at least one support layer which is weakened along an opening line which delimits an opening cover; and
a decorative layer arranged over the support layer and which has a local weakening in a region of a tear line, the decorative layer having a thickness of at least 0.8 mm in the region of the tear line,
wherein the tear line has a first lateral linear portion and extends in a zigzag pattern into a second lateral linear portion, said tear line at an angle to a direction perpendicularly with respect to the plane of a surface of the trim part.
2. The trim part of claim 1 , wherein the decorative layer is composed of leather.
3. The trim part of claim 1 , further comprising an intermediate layer which is arranged over the support layer.
4. The trim part of claim 3 , wherein the decorative layer is arranged over the intermediate layer.
5. The trim part of claim 3 , wherein the intermediate layer is adhesively bonded over its full area to the support layer.
6. The trim part of claim 1 , wherein the tear line follows a curve at least in sections, the curve having an amplitude at least perpendicularly with respect to an imaginary tear line.
7. The trim part of claim 1 , wherein the tear line, at least partially, comprises a plurality of weakened points which are connected to one another.
8. The trim part of claim 1 , wherein the tear line, at least partially, comprises a plurality of weakened points which in each case lie at peaks of the zigzag pattern.
9. The trim part of claim 1 , wherein the decorative layer is composed of a single piece of leather.
10. The trim part of claim 1 , wherein the decorative layer has the same thickness over the entire area of the support layer.
11. A trim part for covering a motor vehicle airbag, the trim part comprising:
a support which is weakened along an opening line which delimits an opening cover;
an intermediate layer arranged over the support layer;
an adhesive layer which fastens the intermediate layer to the support; and
a decorative layer arranged over the support layer and which has a local weakening in a region of a tear line, the decorative layer having a thickness of at least 0.8 mm in the region of the tear line, wherein the tear line has a first lateral linear portion and extends in a zigzag pattern into a second lateral linear portion, said tear line at an angle to a direction perpendicularly with respect to the plane of a surface of the trim part.
