Vehicle roof with two movable panels

0001The invention relates to a vehicle roof with two movable panels in accordance the preamble of claim 1.

0002From DE 197 13 347 A1 an openable vehicle roof is known wherein which a front cover with its rear edge above the fixed vehicle roof hinged and the means of rear support lever on sliders in guides to both sides of a fixed rear cover plate is movable. Disadvantage of such a vehicle roof is that only the front lid in a fan-position can be pivoted, while for the rear vehicle occupant due to the fixed rear cover any draft-free ventilation or air extraction possibility consists.

0003From DE 38 02 380 A1 a vehicle roof with two covers is known, the both issuable as a spoiler cap with its trailing edge and to release a Roof opening are displaced. Such spoilers cover generally have the Disadvantage that the support of the cover in each case takes place only in the top third. Therefore, such roofs for vehicles with a large speed only limited suitability.

0004Object of the invention is to provide a vehicle roof that with stable Guiding the lid enables the adjustment very variable ventilation.

0005This object is achieved by the features of claim 1. advantageous Embodiments of the invention are specified in the subclaims.

0006In contrast to the aforementioned DE 197 13 347 A1, the invention the advantage that the rear lid also a movable lid, with pivotable trailing edge, so that also for the passengers in the rear region the passenger compartment ventilation possibilities are given. A stable Support of the front cover and a compact from moving out both cover with a release of a correspondingly large roof opening made possible in that the rear lid guides for guiding a rear having sliding member of the front cover.

0007Preferably, the rear slider of the front cover occurs only when a shift of the front cover to the back in the guide in the rear cover on.

0008For the back cover to various embodiments possibilities. The rear cover can in the manner of an externally guided sliding roof or a Spoiler roof along roof-mounted guides above a rear portion of the fixed vehicle roof to be displaced; it may on the other hand on the nature a sliding-lifting roof below the rear part of the fixed vehicle roof be displaced. In any case, its trailing edge is to set a Fan position swung.

0009Particularly preferably, the front cover is even with swiveled and / or Moved back cover with its rear sliding element in its guides displaced.

0010The front lid and the rear lid are preferably largely independent apart movable. Only when both cover in issued and partly are superposed gefahrer position, it makes sense, if from this Location out a pivoting movement is synchronous.

0011The front lid and the rear lid are advantageously in each case by a motor drive, particularly an electric motor movable. The two Actuators are preferably controlled by a common control device, the particular function of the respective position of the two covers Movement of actuators permits and other movements blocked. Thereby can blockages and damage to the mechanical effectively avoided will.

0012Hereinafter, an embodiment of a vehicle roof according to the invention explained in more detail with reference to the drawings. It shows:<dl tsize="6" compact="compact"><dt>Fig. 1</dt><dd>a schematic longitudinal section through a motor vehicle roof in the closed Position,</dd><dt>FIG. 2</dt><dd>the longitudinal section of FIG. 1 with a flared and partly by Rear verfahrenem front cover,</dd><dt>Fig. 3</dt><dd>the longitudinal section of FIG. 2 with flared rear cover and</dd><dt>Fig. 4</dt><dd>a schematic perspective view of the vehicle roof with flared, superimposed driven lids.</dd></dl>

0013In fixed vehicle roof 1 a large roof opening 12 is provided, which means two consecutively arranged lid 2 and 3, respectively closed or at least partially exposable. The front cover 2 is provided with a pivot axis 5 pivoted on front sliding elements 6, so that it with its trailing edge above the fixed vehicle roof 1 in a fan position is issuable. The Raising motion is generated by rear sliding elements 8, which are part of a mechanism are, the Acryl or support lever not shown in detail including how these are known from the aforementioned DE 197 13 347 A1. The front Sliding elements 6 and the rear sliding elements 8 are shown in Fig. 1 Closing position along schematically indicated guides 7 mounted.

0014The rear cover 3 is near its front edge by means of a pivot axis at front sliding elements 9 pivoted. By means of a push-out 10, it is issuable with its rear edge above the fixed vehicle roof. 1 At the rear cover 3 closes a rear part 4 of the fixed vehicle roof 1 to. Depending on the embodiment, the rear cover 3 is either only as a lifting roof be designed to swivel, so as to position the fan shown in Fig. 3 may take or the closed position illustrated in FIG. 1. Rear However, the cover 3 can also in the manner of a spoiler roof or externally guided formed sunroof (such as the front lid in the DE 197 13 347 A1) be it lengthwise into its raised position above the guides 13 Part 4 of the fixed vehicle roof 1 may be displaced to the rear. After all , the rear cover 3 is formed in the manner of a sliding-lifting roof be such that it in addition to the fan position shown in Fig. 3 with its rear edge lowered and under the part 4 of the fixed vehicle roof 1 is slidable.

