Description

[0001] The invention relates to a movable roof for a passenger car, which is adjustable on a body from a closed position to an open position and vice versa, according to the preamble of patent claim 1.

[0002] A folding convertible top for a passenger car is known, DE 40 31 270 C1, which is provided with an outer cover and an inner cover. A convertible top rod is provided between the outer cover and the inner cover, which rod elements execute the closing and opening movements. Between the inner cover, attached to a guide rod of the convertible top rod, and levers of this convertible top rod, a cable system with first cables and second cables operates. These cables are guided through eyelets on one side and tensioned by a tension spring and a tensioning bracket on the other.

[0003] DE 39 14 639 A1 describes a fabric tensioning device for a folding top of a motor vehicle, comprising a top fabric and a headliner. The headliner, made of flexible material, is attached to a main bow and tensioned by means of a cable-like tensioning device.

[0004] DE 10 2007 022 354 A1 discloses a motor vehicle with a roof that can be moved between a closed and an open position, i.e., a retractable type, and which has several consecutively arranged bows. The bows support a convertible top made of flexible material and are adjusted by means of levers of a linkage device provided on each long side of the vehicle. Furthermore, the bows are flat components that are joined together on the sides of the roof facing each other—in the closed position—and form so-called flat bows.

[0005] The object of the invention is to design a movable roof for a passenger car with a convertible top fabric, bows, and an interior trim device such that, in the closed position of the roof, the interior trim device is functionally held between the bows and the operating device. In the open position, the interior trim device should assume a specifically stowed position.

[0006] According to the invention, this object is achieved by the features of patent claim 1. Further features embodying the invention are contained in the subclaims.

[0007] The main advantages achieved with the invention can be seen in the fact that the interior trim elements of the interior trim device are connected to the bows and the operating linkage device in the form of roof side links on the long sides of the body, whereby these interior trim elements assume a securely tensioned or a spatially advantageous stored position both in the closed position and in the open position of the roof. The interior trim elements ideally cover the desired levers and links of the operating linkage device, which are not visible. Also worthy of mention is the cable system comprising several cables, which acts exemplary between the body and the bows. The connection of the interior trim elements to the roof side links ensures in a simple way that the interior trim elements can be moved between the tensioned position and the rest position by means of the roof links and the cable system.A solution that particularly enriches the technology of movable roofs is achieved if the roof according to the invention - viewed in the direction of travel - comprises a front bow, a first middle bow, a second middle bow, and a rear bow, which are connected to the interior paneling elements via eyelets with several cables of the cable system. This is further supported if the bows are formed by surface bows placed next to one another in the closed position of the roof, and a first eyelet is attached to the body, a second eyelet to the rear bow, a third eyelet to the second middle bow, a fourth eyelet to the first middle bow, and a fifth eyelet to the front bow. Finally, it is also advantageous if the cables are attached to the interior paneling elements and pass through the eyelets or are held by them.

[0008] The drawing shows an embodiment of the invention, which is explained in more detail below.

[0009] It shows Fig. 1 a schematic oblique view from the rear right top of a roof of a passenger car, Fig. 2 a view approximately corresponding Fig. 1 with a schematically illustrated interior lining device, on a larger scale, Fig. 3 a view in the direction of arrow A of the Fig. 1 on a larger scale and with the roof in the closed position, Fig. 4 a view according to Fig. 3 with the roof in an intermediate position, Fig. 5 a view corresponding Fig. 3 with the roof in the open position.

[0010] Of a passenger car 1, only a movable roof 2 is shown, which is supported by a base body of a body - not shown. The roof 2 can be moved from a closed position Schst - Fig. 1, Fig. 2 and Fig. 3- in an open position east - Fig. The roof 2, which can be adjusted 5-fold and vice versa, extends between an upper cross member 3 of a windshield frame and a rear section 4 of a belt line 5 of the body, running in a sloping curve between the upper cross member 3 and the rear section 4, resulting in a hatchback shape. A flexible top fabric 6 rests on bows which, viewed in the direction of travel B, are formed by a front bow 7, a first center bow 8, a second center bow 9, and a rear bow 10.

