Abstract

A seat module intended for a vehicle seat is designed as a seat cushion or backrest and can be actively ventilated. The seat module includes a cushion which has a lower foam layer impermeable to air, a central air-guiding layer made from a knitted fabric, and an air-permeable upper foam layer. The cushion is covered with a cushion cover and is divided by tacking into a face area and two side areas, which extend in the longitudinal direction. A cushion carrier accommodates the cushion. To improve the quality of the module for sitting comfort and long-term stability while achieving low manufacturing costs, the air-guiding layer rests on the lower foam layer in the face area of the cushion and directly on the cushion carrier in the side area of the cushion.
