Abstract

Attachment part (1) for arrangement on a vehicle component (3), with - a carrier medium (20), - a covering material (5) that at least partially covers the carrier medium (20), and - a light guide (30) attached to the carrier means (20) by means of a fastening means (25), from which light can be coupled out, - wherein the carrier (20), the covering (5) and the light guide (30) are aligned to each other such that light coupled out of the light guide (30) exits through a light exit area (15), wherein - the fastening means (25) comprises a number of holding means (35) spaced apart from each other on the support means (20), each having a fastening section (40) operatively connected to the support means (20) and a receiving means (45) for receiving the light guide (30), wherein - the respective holding means (35) has two parallel flank sections (50) which extend in the longitudinal direction (L) of the light guide (30) forming a light emission section (60) operatively connected to the light emission area (15), characterized in that - the holding means (35) are attached to the support means (20), - wherein the optical fiber (30) is partially enclosed by the flank sections (50), - the flank sections (50) are connected to each other at their respective ends by a connecting section (55), - locking elements (62) are provided at the respective connection sections (50) with the light guide (30), and - the holding agent (35) is formed from polyoxymethylene or polypropylene, wherein - the fastening section (40) is received in congruent recesses (65) of the support means (20), and - a diffuser (10) is attached to the covering medium (5) forming the light exit area (15), which is adjacent to the light guide (30), wherein - the add-on part (1) is designed as a door panel. The present invention relates to an attachment for arrangement on a vehicle component according to claim 1 and to a motor vehicle equipped therewith according to claim 4. A light guide element for illuminating an area of a motor vehicle interior is known from this, wherein the light guide element is attached to a carrier means by means of a holder. From DE 10 2014 015 186 A1, an attachment for mounting on a vehicle component designed as a manhole cover is known, comprising a carrier element, a cover element that at least partially covers the carrier element, and a light guide attached to the carrier element by means of a fastening element, from which light can be coupled. The carrier element, the cover element, and the light guide are aligned with each other such that light coupled from the light guide exits through a light exit area. The fastening element known from the aforementioned prior art is designed as a groove in which the light guide is positively engaged. In practice, however, such an arrangement has the disadvantage of noise generation and sometimes uneven light output.

Description

The present invention relates to an attachment for arrangement on a vehicle component according to claim 1 and to a motor vehicle equipped therewith according to claim 4. From the WO 2012/ 022 791 A1 A light guiding element for illuminating an area of a motor vehicle interior is known, wherein the light guiding element is attached to a support means by means of a holder. From the DE 10 2014 015 186 A1 A component for attachment to a vehicle component designed as a manhole cover is known, comprising a carrier, a cover at least partially covering the carrier, and a light guide attached to the carrier by means of a fastening element, from which light can be extracted. The carrier, the cover, and the light guide are aligned with each other such that light extracted from the light guide exits through a light exit area. The fastening element known from the aforementioned prior art is designed as a groove in which the light guide is positively engaged. In practice, however, such an arrangement has the disadvantage of noise generation and sometimes uneven light extraction. From the EP 2 287 042 A1 is an add-on component known as part of indirect vehicle interior lighting, with - a carrier medium, - a covering agent that at least partially covers the carrier medium, and - a light guide attached to the carrier medium by means of a fastening device, from which light can be coupled out, - wherein the carrier, the covering material and the light guide are aligned to each other in such a way that light coupled out of the light guide exits through a light exit area, wherein - the fastening means comprises a number of holding means spaced apart from each other on the support means, each having a fastening section operatively connected to the support means and a receiving means for the light guide, wherein - the respective holding element has two flank sections parallel to each other, which extend in the longitudinal direction of the light guide, forming a light exit section operatively connected with the light exit area. Here too, it cannot be ruled out that in practice the disadvantages of noise generation and sometimes uneven light emission may arise. The object of the present invention is to overcome this disadvantage. This problem is solved by an attachment according to claim 1. Specifically, this task is solved by an attachment for mounting on a vehicle component, with - a carrier medium, - a covering agent that at least partially covers the carrier medium, and - a light guide attached to the carrier medium by means of a fastening device, from which light can be coupled out, wherein the carrier medium, the covering medium and the light guide are aligned to each other in such a way that light coupled out of the light guide exits through a light exit area, wherein the fastening means comprises a number of holding means spaced apart from each other on the support means, each having a fastening section operatively connected to the support means and a receiving means for the light guide, wherein - the respective holding element has two flank sections parallel to each other, which extend in the longitudinal direction of the light guide, forming a light exit section operatively connected with the light exit area. The attachment according to the invention is characterized by the fact that - the holding means are attached to the carrier, - wherein the optical fiber (30) is partially enclosed by the flank sections (50), - the flank sections are connected to each other at their respective ends by a connecting section, - locking elements are provided at the respective connection sections with the light guide, and - the holding agent is formed from polyoxymethylene or polypropylene, wherein - the fastening section is included in congruent recordings of the support means, and - a diffuser is attached to the covering material, forming the light exit area, which is adjacent to the light guide, wherein - the add-on part is designed as a door panel. This provides a simple and cost-effective means of integrating the light guide into a door panel, which is securely held in discreet locations without resulting in noise or uneven light emission in practice. A particularly simple construction and secure mounting of the light guide is achieved when the mounting device has two parallel flank sections that extend in the longitudinal direction of the light guide, forming a light-exit section operatively connected to the light-exit area, and are connected to each other at their respective ends by a connecting section. According to a preferred embodiment, the retaining means partially surrounds the light guide; this further simplifies the retention of the light guide. According to a further preferred embodiment, the light guide is held in the holding element by frictional and/or form-fitting means. This further simplifies the holding of the light guide. Noise formation is reliably avoided because, according to the invention, the holding agent is
