Description

[0001] Illumination of an interior fitting or interior trim part in the interior of a motor vehicle as well as a drinking vessel holder and interior trim part. The invention relates to a drinking vessel holder with the features of the preamble of patent claim 1 and an interior trim part with the features of the preamble of patent claim 4.

[0002] A drinking vessel holder for a motor vehicle with the features of the preamble of patent claim 1 and an interior trim part with the features of the preamble of patent claim 4 are known from US 2010 / 0315826 A1. This document describes a drinking vessel holder with two pot-shaped receiving spaces. On the upper side of the drinking vessel holder, these receiving spaces are framed by a lighting device with an elongated light guide. This document also describes an interior trim part. It is also proposed to inject opaque elements into the cross-section of the light guide in certain areas.

[0003] DE 10 2009 017 296 A1 describes a cup holder in which a movable cam for securing a beverage container has an upper light-emitting surface. This surface is visible from above when the cup holder is empty. The light from a light source is guided via a light-guiding element from a light-entry surface to the light-exit surface.

[0004] JP 2015 229455 A also discloses a cup holder. This has a light source beneath its base. A light guide is arranged above the light source, which is itself covered by a light-tight cover. Light from the light source is coupled into the light guide from below and transmitted in the longitudinal direction of the light guide (radially outward). The transmitted light exits again as illumination light inside the cup holder via a radially circumferential light exit area between the cover and a side wall of the cup holder.

[0005] JP 2003 191782 A discloses a cup holder with a light source whose light is coupled into a ring-shaped light guide via a light coupling part. The light is transmitted longitudinally within the light guide and coupled out in a defined manner due to a reflective layer.

[0006] WO 2008 / 154378 A1 describes a door interior trim part with a door opener located in a frame. The door opener is designed as a light guide. Light from a light source is coupled in via a light coupling point, guided longitudinally through the door opener, and then coupled out again toward the frame due to an opaque and reflective layer covering the front of the door opener, which serves as an outcoupling structure.

[0007] JP 2014 043220 A discloses adjustable louvres of an air vent that can be illuminated by a light source. Each louvre 4 has a light-conducting component and a surrounding, opaque component. Towards the front, toward the outlet opening, the light-conducting component is covered with a decorative layer consisting of many individual layers. This layer allows light guided through the light-conducting component to pass through only certain semi-transparent areas.

[0008] WO 2012 / 056799 A1 discloses a lighting device for the interior of a motor vehicle. Specifically, a plurality of elongated light guides are arranged end-to-end and extend horizontally along the interior in a belt-like or linear fashion. Light-impermeable elements are arranged between the individual light guides. This is intended to ensure that only light can enter a light guide via a light coupling point assigned to that light guide.

[0009] Finally, WO 2012 / 132899 A1 describes a lighting device for the interior of a motor vehicle, which can be mounted in the interior paneling of the motor vehicle and can serve as interior lighting and reading light.

[0010] An inner area of ​​a flat light guide serves as a flat interior lighting system, into which light from light sources is coupled at the front and runs from the light coupling side to the opposite side. To prevent light from the light sources from reaching the outer areas of the light guide, grooves filled with reflective material are inserted into the light guide.

[0011] US 8 485 680 B2 discloses a drinking vessel holder with two pot-like receiving spaces. A flat, circumferential, translucent body is placed on the upper edge of the body. The translucent body has several flexible tabs that extend radially slightly into the receiving spaces and can provide support for a drinking vessel located therein. An elongated, circumferential light guide is attached to the translucent body, into which light from light-emitting diodes (LEDs) is coupled on two sides. At the top, i.e., toward the interior of a motor vehicle, the translucent body and the light guide are covered by an opaque cover. When illuminated, the light coupled into the light guide reaches the translucent body below and, via this, into the aforementioned flexible tabs, which extend into the receiving spaces.To prevent light from penetrating upwards from the flexible tabs into the interior of the vehicle, it is proposed, among other things, to provide the flexible tabs with an opaque coating on their upper side.

