DETAILED DESCRIPTION

(23) In FIGS. 1 to 12, a vehicle construction 10 is illustrated comprising a vehicle body 12 provided with a top arrangement 14. As a synopsis of FIGS. 1 to 14 shows, the top arrangement 14 comprises an edge section 16, which is fixed to the vehicle and surrounds an essentially rectangular top opening 18 which can either be closed (FIG. 1), partially opened (FIG. 3) or mostly opened (FIG. 4) by means of a top opening system 20.

(24) Starting from a rearward wind cowl 22, which can be formed by a top cassette 24, the top arrangement 14 comprises a folding-top section 26 bordering on a top cutout 28, which is part of the top opening 18, at the front. The top cutout 28 can either be closed or opened by means of two lid elements 30 and 32 which are disposed behind one another in the longitudinal direction of the vehicle when in a closed position (FIG. 5) and each comprises a rigid frame 34 or 36 which surrounds a transparent area 38 or 40 formed by a glass pane. In the closed position, the front lid element 30 abuts against a front wind cowl 44 of the top arrangement 14 with its front edge. The frames 34 and 36 of the lid elements 30 and 32 are spanned by a top cover 32 which also forms the top cover of the folding-top section 26 and is formed by a foldable, weather-proof textile material.

(25) In addition to the top cover 42, as can be derived from FIGS. 7 to 12, the folding-top section 26 comprises four bows 46, 48, 50 and 52 which extend in the longitudinal direction of the top and via which the top cover 42 is spanned in the closed position. The bows 46 and 50 are guided via sliders 54 in guide tracks 56 disposed on each of its two sides relative to a vertical longitudinal center plane of the top. In FIG. 7, the guide track disposed on the left-hand side relative to the forward travel direction of the respective vehicle is illustrated in a dashed line. The bows 48 and 52 are connected to the bows 46 and 50, which are guided in the guide tracks 56, via outward-extension springs 58 and 60 and predefine a folding of the top cover 42 in the folding-top section 26 in the opened position of the top opening system 20.

(26) The two lid elements 30 and 32 can be driven by means of a motor arrangement 62 which is accommodated in the top cassette 24. A first motor of the motor arrangement 62 serves for driving front lid element 30 and a second motor of the motor arrangement 62 serves for driving lid element 32.

(27) Relative to the vertical longitudinal center plane of the top, the lid element 30 is provided on each of its two sides with drive kinematics 64 driven by the first motor via a drive cable and comprising a four-joint-arrangement 66 for raising and lowering the lid element 30, said four-joint arrangement 66 being guided in the respective guide track 56 in the longitudinal direction of the top via sliders 68 disposed at a base link. In addition, the drive kinematics 64 comprises an outward-extension lever arrangement 70, by means of which the four-joint arrangement 66 can be displaced and which is linked to the underside of the lid element 30.

(28) Relative to the vertical longitudinal center plane of the top, the lid element 32, which is driven via a drive cable by means of the second motor of the motor arrangement 62, comprises on its underside on each of its two sides a rigidly fixed pivot arm 72, which is guided in a slotted link (not further illustrated) of the guide track 56 via a slider 74, and a support arm 76, which defines a pivot axis of the lid element 32 in the area of the guide track 56 with its slider 78, said pivot axis becoming shifted when displacing the lid element in the longitudinal direction of the vehicle. The pivot movement is initiated by means of the pivot arm 72 when displacing the lid element 32.

(29) The top arrangement 14 is opened by means of the top opening system 20 in the manner described below.

(30) Starting from the closed position illustrated in FIGS. 1, 5 and 7, the front lid element 30 is first unlocked by actuating the first motor and then raised by means of the outward-extension lever arrangement 70. A hook 71 of the outward-extension lever arrangement 70, which is connected to a drive slider 69 and locks the front lid element 30 in the closed position, is secured against pivoting back. The raising movement is guided by the four joint arrangement 66. Subsequently, the frontward lid element 30 can be displaced towards the rear by means of the drive cable driven by the first motor. A base link of the four-joint arrangement 66 is guided in the guide track 56 via the sliders 68 in this context. By actuating the second motor, the rearward lid element 32 is then displaced towards the rear and is pivoted around the pivot axis defined by the slider 78 of the support arm 76 by displacing the slider 74 of the pivot arm 72 in the allocated slotted link of the guide track 56. The bows 46, 48, 50 and 52, to which the top cover 42 is fixed, are moved towards the rear by the rear lid element 32 until the end or opened position illustrated in FIGS. 4, 6 and 12 is attained. The outward-extension bows 48 and 52 are extended outward by means of the outward-extension springs 58 and 60 so that the top cover 42 forms fabric pleats defined by the bows 46, 48, 50 and 52. In the then attained opened position, the two lid elements 30 and 32 are disposed above the folding-top section 26, said lid element 30 partially covering said lid element 32 (FIG. 12).

