The discussion below is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter.
The present invention relates to an open roof construction for a vehicle having at least one opening in a fixed roof. The open roof construction includes a stationary part for attachment to the fixed roof, carrying at least two guide rails alongside the roof opening. At least one closure having a front and a rear side and being supported by an operating mechanism is guided by the guide rails. The closure is adjustable between a closed position, in which it closes the roof opening, and an open position in which it is at least partly moved out of the roof opening. The operating mechanism includes on each guide rail at least one adjustable first support member adjustably supporting the closure near its front side, and at least one adjustable second support member adjustably supporting the closure a distance behind the front side.
Such an open roof construction is described for example in EP 2 554 415 A1. In such open roof construction, the operating mechanism must be designed specifically for every type of vehicle.
In the afore-mentioned open roof construction at least one of the first and second support members includes two separate drive sources to be able to adjust the at least one of the first and second support members independently in horizontal and vertical direction. By providing at least one of the first and second support members with a separate drive source for the horizontal and vertical movements, it is possible to use the same operating mechanism for different types of vehicles or different types of roofs. Only a controller for the drive sources should be different or only the software of the controller should be changed to allow the support members to make the required horizontal and vertical movements for a particular type of vehicle or specific type of open roof construction. This means that mechanical parts of the operating mechanism could be the same in different types of roofs which makes design and manufacture less complicated.
Although the first support member(s) could be just a pivot, it is preferred to provide the first support member with at least a drive source for its adjustment in horizontal direction, but most preferable also with a drive source for adjustment in vertical direction, so that all kind of movements of the front side of the closure are possible.
If a support member is adjustable in vertical direction, it will always have its own drive source for the vertical adjustment. The vertical adjustment of the second support member is preferably completely independent of the vertical position of the first support member. However, two or more support members may have a common drive source for the horizontal adjustment so that they make the same horizontal movement. However, it is also possible to include a coupling between a support member and the drive source for the horizontal adjustment, allowing one support member to move horizontally with respect to the other. The first and/or second support members in the two guide rails may be coupled to a common drive source through one or two connecting elements.
The vertical adjustment of the support members may be accomplished by relatively simple mechanical mechanism, such as a lever mechanism, a screw jack, and/or a pin-slot mechanism. The connecting element for horizontal adjustment includes one of a belt, push-pull cable, rack and pinion and the like.
The drive source for the horizontal adjustment of a respective support member may be mounted stationary and be connected to the support member by said connecting element(s), or may move along with it and be engaged with the stationary part to drive the support member. The drive source may for example carry a pinion engaging a stationary rack.
An aspect of the invention also includes an operating mechanism for use in the open roof construction as described above.
Aspects of the invention will be elucidated hereafter with reference to the drawings showing embodiments of the open roof construction.
The drawing, and in first instance
The open roof construction includes a stationary part, such as a frame 3, and a closure element, in this case in the form of a rigid and preferably transparent panel 4, for example made of glass or of plastic material, which is movably supported by frame 3. In this embodiment, panel 4 is movable between a closed position, in which roof opening 1 is closed and panel 4 is at least substantially coplanar with fixed roof 2, and an open position, in which panel 4 occupies a rearward position, at least partially above the fixed roof 2 (or a second rigid panel, not shown), in which at least a part of opening 1 is cleared. In the embodiment shown, panel 4 is first tilted from the closed position (
An operating mechanism is provided on each longitudinal side of panel 4 for effecting the movements of panel 4. In this case, the operating mechanism is supported by guide rails 5 extending substantially parallel in longitudinal direction of the vehicle and mounted alongside the roof opening 1. The operating mechanism includes on each guide rail 5 a first or front support member 6 supporting panel 4 near its front side and a second or rear support member 7 supporting panel 4 a distance behind front support member 6. Other concepts are conceivable as well, for example one including a single or double central guide rail (splitting the opening 2 in two half openings) carrying one or two front support members 6, and two lateral guide rails carrying the two rear support members 7. Still other variations are possible.
As mentioned, panel 4 is supported by four support members 6, 7, each supporting panel 4 in a corner thereof when panel 4 is in its closed position. In this spoiler-type of roof, rear support members 7 are fixed in horizontal direction, and are adjustable in vertical direction only. The front support members 6 are adjustable in horizontal and vertical direction. For vertical adjustment of front and rear support members 6, 7 they each comprise their own vertical drive source 8 indicated by V in the drawing. Front support members 6 are adjustable in horizontal direction by means of a common horizontal drive source 9, in the embodiment of
The rear support members 7 are connected to panel 4 through a rail (not shown) such that, when front support members 6 move horizontally after rear support members 7 have lifted the rear side of panel 4 upwardly (
When the open roof construction is mounted in another vehicle having a different roof shape, the vertical movement can be changed to adapt the open roof construction to the vehicle type without it being necessary to change the mechanical parts of the open roof construction. Only the software in the controller for the horizontal and vertical drive sources 8, 9 should be changed.
A second embodiment of the open roof construction, in particular of the operating mechanism thereof is shown in
In the
The embodiment of
From the foregoing it is clear that aspects of the invention provide an open roof construction for a vehicle and an operating mechanism for use therein which make it possible to optimize movements of the closure and to use the same operating mechanism for different types of roofs, by just reprogramming the software of the controller. With the independent horizontal and vertical movements, it is possible to enable the closure to make movements that are not conceivable otherwise.
The invention is not limited to the embodiment shown in the drawing and described above which may be varied in different manners within the scope of the appended claims.
For example, it is possible to use the same front and rear support members for a so-called inslider type roof, in which the closure panel can be moved downwardly from its closed position in order to be moved rearwardly below the fixed roof. Other roof types and other closure elements, such as slats or multi panels are conceivable as well. The terms vertical and horizontal as used herein should be considered in a broad sense. It will depend on the orientation of guide rails 5 how the movement of the support members will be. Vertical means substantially perpendicular to the local orientation of the guide rail and horizontal means substantially parallel to the guide rail. The guide rails can be slightly curved so that the orientation of the support members will vary if they move along their guide rail.
