Abstract
A closing device for locking and unlocking a movable roof to and from a vehicle body includes a hook and a lever system. The hook is movable between a closed position to engage a vehicle body component and an opened position to disengage from the component. The lever system has a hook lever and a drive lever pivotable about respective pivot axes extending in a longitudinal direction. The hook is connected to the hook lever to move between the closed and opened positions in response to the hook lever pivoting. The lever system has a control lever with first and second end portions and a middle section. The end portions are respectively connected to the hook lever at first and second link axes extending in the longitudinal direction and adjacent to the pivot axes to couple the hook lever and the drive lever together.

A closing device for a movable roof of a vehicle, the closing device comprising:
- a hook movable between a closed position in which the hook is operable to engage a pin of a vehicle body to thereby lock the closing device to the vehicle body and an opened position in which the hook is operable to disengage from the pin to thereby unlock the closing device from the vehicle body;
- and
- a lever system having a hook lever pivotable about a first pivot axis extending in a longitudinal direction, the hook lever connected to the hook to move the hook between the closed and opened positions in response to the hook lever being pivoted about the first pivot axis;
- the lever system further having a drive lever pivotable about a second pivot axis extending in the longitudinal direction and offset from the first pivot axis;
- the lever system further having a control lever assembly having a control lever with first and second end portions and a middle section, wherein the first end portion of the control lever is rotatably connected to the hook lever at a first link axis which extends in the longitudinal direction and is adjacent to the first pivot axis and the second end portion of the control lever is rotatably connected to the drive lever at a second link axis which extends in the longitudinal direction and is adjacent to the second pivot axis to thereby couple the hook lever and the drive lever together;
- wherein the drive lever includes a support pin affixed thereon and the middle section of the control lever forms an indentation between the end portions of the control lever, wherein the support pin of the drive lever abuts against the indentation of the control lever between the end portions of the control lever when the hook is in the closed position such that the lever system assumes a position above top dead center when the hook is in the closed position.
A closing device for a movable roof of a vehicle, the closing device comprising:
- a hook movable between a closed position in which the hook is operable to engage a pin of a vehicle body to thereby lock the closing device to the vehicle body and an opened position in which the hook is operable to disengage from the pin to thereby unlock the closing device from the vehicle body;
- a lever system having a hook lever pivotable about a first pivot axis extending in a longitudinal direction, the hook lever connected to the hook to move the hook between the closed and opened positions in response to the hook lever being pivoted about the first pivot axis;
- the lever system further having a drive lever pivotable about a second pivot axis extending in the longitudinal direction and offset from the first pivot axis;
- the lever system further having a control lever assembly having a control lever with first and second end portions and a middle section, wherein the first end portion of the control lever is rotatably connected to the hook lever at a first link axis which extends in the longitudinal direction and is adjacent to the first pivot axis and the second end portion of the control lever is rotatably connected to the drive lever at a second link axis which extends in the longitudinal direction and is adjacent to the second pivot axis to thereby couple the hook lever and the drive lever together;
- and
- a leaf spring;
- wherein the hook lever has a first cam type section with a first cam track section and a second cam track section;
- wherein the drive lever has a second cam type section with a first cam track section;
- wherein when the hook is in the closed position the leaf spring engages the first cam track section of the first cam type section of the hook lever and is biased to pivot the hook lever about the first pivot axis to move the hook into the opened position;
- wherein when the hook is in the opened position the first cam track section of the second cam type section abuts against the second cam track section of the first cam type section.
