Automatic inflatable cushion

Abstract

An automatic inflatable cushion includes a cushion body, at least two airbags installed in the cushion body and capable of adjusting height and saturation independently, and an elastic member having fine pores filled in each airbag, and a manual switch valve installed on an outer surface of each airbag, so that when the manual switch valve is pressed towards the inside from both sides, the elastic member in the airbag is expanded and inflated naturally to improve the convenience of adjusting the height and saturation of the cushion.

1 . An automatic inflatable cushion, comprising:
 a cushion body;   at least two airbags, installed in the cushion and capable of adjusting the height and saturation;   an elastic member, having fine pores filled in the airbag; and   a manual switch valve, installed on a surface of the airbag, and including a valve body interconnecting the interior of the airbag to outside air, and two press buttons symmetrically installed on both side of the valve body and provided for selectively opening and shutting the valve body.   
     
     
         2 . The automatic inflatable cushion of  claim 1 , wherein the valve body includes a valve chamber formed therein and interconnected to the interior of the airbag, a valve port formed separately on both sides of the valve body and interconnected to the valve chamber, a valve door movably installed in the valve port, and spring installed between the valve doors and provided for driving the valve door to open or shut the valve port, and each press button is installed on the respective valve door and exposed from the respective valve body through the respective valve port, and provided for being pressed from both sides of the valve body towards the center of the valve body to open the valve port. 
     
     
         3 . The automatic inflatable cushion of  claim 2 , wherein the valve door includes an elastic airtight gasket installed thereon and abutting against the periphery of the valve port. 
     
     
         4 . The automatic inflatable cushion of  claim 2 , wherein the valve door has an end pivotally coupled to the valve body and the valve door is driven by the press button to swing to a tilted status to open the valve port. 
     
     
         5 . The automatic inflatable cushion of  claim 1 , wherein the cushion body has an opening formed on a surface of the cushion body and provided for exposing the manual switch valve. 
     
     
         6 . The automatic inflatable cushion of  claim 5 , wherein the opening has a ring sheathed on the manual switch valve. 
     
     
         7 . The automatic inflatable cushion of  claim 1 , wherein the valve body includes a flared ring disposed at the bottom of the valve body and capable of performing a high frequency wave sealing with the surface of the airbag surface. 
     
     
         8 . The automatic inflatable cushion of  claim 1 , wherein the two airbags are partially stacked, and the stacked position of the airbags has a smaller thickness. 
     
     
         9 . The automatic inflatable cushion of  claim 1 , wherein the cushion body has a first arc surface, and the airbag has a second arc surface corresponsive to the first arc surface. 
     
     
         10 . The automatic inflatable cushion of  claim 1 , wherein each manual switch valve is installed at a position opposite to an outer side of the cushion body or at a thickness-wise position opposite to a side of the cushion body.
