DETAILED DESCRIPTION OF EMBODIMENTS

[0097] In FIG. 1, a cargo carrier 2 according to an embodiment of the invention is shown in a perspective view from above. The cargo carrier 2 comprises a base (not visible in FIG. 1), an openable and closable lid 20 and an add-on portion 4 that is attached to both of the base and to the lid 20. The lid 20 may be one of the reinforced lids 20 described with respect to FIGS. 16 to 25. The lid 20 is hingedly coupled with the base. The add-on portion 4 is fixedly coupled with the lid 20 and with the base, respectively.

[0098] The add-on portion 4 may add stability contributing to an increase in overall stiffness of the cargo carrier. The reinforced front portion 21 of the reinforced lids 20 described with respect to FIGS. 16 to 25 may add additional stability contributing to an increase in overall stiffness of the cargo carrier 2 in addition to the add-on portion 4.

[0099] The add-on portion 4 comprises a bridging portion 30 and a spoiler portion 50. The bridging portion 30 is attached to the base and the spoiler portion 50 is attached to a rear portion of the lid 20. As the lid 20 is openable and closable, the bridging portion 30 and the spoiler portion 50 are not interconnected to allow movability of the lid 20 relative to the base.

[0100] The bridging portion 30 is designed as a frame 40 horizontally surrounding the base. The integrally formed frame 40 comprises a plurality of bridging portions, a front bridging portion 35, a rear bridging portion 36 and two lateral bridging portions 37. Alternatively, the frame can be assembled from these bridging portions 35, 36, 37 which can be provided by at least two separate bridging parts and which can be connected to each other. A left lateral bridging portions 37 is arranged between a left lateral portion of the front bridging portion 35 and a left lateral portion of the rear bridging portion 36. A right lateral bridging portions 37 is arranged between a right lateral portion of the front bridging portion 35 and a right lateral portion of the rear bridging portion 36. The terms “front”, “rear”, “left” and “right” refer to a direction of motion D of the cargo carrier 2 when mounted on a vehicle roof (not shown in the Figures).

[0101] The cargo carrier 2 as shown in FIG. 1 comprises a longitudinal central axis A-A. This axis A-A runs horizontally in a vertical plane of symmetry regarding the outer shape of the lid 20, the base, the bridging portion 30 and/or the spoiler portion 50 of the add-on portion 4. In other words, these components comprise a mirror-symmetry with respect to the vertical plane of symmetry, such that a symmetrical aerodynamic design axis is provided.

[0102] In FIG. 2, the cargo carrier 2 according to the embodiment of FIG. 1 is shown from its left side. The base 10 is partly shown. The outer shape of the cargo carrier 2 is designed as follows: A first substantially flush transition T1 is provided between a front portion of the lid 20 and the front bridging portion 35. Second substantially flush transitions T2 are provided between lateral portions of the lid 20 and each of the lateral bridging portions 37. A third substantially flush transition T3 is provided between an outer surface 51 of the spoiler portion 50 to the rear bridging portion 36. Substantially flush passages T4 are provided between the front bridging portion 35 and each of the lateral bridging portions 37, which can be substantially fourth flush transitions in case of the frame being assembled from separate bridging parts. Substantially flush passages T5 are provided between the rear bridging portion 36 and each of the lateral bridging portions 37, which can be substantially fifth flush transitions in case of the frame being assembled from separate bridging parts. A sixth substantially flush transition T6 is provided between the spoiler portion 50 and a rear portion of the lid 20. A longitudinal silhouette S1, resulting from a longitudinal section of the cargo carrier 2, comprises in clockwise direction transitions T1, T6 and T3 wherein the silhouette S1 is thus designed as a substantially flush contour of the cargo carrier 2.

[0103] The spoiler portion 50 comprises a gripping portion 52. The cargo carrier 2 comprises a lateral handle 42 and a lock part 44. The lateral handle 42 is arranged on the lid 20 for opening and closing the lid 20 manually. The lock part 44 is arranged on the base 10 for engaging and locking the closed lid 20. One of the lateral bridging portions 37 of the frame 40 comprises a lock recess 45 allowing access to the lock part 44 even though the base 10 is surrounded by the bridging portion 30.