0015The special feature of the present invention is that at the rear Lid 3 guides 11 are arranged, which for receiving the rear Sliding elements 8 of the front cover 2 with a displacement thereof by Rear serve. The inclusion of the rear sliding elements 8 in the guides 11 is independent of the position in which the rear cover 3 is. This can - as shown in Figure 2 shown -. Are in the closed position, that the roof opening 12 only in the front area by the front cover 2 is partially exposed. In the transition from FIG. 1 in the Fig. 2 have the release lever at the rear sliding member 8 placed such that the rear edge of the front cover 2 is lifted. The rear sliding elements 8 are furthermore at the joint between two covers 2 and 3 of the guide 7 in the Guide 11 converted, so that the rear end of the front cover 2 now supported by the sliding elements 8 and the guides 11 on the rear cover 3 is. The guides 11, to facilitate the entry of the sliding elements 8 at their front ends to be funnel-shaped expanded.

0016Regardless of the position of the front cover 2 can be prepared starting from the Closed position according to FIG. 1, the rear cover 3 with its rear edge into a Fan position can be exhibited, as shown in Fig. 3. This raising movement can also take place if the front lid 2 is already in the Fig. 2 has taken the open position shown. The front cover 2 may also independently of the position of the rear cover 3 to the rear be moved or forward. Thus, the front cover 2, for example, according to from the position shown in Fig. 3 opening position to its closing position be moved Fig. 1 without the rear cover 3 it from its fan position is lowered. Finally, both lids can 2 or 3 in the in Fig. 3 position shown in the package along the guides 7 and 13 in the Roof opening 12 are moved so that differently sized partial openings front and rear adjustable s ind.

0017The front lid 2 is connected via a drive cable 16 with a drive 14, which is preferably constructed as an electric motor and under the front part the fixed vehicle roof is arranged first The drive cable 16 is tension and pressure-resistant arranged in parallel to the guides 7 and 13 guide channels out. It is fixed to the rear sliding member 8 and causes the raising motion the raising and the displacement of the sliding elements 8 in the Guides 7 and 11 respectively.

0018The rear cover 3 is connected via a drive cable 17 with a drive 15, which is preferably constructed as an electric motor and under the rear part 4 the fixed vehicle roof is arranged first The drive cable 17 is tension and pressure-resistant arranged in parallel to the guides 7 and 13 guide channels out. It is fixed to the push-out mechanism 10 and causes the raising motion the raising and the displacement of the opening mechanics 10 connected to rear sliding elements 19 in the guides 13 and 7 respectively.

0019A control unit 18, which in the illustrated embodiment adjacent to the front Drive 14 is located, receives control signals from unillustrated Controls which allow the user to the desired positions of the lid 2 and 3 respectively select, as well as position signals of the respective positions Cover correspond. The controller 18 coordinates the movements of the actuators 14 and 15, such that no collisions or damage of the mechanics may occur. The control apparatus 18 may further specific depending on vehicle type exclude cover positions in which to unfavorable wind noise could adjust.

0020The guides 11 are preferably below the rear cover 3 near its Outer edges positioned so that the slide members 8 from the outside in the side whose guideways intervene. For this purpose, it is advantageous when the front Sliding member 9 of the rear cover 3 is slightly disposed further inwardly so that it is outside of the path that the slide member 8 with a displacement the front lid 2 increases towards the rear. The exhibit sliding elements 8 preferably inward and outward guide elements such as rollers or Sliding pin, of which the inwardly directed with the guides 11 on the rear cover 3 and the outwardly fixed to the roof with the guides 7 are engaged. The roof-mounted guides 7 have correspondingly at their Tops passage ways for the guide elements outward So that they can leave the guides 7 at once after fall inwardly directed guide elements into engagement with the guides 11 are.

0021Instead of using two drives 14 and 15 is also an operation the lid 2 and 3 by means of a single common drive possible. This then stands on drive cable and engageable and disengageable elements, for example, with self-coupling bolt stones, depending on the desired sequence of a Opening and closing movement of the cover 2 or singly or simultaneously with the sliders 8 and 19 in driving connection. Independence the operation of both the cover and the variety of opening options is limited in such an embodiment in favor of a cheaper solution. In a particularly economical version is also a manual adjustment of the lid may be made without the core idea of departing from the invention.
