Abstract
A shading device for a vehicle roof includes at least one shading length that can be rolled up for shading a light-permeable and/or open area of the vehicle roof, a tension bow that is movably mounted in a direction of travel (V), to which the shading length-is fastened, a drive mechanism that can be operated by a drive motor to move the tension and a control unit for activating the drive motor. The shading device includes at least one opposing force element for restricting a traveling movement of the tension bow, and the control unit is designed to activate the drive motor based on an opposing force when the tension bow reaches an end position (P1, P2) defined by the stop element.
Claims19
A shading device for a vehicle roof, comprising:
- at least one shading length that can be rolled up for shading a light-permeable and/or open area of the vehicle roof,
- a tension bow that is movably mounted in a direction of travel (V), to which tension bow the shading length is fastened,
- a drive mechanism that can be operated by a drive motor, said drive mechanism being designed to move the tension bow back and forth between a first end position (P1) in which the shading length is rolled up, and a second end position (P2) in which the shading length is unrolled at least partially,
- a control unit for activating the drive motor,
- wherein the shading device comprises at least one opposing force element for restricting a traveling movement of the tension bow,
- wherein the control unit is designed to activate the drive motor based on a drive torque of the drive motor when the tension bow reaches an end position (P1, P2) defined by the opposing force element, and wherein the control unit is configured to compare a determined drive torque with a predetermined limit drive torque and to switch off the drive motor or to reverse the drive direction of the drive motor if the determined drive torque exceeds the predetermined limit drive torque.

- wherein the control unit is designed to activate the drive motor based on an opposing force and/or a drive torque of the drive motor when the tension bow reaches an end position (P1, P2) defined by the opposing force element,
- wherein the tension bow or the opposing force element include a force sensor to detect the opposing force, wherein the control unit is connected to the force sensor and configured to evaluate a detected opposing force and to compare it with a predetermined limit stop force.