[0104] The cargo carrier 2 further comprises fixation members 60 attached to bottom portions of the base 10. These fixation members 60 allow a fixation of the cargo carrier 2 on respective cross members (not shown) mounted on a vehicle roof. Regarding a convex hull 7 enveloping the base 10, the lid 20 and the add-on portion 4, all fixation members 60 are located inside of this convex hull 7.

[0105] In FIG. 3, the cargo carrier 2 is shown in a perspective view from below. The fixation members 60, e.g. four fixation members 60, are attached to the base 10 in a longitudinally shiftable manner for being adapted to differently spaced cross members. Besides that, ground contact sections 62 are arranged on the base 10, e.g. two on a front portion of the base 10 and two on a rear portion of the base 10. Alternatively, ground contact sections 62 can be arranged on the add-on portion 4, more specifically on the bridging portion 30, e.g. two ground contact sections 62 on the front bridging portion 35 and two ground contact sections 62 on the rear bridging portion 36.

[0106] As further shown in FIG. 3, seventh substantially flush transitions T7 are provided between the front bridging portion 35 and the base 10, between the rear bridging portion 36 and the base 10 and between each of the lateral bridging portions 37 and the base 10. A cross silhouette S2, resulting from a cross section of the cargo carrier 2 (shown in FIG. 8) comprising second transitions T2 (described with respect to FIG. 2) and seventh transitions T7 is thus designed as a further substantially flush contour of the cargo carrier 2.

[0107] In FIG. 4, the cargo carrier 2 is shown in an exploded view, wherein top down the lid 20 with the spoiler portion 50 of the add-on portion 4, the base 10 and the bridging portion 30 of the add-on portion 4 are each shown separately. The lid 20 comprises an edge portion 22 at a bottom side of the lid 20. The base 10 comprises a rim portion 12 on its top side. Inside of the base 10, an interior space 11 is provided for stowing goods (not shown) inside the cargo carrier 2, more specifically inside the base 10 and/or the lid 20. The bridging portion 30 comprises the front bridging portion 35, the rear bridging portion 36 and the two lateral bridging portions 37 forming the frame 40.

[0108] The lid 20 is coupled to the base 10 by at least one hinge (not shown). The bridging portion 30 of the add-on portion 4 is engaged with the base 10 and the spoiler portion 50 of the add-on portion 4 is engaged with the lid 20 when the add-on portion 4 is added to the base 10 and lid 20, respectively. A manufacturing process of the cargo carrier 2 may thus comprise respective engagements steps.

[0109] In FIG. 5, the cargo carrier 2 is shown in the longitudinal vertical section A-A as indicated in FIG. 1. A detail C of FIG. 5 with respect to the bridging portion 30, more specifically with respect to the front bridging portion 35, attached to the base 10 is marked and is further described with respect to FIG. 6 and a detail D of FIG. 5 with respect to the spoiler portion 50 attached to the lid 20 is marked and is further described with respect to FIG. 7. Fixation members 60 are slidably attached to the base 10.

[0110] In FIG. 6, detail C of FIG. 5 is shown. In the closed state of the lid 20, the edge portion 22 of the lid 20 rests on the rim portion 12 of the base 10. The bridging portion 30, more specifically the front bridging portion 35, engages from below with the base 10, more specifically into the rim portion 12. Besides that, the bridging portion 30, more specifically the front bridging portion 35, covers a bottom edge portion 9, more specifically a front bottom edge portion, of the base 10.

[0111] A part of a convex hull 6 of the base 10 and the lid 20 is schematically shown, enveloping the base 10 and the lid 20. The bridging portion 30, more specifically the front bridging portion 35, extends outwards from the base 10 and protrudes beyond the convex hull 6. In other words, a sub-portion of the front bridging portion 35 is located within the convex hull 6, wherein this sub-portion is engaged with the rim portion 12 of the base 10, and a further sub-portion of the front bridging portion 35 is located outside of the convex hull 6, wherein this sub-portion provides the substantially flush transitions T1, T7 between the front bridging portion 35 and the lid 20 and between the front bridging portion 35 and the base 10. As further shown in FIG. 6, a profile of the bridging portion 30, more specifically of the front bridging portion 35, is substantially formed as a polygonal chain. Alternatively or additionally, the profile of the bridging portion 30 can be curved.

