Abstract
A vehicle seat assembly comprises a seat bottom having a bottom cushion, a seat back coupled to the seat bottom with the seat back having a back cushion, and at least one of the bottom cushion and the back cushion having a passage. The assembly further includes a flow control layer coupled to the cushion having the passage with the flow control layer defining a first support area having a first plurality of slits and a second support area, adjacent to the first support area, having a second plurality of slits. Each slit defines a width that is moveable between a restricted position and a free-flowing position. The width of the first slits can move to the free-flowing position while the width of the second slits remains in the restricted position when the first support area receives a first load for flowing air through the first slits and the passage.
