In the present embodiment, as shown in fig. 5 and 6, the height limiting structure 30 includes a penetration height limiting belt 31 and/or a built-in height limiting belt 32 arranged in a distributed manner. The cross sections of the penetration type height-limiting belt 31 and the built-in type height-limiting belt 32 can be in various shapes such as a point shape, a strip shape, a circular shape or a honeycomb shape.

The longitudinal section of the penetrating height-limiting belt 31 is I-shaped, two ends of the penetrating height-limiting belt extend out of the soft inflatable bag 10, the vertical part of the penetrating height-limiting belt is slightly longer than the normal height of the soft inflatable bag 10 when the soft inflatable bag 10 is deflated, and when the soft inflatable bag 10 is inflated, the end part of the penetrating height-limiting belt extending out of the soft inflatable bag 10 can apply pressure to the surface of the soft inflatable bag 10 to avoid over-high expansion of a single point of the penetrating height-limiting belt;

in a preferred embodiment, the middle portions of the penetration height-limiting belt 31 and the built-in height-limiting belt 32 are opened for conducting gas on both sides of the penetration height-limiting belt 31 and the built-in height-limiting belt 32. The arrangement of the opening is beneficial to the circulation of the gas in the soft inflatable bag.

The penetrating height-limiting belt 31 and the built-in height-limiting belt 32 are made of flexible materials, and can be selected from nylon, polyester film, woven belts, woven cloth, non-woven cloth materials, soft plastic breathable films, plastic sheets with holes and the like.

In this embodiment, the gas source 50 may alternatively be any one of the following:

1. is provided by a micro air pump which is arranged separately;

2. supplied by compressed air in the body of the vehicle;

taking the seat cushion 72 of the car seat 70 as an example, the soft airbag is installed between the seat surface cover 75 and the foam structure 74 of the seat cushion 72, and the air passage of the soft airbag 10 extends from the bottom through the foam structure 74 and is connected with the air source.

In this embodiment, the air passages 11 of the soft airbags 70 disposed at various positions on the car seat 70 are respectively provided with the electromagnetic valve modules 40, and the control module 60 on the car seat 70 respectively and independently controls the inflation and deflation of the soft airbags 10 by controlling the on-off of the electromagnetic valve modules 40. The independent control of each soft air bag 10 enables the air inflation and air deflation of each soft air bag 10 to be carried out independently, so that each soft air bag 10 can form different air inflation and air deflation combinations, and the multifunctional adjustment and the adjustment of various hardness are realized.

Optionally, in other embodiments, all the soft airbags 10 on the car seat 70 are arranged in groups, and the air passages of each group of soft airbags 10 are merged on an air branch passage, on which a branch electromagnetic valve module is installed; the control module 60 controls the on-off of each set of branch electromagnetic valve modules to respectively control the inflation and deflation of each set of soft inflatable bags 10.

The grouping rule of the soft airbags 10 can be set according to the location area or the actual use requirement or control requirement, for example, when the soft airbags are grouped by area, the air paths of all the soft airbags located on the side wings 73 are arranged in parallel and connected with a common branch air path; the soft inflatable bags on all the seat cushions 72 are arranged in parallel and are connected with a common branch air passage; the soft inflatable bags on all the backrest 71 are arranged in parallel and are connected with a common branch air passage; the soft inflatable bags 10 arranged in groups can realize the master control, so that the soft inflatable bags in the same area synchronously act.

Taking the seat cushion 72 of the car seat 70 as an example, when the occupant 80 is seated on the seat with the soft airbag 10 installed, the height limiting structure 30 is bent and collapsed when the soft airbag 10 is in the unfilled state. The soft airbag 10 and the flexible filling inside thereof are compressed, the seat surface is in a relatively soft state, and the human trunk is sunk deeper into the seat surface as shown in fig. 7. When the soft airbag 10 is inflated while the occupant 80 is seated on the seat, the height-limiting structures 30 are relatively extended. The soft airbag 10 and the flexible filler 20 therein are compressed only a little and the seat surface is in a relatively hard state, and the torso of the human body is sunk into the seat surface to be shallow as shown in fig. 8.

Preferably, as shown in fig. 16, the hardness-softness adjustment in this embodiment may also be performed in a multi-layer adjustment manner. In this embodiment, it can be seen that, in order to match with a seat having a ventilation structure, a plurality of soft airbags 10 arranged at intervals in the same layer may also be adopted, and a ventilation duct 74-1 leading to the seat cover 75 is formed on the foam structure 74 between the soft airbags 10; a ventilation hole 74-1 is reserved between the first soft inflatable bag 13 and the second soft inflatable bag 14 which are arranged side by side at the upper part, and between the third soft inflatable bag 15 and the fourth soft inflatable bag 16 which are arranged side by side at the lower part; 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.

Preferably, as shown in fig. 18, the car seat in this embodiment may also be provided with a cover body preformed groove 79 above the soft airbag preformed groove 76 for placing the covering body 90.

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.
