Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
234 words
A control device for a power operated closure panel such as a sliding roof panel in an automobile roof, for example, where the movable roof panel can be opened out of its closed position in the roof opening in a first opening mode by raising its rear portion out of the roof opening, or in a second mode by lowering its rear portion out of the roof opening and retracting the movable panel under the statioNary roof portion, the device comprising in combination: a transverse bridge member under the stationary roof structure adjacent the rear portion of the movable roof panel and so arranged that it can be advanced and retracted under the stationary roof structure along horizontal guides; an electric motor and a drive connection between the latter and the bridge member; a control lever linking the rear portion of the movable panel to the bridge member, the control lever being pivotable on the bridge member so as to permit raising and lowering of the panel rear portion relative to the bridge member into and out of the roof opening in both directions; a control circuit for the electric motor which includes a stationary switch in the movement path of the control lever, the switch being so arranged that it is operated by the control member, when the movable panel reaches its closed position in alignment with the roof opening from either direction.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
110 words
A control device as defined in claim 1, wherein: the control lever is of the double lever type, having a forward portion connected to the panel rear portion, a pivot attachment on top of the bridge member, and a rearwardly extending cam arm portion; the stationary roof structure includes a cam groove inside which the far end of the cam arm portion is received, thereby controlling the raising and lowering of the panel rear portion, as the bridge member is advanced or retracted; and the switch is so positioned that it is operated by the cam arm portion of the control lever when the movable panel reaches its closed position.
Claim 4
Dependent Claim
57 words
A control device as defined in claim 2, wherein: the stationary switch includes a switching member which reaches into the area of the cam groove; and the cam arm portion of the control lever includes a cam finger with which it engages the cam groove and with which it also actuates the switching member of the switch.
