Description

[0001] The invention relates to a load carrier arrangement for a motor vehicle according to the preamble of claim 1.

[0002] Such a load carrier arrangement is known from US 2016 / 0 362 055 A1. Such a load carrier arrangement for a motor vehicle is also known from WO 2014 / 022 435 A1, US 2016 / 0 280 114 A1, and AU 2006100386 A4.

[0003] Another load carrier assembly is known from EP 3 192 702 B1. The known load carrier assembly comprises an extruded aluminum profile, which is provided with an undercut receiving groove on its upper side, which is open to the outside through a longitudinal slot extending over the entire length of the light metal profile. To conceal this longitudinal slot, a slot cover is provided, which comprises a cover strip ( Fig. 8 and Fig. 9) and support sections formed integrally with the cover strip, which extend from the cover strip into the receiving groove and are supported in the region of a base of the receiving groove. The support sections are designed to be elastically flexible, so that when a fastening element is inserted into the longitudinal slot from the outside, the slot cover is pushed back into the interior of the receiving groove. After the fastening element is removed from the longitudinal slot, the slot cover automatically returns to its original position, in which the cover strip closes the longitudinal slot flush.

[0004] EP 3 470 271 B1 discloses a further load carrier profile with a slot cover for a longitudinal slot of a receiving groove, in which support sections carrying the cover strip are provided with defined material weakenings which enable a defined buckling of the support sections when a load acts on the cover strip from the outside.

[0005] The object of the invention is to provide a load carrier arrangement of the type mentioned above which ensures a particularly reliable and durable covering or release of the longitudinal slot of the receiving groove of the load carrier profile.

[0006] This object is achieved by the features of claim 1. The elastomer hollow profile extends within the receiving groove in the longitudinal direction of the load carrier profile, relative to a state of the elastomer hollow profile inserted into the load carrier profile. The elastomer hollow profile is preferably a rubber hollow profile. The closed design of the elastomer hollow profile with a circumferential wall continuous over the entire circumference of the elastomer hollow profile enables uniform dimensional stability even over a longer period of use. The elastomer hollow profile can extend over the entire length of the load carrier profile. Preferably, several mutually identical elastomer hollow profiles are provided, which can be positioned one after the other in the load carrier profile in the longitudinal direction of the receiving groove and thus in the longitudinal direction of the load carrier profile.Each elastomer hollow profile has a cover strip that is essentially flush with the longitudinal slot of the receiving groove, as well as side flanks and a support base, which each merge integrally into one another. The support base supports the elastomer hollow profile on a base of the receiving groove. The design of the slot cover as an elastomer hollow profile enables particularly reliable and consistent support within the receiving groove of the load carrier profile. The elastomer hollow profile is preferably provided with a single hollow chamber, so that the elastomer hollow profile is designed like a hose with a cross-section adapted to the cross-section of the receiving groove. Alternatively, it is possible to provide several separate hollow chambers in the elastomer hollow profile. In the case of a load carrier arrangement mounted on a vehicle roof, the access side refers to an upper side.If a load carrier arrangement is mounted on the rear of a motor vehicle so that a corresponding load carrier profile protrudes rearward with its open side, i.e. the open receiving groove, the access side is correspondingly oriented rearward. According to the invention, the elastomer hollow profile - viewed in a functional position positioned in the receiving groove - has a support base on the bottom side and a cover section on the access side, wherein the support base is supported on the bottom of the receiving groove, and wherein the cover section is dimensioned such that the cover section ends flush with the longitudinal slot in the unloaded functional position, and that the cover section merges into the support base via side flanks of the wall casing of the hollow profile. The access-side cover section, the side flanks and the support base merge into one another as a continuous outer wall of the elastomer hollow profile, resulting in a circumferential wall casing.

