DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a device for controlling the movement of a cover for a vehicle sliding roof.
BRIEF SUMMARY OF THE INVENTION
With the invention, self-acting locking is achieved for the roof until the lifting movement thereof is ended.
Furthermore, a defined axis of rotation or defined pivotal point is positionally determined on the front edge of the cover during the angular movement when swinging outwards (lifting movement).
A raising of the front edge of the cover from the seal portion when the roof aperture is opened is achieved before the cover is shifted, and a lowering of the front edge into the seal portion is achieved after the closing movement.
A rocking lever combines the operations of cooperation during the positional determination of the cover pivotal point on the front edge of the cover, raising and lowering of the cover, and creation of the restraint from attendant movement of the roof when swinging outwards so that they are achieved with one single constructional component.
When the front edge of the cover is raised, the rear edge of the cover is slighly lowered, so that during its longitudinal displacement with respect to the roof surface of the motor vehicle the cover has a very flat angle of rise or extends substantially parallel to the roof surface.
BRIEF DESCRIPTION OF THE DRAWINGS
An example of embodiment of the invention is illustrated in the Figures. These show:
FIGS. 1 to 4: various operational positions of the device for controlling the cover movement;
FIG. 5: a cross-section through a guide track for the carriage movement;
FIG. 6: an overall view of the control device in which various cover positions and positions, in particular the two end positions, are shown; and
FIG. 7: an exploded view of the essential component parts of the example of embodiment.
DETAILED DESCRIPTION OF THE INVENTION
As is evident particularly from the exploded view of the example of embodiment in FIG. 7, the device for controlling the movement of a vehicle sliding roof cover 8 (FIG. 1-4) has a cover holder 1. In the cover holder 1 a swing-out slotted link 9 is provided into which a swing-out pin 7 on a carriage (transport carriage) 3 projects. Furthermore, a control slotted link 12 is provided on the cover holder. Into this projects a control pin 13 of a swivelling lever 2 guided in a longitudinal guide track 6 (guide rail). The control slotted link extends at approximately a right angle to the longitudinal direction and has a small curvature or a slight bend. Sliding blocks 19 are mounted on both sides of the swivelling lever 2 for guiding the swivelling lever 2 and may consist of a rubber base body. Sliding caps 24 of plastic are placed on the elastic sliding blocks 19. The elastic sliding blocks form a bearing pivot 14 (sliding bearing pivot) for the swivelling lever 2 which is slidable within the longitudinal guide track 6 (FIGS. 1-4).
The swivelling lever 2 is thus formed as a two armed lever. The first lever arm 21 has at its end a lock actuating member in the form of a locking pin 10. The second lever arm 22 possesses at its front end a lifting means designed as a rocking device in the form of rocking levers 4 disposed on both sides. The rocking levers are one-armed levers and possess a shaped part 28 which may be rounded or designed as a roller. The rocking levers cooperate with guide means 23 having the form of front guide faces, offset from the horizontal, on the guide rail 6.
The swing-out slotted link 9 and the control slotted link 12 are provided in a guide portion 25, projecting vertically downwards, of the cover holder 1 that has a horizontal mounting plate. The swing-out slotted link 9 has the substantial portion thereof extending inclinedly downwards from the front to the rear and thus determines the lifting motion (swing-out motion) of the cover 8. A receiving fork 15 is provided at the front end of the guide portion 25 to receive the front end of the swivelling lever 2. For this, a bearing pin is provided at the front end of the swivelling lever 2 t
