Cushion for a vehicle seat

A cushion for a vehicle seat, comprising:

• a cushion core made of a foam material,
• an air-permeable and moisture-permeable covering layer by which the cushion core is lined, and
• a network formed in the cushion core, the network comprising grooves spaced apart from one another, which are open toward the covering layer, and through which air is forced, and channels which pass through an entire core thickness of the cushion core and which, at one end, open into grooves and, at the other end, open out freely on an outer face of the cushion core directed away from said grooves,
• wherein the grooves are intersecting longitudinal grooves and transverse grooves having intersection areas at which the channels open out,
• wherein at least one shaft is provided in the cushion core, passes completely through the core thickness of the cushion core, opens out in at least one of the longitudinal grooves, the transverse grooves, or both the longitudinal and the transverse grooves, and is open on the outer face of the cushion core directed away from the longitudinal and transverse grooves, and
• wherein a miniature fan, which sucks air in from an area surrounding the cushion, is arranged in the at least one shaft.