[0112] In FIG. 7, detail D of FIG. 5 is shown. In the closed state of the lid 20, the rear bridging portion 36, is engaged from below with the base 10, more specifically with the rim portion 12. The rear bridging portion 36 covers a rear bottom edge portion of the base 10. The convex hull 6 of the base 10 and lid 20 of FIG. 6 is again shown in FIG. 7. The bridging portion 30, more specifically the rear bridging portion 36, extends outwards from the base 10 and protrudes beyond the convex hull 6. Furthermore, also the lateral bridging portions 37 can protrude beyond the convex hull 6 (not shown in FIGS. 6 and 7).

[0113] In other words, a sub-portion of the rear bridging portion 36 is located within the convex hull 6, wherein this sub-portion engages with the rim portion 12 of the base 10, and a further sub-portion of the rear bridging portion 36 is located outside of the convex hull 6, wherein this sub-portion provides the substantially flush transitions T3, T7 between the rear bridging portion 36 and the spoiler portion 50 and between the rear bridging portion 36 and the base 10. The flush transition T3 is thus further provided between the frame 40 and a rear portion of the spoiler portion 50. As further shown in FIG. 7, a profile of the rear bridging portion 36 is substantially formed as a polygonal chain. Alternatively or additionally, this profile can be curved. The spoiler portion 50 may be bolted or riveted to the lid 20, preferably adjacent to the flush transition T6.

[0114] Regarding a profile of the spoiler portion 50 as partly shown in FIG. 7, the profile comprises a wing-shaped contour arranged to the rear of the cargo carrier 2. The contour is substantially formed as a polygonal chain having a substantially triangular base shape as shown in FIG. 7. Additionally or alternatively, the contour can be curved. A substantially flat rear portion of the lid 20 is thus elongated in rearward direction of the cargo carrier 2. These shapes are provided by adding the spoiler portion 50 to the lid 20.

[0115] In FIG. 8, the cargo carrier 2 is shown in a cross section B-B as indicated in FIG. 2. Regarding the add-on portion 4, a detail E of FIG. 8 with respect to the bridging portion 30 attached to the base 10, more specifically to one of the lateral bridging portions 37, is marked and is further described with reference to FIG. 10. Substantially flush transitions T2, T7 between the lateral bridging portion 37 and the lid 20 and between the lateral bridging portion 37 and the base 10, as already described with respect to FIGS. 2 and 3 are also shown in FIG. 8. The cross silhouette S2 provides a substantially flush cross section of the cargo carrier 2.

[0116] In FIG. 9, the cargo carrier 2 is shown in a further cross section C-C as further indicated in FIG. 2. As shown in FIG. 9, the lid 20 is openable and closable on each of both lateral sides of the cargo carrier 2 with a respective lock and hinge mechanisms 46 arranged inside of the cargo carrier 2. A handle 42 is attached to the lid 20 on both lateral sides of the cargo carrier 2. Furthermore, a lock part 44 and a respective lock recess 45 within the frame 40 are arranged to the base 10 on both lateral sides of the cargo carrier 2. Adjacent to the lock recess 45, the bridging portion 30 is divided into an upper portion 37a of the lateral bridging portion 37 and into a lower portion 37b of the lateral bridging portion 37.

[0117] In FIG. 10 detail E of FIG. 8 is shown. The second substantially flush transition T2 is provided between an outer surface 23 of the edge portion 22 of the lid 20 and an outer surface 31 of the bridging portion 30, more specifically between an outer surface 23 of a lateral edge portion 22 of the lid 20 and an outer surface 31 of a lateral bridging portion 37.

[0118] The seventh substantially flush transition T7 is provided between the outer surface 31 of the bridging portion 30 and a lower outer surface 15 of the base 10. Alternatively, the seventh substantially flush transition T7 can be provided between the outer surface 31 of the bridging portion 30 and an outer surface 14 of a side wall 16 of the base 10. Regarding an attachment of the bridging portion 30 to the base 10 and regarding a resting of the lid 20 on the base 10, detail F is marked in FIG. 10 and is further described in FIG. 11.

