Vehicle seat
First Claim
1. A vehicle seat having a back rest and support surface for supporting the vehicle user, in which at least one portion of the support surface facing the seat user forms at least the outside of a wall, the inner side of which wall borders at least one channel, through which air flows, wherein said wall is at least substantially impermeable to air at the pressure prevailing in the channel, and said wall comprises a material which, when there is a drop in the water vapor partial pressure from the outside to the air flowing through the channel, transfers water vapor in the direction of this partial pressure drop.

Abstract
A vehicle seat has a back rest and support surface for supporting the vehicle user, in which at least one portion of the support surface facing the seat user forms at least the outside of a wall, the inner side of which wall borders at least one channel through which air flows. The wall is at least substantially impermeable to air at the pressure prevailing in the channel and comprises a material which, when there is a drop in the water vapor partial pressure from the outside to the air flowing through the channel, transfers water vapor in the direction of this partial pressure drop.
