Abstract
A pedestrian protection device for a motor vehicle includes a bumper crossmember and a deformation element which is arranged on the bumper crossmember and which has a first element and a second element which are displaceable relative to each other in the event of a collision of the motor vehicle, and a mechanical locking mechanism. The locking mechanism has a movable locking element which is pretensionable or is pretensioned with a spring device and which is arranged on the first element or on the second element, and with a depression or step to which the other of the first element and the second element can be latched in a form-fitting manner. In the event of a high displacement speed which is greater than or equal to a predetermined second displacement speed, the locking mechanism prevents displacement of the first element relative to the second element by means of self-locking of the locking element. In the event of an average displacement speed which is lower than the predetermined second displacement speed and greater than a predetermined first displacement speed, the locking mechanism permits displacement of the first element and of the second element relative to each other.