[0012] DE 10 2005 035 282 A1 describes a drinking vessel holder with a pot-shaped receiving space surrounded by an elongated light guide that runs around the outer wall of the receiving space. The light guide is also designed as a flexible spring ring and imparts a certain clamping force to holding jaws that project into the receiving space for holding drinking vessels. A light source located on the wall of the receiving space couples light into the light guide perpendicular to its left-hand extension and then couples it out again in the direction of the holding jaws. The document also describes a storage tray manufactured using a two-component injection molding process. In this tray, a bowl-like light guide and a similarly bowl-like cover that encloses the light guide on the outside are firmly bonded to one another.Below the light guide there is a light source whose light is coupled into the light guide and can exit through circumferential openings in the shell-like cover in the direction of its storage space.

[0013] WO 2014 / 058544 A1 also discloses an illuminable drinking vessel holder. This holder has two pot-shaped receiving spaces lined with an opaque inner lining. The inner lining has hemispherical protrusions pointing radially inward into the receiving spaces. The protrusions are flexible and serve to flexibly secure a drinking vessel. The wall forming the receiving spaces and the lining are manufactured using a multi-component injection molding process. Furthermore, light sources are arranged on the outer wall of the receiving spaces, emitting light toward the hemispherical protrusions. The hemispherical protrusions, in turn, have translucent elements through which the light from the light sources can penetrate into the receiving spaces.

[0014] Against the background of the prior art mentioned above, the object of the present invention is to provide a drinking vessel holder and an interior trim part for a motor vehicle, in which lighting is possible in an effective manner and with few components.

[0015] The above objects are achieved by a drinking vessel holder having the features of patent claim 1 and by an interior trim part having the features of patent claim 4. Advantageous embodiments or further developments of the invention can be found in the respective dependent claims.

[0016] At least one elongated light guide is arranged on the interior trim or interior panel part, and light beams from at least one illuminant are coupled into at least one light coupling point of the at least one light guide. The coupled light beams are coupled out again via at least one light coupling point.

[0017] For the purposes of the present invention, an elongated light guide is generally understood to be a light guide whose longitudinal extension is many times greater than its width or thickness. The elongated light guide can be straight, curved, or even circumferential. Its cross-section can also take on a variety of shapes, for example, round, oval, or square.

[0018] It is also a feature that the propagation of the coupled light rays in the longitudinal extension of the optical fiber is interrupted at at least one point on the optical fiber.

[0019] The light interruption at this point occurs at least in a part of the light guide cross-section which has a surface that is freely visible to a vehicle occupant.

[0020] This creates the basic prerequisites for effectively illuminating an interior fitting or trim part and, moreover, for achieving an appealing appearance of the lighting for a passenger.

[0021] It is further proposed that the interruption of the coupled light beams be caused by at least a second, opaque material component that is integrally bonded to the light guide. This process configuration allows for a very cost-effective implementation of the process with a small number of components. The integral bond is preferably achieved using a two- or multi-component injection molding process.

[0022] At least one point allows the coupled light beams to be partially transmitted along the length of the light guide. This allows for the flexible creation of a lighting appearance that is visible to vehicle occupants, and also allows the light beams, once coupled into the light guide, to be used at other points along the light guide.

[0023] As mentioned at the beginning, the invention is intended to provide a drinking vessel holder. With regard to the drinking vessel holder, the invention is based on such a drinking vessel holder, which has at least one pot-like receiving space, which is delimited by an upper border facing the interior of the motor vehicle when installed. At least one elongated light guide is mounted on the border. Furthermore, at least one light source is provided, the light rays of which can be coupled into the light guide and decoupled again perpendicular to its longitudinal extent.

[0024] The light guide has a light guide cross-section at least at one point in which the propagation of the coupled light rays along the length of the light guide is interrupted at least in some areas by at least one second, opaque material component. The opaque material component is integrally bonded to the light guide. The light is interrupted at this point at least in a portion of the light guide cross-section that includes a surface that is freely visible to a vehicle occupant.

[0025] This allows for pleasant lighting of the drinking vessel holder. The material components can preferably be joined together using a two- or multi-component injection molding process.

[0026] In order to be able to keep the required installation space for the light guide small despite a desired or required light interruption at one point, it is proposed according to the invention that, viewed in the longitudinal extension of the light guide, the surface formed by the opaque material component and a transparent surface of the light guide adjacent to it are flush with one another.

[0027] An alternative feature of the invention is that at one point on the light guide, the opaque material component extends over only a portion of the light guide's cross-section. This allows a portion of the light to continue to be guided in the longitudinal direction of the light guide despite an interruption in the light and to remain available and usable at another point.

