Abstract

A seat module is designed as a seat cushion or backrest and can be actively ventilated. The seat module includes a cushion, which has a cushion pad impermeable to air and an upholstered zone that extends over the latter and through which air can be made to flow and which is covered by an air-permeable cushion cover. A cushion carrier accommodates the cushion. To improve the quality of the module as regards sitting comfort and long-term stability combined with low manufacturing costs, the upholstered zone through which air can be made to flow is composed of three layers and in the manner of a sandwich of two rubberized hair layers and a knitted layer of coarse-mesh knitted spacing fabric in between the hair layers.
