The invention relates to a motion absorber comprising a housing (1), a connecting member (2) that is mounted to be movable with respect to the housing and that is linked with a movable part whose motion should be absorbed, and an absorber element that absorbs the motion of the connecting member (2) in the housing (1). Conventional motion absorbers are disadvantageous in that their operability is limited at wide temperature variations. The aim of the invention is therefor to provide a motion absorber whose absorbing effect is as independent of the ambient temperature as possible. To this end, the absorber element is a two-part structure and comprises a permanent magnet (3) and an opposite pole (4). One part is arranged on the housing (1) and the other part is arranged on the connecting member. The magnetic force acting between the permanent magnet (3) and the antipole (4) absorbs the motion of the connecting member (2) in the housing (1).
A motion absorber comprising a housing (1), a connecting member (2) movably supported with respect to the housing, which connecting member can be connected to a movable part (25), the movement of which is to be absorbed, and comprising an absorber element, which absorbs the movement of the connecting member (2), wherein the absorber element is divided in two and includes a permanent magnet (3) and an opposite pole (4), and the magnetic force between the permanent magnet (3) and the opposite pole (4) absorbs the movement of the connecting member (3) in the housing (1).
The motion absorber according to one of the preceding claims, wherein a viscous liquid (8) is present at least in the area between the permanent magnet (3) and the opposite pole (4), which liquid absorbs speed-dependently the movement of the connecting member (2) in addition to the magnetic braking force.
