Arrangement for raising engine hood for pedestrian safety has pyrotechnical device for driving final control element in first direction and force limiting device acting in direction opposite to first direction

摘要

The arrangement (16) has a pyrotechnical device (22) for driving a final control element in a first direction and a force limiting device acting in a direction opposite to the first direction. The force limiting device has at least one roller body (34) arranged between a ramp surface (32) and a wall that moves along the ramp surface when the ramp surface it is deflected in the second direction, thereby pressing radially outwards against the wall and plastically deforming it.
