Abstract

PURPOSE:To maintain a constant air suspension pressure in response to the movement of an upper-and-lower position adjusting means by providing an air suspension and an upper-and-lower position adjusting means between a seat frame and a rail. CONSTITUTION:Upper brackets 3 and lower brackets 5 and provided under a seat 2. The first and second links 7a and 7b are pivoted to both brackets at one end of each link. The other end of each link is installed in slidable manner through the first and second rollers 10a and 10b. Both links are pivoted at a cross point 8. A compressed air is supplied to a suspension 6 from an air tank 11 through a valve 13 and air pipe 14. The second roller 10b is connected to the valve 13. The supply volume of compressed air is adjusted in response to the movement of both links so as to maintain a constant air pressure for the suspension.
