<p>The height of an air-suspended vehicle seat can be adjusted solely by changing the internal pressure of the pneumatic spring. The technical problem to be solved is to achieve a blocking device (22) for the vertical oscillations of this type of vehicle seat which makes it possible to effectively lock the seat at any height. The solution proposed is a positioning element with a positioning device which is also used in combination with a non-return valve (26) for admission of compressed air into, and escape of compressed air from, the pneumatic spring.</p> |
