Trim part

A method for manufacturing a trim part for covering an airbag in a vehicle, the method comprising:

• providing a mould;
• forming a layer stack, comprising:
• placing at least one outer layer into the mould;
• placing at least one hinge layer comprising at least one first break line which forms a first part of a perimeter of a flap area on top of the at least one outer layer;
• and
• placing at least one structural layer on top of the at least one hinge layer;
• inserting the layer stack into a vacuum bag;
• connecting one or more resin tubes to the vacuum bag;
• inserting the vacuum bag into an autoclave machine;
• applying a predetermined pressure to the vacuum bag and heating the vacuum bag to a predetermined temperature;
• providing a vacuum inside the vacuum bag and enabling a flow of resin into the vacuum bag;
• and
• removing the trim part out of the vacuum bag;
• wherein at least one of the at least one outer layer comprises fiber composite material and the at least one structural layer comprises at least one second break line forming a breakthrough area corresponding to the flap area of the at least one hinge layer;
• wherein the at least one outer layer, the at least one hinge layer, and the at least one structural layer are bonded to each other in such a way that the trim part is a homogeneous part;
• wherein a second part of the perimeter of the flap area which is not formed by the at least one first break line is configured to serve as rotation axis for the flap area;
• wherein a first portion of the at least one second break line is aligned with the first part of the perimeter of the flap area formed by the at least one first break line, and a second portion of the at least one second break line is aligned with the second part of the perimeter of the flap area which is not formed by the at least one first break line.

A trim part for covering an airbag in a vehicle, the trim part comprising:

• at least one outer layer;
• at least one hinge layer forming at least a part of a flap area and being attached to a first surface of the at least one outer layer;
• at least one structural layer attached to a first surface of the at least one hinge layer facing away from the at least one outer layer;
• wherein at least one of the at least one outer layer comprises a fiber composite material;
• wherein the at least one structural layer comprises at least one break line forming a breakthrough area corresponding to the flap area of the at least one hinge layer;
• wherein the at least one outer layer is configured to be broken through by the flap area when a force is applied to the flap area, wherein the force is applied by an inflating airbag;
• wherein the at least one outer layer, the at least one hinge layer, and the at least one structural layer are bonded to each other in such a way that the trim part is a homogeneous part;
• wherein a contour of the breakthrough area is aligned with a contour of the flap area, such that the force applied by the inflating airbag is transferred to the flap area over the breakthrough area.
