Compared with the prior art, the beneficial effects of the utility model are that:
1. in the air bag inflation process, under the restraint effect of the height limiting structure, the air bag expands around, the expansion force extrudes the flexible material from the horizontal direction, the material in the unit section of the flexible material becomes more, the hardness of the flexible material is increased, and the hardness of the cushion is increased. 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 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 with the air pump 6, under the height restriction of the height limiting structure 2a, the air bag 2 can only expand around, the expansion force squeezes the flexible material 3 from the horizontal direction, and the material in the unit cross 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 cross 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 gas pouch 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 a 3 or 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.
