A door component has a damper device with two connection units that can be moved relative to each other for damping a door movement of a door of a vehicle. The damper device contains a magnetorheological fluid, as an operating fluid, and a cylinder unit having a first chamber and a second chamber. The two chambers are separated from each other by a piston which is provided with a damping valve. The damper device has a connection which is constructed for coupling to a drive. The damper device can be moved in an active manner at least from a first position into a second position by the drive which is coupled via the connection.

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.

The present approach relates to a door moving device (110). The door moving device (115) comprises at least a force providing device (200), a drive device (205), and a brake device (210). The force providing device (200) is configured to provide the force for controlling a movement of the door (110). The drive device (205) is configured to generate a drive torque for driving the force providing device (200). The brake device (210) can be actuated electrically, and is configured to generate a braking torque when not provided with electricity for braking the force providing device (200) for the door (110).

A door component has a controllable damper device that contains a magnetorheological fluid as a working fluid. Two connection units of the damper device can be moved relative to each other. One of the two connection units can be connected to a support structure, and the other connection unit can be connected to a pivotal door device in order to damp a movement of the door device between a closed position and an open position in a controlled manner. The magnetorheological damper device has a piston unit and a cylinder unit which surrounds the piston unit. The piston unit divides a cylinder volume into two chambers. The piston unit has a first piston rod, which extends through the first chamber, and a second piston rod, which extends through the second chamber.

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 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.

The damping device has an electrically adjustable magnetorheological damping valve which is current-less in its adjusted state. A damping property of the damping device is continuously adjusted as needed via an electrical adjustment of the damping valve.

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.