[0119] In FIG. 11, detail F of FIG. 10 is shown. In the closed state of the lid 20, an inner surface 24 of the edge portion 22 of the lid 20 rests on an outer surface 13 of the rim portion 12 of the base 10. A substantially flush edge transition T8 (also indicated in FIGS. 2 and 3) is provided between an end portion of the edge portion 22 of the lid 20 and an end portion of the rim portion 12 of the base 10. Also shown in FIG. 11, the outer surface 31 of the bridging portion 30, more specifically of the lateral bridging portion 37, is substantially flush with the outer surface 23 of the lid 20, wherein a gap is provided at the respective substantially flush transition T7.

[0120] As shown in FIGS. 11 and 12, an upper edge portion 32 of the bridging portion 30 has a first supporting section 33 and a second supporting section 34. The first supporting section 33 and the second supporting section 34 are connected with an intermediate section 38.

[0121] As shown in FIGS. 11 and 13, the rim portion 12 of the base 10 comprises a U-shaped wall portion 17 at an upper end of the base 10, more specifically at an upper end of a side wall 16 of the base 10. The U-shape is provided by curving the wall portion 17 outward and over onto itself. An edge portion 18 of the side wall 16 thus protrudes downwards and is located opposite to a remaining non-curved portion 18a of the side wall 16. Within a U-portion of the U-shaped wall portion 17, a gap 19 is be provided. The gap 19 is formed between the downwardly protruding edge portion 18 and the opposite portion 18a of the side wall 16.

[0122] As shown in FIG. 11, the first supporting section 33 contacts the edge portion 18 of the side wall 16. The second supporting section 34 contacts the opposite portion 18a of the side wall 16. The first supporting section 33 and the second supporting section 34 is supported against the edge portion 18 of the side wall 16 and against the opposite portion 18a of the side wall 16, respectively. The supporting sections 33, 34 are arranged at different heights within the gap 19, wherein the first supporting section 33 is arranged below the second supporting section 34. Additionally or alternatively, the first supporting section 33 and the second supporting section 34 may be bonded to the edge portion 18 of the side wall 16 and to the opposite portion 18a of the side wall 16 at the respective bracing positions.

[0123] The embodiment of the cargo carrier 2 as shown in FIGS. 1 to 13 comprises an add-on portion 4 that is attached to the base 10 and to the lid 20, wherein an aerodynamically efficient design is provided, particularly demonstrated with respect to the substantially flush transitions and passages T1 to T8 and silhouettes S1 and S2. Further to aerodynamics, an efficient cargo carrier 2 manufacturing assembly for an efficient manufacturing of the cargo carrier 2 is provided accordingly.

[0124] In FIG. 14, an underside of the cargo carrier 2 is shown from below. Two left ground contact sections 62 are arranged substantially in alignment with two left fixation members 60, wherein the two left fixation members 60 are positioned between the two left ground contact sections 62. Two right ground contact sections 62 are arranged substantially in alignment with two right fixation members 60, wherein the two right fixation members 60 are positioned between the two right ground contact sections 62. Both, the ground contact sections 62 and the fixation members 60 are arranged on the base 10. The distance between two rear ground contact sections 62 arranged at a rear portion of the base 10 is greater compared to the distance between two front ground contact sections 62 arranged at a front portion of the base 10. The four ground contact sections 62 together with the fixation members 60 are thus arranged trapezoidal on the underside of the base 10. At an intersection of the base 10 with the bridging portion 30 and the frame 40, respectively, the flush transition T7 is formed between the front bridging portion 35, the rear bridging portion 36 and each of the lateral bridging portions 37 and the base 10.

[0125] In FIG. 15, the cargo carrier 2 is shown in a side view from the left resting on a ground G. The ground G is indicated by a dashed line. While resting on the ground G, the undermost ground contact sections 62 contact the ground G pointwise (two of them are shown in FIG. 15). Regarding the fixation members 60 (four of them are shown in FIG. 15), they do not contact the ground G as they are positioned above the undermost ground contact sections 62.

[0126] In FIGS. 16 and 17 a rear spoiler 5 is shown in an isolated manner. The rear spoiler 5 may be identical with the spoiler portion 50 as described. All features described with respect to the spoiler portion 50 may thus also apply to the rear spoiler 5.

