1. adjacently stacked, as shown in fig. 13, in the process of foaming and forming the foaming structure body 74, the two first soft airbags 13 and the second soft airbags 14 stacked up and down are fixed together by gluing and are arranged on the upper surface of the foaming structure body 74; a flexible gasket 77 is arranged between the second soft inflatable bag 14 and the seat surface sleeve 75, local tympanites are generated around the height limiting structure 30, a tiny uneven state is generated, and the flexible gasket 77 can make up the state, so that the comfortable flatness of the seat surface is improved;
or as shown in fig. 14, the two first soft airbags 13 and the second soft airbags 14 which are overlapped up and down are fixed together by gluing and are arranged on the lower surface of the foaming structure body 74;
or as shown in fig. 15, the first soft airbag 13 and the second soft airbag 14 which are arranged in parallel are arranged on the third soft airbag 15 in an overlapping manner and are positioned on the upper surface of the foaming structure body 74;
the air passage channel 11 of the overlapped soft airbag 10 is optionally arranged in the following two ways:
a as shown in fig. 14, each soft airbag 10 is independently provided with an air passage channel 11; the first soft inflatable bag 13, the second soft inflatable bag 14 and the third soft inflatable 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 part a in the figure, when the soft airbag is inflated, the periphery of the height limiting structure 30 can be locally inflated, and the flexible pad 77 can just compensate the state, so that the comfortable flatness of the seat surface is improved.
b as shown in fig. 12 and 13, the joint of the first soft airbag 13 and the second soft airbag 14 is provided with an interconnecting interface, so that the inflation cavities of the first soft airbag 13 and the second soft airbag 14 are communicated with each other; at this time, the first soft airbag 13 at the bottom is provided with an air passage 11 extending out of the foaming structure body 74;
2. the first soft airbag 13 and the second soft airbag 14 are arranged side by side and are positioned close to one side of the seat cover 75 at intervals and superposed as shown in fig. 15; the third soft airbag 15 is located at a side away from the seat cover 75, and preferably, as shown in fig. 15, since the third soft airbag 15 located at the bottom is in direct contact with the support frame 78 of the seat 70, in order to protect the third soft airbag 15, a flexible cushion 77 is further provided between the third soft airbag 15 and the support frame 78 as a protective layer.
EXAMPLE six
In this embodiment, on the basis of the fifth embodiment, the seat foaming structure is replaced with 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 the first soft airbag 13 and the second soft airbag 14 side by side, and the lower surface of the foaming structure body 74 is provided with the air guiding structure 110; at this time, the heating pad 100 is further disposed between the foaming 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 foaming mechanism body 74, the air guiding duct 12 of the first soft airbag 13 and the second soft airbag 14, and then exit from the surface of the seat cover 75.
Therefore, the seat 70 provided in this embodiment integrates the functions of heating, ventilation and hardness adjustment, as shown in fig. 17, the backrest 71 of the seat 70 is provided with the ventilation holes 70-1; the cushion 72 is provided with a heating pad 100; the functions are richer; the arrangement of the ventilation holes 70-1 can be increased according to the needs, and when the ventilation, hardness adjustment and heating functions are provided, the base material of the heating pad is preferably a base material with good air permeability, or the heating pad is opened. In a preferred embodiment, the heating, ventilation and hardness adjustment can be integrated on one control module for control and adjustment, so that the cost is reduced.
Preferably, as shown in fig. 18, the hardness-softness adjustment in this embodiment may also be implemented by a multi-layer adjustment manner. In this embodiment, the upper surface of the foaming structure body 74 is provided with the first soft airbag 13 and the second soft airbag 14 side by side, and the lower surface of the foaming structure body 74 is provided with the third soft airbag 15 and the fourth soft airbag 16 side by side; at this time, the heating pad 100 is further disposed between the foaming mechanism body 74 and the seat cover 75, and the air guiding structure 110 of the seat can sequentially pass through the air guiding duct 12 of the third soft airbag 15 and the fourth soft airbag, the ventilation duct 74-1 of the foaming mechanism body 74, the air guiding duct 12 of the first soft airbag 13 and the second soft airbag 14, and then exit from the surface of the seat cover 75.
The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed. It will be appreciated by a person skilled in the art that the scope of the invention as referred to in the present application is not limited to the embodiments with a specific combination of the above-mentioned features, but also covers other embodiments with any combination of the above-mentioned features or their equivalents without departing from the inventive concept. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
