DETAILED DESCRIPTION

[0022] According to FIG. 1, a vehicle interior 1 of a passenger car, which is not visible in further detail, is provided with a rear seatback arrangement 2. The rear seatback arrangement 2 is arranged in a rear region of the vehicle interior 1 and has a central rest arrangement 3. The central rest arrangement 3 is pivotable in a manner known in principle between a folded-down functional position, as is visible from FIG. 1 and in which the central rest arrangement 3 is provided as an armrest, and a folded-in use position, in which the central rest arrangement 3 is provided as a backrest. In the functional position, the central rest arrangement 3 is oriented substantially parallel to a vehicle longitudinal direction X. In the folded-in use position, the central rest arrangement 3 is oriented substantially vertically and in this respect parallel to a vehicle vertical direction Z. In the functional position, the central rest arrangement 3 releases a region of a through-loading opening 4. The through-loading opening 4 extends through the rear seatback arrangement 2 between a loading space, which is arranged behind the rear seatback arrangement 2 with respect to the vehicle longitudinal direction X and which is not visible in further detail, and the rear region. The through-loading opening 4 is provided for loading through elongate items to be transported such that they can be deposited in their longitudinal extent between the loading space and the rear region of the vehicle interior 1. In the configuration visible with reference to FIG. 1, the through-loading opening is closed by means of a covering device 5.

[0023] In a manner which will be described in more detail, the covering device 5 is pivotable relative to the rear seatback arrangement 2 between a covering position, as is visible with reference to FIG. 1 and in which the covering device 5 closes the through-loading opening 4, and a release position, in which the covering device 5 releases the through-loading opening 4. In additionand in a manner which will likewise be described in further detailthe central rest arrangement 3 is supported on the covering device 5 so as to be pivotable relative to the covering device 5 and thus relative to the rear seatback arrangement 2.

[0024] In order to release the through-loading opening 4 starting from the configuration visible with reference to FIG. 1, the central rest arrangement 3 is first of all pivoted upward from the functional position about a pivot axis extending substantially parallel to a vehicle transverse direction Y and in this way transferred into the use position. In a subsequent step, the covering device 5 is unlocked from the rear seatback arrangement 2 in a manner known in principle and is pivoted forward about an axis, which extends substantially parallel to the vehicle transverse direction Y and is arranged in a lower end region of the covering device 5, until an approximately horizontal orientation is reached and the through-loading opening 4 is substantially completely released.

[0025] Details of the structural and functional design of the covering device 5 are visible with reference to FIGS. 2, 3 and 5 to 6b.

[0026] The covering device 5 has a first housing shell 6 and a second housing shell 7 which are each produced from plastic and joined together to form a substantially rectangular covering cassette 8. In the present case, the housing shells 6, 7 are each produced as plastic injection-molded components and configured to be substantially thin-walled. The housing shells 6, 7 are connected to one another in a force- and/or form-fitting manner by means of latching elements 9, 10 which are designed to be complementary with one another, and thus form the covering cassette 8. Alternatively, or in addition, the housing shells 6, 7 can be connected to one another in an integrally bonded manner by means of a plastic welding process which is known in principle.

[0027] A reinforcing arrangement 14 which is produced from metal and has two reinforcing elements 12, 13 is provided in an interspace 11 formed between the housing shells 6, 7. The reinforcing arrangement 14 is connected to the covering cassette and provided for mechanical reinforcement thereof in a manner which will be described in further detail. In addition, the reinforcing arrangement 14 is provided, on the one hand, for the pivotable vehicle-mounted connection of the covering cassette 8 to the rear seatback arrangement 2 surrounding the through-loading opening 4 and, on the other hand, for the pivotable support of the central rest arrangement 3 on the covering device 5.