[0007] According to the invention, the support base has a downwardly open, groove-like support region on the underside, which, when positioned in the functional position in the receiving groove, engages around a hump-shaped profile section of the load carrier profile. The terms "underside" and "open downwards" refer to an alignment of the load carrier profile and the elastomer hollow profile within the receiving groove of the load carrier profile such that the longitudinal slot of the receiving groove is directed upwards. Accordingly, the hump-shaped profile section is provided opposite at the bottom of the receiving groove. The support region of the support base of the elastomer hollow profile engages around the hump-shaped profile section of the load carrier profile in a form-fitting manner, wherein the elastomer hollow profile is inserted into the receiving groove in particular from one end face of the load carrier profile.

[0008] In one embodiment of the invention, the elastomer hollow profile has a single hollow chamber, and a wall casing surrounding the hollow chamber is designed to be elastically deformable, at least in sections. The wall casing forms both an access-side cover section that closes the longitudinal slot and a bottom-side support base that rests on the bottom of the receiving groove. This gives the elastomer hollow profile a tubular shape with a rotationally asymmetrical cross-section.

[0009] In a further embodiment of the invention, the cover section is designed to be more rigid than the side flanks. In the unloaded functional position, the cover section closes the longitudinal slot at least largely flush. The more rigid design of the cover section can be achieved either by a thicker wall thickness of the elastomer hollow profile for the cover section or by a different material selection for the cover section. In the latter case, the cover section is then formed together with the side flanks and the support base by coextrusion or by a similar process in which the elastomer hollow profile is manufactured jointly from two different materials with different physical properties.

[0010] In a further embodiment of the invention, the cover section has a greater wall thickness than the side flanks. This inevitably results in greater rigidity for the cover section than for the side flanks.

[0011] In a further embodiment of the invention, the side flanks are made of a softer elastomer material than the cover section. This embodiment can also be formed by coextrusion or another common manufacturing process.

[0012] In a further embodiment of the invention, the side flanks are each provided with at least one predetermined bending point. This predetermined bending point enables a defined bending and thus a defined elastic deformation of the elastomer hollow profile.

[0013] In a further embodiment of the invention, additional predetermined bending points are provided at transition areas between the cover section and the side flanks and / or between the side flanks and the support base. This embodiment enables further improved elastic deformation of the elastomer hollow profile as soon as a load is exerted on the cover section from an access side, in particular by inserting a fastening element.

[0014] In a further embodiment of the invention, the at least one predetermined bending point is formed by a material weakening, in particular by a wall thickness that is smaller than adjacent areas. The material weakening is preferably formed by a groove or a channel or a notch in the wall of the elastomer hollow profile, wherein the corresponding groove, channel, or notch extends in the longitudinal direction of the elastomer hollow profile.

[0015] In a further embodiment of the invention, the at least one predetermined bending point is formed by a closed channel integrated into the respective side flank. The channel extends longitudinally in the wall of the elastomer hollow profile and, viewed in cross-section, forms an eyelet in the wall shell of the elastomer hollow profile.

[0016] In a further embodiment of the invention, the channel-like support area is formed by a recess formed in the support base. The wall shell of the elastomer hollow profile is thus drawn inward into the interior of the hollow chamber in the area of ​​the support base, with the recess preferably being matched in terms of its cross-section to a cross-section of the hump-shaped profile section of the load-bearing profile in order to enable the elastomer hollow profile to be securely positioned on the profile section of the receiving groove of the load-bearing profile.

[0017] In a further embodiment of the invention, the channel-like support area is formed by two support webs that are spaced parallel to one another and project downwards from the support base, which are integrally formed on the support base. This embodiment is provided as an alternative to the previously described recess. The two support webs flank side areas of the hump-shaped profile section of the load carrier profile in the inserted state.

[0018] In a further embodiment of the invention, the load-bearing profile has a receiving groove with side walls that bulge toward opposite sides. The side walls of the receiving groove therefore do not extend downward in a straight line, as in the prior art, but rather, viewed in cross-section, are concavely curved outward, allowing the elastomer hollow profile with its spherical wall shell to deform into the bulged side walls upon elastic deformation.