[0127] An outer surface 51 of the rear spoiler 5 comprises a gripping portion 52 for providing a spoiler handle. The rear spoiler further comprises a spoiler attachment portion 53 for adding the rear spoiler 5 to a lid of a cargo carrier (not shown in FIGS. 16 and 17). The rear spoiler 5 further comprise a depression 54 (only shown in FIG. 17) being substantially flush with the gripping portion 52. Furthermore, the rear spoiler comprises a tapering 55 from a front portion 56 of the rear spoiler 5 to a rear portion 57 of the rear spoiler 5. Such a tapered design has the aerodynamic effect of less air turbulences occurring around the spoiler 5.

[0128] In FIGS. 18 and 19, a lid 20 according to an embodiment is shown from below and in perspective from below, respectively. The lid may be generally used for cargo carriers and may in particular be used for a cargo carrier as described before, preferably a cargo carrier with an add-on portion. The lid 20 comprises a front portion 21 and a rear portion as well as an inner surface 24. In the front portion 21, a reinforcing structure 70 is provided on the inner surface 24.

[0129] As is already indicated in FIGS. 18 and 19, the reinforcing structure 70 extends substantially over the entire width of the inner surface 24 of the lid 20 and extends partially downwards towards an edge portion 22 of said lid 20 in the front portion 21 and preferably also in lateral portions of the lid. Accordingly, the reinforcing portion 70 according to this embodiment not only reinforces a top inner wall of the lid 20 but also a side inner wall extending from the top inner wall downwards. However, the reinforcement of the side wall is optional and a reinforcement of the top inner wall can be sufficient.

[0130] Although not shown in FIGS. 18 and 19, the reinforcing structure 70 is located at least at a longitudinal forward position of a foremost lateral portion at which hinges for coupling the lid to the base may be attached to the lid 20. However, a portion of the reinforcing structure 70 may also be located at a longitudinal rear position of the foremost lateral portion at which hinges for coupling the lid to the base may be attached to the lid 20 which adds additional stability in the region of the hinge attachments.

[0131] The reinforcing structure 70 comprises continuous elongate reinforcing sections 72, 73 wherein at least two of the continuous elongate reinforcing sections 72, 73 comprise different main extension directions. In all the embodiments shown in the Figures, the continuous elongate reinforcing sections 72, 73 are arranged such that one of them crosses another one. The continuous elongate reinforcing sections 72, 73 can thus form different patterns which create additional stability when applied to the front portion 21 of the lid. Furthermore, although not indicated in some of the Figures, the continuous elongate reinforcing sections 72, 73 preferably extend over substantially the entire width of the lid.

[0132] According to the embodiments of the Figures, the continuous elongate reinforcing sections 72, 73 are embodied as protrusions formed on or in a sheet 71 which is manufactured according to the dimensions of the front portion 21 of a lid 20 to which it is mounted. The protrusions may be created by directly and integrally forming a sheet 71 with the protrusions, for example by forming ribs on the sheet 71, or by forming a sheet 71 with grooves on one side resulting in protrusions on the opposite side. Such a sheet may be manufactured by moulding plastics.

[0133] In FIGS. 20 to 24, different possible patterns formed by the continuous elongate reinforcing section 72, 73 are shown.

[0134] In FIG. 20, a mesh-like structure is shown in which a first group of elongate reinforcing sections 72 are formed straight and parallel with respect to each other and a second group of elongate reinforcing sections 73 are formed straight and parallel with respect to each other but extend at an angle with respect to the first group of elongate reinforcing sections 72. In the embodiment, the elongate reinforcing sections 72, 73 are arranged such that one or more rhombic areas are formed between four of the elongate reinforcing sections. Such a reinforcing structure provides enhanced rigidity as the elongate reinforcing sections 72, 73 extend over the sheet in an unbroken, continuous manner and the rhombic areas provide contact surfaces by means of which the sheet 71 can be bonded to the inner wall.

[0135] In FIG. 21, a crossing point of two elongate reinforcing sections 72, 73 is shown. The elongate reinforcing sections 72, 73 again cross each other at an angle and both extend along specific paths P1, P2, respectively. In the embodiment, the elongate reinforcing sections 72, 73 meet at an angle of substantially 90 degrees but it is noted that different angles may be realized. As can be gathered from FIG. 21, the elongate reinforcing sections 72, 73 meet each other in a manner that portions of them continue on opposite sides without substantial offset. The course of such elongate reinforcing sections 72, 73 may be referred to as regular, continuous reinforcing sections as they continue on their respective paths P2, P3.

