Abstract

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.