(31) If the top opening system 20 is to be brought back to its closed position, the bows 46, 48, 50 and 52, which are fixed to the lid element 32, are pulled forward. For this purpose, the bows 48 and 52 are brought to a lowered position against the force of the outward-extension springs 58 and 60.

(32) In FIGS. 13 to 17, a vehicle construction 10 is illustrated which comprises a vehicle body 12 and is provided with a top arrangement 14 essentially corresponding to the top arrangement illustrated in FIGS. 1 to 12 but differing in the respect that it comprises a top cover 42 which is only fixed to the rear element of the two lid elements 30 and 32. The front lid element 30 is designed without fixation with regard to top cover 42. At its front edge extending in the transverse direction of the top, the rear lid element 32 moreover comprises a seal profile 80 which seals a gap between the front lid element 30 and the rear lid element 32 in a closed position, in which a top opening 18 is entirely closed. The front lid element 30 abuts against the seal profile 80 (cf. FIG. 16).

(33) The top arrangement 14 or rather the top opening system comprising the two lid elements 30 and 32 and the top cover 42 has a displacement kinematics which essentially corresponds to the displacement kinematics described in conjunction with the embodiment according to FIGS. 1 to 12. The front lid element 30 is therefore provided with a multi-joint kinematics on each of its two sides relative to a vertical longitudinal center plane of the top, is raised by means of said multi joint kinematics and can be shifted towards the rear above the rear lid element 32 and a folding-top section 26 formed by the top cover 42. The rear lid element 32 is provided with a support arm on each of its two sides relative to the vertical longitudinal center plane of the top, said support arm being guided in a corresponding guide track by means of a slider as well as being connected to a pivot arm enabling pivoting the rear lid element 32 by interacting with a slotted link fixed to the guide track so that the lid element 32 can be shifted over the folding-top section 26.

(34) With regard to the further features of the displacement kinematics for the two lid elements 30 and 32 and for the folding-top section 26 and its bows 46, 48, 50 and 52, the foregoing embodiments as well as the embodiment according to FIGS. 1 to 12 is referred to.

(35) In FIGS. 18 to 21, a vehicle construction 10 having another embodiment of a top arrangement 14 according to the invention is illustrated. The top arrangement 14 comprises a rearward hard-top element 82 forming a folding-top section which a top cutout 28 borders at the front, said top cutout 28 alternatively being able to be either opened or closed by means two displaceable lid elements 30 and 32. The two lid elements 30 and 32 and the hard-top element 82 are disposed behind one another in the longitudinal direction of the top in the closed position illustrated in FIGS. 18 and 20 and spanned by a continuous top cover 42. The lid elements 30 and 32 and the hard-top element 82 act like surface bows in this context and serve as an abutment surface for the top cover 42.

(36) The lid elements 30 and 32, which are components of a top opening system, comprise a displacement kinematics essentially corresponding to the displacement kinematics of the two lid elements of the embodiment according to FIGS. 1 and 12, for which reason their description can be foregone. Indeed the description of the embodiment according to FIGS. 1 to 12 is referred to in this context.

(37) As can be seen in FIGS. 19 and 21, the two lid elements 30 and 32 are shifted rearward over the hard-top element 82 when opening the top cutout 28, the top cover 42 being folded, which is fixed to the upper side of the rear lid element 32 in a rearward section and in a rearward section of the hard-top element 82. In contrast, in the closed position the top cover 42 is pulled taut and spans the lid elements 30 and 32 and the hard-top element 82 entirely.

(38) At its front edge extending in the transverse direction of the vehicle, the hard-top element 82 has a seal lip 84 against which the rear edge of the rear lid element 32 abuts in the closed position. At its front edge extending in the transverse direction of the top, the rear lid element 32 accordingly has a seal lip 86 on which the front lid element 30 rests with its rear edge in the closed position.