[0028] Another development proposes that the drinking vessel holder have at least two pot-shaped receiving spaces, wherein the at least one second, opaque material component is inserted into the light guide between the at least two pot-shaped receiving spaces in a plan view of the drinking vessel holder in the assembled position. This is particularly advantageous if, without the light interruption between the pot-shaped receiving spaces—due to the component geometry or other influences—optical inhomogeneities in the light emission occur. This prevents such inhomogeneities from being locally visible, and an overall improved appearance can be achieved.

[0029] Furthermore, the present invention also relates to an interior trim part for a motor vehicle. Such an interior trim part can be, for example, an instrument panel, a headliner, a door side panel, or the like.

[0030] The invention is based on an interior trim part which has at least one elongate light guide and is equipped with at least one illuminant whose light can be coupled into the light guide and decoupled again perpendicular to its longitudinal extent.

[0031] The light guide has a light guide cross-section at at least one location, where the propagation of the coupled light along the length of the light guide is interrupted by at least one second, opaque material component. The opaque material component is integrally bonded to the light guide, preferably by means of a two- or multi-component injection molding process. The light is interrupted at this location at least in that portion of the light guide cross-section that includes a surface freely visible to a vehicle occupant. Furthermore, such an interior trim part can be used to achieve flexible and attractive illumination of the interior trim part.

[0032] In order to be able to keep the installation space requirements of the light guide low, it is proposed according to the invention that, viewed in the longitudinal extension of the light guide, the freely visible surface formed by the opaque material component and a transparent surface of the light guide adjacent to this are flush with one another.

[0033] In order to optimally utilize the coupled light of a light source, it is proposed that at least one location the opaque material component extends only over a part of the light guide cross-section.

[0034] In order to avoid the negative effect of a light accumulation (light spot) in the end region of the light guide caused by light reflection, it is also proposed in another embodiment of the invention that the at least one point of the opaque material component is arranged at such an end of the light guide which is opposite the at least one light source, wherein at that point the entire light guide cross-section is filled with the opaque material component.

[0035] Finally, the invention is also intended to protect a motor vehicle which has at least one drinking vessel holder according to the invention or at least one interior trim part according to the invention.

[0036] Preferred embodiments of the invention are illustrated in the figures and will be explained in more detail in the following description. This will also make further advantages of the invention clear. The same reference numerals, even in different figures, refer to the same, comparable, or functionally identical components. Corresponding or comparable properties and advantages are achieved, even if a repeated description or reference to them is not made. They show, schematically Fig. 1 a representation for the general explanation of the invention, Fig. 2 a representation according to section II from Fig. 1 , Fig. 3 a representation comparable to Fig. 1 to explain a further development of the invention, Fig. 4 a representation according to sectional view IV from Fig. 3, Fig. 5 a drinking vessel holder for a motor vehicle for implementing the invention in a plan view from above, Fig. 6 a side view according to view VI of Fig. 5 , Fig. 7 a sectional view according to section VII from Fig. 5 in two versions, Fig. 8 the representation of an interior trim part for implementing the invention, Fig. 9 a partial sectional view of the interior trim part according to sectional view IX from Fig. 8 in two embodiments and Fig. 10 a representation of the embedding of the light guide in the interior trim part in a view transverse to its longitudinal extent, in two embodiments.

[0037] First, the Figures 1 and 2Reference is made in more detail. These figures show a light guide 1 arranged in an interior trim part 2. The light guide 1 is designed as an elongated component with a longitudinal extension LE. Light beams L from illuminants 3 can be coupled into the light guide 1 via a plurality of light coupling points 12, of which only two are visible in the figure. The light guide 1 is formed by a transparent material component 10.

[0038] Furthermore, the light guide 1 has opaque material components 11 at several points S, which are distributed at equal intervals over the longitudinal extent LE of the light guide 1. Of the opaque material components 11 or points S, only one is visible in the figure. A portion of the coupled-in light rays L, namely light rays L1, is interrupted in its propagation in the longitudinal extent LE at the point S, while another portion of light rays L2 is coupled out at a light coupling point 13 approximately perpendicular to the longitudinal extent LE of the light guide 1 in the direction of an interior I of a motor vehicle (not shown in detail). The coupled-out light rays L2 can reach the interior I due to a clearance 20 introduced into the interior trim part 2.

