Height adjusting structure with directly communicating airbags

Abstract

A height adjusting structure with directly communicating airbags includes at least two airbags, where the airbags each receive and retain therein an elastic body. One of the airbags includes an air control unit connected thereto for controlling air filling and discharge of the airbags. The airbags are provided, in surfaces thereof that opposes each other, with corresponding passage holes and joint sections formed around circumferences of the passage holes. The joint sections are jointed so that the airbags are directly connected with no additional medium between the airbags and allowing the airbags to share the same air control unit to achieve flowability of air between the airbags, whereby advantages of efficient air filling and discharge of the airbags, being easy to manufacture, and reducing manufacture costs can be achieved.

I claim: 
     
         1 . A height adjusting structure with directly communicating airbags, characterized by comprising at least two airbags, the airbags each having an interior in which an elastic body is received, wherein one of airbags comprises an air control unit mounted thereto for controlling air filling and discharge of the airbags, the airbags comprising passage holes respectively formed in surfaces of the airbags that oppose each other and joint sections respectively formed around circumferences of the passage holes, the joint sections being jointed to each other, the airbags being directly connected to each other, the height adjusting structure with directly communicating airbags being received and retained in a mat.
