Abstract
A seat cushion for the production of a vehicle seat has a foam body and a carrier element. The carrier element is disposed on the back side of the foam body and provides mechanical support to the foam body on the back side thereof. At least one bubble element is disposed between the foam body and the carrier element and can be supplied with compressed air via an air inlet. The carrier element features an air-impermeable barrier layer on the side facing towards the foam body. The bubble element is composed of two bubble halves that are connected to one another by means of an airtight sealing joint, and wherein the bubble half facing away from the foam body is formed by a surface section of the barrier layer of the carrier element, and wherein the second bubble half facing towards the foam body is fastened at the assigned surface section of the barrier layer while forming the airtight sealing joint.
