Abstract: The pneumatic suspension apparatus 3 includes at least one pneumatic bag 4 for being attached with a vehicle between the vehicle frame and the vehicle seat for restricting the vehicle seat laterally and dampening vibrations; a regulator 6 pneumatically connected with the at least one pneumatic bag 4, where the regulator 6 adjusts the pressure in the at least one pneumatic bag 4; and a reservoir 8 pneumatically connected with the regulator 6. Optionally, a compressor 9 may be included to pressurize the reservoir 8. The compressor 9 may replace the reservoir 8 in supplying pressure to the pneumatic bag 4.