[0019] In a further embodiment of the invention, the load carrier profile has a hollow channel on each side of the receiving groove - seen in cross-section - wherein the cross sections of the hollow channels on both sides have different dimensions to one another. This embodiment is particularly advantageous if the load carrier profile is used as part of a roof rack arrangement and is mounted in the transverse direction of the vehicle. By designing the load carrier profile with a correspondingly asymmetrical cross-section, a drop-like outer contour for the load carrier profile can be achieved, which is particularly aerodynamically advantageous. The receiving groove arranged centrally between the lateral hollow channels is not affected by this. It is designed to be mirror-symmetrical to a vertical central longitudinal plane that passes centrally through the longitudinal slot of the receiving groove.

[0020] Further advantages and features of the invention emerge from the claims. Preferred embodiments of the invention are described below and illustrated with reference to the drawings. Fig. 1 shows a schematic cross-sectional view of an embodiment of a load carrier arrangement according to the invention, Fig. 2 shows a schematic cross-sectional view of an embodiment of a load carrier arrangement not belonging to the invention, Fig. 3 shows a schematic cross-sectional view of a further embodiment of a load carrier arrangement according to the invention, Fig. 4 schematically shows an elastomer hollow profile for a load carrier arrangement not belonging to the invention similar to the Fig. 1 to 3, Fig. 5 schematically shows, in only partial cross-sectional representation, another embodiment of a load carrier arrangement according to the invention, Fig. 6 in a schematic cross-sectional view of an elastomer hollow profile of an embodiment not belonging to the invention of a load carrier arrangement similar Fig. 2, Fig. 7 shows a schematic cross-sectional view of a further embodiment of a load carrier arrangement according to the invention with an elastomer hollow profile and a merely indicated load carrier profile, Fig. 8 in a schematic cross-sectional view of an elastomer hollow profile of an embodiment not belonging to the invention of a load carrier arrangement according to the invention similar Fig. 2 and Fig. 9 schematically shows in a cross-sectional view an elastomer hollow profile of a further embodiment of a load carrier arrangement according to the invention in a load carrier profile that is only indicated.

[0021] A load carrier arrangement 1 according to Fig. 1 is provided for a roof rack system of a motor vehicle, in particular a passenger car. The load carrier assembly 1 comprises a dimensionally stable load carrier profile 2, which in the illustrated embodiment is made as an extruded profile made of a light metal alloy. The load carrier profile 2 is fastened to a vehicle roof in the vehicle-mounted state and extends in the transverse direction of the vehicle. Advantageously, two such load carrier profiles 2 are fastened to the vehicle roof in parallel and spaced apart from one another.

[0022] The load carrier profile 2 has, in a central area, a receiving groove 4 distributed over its entire length, which is open over its entire length towards an access side, i.e. in this case towards a top side, in the form of a longitudinal slot 5. Fastening elements of the roof rack system can be mounted through the longitudinal slot 5 in the receiving groove in order to be able to mount leisure equipment or other support parts of the roof rack system on the load carrier profile 2. The receiving groove 4 forms an undercut below the longitudinal slot 5. Opposite side walls of the receiving groove 4 are each bulged outwards in a wall section 8, as Fig. 1. The bulged wall section 8 extends into a hollow channel 6, 7 of the load carrier profile 2. The hollow channel 6 is oriented forwards in the direction of travel when the load carrier profile 2 is mounted on the vehicle, whereas the hollow channel 7 within the load carrier profile 2 is oriented rearwards in the direction of travel. Fig. 1 it can be seen that the two hollow channels 6 and 7 are designed differently. The hollow channel 7 - in relation to the state of the load carrier profile 2 mounted on the vehicle - extends further back in the vehicle's longitudinal direction than the width of the hollow channel 6. This results in an asymmetrical shape in the cross section for the load carrier profile 7, in relation to a vertical central longitudinal axis intersecting the receiving groove 4 (to the drawing plane according to Fig. 1).

