Abstract
An energy-absorbing apparatus for occupant protection in vehicles has a receptacle in which a magnetorheological fluid is present, which in the event of an impact is pressed through a flow zone. The apparatus further has a device generating a variable magnetic field and which has a core which is wound with a coil. The magnetic field acts on the magnetorheological fluid in order to regulate the flow properties. The coil together with the core is arranged in the flow zone. The axis of the coil lies perpendicularly to the direction of flow of the magnetorheological fluid, and the flow zone has a sheathing formed of a magnetically conductive material.
