An insert material is arranged between the non-woven layer and the fiber composite material, and has different compression properties than the fiber composite material. The fiber composite material forms together with the insert material and the non-woven layer a one-piece material composite. ## Claims ### Claim 1 A cushion element comprising a non-woven layer and a fiber composite material, wherein an insert material is arranged between the non-woven layer and the fiber composite material, the insert material having different compression properties relative to the fiber composite material, and the fiber composite material forming together with the insert material and the non-woven layer a one-piece material composite, and wherein a binding agent of the fiber composite material fixes the insert material and the non-woven layer via a curing process. ### Claim 2 (depends on 1) The cushion element as claimed in claim 1, wherein the insert material is a non-woven material or a pad. ### Claim 3 (depends on 2) The cushion element as claimed in claim 2, wherein the non-woven material or pad comprises natural fibers. ### Claim 4 (depends on 2) The cushion element as claimed in claim 2, wherein the non-woven material or pad comprises synthetic fibers. ### Claim 5 (depends on 1) The cushion element as claimed in claim 1, wherein the insert material extends only over a partial region of the surface of the cushion element. ### Claim 6 (depends on 1) The cushion element as claimed in claim 1, comprising at least two different insert materials including a first insert material and a second insert material arranged in different surface regions of the cushion element. ### Claim 7 (depends on 1) The cushion element as claimed in claim 1, wherein the insert material is more flexible than the fiber composite material. ### Claim 8 (depends on 1) The cushion element as claimed in claim 1, wherein the fiber composite material comprises fibers and the binding agent. ### Claim 9 (depends on 1) The cushion element as claimed in claim 1, wherein the insert material comprises a woven fabric or a spun non-woven fabric. ### Claim 10 (depends on 1) The cushion element as claimed in claim 1, wherein the insert material has a lower specific weight than the fiber composite material. ### Claim 11 (depends on 1) A headrest for a motor vehicle, comprising a cushion element as claimed in claim 1. ### Claim 12 (depends on 1) A vehicle seat for a motor vehicle, comprising a seat part and a backrest part, wherein the seat part and/or the backrest part comprises a cushion element as claimed in claim 1. ### Claim 13 (depends on 1) The cushion element as claimed in claim 1, wherein the cushion element is configured to form a vehicle seat cushion element. ### Claim 14 (depends on 1) The cushion element as claimed in claim 1, wherein the cushion element is configured to form a vehicle headrest cushion element. ### Claim 15 (depends on 1) The cushion element as claimed in claim 1, wherein the binding agent comprises latex. ### Claim 16 (depends on 15) The cushion element as claimed in claim 15, wherein the fibers comprise coir fibers. ### Claim 17 A cushion element comprising a non-woven layer and a fiber composite material, wherein a first insert material having a first hardness in a first direction and a second insert material having a second hardness in a second direction are arranged between the non-woven layer and the fiber composite material, the first direction is substantially perpendicular to the second direction, the second hardness is greater than the first hardness, the first and second hardnesses are different than a third hardness of the fiber composite material, and the fiber composite material forms together with the first and second insert materials and the non-woven layer a one-piece material composite, and wherein a binding agent of the fiber composite material fixes the first and second insert materials and the non-woven layer via a curing process; wherein the fiber composite material comprises fibers scattered throughout the binding agent via a distribution head guided by a robot.
