In the foaming process of the foam structure body 74, as shown in fig. 13, two first soft inflatable bags 13 and two second soft inflatable bags 14 which are stacked up and down are fixed together in an adhesive manner and are arranged on the upper surface of the foam structure body 74; a flexible liner 77 is further arranged between the second soft air bag 14 and the seat surface sleeve 75, local bulge occurs around the height limiting structure 30, a tiny uneven state is generated, the flexible liner 77 can compensate the state, and the comfort flatness of the seat surface of the seat is improved;
or as shown in fig. 14, the two first soft inflatable bags 13 and the second soft inflatable bag 14 which are overlapped up and down are fixed together in an adhesive manner and are arranged on the lower surface of the foaming structure body 74;
Or as shown in fig. 15, the first soft air bag 13 and the second soft air bag 14 which are arranged in parallel are overlapped with the third soft air bag 15 and are positioned on the upper surface of the foaming structure body 74;
The arrangement of the air passage 11 of the superimposed soft air bag 10 can be alternatively made in the following two ways:
a as shown in fig. 14, each soft air bag 10 is independently provided with an air passage 11; the first soft air bag 13, the second soft air bag 14 and the third soft air bag 15 are respectively provided with an air passage 11 extending out of the foaming structure body 74; as can be seen from the enlarged view of the portion a of the figure, when the soft air bag is inflated, the periphery of the height limiting structure 30 will be in a locally inflated state, and the flexible pad 77 can just compensate for the locally inflated state, so that the comfort and flatness of the seat surface of the seat are improved.
B as shown in fig. 12 and 13, the joint of the first soft inflatable bag 13 and the second soft inflatable bag 14 is provided with an interconnection interface, so that the inflatable cavities of the first soft inflatable bag 13 and the second soft inflatable bag 14 are communicated; at this time, the first soft air bag 13 at the bottom is provided with an air passage 11 extending out of the foaming structure body 74;
2. The first and second soft air bags 13 and 14 are positioned side by side on the side adjacent to the seat cover 75 as shown in fig. 15; the third soft air bag 15 is located at a side away from the seat cover 75, preferably, as shown in fig. 15, since the third soft air bag 15 located at the bottom is in direct contact with the supporting frame 78 of the seat 70, in order to protect the third soft air bag 15, a flexible cushion 77 is further provided between the third soft air bag 15 and the supporting frame 78 as a protective layer.
Example six
In the fifth embodiment, the seat foaming structure is replaced by the seat foaming structure in the second embodiment, as shown in fig. 16, the upper surface of the foaming structure body 74 is provided with a first soft air bag 13 and a second soft air bag 14 side by side, and the lower surface of the foaming structure body 74 is provided with an air guiding structure 110; at this time, a heating pad 100 is further disposed between the foam mechanism body 74 and the seat cover 75, and the air guiding structure 110 of the seat can sequentially pass through the ventilation duct 74-1 of the foam mechanism body 74, the air guiding duct 12 of the first soft air bag 13 and the air guiding duct 12 of the second soft air bag 14, and then exit from the surface of the seat cover 75.
Therefore, the seat 70 provided in this embodiment integrates functions of heating, ventilation and hardness adjustment, and as shown in fig. 17, the backrest 71 of the seat 70 is provided with ventilation holes 70-1; the cushion 72 is provided with a heating pad 100; the functions are more abundant; the arrangement of the vent holes 70-1 may be increased as needed, and the base material of the heating mat is preferably a base material having good air permeability or is opened at the heating mat when there is ventilation, hardness adjustment and heating function. In a preferred embodiment, the heating, ventilation and hardness adjustment can be integrated on one control module for control adjustment, so that the cost is reduced.
Preferably, as shown in fig. 18, the hardness adjustment in the present embodiment may also be performed in a multi-layer adjustment manner. In the present embodiment, the upper surface of the foam structure body 74 is provided with the first soft air bag 13 and the second soft air bag 14 side by side, and the lower surface of the foam structure body 74 is provided with the third soft air bag 15 and the fourth soft air bag 16 side by side; at this time, a heating pad 100 is further disposed between the foam mechanism body 74 and the seat cover 75, and the air guiding structure 110 of the seat can sequentially pass through the air guiding holes 12 of the third and fourth soft air bags 15 and 74-1 of the foam mechanism body 74, and the air guiding holes 12 of the first and second soft air bags 13 and 14 and then exit from the surface of the seat cover 75.
The above description is only illustrative of the preferred embodiments of the present application and of the principles of the technology employed. It will be appreciated by persons skilled in the art that the scope of the application referred to in the present application is not limited to the specific combinations of the technical features described above, but also covers other technical features formed by any combination of the technical features described above or their equivalents without departing from the inventive concept. Such as the above-mentioned features and the technical features disclosed in the present application (but not limited to) having similar functions are replaced with each other.