[0039] The opaque material component 11 is embedded in the light guide 1 in such a way that the light interruption caused by it also occurs in a part of the light guide cross-section Q which has a surface O1 that is freely visible to a vehicle occupant F.

[0040] In the present exemplary embodiment, at point S, the entire cross-section Q of the light guide 1 is filled with the opaque material component and extends to an opposite surface O2 which is not freely visible when the light guide 1 is installed. The coupled-in light rays L are therefore completely prevented from propagating at point S and cannot propagate further in the longitudinal extent LE of the light guide 1. Therefore, in the exemplary embodiment, several light sources 3 and several light coupling points 12 are present along the length of the light guide 1. The light sources 3 shown in the present exemplary embodiment, as well as all light sources mentioned later, are preferably designed as light-emitting diodes (LEDs). The cross-section Q of the light guide 1 is circular in the present case, but the shape of the cross-section Q can also deviate from this shape and be polygonal, for example.

[0041] Based on the Figs. 3 and 4 In contrast to the previous figures, an elongated light guide 1' is shown in which, in contrast to the light guide 1, the opaque material component 11 extends only partially over the light guide cross-section Q at the points S. The light guide cross-section Q is thus divided into a first part Q1 with the opaque material component 11 and a second part Q2 with the transparent material component 10.

[0042] But also in this embodiment, the opaque material component 11 is introduced into the light guide 1' in such a way that at the points S, the light from the coupled-in light rays L (namely light rays L1) is interrupted at least in the part Q1 of the light guide cross-section Q, which in turn has the surface O1 of the light guide 1' that is freely visible to the vehicle occupant F.

[0043] The optical effect achievable for the vehicle occupant F is comparable to that of the first embodiment. They perceive the point S between the light output points 13 as a "blind spot," resulting in a visually appealing and interesting appearance.

[0044] The advantage of this embodiment is that light rays L are nevertheless not prevented from propagating in the longitudinal extension LE and are thus available elsewhere for use or light extraction without the need to provide additional illuminants 3 and light coupling points 12.

[0045] Now, based on the Fig. 5 to 7a method for illuminating an interior fitting in the form of a drinking vessel holder 4 is described. The drinking vessel holder 4 (also called a cup holder) has two pot-shaped receiving spaces 41, in each of which a drinking vessel 7 (indicated by dashed lines) can be placed. Radially movable retaining jaws 6, which extend inward into the pot-shaped receiving spaces 41 and are spring-loaded, allow placed drinking vessels 7 to be securely but removably clamped. The receiving spaces 41 are formed by a circumferential wall 40. An elongated, curved or elongated circumferential light guide 5 rests on top of the wall 40 (in the direction of an interior space I) and is suitably fastened to the wall 40.

[0046] As in the Fig. 5As can be seen, the light guide 5 replicates the course of the wall 40, wherein the light guide 5 consists of a transparent material component 50 which is interrupted at two points S1 and S2 by an opaque material component 51. It can also be seen that light beams L from lighting means 3 are coupled into the light guide 5 via two light coupling points 5a and 5c. The light beams L coupled into the light coupling point 5a are forwarded by the light guide 5 in the longitudinal extension LE, wherein their light propagation is interrupted by a light interruption 5b. The light interruption 5b is caused by the point S2. The light beams L coupled into the light coupling point 5c reach the longitudinal extension LE of the light guide 5 as far as a light interruption 5d, which in turn is caused by the point S1.The material components 50 and 51 are in turn preferably bonded to one another using a two-component injection molding process.

[0047] The light guide 5 is provided, at least over a large part of its longitudinal extent LE, with suitable light output structures (not shown in detail), which allow the coupled-in light rays L to be output perpendicular to the longitudinal extent LE of the light guide in the direction of the interior space I. Therefore, essentially two light exit regions LA1 and LA2 are formed, which, in a plan view of the drinking vessel holder 4, have a partially circular appearance and are separated from one another by the opaque regions S1 and S2. In other words, the regions S1 and S2 lie between the light exit regions LA1 and LA2, specifically where the wall 40 or the outline of the light guide 5 has corners 52, which leads to inhomogeneous light emission there. By arranging the locations S1 and S2 in these regions, an inhomogeneous light appearance can be elegantly avoided.

