Abstract
A component for a transportation device includes a support structure, a cover portion, an elastic seal portion, which is formed between the support structure and the cover portion and which is integrally bonded to the support structure and/or to the cover portion, and an optical waveguide. The support structure, the cover portion and the seal portion delimit a receptacle, which is sealed by the seal portion and in which the optical waveguide is accommodated.
Claims12
A component for a transportation device, the component comprising:
- a support structure,
- a cover portion,
- an elastic sealing portion which is formed between the support structure and the cover portion and is connected in an integrally bonded manner to the support structure or to the cover portion, and
- an optical waveguide, wherein:
- the optical waveguide comprises one or more light guide fibers,
- the support structure, the cover portion and the sealing portion bound a receptacle which is sealed by the sealing portion and in which the optical waveguide is accommodated, and
- the sealing portion clamps the optical waveguide by pressing against the optical waveguide.
A method for producing a component for a transportation device, the method comprising:
- carrying out a two-component injection molding process comprising:
- performing a first injection by firstly injecting a first molding compound into a first cavity of a first injection mold such that one of the following parts of the component is formed:
- a support structure of the component or a cover portion of the component, and
- performing a second injection by secondly injecting a second molding compound into a second cavity of a second injection mold while the part formed by the first injection is arranged in the second cavity, so that an elastic sealing portion is cast on the part formed by the first injection;
- providing the other part of the component that is not formed by the first injection;
- and
- arranging the cover portion, the sealing portion and the support structure such that the cover portion, the sealing portion and the support structure form a receptacle which is sealed by the sealing portion and in which an optical waveguide is accommodated,
- wherein the optical waveguide comprises one or more light guide fibers, and
- wherein the sealing portion clamps the optical waveguide by pressing against the optical waveguide.