[0011] The bows 7, 8, 9, and 10 are designed as so-called flat bows, which are flat components. The flat bows each span sections of a passenger compartment 11 and are joined at the mutually facing end areas 12 and 13; 14 and 15; and 16 and 17 at joints 18, 19, and 20. Fig. 2. On a side 21 facing a passenger compartment 11, an interior trim device 22 partially covers the convertible top fabric 6 and an actuating device 23, of which only the levers 24 and roof side links 25 are shown in principle. A cable system 26 interacts with the interior trim device 22 and the roof side links 25 of the actuating device 23. Furthermore, the bows 7, 8, 9, and 10, or the flat bows, are delimited by roof side supports 27 and 28. Fig. 1-, which in the open position east of the roof 2 are moved separately from the said bows into a rear space of the structure - not shown -.

[0012] The interior trim device 22 is formed by interior trim elements 29 and 30 located outside a central longitudinal plane CC of the passenger car 1, which each extend adjacent to the longitudinal sides Ls of the roof 2, for example, below the roof side supports 27 and 28. The cable system 26 connects the interior trim element 29 to the bows 7, 8, 9, and 10, and it is operatively connected to the curved roof side link 25 of the actuating device 23, such that in the closed position Schst of the roof 2, the interior trim element 29 is tensioned by means of the cable system 26 and the roof side link 25. The interior trim element 29 is connected to the roof side link 25 by gluing, screwing, or the like, along a curved region Bb of the roof side link 25. Fig. 3-.

[0013] The cable system 26, which is held, for example, on the body or a tensioning bracket of the actuating device 23 and at least one of the bows, comprises several cables - first cable 32, second cable 33, third cable 34 and fourth cable 35 - which cooperate with the bows 7, 8, 9 and 10 and the interior trim element 29. The interior trim element 29 is movable by means of the roof side link 25 and the cable system 26 between a tensioning position Spst - Fig. 3- and a rest position Rst movable - Fig. 5-.

[0014] The first cable 32 is attached with a first end 36 to a rear end portion 37 of the interior trim element 29 and with a second end 38 to a remote bow, which in the exemplary embodiment is formed by the first central bow 8. Furthermore, the first cable 32 is held adjacent to the rear end portion 37 of the interior trim element 29 by suitable means, passed through a first eyelet 39 on the body or tensioning bracket, a second eyelet 40 on the rear bow 10, a third eyelet 41 on the second central bow 9, and finally attached to a fourth eyelet 42 of the first central bow 8. A fifth eyelet 43 is attached to the front bow 7, specifically in a zone Z between the rear end portion 12 and a front end portion 44 of said bow 7.

[0015] The second eyelet 40, the third eyelet 41, and the fourth eyelet 42 are attached to the front end regions 17, 15, and 13 of the bows 10, 9, and 8, viewed in the direction of travel B. The second cable 33 is fastened to the interior trim element 29 by a first end 45, penetrates the second eyelet 40, and is held in position by a second end 46 at the third eyelet 41. The third cable 34 is connected to the interior trim element 29 by a first end 47, penetrates the third eyelet 41, and is held in position by a second end 48 at the fourth eyelet 42 of the first center bow 8. Finally, a first end 49 of the fourth cable 35 is firmly attached to the interior trim element 29, passes the fourth eyelet 42 and is then fixed with a second end 50 to the fifth eyelet 43 of the front bow 7.

[0016] To connect the first ends, e.g., 45, of the cables, e.g., 33, to the interior lining element 29, proven methods are used that can withstand even high loads. Material-fit and form-fit connections are suitable for this purpose, and can be designed to suit the load. The stress on end 45 of cable 33 is accommodated by said end 45 forming an approximately right angle to the interior lining element 29 in the tensioned position Spst.
