Rigid sunroof, especially for motor vehicles

The invention relates to a rigid sliding roof, in particular for motor vehicles, with a ^: via an actuating mechanism for locking into the roof opening; raisable, via sliding and / or guide members on guide rails l ^:: ngs displaceable and festleebaren in any opening cover layers.

In a known design of such sliding roofs, the cover is supported by sliding blocks arranged on transversely directed holders on guide rails attached to the sliding roof cassette, the holders connecting the cover to the sliding blocks being formed by slotted spring steel sheet metal blanks and the fixing of the cover in any opening position takes place by tilting the sliding blocks with respect to the guide rails. By tilting the sliding blocks in relation to the guide rails, sufficient clamping force is achieved to hold the cover securely during normal driving, even when braking or accelerating heavily. The holding force for the cover that can be achieved in this way is, however, in no way sufficient to hold the cover in the set open position even in the event of, for example, an accident-related, extreme acceleration or deceleration of the vehicle.

The invention is therefore based on the object of providing a device for a rigid sliding roof of the type described in the introduction to fix the dachshund in any opening position to create which with the least possible manufacturing effort safe holding of the lid in the set opening position even under the conditions of extreme, accident-related acceleration or brake ramps Guaranteed.

In a sliding roof of the type mentioned at the outset, this object is achieved according to the invention in that ^; the fixing of the cover in any opening line is assigned at least two clamping and / or latching means, each engaging under a profile flange of the two guide rails, which can be inserted or lifted out by means of an actuating mechanism, in conjunction with correspondingly designed counter-latching and / or contact means in or on the guide rails . The profile flanges of the guide rails reaching under the clamping and / or latching means are supported in their engaged or operative position by the weight of the lid, so that the lid weight on the one hand allows a certain relief of the clamping device and on the other hand reduces the risk of unintentional disengagement of the latches. According to a special feature of the invention it is provided that the clamping and locking means are resiliently elastic in two mutually perpendicular planes and are used by means of a movement directed essentially diagonally to the profile cross-section of the guide rails, so that they are spring loaded against the undersides of the rails on the other hand, also under spring load, snap into holding latches aligned perpendicular to the guide rails. This has the advantage that the cover can be fixed in any opening position regardless of the position of the holding catches and the locking means are forcibly locked into the catches when the cover is pushed.

According to a preferred embodiment of the invention it is provided that the clamping and / or locking means by at least

In the area of its free end that interacts with the guide rail and the locking recesses assigned to it, the clamping tongue is provided with a clamping cam formed by an upwardly directed embossment and a locking lug formed by a corresponding cutout on its end face. Instead of being fastened to the inner cover shell, the clamping tongue can also be supported on a corresponding extension of the crankshaft via a corresponding bearing deflection and have a second stop cam for the crank pin of the crankshaft opposite its end cooperating with the guide rail or the retaining latches.

The cooperating with the clamping tongues guide rails are in this implementation form of the invention expediently by an angle profile, preferably a T-profile formed and each have in their vertically directed S _c handle the front end of the clamping tongue associated locking recesses on.
