioned from the left chamber and the right chamber, and in order to ensure that the left chamber and the right chamber of the air bag 2 can be inflated simultaneously, the middle part of the barrier sheet is provided with a through hole 2b.
To further enhance seat comfort, a ventilation strip may also be disposed within the foam body 4.
Example two
A cushion hardness adjusting method comprises a flexible material 3, and the hardness increasing method of the flexible material 3 comprises the following steps: the extrusion force is applied to the flexible material 3 from the horizontal direction to shrink the flexible material 3, and the material proportion in the unit section of the flexible material 3 can be increased in the process, so that the hardness of the flexible material 3 is improved. The method for reducing the hardness of the flexible material 3 comprises the following steps: the extrusion force applied to the flexible material 3 is reduced, so that the flexible material 3 is self-deformed and expanded, the material proportion in the unit section of the flexible material 3 can be reduced in the process, and the hardness of the flexible material 3 is reduced. In the present embodiment, the pressing force can be applied by inflating the airbag 2, or can be applied by other mechanical transmission means.