[0048] Out of Fig. 6It becomes clear that the freely visible surface O1 of the points S1 and S2 is flush with surfaces O3, which are each formed by the transparent material component 50 of the light guide 5.

[0049] In this way, despite the presence of several material components, a very flat design of the light guide 5 is possible, which offers great advantages in confined spaces.

[0050] In the Fig. 7a It can be seen that at points S1 and S2 the entire cross-section Q of the light guide 5 is filled by the opaque material component 51.

[0051] Based on the Fig. 7b, which represents an alternative embodiment 5' of a light guide, it can be seen that at the points S1 and S2 only a part Q1 of the light guide cross-section Q of the light guide 5' is filled with the opaque material component 51 and another part Q2 with the transparent material component 50. This in turn has the already Figs. 3 and 4 The advantage described is that, despite the partial light interruption at points S1 and S2, a portion of the coupled light beams L can propagate further along the longitudinal extent LE of the light guide 5'. When using the light guide 5', one of the two light sources 3 can therefore be omitted under certain circumstances.

[0052] The Figures 8 and 9now show a further exemplary embodiment of the invention using an interior trim part 8 in the interior of a motor vehicle K. The interior trim part 8 is an instrument panel of the motor vehicle K. An elongated light guide 9 with a transparent material component 90 is introduced into the interior trim part 8 perpendicular to the direction of travel or to the longitudinal direction of the motor vehicle K. The light guide 9 extends with its longitudinal extent LE between external outlets 80a, i.e. over a large part of the interior trim part 8. Via two light coupling points 9a on the end faces of the light guide 9, light beams L are coupled into the longitudinal extent LE of the light guide 9 via illuminants 3. The light guide 9 is arranged in the vertical direction approximately in the middle of the interior trim part 8 and optically divides it into an upper and a lower part.The light guide 9 is arranged above the outer vents 80a and also above the central vents 80b. Furthermore, it can be seen that the light guide 9 has a location S in the area above the central vents 80b, in which an opaque component 91 is incorporated into the light guide 9. In this way, a special appearance can be achieved in the illumination of the interior trim part 8. Furthermore, it can be seen that the previously described drinking vessel holder 4 is also installed in a center console of the motor vehicle K.

[0053] As can be seen from the Fig. 9a and 9b, which show two different designs of light guides 9 and 9', at point S the cross-section Q of the light guide 9 can be completely filled by the opaque material component 91 (light guide 9). It is also possible for the opaque material component 91 to fill only part Q1 of the cross-section Q of the light guide and for the other part Q2 to be filled by a transparent component 90 (light guide 9'). The material components 90 and 91 are preferably bonded to one another using a two-component injection molding process.

[0054] In both cases, the opaque component 91 is in a part of cross-section Q which has a surface O1 freely visible to a vehicle occupant F. The light guides 9, 9' are each embedded in an elongated channel 81 which runs along the interior trim part 8. Light rays L2 are indicated by dashed lines, showing that the coupled-in light rays L are coupled out of the light guides 9 and 9' approximately perpendicular to the longitudinal extent LE of the light guides 9 and 9', respectively.

[0055] Finally, based on the Figures 10a and 10b A view is shown showing the embedding of the light guides 9, 9' perpendicular to the longitudinal extent of the interior trim part 8. Its upper side facing the interior I is indicated only by dashed lines. Light decoupling points or light decoupling structures are also indicated by 92.

[0056] In both embodiments of the light guides 9, 9', they have a freely visible surface O1 at the location S1 where the opaque material component 91 is located. On both sides of the surface O1, the opaque material component 91 is bordered by freely visible surfaces O3, which are formed by the transparent component 90.

[0057] At the Fig. 10b Another special feature to be mentioned is that the light guide 9' is additionally provided at one end E2 with a point S2, into which the light guide 9' is completely filled with an opaque material component 91. This means that light rays which are coupled by the illuminant 3 at one end E1 and whose light propagation is not interrupted at the point S1 are passed on to the end E2 and there impinge on the opaque material component 91.

[0058] The opaque material component 91 prevents partial reflection of the light rays at the front end E2. This prevents the formation of an unwanted light spot there. List of reference symbols
