5 results about "Crumple zone" patented technology

Crumple zones, crush zones, or crash zones, are a structural safety feature used in vehicles, mainly in automobiles, to increase the time over which a change in velocity (and consequently, momentum) occurs from the impact during a collision by controlled deformation; in recent years also incorporated into trains and railcars. Crumple zones are designed to increase the time over which the total force from the change in momentum is applied to an occupant, as the average force applied to the occupants is inversely related to the time over which it is applied.
