A door component has a controllable damping device and contains a magnetorheological fluid. Two connection units are movable relative to one another. One of the two connection units is connected to a support structure and the other one to a pivotable door unit. The device damps a movement of the door unit between a closed position and an open position in a controlled manner by way of a control unit. The magnetorheological damping device has a piston unit and a cylinder unit surrounding the piston unit. The piston unit divides a cylinder volume into two chambers. The piston unit is equipped with a first one-way valve. The two chambers are connected together, via an external return channel equipped with at least one controllable magnetorheological damping valve, to form a one-way circuit. When the piston unit moves in and out, the magnetorheological fluid flows through the piston unit in the same flow direction.

A door system with a deceleration mechanism may be adapted to control an opening of a door module that separates compartments of an aircraft and includes a door panel and a door frame. During the opening of the door module, the door panel performs a rotational movement 389 above a floor structure of the aircraft. The deceleration mechanism is operable in a normal operation mode and a deceleration mode and comprises a hinge, a wedge-shaped component that is rotatably attached to the hinge, and an activation device. The activation device is coupled to the wedge-shaped component and switches the deceleration mechanism from operating in the normal operation mode to operating in the deceleration mode when a difference in pressure between the compartments exceeds a predetermined threshold.

A method and an assembly for pivoting a movable component having a drive device with an electric drive motor in order to influence a pivoting of the component between a first setting and a second setting. A position sensor detects a position measure for a setting of the component and a speed parameter for a displacement speed of the component. During a displacement of the component with the speed parameter, an electrical setpoint current intensity for the electric drive motor is ascertained, and an associated setpoint voltage is set. The setpoint voltage is increased if a current intensity flowing through the drive motor is lower than the electrical setpoint current intensity, and the setpoint voltage is reduced if the current intensity flowing through the drive motor is higher than the electrical setpoint current intensity.

A door component for pivoting a movable door of a motor vehicle has a drive with an electric drive motor in order to influence a pivoting of the door between a closed setting and an open setting. A position measure for an angular setting of the door leaf and a speed parameter for an angular speed of the door leaf are detected by a position sensor. During a pivoting of the door leaf with the speed parameter, an electrical setpoint current intensity for the electric drive motor is ascertained, and an associated setpoint voltage is set. Then the current intensity flowing through the drive motor is ascertained. The setpoint voltage is increased if the current intensity is lower than the electrical setpoint current intensity, and the setpoint voltage is decreased if the current intensity is higher than the electrical setpoint current intensity.

A door component has a controllable damping device containing a magnetorheological fluid as a working fluid. Two connection units can move relative to one another. One of the two connection units can be connected to a support structure and the other of the two connection units can be connected to a moveable door unit of a vehicle in order to damp a movement of the door unit between a closed position and an open position under control of a control device. The damping device has an electrically adjustable magnetorheological damping valve which is current-less in an adjusted state of the damping valve. A damping property of the damping device is continuously adjusted as needed via an electrical adjustment of the damping valve.

A method for damping a movement of a door system of a vehicle that is equipped with a damping system having an adjustable and controllable damping action. A movement of the door system between a closed position and an open position is damped in a controlled manner. A measurement of the change in speed of the speed of movement of the door system is calculated and if the change in speed exceeds a predefined limit value, a set, gentle damping action is changed over to a greater damping action.
