Abstract
An energy-absorbing apparatus for occupant protection in vehicles, has a receptacle with a magneto-rheological fluid which in the event of an impact is pressed through a flow zone determining the flow velocity. A device generating a variable magnetic field has pole faces in the flow zone, the magnetic field acting on the magneto-rheological fluid between the pole faces in order to regulate the flow velocity. The flow zone is divided into at least two flow routes by at least one partition forming two additional planar pole faces.
