Abstract
Abstract A switch arrangement for electrically actuated window-panes of vehicles, especially motor vehicles in which the drive motor is controlled by switches arranged in the passenger space and includes window actuating switches and a safety device with a slip clutch which responds and interrupts the drive when a predetermined resistance to movement of the windowpane occurs; the slip clutch, however, is bypassed automatically when the window-actuating switch energizing the window drive motor in the window-opening direction is closed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
109 words
An arrangement for an electrically actuated windowpane of a vehicle, especially of a motor vehicle, in which a drive motor is controlled by switch means of a control means for opening and closing the windowpane, said switch means being arranged in the passenger space, and said control means including a safety means with a slip clutch means which upon occurrence of an excessively high resistance to movement of the windowpane responds and effectively interrupts the drive between the drive motor and a window-lifting means, characterized in that said control means includes further means for automatically rendering the safety means ineffective in the opening direction of a respectively actuated windowpane.
Claim 2
Dependent Claim
109 words
An arrangement for an electrically actuated windowpane of a vehicle, especially of a motor vehicle, in which a drive motor is controlled by switch means of a control means for opening and closing the windowpane, said switch means being arranged in the passenger space, and said control means including a safety means with a slip clutch means which upon occurrence of an excessively high resistance to movement of the windowpane responds and effectively interrupts the drive between the drive motor and a window-lifting means, characterized in that said control means includes further means for automatically rendering the safety means ineffective in the opening direction of a respectively actuated windowpane.
Claim 3
Dependent Claim
67 words
An arrangement according to claim 1, characterized in that said safety means includes a safety switch operable to effect a by-pass of the slip clutch means connected between the drive motor and the window-lifter means, said further means being operatively connected between a respective window-actuating switch means and the safety means for rendering the slip clutch means automatically inoperable exclusively in the opening direction of the window.
Claim 4
Dependent Claim
68 words
An arrangement according to claim 1, characterized in that the safety means includes by-pass means for rendering said slip clutch means ineffectual including a solenoid, window-actuating switch means for selectively energizing the drive motor in the window-closing and window-opening direction, and said further means being operatively connected between said window-opening switch means and said solenoid to render said by-pass means effective upon actuation of the window-opening switch means.
Claim 5
Dependent Claim
119 words
An arrangement for an electrically actuated window-pane of a vehicle, especially of a motor vehicle, comprising a drive motor for a window-lifting means of the windowpane for driving the window-lifting means in both the window opening and window closing directions, safety means including a slip clutch for interrupting the drive between the drive motor and the window-lifting means in response to an excessively high resistance to movement of the windowpane at any point throughout the entire path of movement thereof, and control means including switch means arranged in the passenger space for controlling the energization of said drive motor and further electrical means for automatically rendering the safety means ineffective in the opening direction of a respectively actuated windowpane.
Claim 6
Dependent Claim
119 words
An arrangement for an electrically actuated window-pane of a vehicle, especially of a motor vehicle, comprising a drive motor for a window-lifting means of the windowpane for driving the window-lifting means in both the window opening and window closing directions, safety means including a slip clutch for interrupting the drive between the drive motor and the window-lifting means in response to an excessively high resistance to movement of the windowpane at any point throughout the entire path of movement thereof, and control means including switch means arranged in the passenger space for controlling the energization of said drive motor and further electrical means for automatically rendering the safety means ineffective in the opening direction of a respectively actuated windowpane.
Claim 7
Dependent Claim
71 words
An arrangement according to claim 5, wherein said control means includes a safety switch for said safety means, said safety switch being operable to effect a by-pass of the slip clutch arranged between the drive motor and the window-lifter means, said further means being operatively connected between a respective window-actuating switch means and the safety means for rendering the slip clutch automatically inoperable exclusively in the opening direction of the windowpane.
Claim 8
Dependent Claim
88 words
An arrangement according to claim 4, wherein said safety means includes by-pass means for rendering said slip clutch ineffectual including a solenoid, said switch means for controlling the energization of said drive motor including a window opening switch means and a window closing switch means for selectively energizing the drive motor in the window opening and window closing directions, said further means being operatively connected between said window opening switch means and said solenoid to render said by-pass means effective upon actuation of the window opening switch means.
