Abstract

A vehicle subassembly includes at least one planar component. The at least one component has a material-specific deformability. To at least locally increase the deformability, through-holes are provided on at least one section of the at least one component. A method of producing of the component is also disclosed.

First claim

1 . A vehicle subassembly comprising:
at least one planar component having a material-specific deformability, wherein the at least on planer component defines a plurality of through-holes that at least locally increase the material-specific deformability of at least one section of the at least one component.

2 . The vehicle subassembly according to claim 1 , wherein the through-holes are slot-shaped, circular, dumbbell-shaped and/or Y-shaped.

3 . The vehicle subassembly according to claim 1 , wherein, on the at least one section, the through-holes are arranged periodically offset from each other.

4 . The vehicle subassembly according to claim 3 , wherein, on the at least one section, the through-holes form a regular pattern.

5 . The vehicle subassembly according to claim 1 , wherein the through-holes are incorporated into the at least one section in a cutting pattern.

6 . The vehicle subassembly according to claim 1 , wherein the least one planar component at least partially forms a seat component, a trim part, a hinge and/or a storage compartment of the vehicle subassembly.

7 . The vehicle subassembly according to claim 1 , wherein the at least one section with the through-holes has at least on bulge.

8 . The vehicle subassembly according to claim 7 , further comprising a guide body that receives an edge portion of the planar component such that the guide body deforms the planar component to form the at least one bulge wherein the guide body is shiftable along the at least one section to shift a location of the bulge.

9 . The vehicle subassembly according to claim 1 , wherein the at least one section with the through-holes forms a force-transmitting element on which a first and a second surface part of the component are integrally arranged, and which transmits forces resulting from utilization of the component from the first surface part to the second surface part.

10 . The vehicle subassembly according to claim 1 , wherein the at least one section with the through-holes forms a curve element on which a first and a second surface part of the component are integrally arranged obliquely to each other, wherein the curved element produces an elastic connection between the first surface part and the second surface part.

11 . A method of producing a planar component of a vehicle subassembly that has a material-specific deformability comprising:
forming through-holes though at least one section of the planar component to at least locally increase the deformability of the at least one section.

12 . The method according to claim 11 , wherein the through-holes are incorporated into the at least one section in a cutting pattern.

13 . The method according to claim 11 , wherein the planar component is one or more of a seat component, a trim part, a hinge, and a storage compartment of the vehicle subassembly.

14 . The method according to claim 11 further comprising forming a bulge in the at least one section.

15 . The method according to claim 11 further comprising inserting the planar component into a guide body to form a bulge in the at least one section.

16 . The method according to claim 11 , wherein the through-holes are slots.

17 . The method according to claim 11 , wherein the through-holes are arranged periodically offset from each other.

18 . The method according to claim 11 , wherein the through-holes form a regular pattern.

19 . The method according to claim 11 , wherein the at least one section with the through-holes forms a force-transmitting element on which a first and a second surface part of the component are integrally arranged, and which transmits at least one of actuating forces and load forces resulting from utilization of the component from the first surface part to the second surface part.

20 . The method according to claim 11 , wherein the at least one section with the through-holes forms a curve element on which a first and a second surface part of the component are integrally arranged obliquely to each other, wherein the curved element produces an elastic connection between the first surface part and the second surface part.