[0028] The reinforcing elements 12, 13 are each produced in the form of a longitudinal profile. As is visible in particular with reference to FIGS. 5 to 6b, the longitudinal profiles 12, 13 are joined together with the covering cassette 8 so as to extend substantially in the longitudinal direction L of the covering cassette 8 and to be separated from one another. More precisely, the longitudinal profiles 12, 13 are each joined together with the housing shell 6 of the covering cassette 8. The longitudinal profiles 12, 13 are each produced in one piece. There is no direct joining connection, in particular no welded connection, between the longitudinal profiles 12, 13. Instead, the longitudinal profiles 12, 13 are spaced apart from one another and each joined separately to the housing shell 6. The longitudinal profiles 12, 13 each extend substantially over the entire length of the covering cassette 8 and are arranged substantially mirror-symmetrically to an imaginary center longitudinal plane of the housing shell 6.

[0029] Furthermore, the longitudinal profiles 12, 13 are each produced in the form of a cut and bent sheet metal component and in this respect are cut from sheet metal and multiply bent off. The longitudinal profiles 12, 13 substantially correspond in their basic structural design, and therefore, to avoid repetitions, the discussion below will focus primarily on the configuration of the longitudinal profile 13. Here, reference will be made in particular to the coordinate system visible from FIGS. 1 and 2 and to an orientation of the longitudinal profile 13 in the covering position of the covering device.

[0030] The longitudinal profile 13 has a first vertically and transversely extending wall portion 15. The wall portion 15 extends in the vertical direction Z substantially over the entire length of the housing shell 6. In the transverse direction Y, the wall portion 15 is designed to be narrow by comparison with the housing shell 6. A second wall portion 16 and a third wall portion 17 are each provided in the transverse direction Y laterally with respect to the first wall portion 15. The wall portions 16, 17 are bent off forward through approximately 90 with respect to the longitudinal direction X relative to the first wall portion 15. In this respect, the wall portions 15, 16, 17 at least partially form a U-shaped profile cross section. With respect to the vertical direction Z, the wall portions 16, 17 are each designed to be shorter than the first wall portion 15. The third wall portion 17 has a setback in its upper region, with the result that the web height of the wall portion 17 is partially variable in the vertical direction Z. Laterally with respect to the second wall portion 16 there is provided a fourth wall portion 18 which extends parallel to the first wall portion 15. Laterally adjoining the fourth wall portion 18 there is provided a further wall portion which is oriented substantially parallel to the wall portions 16, 17 and designed in the form of a supporting portion 19. The supporting portion 19 is bow-shaped and provided for the pivotable support of the central rest arrangement 3 on the covering device 5. For this purpose, the supporting portion 19 has a bearing pin receptacle 20. The bearing pin receptacle 20 is provided for receiving a pivot pin, which is assigned to the central rest arrangement 3, or a pivot bolt. Furthermore, a connecting portion 21 is provided in a lower end region of the longitudinal profile 13. The connecting portion 21 is arranged both on the first wall portion 15 and on the second wall portion 16 and comprises a bolt receptacle 22 and a pivot pin receptacle 23. The connecting portion 21 is provided for the pivotable vehicle-mounted connection of the covering cassette 8 on the rear seatback arrangement 2. In a state in which the covering cassette is connected as intended to the rear seatback arrangement 2, the reinforcing arrangement 14 is connected to a retaining bracket 24 (FIG. 4) assigned to the rear seatback arrangement 2. For this purpose, the bolt receptacles 22 of the longitudinal profiles 12, 13 are each screwed, riveted or suchlike connected to the retaining bracket 24. The pivot pin receptacle 23 is provided for receiving a pivot pin (not visible in further detail) fixed pivotably to the rear seatback arrangement 2.

[0031] The configuration of the longitudinal profile 12 differs essentially from that of the longitudinal profile 13 in that no fourth wall portion 18 is provided. Instead, the longitudinal profile 12 is configured to be predominantly mirror-symmetrical in a corresponding manner to the longitudinal profile 13 and in this respect has in particular a supporting portion 19 with a bearing receptacle 20 and a connecting portion with a bolt receptacle 22 and a pivot pin receptacle 23.