[0023] The opposite side walls of the receiving groove 4 are bulged mirror-symmetrically to the vertical central longitudinal axis of the receiving groove 4. A bottom 14 of the receiving groove 4 is provided with a hump-shaped profile section, which in cross section is according to Fig. 1 has a rectangular shape and projects upwards into the receiving groove 4.

[0024] An elastomer hollow profile 3, which is designed as a rubber hollow profile, is arranged in the receiving groove 4. The elastomer hollow profile 3 has - seen in cross section - a circumferential wall shell that defines a single hollow chamber within the elastomer hollow profile 3. On an upper side, the wall shell of the elastomer hollow profile 3 is formed by a cover section 9, which in an unloaded functional position of the elastomer hollow profile 3 according to Fig. 1 closes the longitudinal slot 5 flush. From the cover section 9, two side flanks 10 of the wall shell extend diagonally downwards and outwards on opposite sides - also seen in cross-section - which, with their outer sides in the unloaded functional position, rest against a transition between the side flanks and the bulged wall sections 8. The transitions form corner sections of the side walls of the receiving groove 4, at which vertically downwardly projecting side wall sections merge into the bulged wall sections 8. The bulged wall sections 8 are dimensioned such that a free space remains between an outer contour of the wall shell of the elastomer hollow profile 3 in the unloaded functional position and inner surfaces of the receiving groove 4 in the area of ​​the wall sections 8, into which free space the side flanks 10 of the elastomer hollow profile 3 can deflect upon elastic deformation.

[0025] The elastomer hollow profile 3 also has a support base 11 on the bottom side, which rests on the bottom of the receiving groove 4. In the embodiment according to Fig. 1, the support base 11 forms a recess with an approximately rectangular cross-section, which in the assembled functional position according to Fig. 1 is placed onto the profile section 14 of the base of the receiving groove 4. The wall shell of the elastomer hollow profile 3 is convexly curved downwards and toward the center in a transition region 13 from the respective side flank 10 to the support base 11, resulting in an outer contour with an approximately circular arc in cross-section for this transition region 13. The wall thickness of the wall shell of the elastomer hollow profile 3 is the same in the area of ​​the side flanks 10, in the area of ​​the transition sections 13, and in the area of ​​the support base 11. The cover section 9 of the elastomer hollow profile 3, which closes the longitudinal slot 5, is provided with a greater wall thickness than the side flanks 10, the transition sections 13 and the support base 11. On the inside of the hollow chamber and thus on the inside of the wall shell, the elastomer hollow profile 3 also has several predetermined bending lines 12, which are formed by grooves extending along the elastomer hollow profile 3.The wall thickness of the wall shell of the elastomer hollow profile 3 is reduced at the predetermined bending lines 12. The predetermined bending points 12 enable a defined buckling of the elastomer hollow profile 3 into the receiving groove 4 upon elastic deformation of the elastomer hollow profile 3 from above, i.e., from the side of the longitudinal slot 5. Therefore, when a fastening element of the roof rack system is inserted from above through the longitudinal slot 5 into the receiving groove 4, this fastening element inevitably presses the cover section 9 of the elastomer hollow profile 3 inward into the receiving groove 4, whereby the elastomer hollow profile 3 is elastically deformed. This results in deformation and thus buckling, particularly at the predetermined buckling points 12. The cover section 9 is pressed downwards in the direction of the support base 11, whereby the side flanks 10 and the transition sections 13 slide downwards and outwards along the side walls of the receiving groove 4.The support base 11 is held stable in the area of ​​the hump-shaped profile section of the base 13 of the receiving groove 4, so that an elastic displacement of the wall shell only occurs in the area of ​​the side flanks 10 and in the area of ​​the transition sections 13 in the direction of the bulged wall sections 8 of the receiving groove 4. Corresponding inclinations of the side walls in the area of ​​the bulged wall sections 8 are designed in such a way that in the elastically deformed state of the elastomer hollow profile 3 there is no force-fitting inhibition for the elastomer hollow profile 3, ie it is ensured that after the mechanical load from above on the cover section 9 is removed, the elastomer hollow profile 3 automatically returns to its unloaded functional position according to. Fig. 1 resets.