[0136] A slight modification is shown in FIG. 22. Here, the reinforcing section 72 is partially continuous as it continues on a path P2 lying within the width of the reinforcing section 72 as is indicated. In other words, there is a slight offset in the portions on opposite sides of the reinforcing section 73 that is crossed, but not to an extent that the portions do not overlap any more. For example, a configuration in which the offset of portions of one elongate reinforcing section on opposite sides of a reinforcing section which is crossed is such that the one of the portions is not at least partially located in a region limited by two imaginary extensions of lateral outer portions through the crossed elongate reinforcing section, such a configuration of an elongate reinforcing section may be regarded as not continuous. Accordingly, while the configuration as shown in FIG. 22 is still regarded to have a continuous reinforcing section 72 a further offset between the portions on opposite sides would lead to a non-continuous configuration.

[0137] FIG. 23 shows an arrangement in which elongate reinforcing sections 72, 73 are arranged cross to each other in a sheet 71. More precisely, in the configuration according to FIG. 23, two elongate reinforcing sections 72 extend substantially parallel in the longitudinal direction and at substantially the same distance from a middle axis of the lid 20. The two longitudinal reinforcing sections 72 extend up to the front end of the lid and partially downwards along an inner side wall surface of the lid 20. A transversal reinforcing section 73 crossing both of the longitudinal reinforcing sections 72 is provided at a predetermined distance from the front end of the lid 20. The transversal reinforcing section 73 is continuous and unbroken over substantially the entire width of the lid. The transversal reinforcing section 73 comprises a curved shape in which a middle portion is nearer to the front end of the lid compared to the end portions thereof. An area 75 limited by the front end portions of the longitudinal elongate reinforcing sections 72 and a forward end portion of a middle section of the curved transversal elongate reinforcing section 73 may be used for an attachment of a lid lifter and may thus form a fixation area 75 having a support portion 76 formed by a double layer of sheet 71 and lid wall. On a rear side of the transversal elongate reinforcing section 73 similar areas at least partially limited by the elongate reinforcing sections may serve as fixation portions 74 for bonding the sheet 71 to the inner wall 24 of the lid 20 or may serves as fixation areas 77 which in addition to being bondable to the lid 20 may serve as fixation areas defining a support portion 78 configured for an attachment of lateral foremost hinges of the lid 20. Instead of or in addition to a curved transversal elongate reinforcing section 73, a straight transversal elongate reinforcing section may be provided.

[0138] FIG. 24 shows a configuration in which instead of the curved transversal elongate reinforcing section, multiple straight transversal reinforcing sections 73 are provided. Again, suitable areas 74, 75 as described before are created between the elongate longitudinal and transversal reinforcing sections 72, 73.

[0139] In FIG. 25, the lid 20 is shown from below. In the lid 20, a reinforcing structure 70 is provided on the inner surface 24 of the lid 20. The further reinforcing structure 70 may be configured, at least in part, as the reinforcing structure 70 described with respect to FIGS. 18 to 24. The further reinforcing structure 70 extends substantially over the entire width of the inner surface 24 of the lid 20. The reinforcing structure 70 extends partially downwards towards the edge portion 22 of the lid 20 in the front portion 21 and preferably also rearwards towards a middle portion 25 of the lid 20.

[0140] The lid 20 can comprise an additional reinforcing structure 83 attachable to the middle portion 25 of the lid 20, for example in the area at which middle hinges for coupling the lid to a base can be provided. The reinforcing structure 70 and the additional reinforcing structure 83 are separate parts. The additional reinforcing structure 83 laterally extends over the entire width of the inner surface 24 of the lid 20, wherein the additional reinforcing structure 83 may interconnect the edge portion 22 of the lid 20 providing an enhanced overall stability of the lid 20. The additional reinforcing structure 83 may be at least partly configured as one of the described transversal reinforcing sections 73 of one of the described reinforcing structures 70.

