A pedestrian protection device for a motor vehicle, for example for a motor vehicle front end or a motor vehicle rear end, has a bumper crossmember (23) with a deformation element (1, 101) arranged on the outer side thereof, i.e. the side directed towards the front. In particular, the deformation element is arranged between a bumper fascia and the bumper crossmember. The deformation element has a first element (3, 203) and a second element (5, 205) which are displaceable relative to one another in the event of a collision. Furthermore, the pedestrian protection device has a locking mechanism which, in dependence on a displacement speed, and thus on a collision speed, of the motor vehicle, and while exploiting a mass inertia of a locking element (7, 207) which is arranged or mounted on the first element or the second element, is adjustable between a locked state in which a displacement of the first element relative to the second element is at least partially prevented by, in particular, positive engagement, and an unlocked state in which a displacement of the first element is allowed. |
