<p>Self-supported cushion assembly for an interior vehicle part comprising: a main frame (4), a rigid plate (3) supported on the main frame (4), a tridimensional fabric (2) supported on the rigid plate (3), wherein the tridimensional fabric (2) comprising a back knitted layer (2.2) lying on the rigid plate (3), a shaping knitted layer (2.1), a core layer (2.3) having spacer yarns (2.3.2) which connect the back knitted layer (2.2) with the shaping knitted layer (2.1) in such a way that all of them (2.1, 2.2, 2.3) are knitted all together as a sole element wherein the tridimensional fabric (2) comprises two different cushion areas (6) defined and delimited by a correspondent change area (7) adjacent to both of them (6) where the thickness of said change area (7) is lower than the thicknesses of such two different cushion areas (6), the tridimensional fabric (2) has first attaching means (8) in order to attach the tridimensional fabric (2) to the main frame (4) and /or to the rigid plate (3), the shaping knitted layer (2.1) is tightened to constrain the core layer (2.3) against the rigid plate (3) giving in this way the external shape to the self-supported cushion assembly (1), an edge (2.1.1) of the shaping knitted layer (2.1) being peripherally attached to the main frame (4) and/or to the rigid plate (3) by means of first attaching means wrapping a peripheral edge (3.1) of the rigid plate (3), the back knitted layer (2.2) having second attaching means (9) in order to attach the back knitted layer (2.2) with the rigid plate (3).</p> |
