ABSTRACT:
A method and a system for quantitative determination of the seat climate of a seat cushion is provided. For this purpose, the seat surface is subjected, during realistic mechanical loading of the seat cushion to be tested, to a flow of moisture from a climate mat. Any moisture stagnation at the seat surface is measured. For this purpose, the seat cushion, covered with a flexible multilayer climate mat, is loaded realistically via an anthropomorphically shaped seat testing punch. The climate mat consists of the following layers: a plurality of flat moisture sensors; a trouser material layer with low moisture uptake; a distribution layer that is readily permeable to air and has a noncompressible structure; a fleece layer that can be moistened and replaced as the moisture storage medium; an electrically insulating vapor barrier; and an electrically heatable heating mat that can be set to a specific temperature.
