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.
