| 摘要 |
The invention relates to a device (1a) for absorbing kinetic energy, in particular for installing in a motor vehicle, comprising a first stationary component (4a) and a second component (3a) that can be moved in relation to the first component (4a), wherein at least one of the components (3a, 4a) converts energy by plastic deformation when a certain force level is exceeded, and comprising a coupling apparatus (20), which operatively connects the first component (3a) and the second component (4a) in such a way that the two components (3a, 4a) can be moved in relation to each other only with low energy conversion when the coupling apparatus (20) is not activated and forces can be transmitted from one component (3a) to the other component (4a) when the coupling apparatus (20) is activated. According to the invention, the movable component (3a) has a deformation element (15), which initially deforms in the event of a crash, so that a movement of the movable component (3a) occurs only thereafter, wherein the coupling apparatus (20) is continuously in engagement with -the two components (3a, 4a) and thus continuously produces a first low coupling force level and, when the coupling apparatus is activated, the coupling forces are increased from the first low coupling force level to a high coupling force level and plastic deformation of at least one component (3a, 4a) occurs. |