[0026] The following based on the Fig. The embodiments of load carrier arrangements according to the invention described in Figures 2 to 9 correspond in terms of structure and function to the load carrier arrangement 1 according to Fig. 1, so that in order to avoid repetition for the embodiments according to the Fig. 2 to 9 in addition to the disclosure of the embodiment according to Fig. 1. Parts and sections with the same function or construction are designated by the same reference numerals with the addition of different lower case letters a to h for the different embodiments. The following refers to the differences between the embodiments according to the Fig. 2 to 9 received.

[0027] A load carrier arrangement 1a according to Fig. 2 has a dimensionally stable load-bearing profile 2a, which is also made of a light metal alloy. The load-bearing profile 2a is provided with a receiving groove 4a having a substantially rectangular cross-section. Side walls 8a of the receiving groove 4a and the base 14a are each flat wall sections that are perpendicular to one another. The longitudinal slot 5a in the receiving groove 4a is delimited by an elastomer hollow profile 3a, which also has only a single, closed hollow chamber. A circumferentially closed wall casing forms the cover section 9a in the area of ​​an upper side, which closes the longitudinal slot 5a. In the area of ​​opposite side flanks 10a extending obliquely outwards and downwards from the cover section 3a and in the area of ​​the flat support base 11a, the wall casing has identical wall thicknesses.

[0028] In the embodiment according to Fig. 3, the load carrier arrangement 1b has a load carrier profile 2b which is designed almost identically to the load carrier profile 2a according to Fig. 2. The only difference is that the bottom 14b of the receiving groove 4b is analogous to the embodiment according to Fig. 1 is provided with a hump-like profile section. The elastomer hollow profile 3b is designed largely identically to the elastomer hollow profile 3b with the difference that the support base 11b is provided with a recess through which transition sections 13b are created between the side flanks 10b and the support base 11b. This recess ensures a secure positioning of the elastomer hollow profile 3b on the hump-shaped profile section of the base 14b of the receiving groove 4b, so that a precise alignment of the elastomer hollow profile 3b in the receiving groove 4b is achieved in the same way as in the embodiment according to Fig. 1 is the case.

[0029] The elastomer hollow profile 3c, which fits into a receiving groove of a load carrier profile according to Fig. 2 is formed by two closed hollow chambers that are positioned one above the other in the shape of a figure eight. This results in two closed wall shells that are integrally connected to one another by being manufactured together by coextrusion or in a similar manner during the production of the elastomer hollow profile 3c. An upper hollow chamber with an oval cross-section has a smaller width and height than the lower hollow chamber, which also has an oval cross-section. A bottom surface of the lower hollow chamber forms the supporting base of the elastomer hollow profile 3c, and an upper surface of the upper hollow chamber of the elastomer hollow profile 3c forms the covering section of the elastomer hollow profile 3c.

[0030] In the embodiment according to Fig. 5, the elastomer hollow profile 3d is in a receiving groove 4d of a load carrier profile not shown in detail, analogous Fig. 3. The elastomer hollow profile 3d has a single hollow chamber, with a wall shell having an outer contour in cross-section with several, intertwined shell sections. The various shell sections form a dome shape in the area of ​​an upper side, which transitions into two spherical support foot areas, which accommodate the profile section of the base 14d of the receiving groove 4d between them. The transition of the upper, dome-shaped shell section to the support foot sections occurs via an angular indentation, which inevitably forms a predetermined bending line upon elastic deformation of the elastomer hollow profile 3d.