[0141] In FIGS. 26 and 27, the reinforcing structure 70 is shown from below. Also the reinforcing structure 70 comprises continuous elongate reinforcing sections 72, 73 forming another pattern creating additional stability similar to the pattern shown in FIG. 23, wherein the elongate reinforcing sections 72, 73 are arranged flush with each other towards the rear of the reinforcing structure 70. The reinforcing structure 70 comprises a mesh-like structure, in which a first group of elongate reinforcing sections 72 are formed straight and parallel with respect to each other and a second group of elongate reinforcing sections 73 are formed in a curved manner and not necessarily parallel with respect to each other but extend at an angle with respect to the first group of elongate reinforcing sections 72. Besides the above said with respect to FIG. 26, the continuous elongate reinforcing sections 72, 73 of the reinforcing structure 70 may be configured, at least in part, as the continuous elongate reinforcing sections 72, 73 described with respect to FIGS. 18 to 24. Thus, the continuous elongate reinforcing sections 72, 73 may be embodied as protrusions formed on or in the sheet 71 described there.

[0142] FIGS. 26 and 27 show an arrangement in which the elongate reinforcing sections 72, 73 are arranged cross to each other in the sheet 71. In the configuration according to FIGS. 26 and 27, two elongate reinforcing sections 72 extend substantially parallel in the longitudinal direction and at substantially the same distance from the middle axis of the lid 20. Both of the two longitudinal reinforcing sections 72 extend up to the front end of the lid and partially downwards along the inner side wall surface of the lid 20 up to a transversal reinforcing section 73, wherein the two longitudinal reinforcing sections 72 may terminate flush with the transversal reinforcing section 73. The transversal reinforcing section 73 may not be curved in the longitudinal direction. The transversal reinforcing section 73 may however be tapered in the longitudinal direction and/or in the cross direction. A further transversal reinforcing section 73 crossing both of the longitudinal reinforcing sections 72 may be provided at a predetermined distance from the front end of the lid 20. The further transversal reinforcing section 73 may be provided in between the front end of the lid 20 and the transversal reinforcing section 73 that may be flush with the two elongate reinforcing sections 72. The transversal reinforcing section 73 comprises a curved shape in which a middle portion is nearer to the front end of the lid 20 compared to the end portions thereof. At least one of the transversal reinforcing sections 73 of the arrangement is continuous and unbroken over substantially the entire width of the lid. The area 75 (not shown in FIGS. 26 and 27) described with respect to FIGS. 23 and 24 may also be provided according to this arrangement. The same applies to the areas described with respect to FIGS. 23 and 24 serving as fixation portions 74 for bonding the sheet 71 to the inner wall 24 of the lid 20 or serving as fixation areas 77 defining a support portion 78.

[0143] As shown in FIGS. 25 to 27, the elongate reinforcing sections 72, 73 may further comprise curved end portions 85, which may at least in part geometrically follow the shape of the edge portion 22 of the lid 20 in its front end and/or in its lateral sides. Furthermore at least one of the elongate reinforcing sections 72, 73 may further comprise at least one bulging portion 87 shown in FIG. 27, following the shape of the inner surface 24 of the lid 20. The bulging portion 87 may partly scale up the thickness of the at least one of the elongate reinforcing sections 72, 73 by adding an additional bulging volume to a constant thickness of the at least one of the elongate reinforcing sections 72, 73.

[0144] Common to all the latter embodiments is the manufacturing process of the lid 20 comprising the reinforcing structure 70. First, a lid for a cargo carrier is provided and a reinforcing structure 70 comprising elongate reinforcing sections 72, 73 are provided. For that, the elongate reinforcing sections 72, 73 are formed in a separate sheet 71. In the present embodiment, the sheet 71 and the elongate reinforcing sections 72, 73 are integrally moulded from resin moulding, in particular by forming protrusions on the sheet. The thus created reinforcing structure 70 comprising the sheet 71 with integrally formed reinforcing sections 72, 73 is then attached, preferably bonded by gluing, to the inner wall of the lid 20 at a front portion of the lid 20. It is to be noted that due to the fact that the reinforcing structure is created as a separate member and then applied on the lid, existing lids can be retrofitted by attaching such reinforcing structures thereto.

[0145] In the following, a possible first configuration of a cargo carrier and a second configuration of a lid which may be used with a cargo carrier, in particular with a cargo carrier according to the first configuration and/or as described before in the summary portion and the detailed description are represented in itemized structure in addition to the subject matter of the claims.