[0032] The bearing pin receptacles 20 of the longitudinal profiles 12, 13 are oriented coaxially. During a displacement of the central rest arrangement 3 between the functional and use position, the central rest arrangement 3 is pivoted about an imaginary pivot axis extending between the bearing pivot receptacles 20. Accordingly, the pivot pin receptacles 23 of the longitudinal profiles 12, 13 are also oriented coaxially. During a displacement of the covering cassette 8 or of the covering device 5 between the covering and the release position, the covering cassette 8 is pivoted together with the reinforcing arrangement 14 about an imaginary axis extending between the pivot pin receptacles 23.

[0033] As is visible in particular with reference to FIG. 3, the supporting portions 19 each project from the interspace 11 formed between the housing shells 6, 7. In this way, the supporting portions 19 and in particular the bearing pin receptacles 20 for connecting the central rest arrangement 3 to the covering device 5 are freely accessible. Here, the supporting portions 19 are each covered laterally in the transverse direction by means of a side cheek 25 formed on the second housing shell 7.

[0034] To fasten the longitudinal profiles 12, 13 to the first housing shell 6 of the covering cassette 8, they each have a plurality of fastening openings 26. In the case of the longitudinal profile 13, the fastening openings 26 are arranged both in the first wall portion 15 and in the third wall portion 18. The fastening openings 26 are each produced in the form of a circular cylindrical bore.

[0035] As is visible in particular with reference to FIGS. 5 to 6b, the longitudinal profiles 12, 13 are each nonreleasably connected to the covering cassette 8 in a force- and/or form-fitting manner by means of fastening elements 27. More precisely, the longitudinal profiles 12, 13 are each connected to an inner wall portion 28 of the first housing shell 6. It is visible in particular with reference to FIG. 6b that the fastening elements are each designed in the form of a welding dome 27 which is produced from plastic and connected in an integrally bonded manner to the first housing shell 6. Some of the welding domes 27 are arranged on the inner wall portion 28 of the housing shell 6. Further welding domes 27 are arranged on an inner wall portion 29 (FIG. 2) which is offset in the longitudinal direction with respect to the inner wall portion 28. The welding domes 27 serve to produce a force- and/or form-fitting connection between the reinforcing arrangement 14 and the covering cassette. Here, the longitudinal profiles 12, 13 can be joined together with the housing shell 6 in particular in such a way that the longitudinal profiles 12, 13 are first arranged at the intended position of the inner wall 28, 29 of the housing shell 6. The welding domes 27 are subsequently inserted into the fastening openings 26 in a manner known in principle. Here, the welding domes 27 produced from plastic are pressed rotationally onto the housing shell 6 under an axial load. Consequently, the plastic materials of the housing shell 6 and of the welding domes 27 melt locally and undergo an integrally bonded connection.

[0036] A further embodiment of a covering device 5a according to the invention is visible with reference to FIGS. 7a and 7b. Here, the embodiment according to FIGS. 7a and 7b essentially corresponds to the embodiment described above with reference to FIGS. 1 to 3 and 5 to 6b. In order to avoid repetitions, reference is therefore made to the disclosure of the embodiment according to the last-mentioned figures. Only the key differences will be discussed below. Functionally and/or structurally identical portions and parts of the embodiment according to FIGS. 7a, 7b are provided with the same reference signs with the addition of the lower-case letter a. The covering device 5a differs from the covering device 5 essentially in that an inner wall portion 28a of the covering cassette, more precisely of the first housing shell 6a, that is arranged in the transverse direction between the longitudinal profiles 12a, 13a is provided with a ribbing 30. The ribbing 30 has a plurality of ribs 31 oriented transversely to one another. The ribs 31 are connected in one piece to the housing shell 6a, for example by means of plastic injection-molding. Furthermore, the ribs 31 form a regular ribbing pattern with a square basic structure. This is inclined by approximately 45 with respect to a longitudinal direction of the housing shell 6a. Additional reinforcement is achieved by means of the ribbing 30.
