PCT No. PCT/EP95/02538 Sec. 371 Date Mar. 18, 1998 Sec. 102(e) Date Mar. 18, 1998 PCT Filed Jun. 30, 1995 PCT Pub. No. WO97/02151 PCT Pub. Date Jan. 23, 1997In order to improve a vehicle driver's performance, a passenger compartment ventilation system is provided with an oxygen-enrichment unit (62) upon which fresh air acts via a compressor (24). A membrane (64) in the oxygen-enrichment unit (62) divides this flow of fresh air into a nitrogen-enriched partial flow which is discharged into the atmosphere and an oxygen-enriched partial flow which is discharged into the passenger compartment. Oxygen-enriched gas is preferably conveyed via a flexible discharge pipe (78) to the region near the driver's head.
