Title:
車両シート用のエアサスペンション装置
Document Type and Number:
Japanese Patent JP7465566
Kind Code:
B2
Abstract:
The present invention provides a multifunctional air suspension device with a simplified device configuration and reduced air leakage. The air suspension device includes a reference height position maintenance mechanism that maintains an upper frame (13) at a reference height, and a reference height position modification mechanism. The reference height position maintenance mechanism is configured such that at the reference height, an arm member (72) acts on neither an air supply control cam (56) nor an air exhaust control cam (55), and when the height is lowered, the arm member (72) causes the air supply control cam (56) to rotate to open an air supply valve and raise the pressure of an air spring (18) so as to return to the reference height, whereas when the height is raised, the arm member (72) causes the air exhaust control cam (55) to rotate to open an air exhaust valve so as to return to the reference height. The reference height position modification mechanism sets a new reference height by pulling or sending out a wire member (68b) to rotate the arm member (72), thereby opening or closing the air supply valve or the air exhaust valve and causing the upper frame (13) to move up or down in response to a pressure change in the air spring (18).