[0031] The elastomer hollow profile 3e according to Fig. 6 is for a load carrier profile 2a according to Fig. 2 and has a largely trapezoidal cross-section. Two side flanks 10e extending diagonally outwards and downwards are connected to an upper cover section 10e, which are provided with wall sections 12e made of a softer elastomer material. This is indicated by the colored sections in Fig. 6. These softer material sections, when subjected to mechanical pressure from above on the cover section 9e, cause the side flanks 10e to buckle and deflect inward into the interior of the individual hollow chamber of the elastomer hollow profile 3e. A support base 11e rests flatly on a corresponding base of the receiving groove of the load-bearing profile (not shown).

[0032] The elastomer hollow profile 3f is used for a load carrier arrangement in which a load carrier profile has a hump-shaped profile section on the bottom side in the area of ​​a receiving groove 4f. The thus formed bottom 14f of the receiving groove 4 with a rectangular, hump-shaped profile section serves to secure the position of an elastomer hollow profile 3f, which is essentially tubular with a single hollow chamber. A corresponding wall shell of the elastomer hollow profile 3f is in the unloaded functional position according to Fig. 7 is provided with a trapezoidal cross-section, with a cover section 9f being curved in an arcuate manner and merging into opposite, downwardly and outwardly extending side flanks 10f. The side flanks 10f terminate, via arcuate transition regions of the wall shell, in a support base 11f, which is provided with downwardly projecting, integrally formed support webs 13f. The support webs 13f flank the hump-shaped profile section of the base 14f of the receiving groove 4f in the inserted functional state of the elastomer hollow profile 3f.

[0033] Based on the Fig. 7 shows that both the support webs 13f and the cover section 9f of the elastomer hollow profile 3f, which is curved in cross-section, are colored. Both the cover section 9f and the support webs 13f are made of a stiffer elastomer material than the remaining area of ​​the elastomer hollow profile 3f. These colored sections can either have a greater wall thickness or be made of an elastomer material with greater stiffness than the side flanks 10f. This ensures that the support webs 13f remain securely supported on the hump-shaped profile section of the base 14f of the receiving groove 4f, even in the event of elastic deformation.In addition, due to the higher rigidity of the cover section 9f of the elastomer hollow profile 3f, it is ensured that in the event of an elastic deformation by inserting a fastening element from above into the receiving groove 4f, the cover section 9f reliably deflects downwards.

[0034] The elastomer hollow profile 3g according to Fig. 8 essentially corresponds to the elastomer hollow profile 3e according to Fig. 6. The key difference is that the material weakening of the opposing side flanks 10g is not achieved by softer material sections, but rather by the geometric design of these side flanks 10g. In this case, as seen in cross-section, an eyelet is provided in each side flank 10g, each of which forms a closed channel extending in the longitudinal direction of the elastomer hollow profile 3g. This creates predetermined bending points for the side flanks 10g of the elastomer hollow profile 3g in the area of ​​these "eyelets."

[0035] The elastomer hollow profile 3h according to Fig. 9 corresponds largely to the elastomer hollow profile 3d in terms of its outer contour - based on a cross-section of the elastomer hollow profile 3h. The essential difference is that the elastomer hollow profile 3h is formed by three closed hollow chambers, of which an upper hollow chamber has an approximately circular cross-section. Two support foot sections adjoin this upper hollow chamber, analogous to the elastomer hollow profile 3d according to Fig. 5, wherein these support leg sections are integrally formed on the closed annular shell of the upper hollow chamber of the elastomer hollow profile 3h. The support leg sections flank a hump-shaped profile section of the bottom 14h of the receiving groove 4h on both sides. All three hollow chambers are elastically deformable, with an upper side of the elastomer hollow profile 3h preferably being provided with a cover section that is more rigid than the other wall sections.
