Crumple zones, crush zones, [1] 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 a controlled deformation; in recent years, it is also incorporated into trains and railcars.
The crumple zone concept was originally invented and patented by Barényi in 1937, before he worked for Mercedes-Benz; and subsequently in a more developed form in 1952. [19] The 1953 Mercedes-Benz "Ponton" was a partial implementation of his ideas, [20] by having a strong deep platform to form a partial safety cell, patented in 1941. [19]
Crumple zones were also created. While it typically yielded positive results, it also had drawbacks. While it typically yielded positive results, it also had drawbacks. The debris field created new hazards for cars approaching the crash scene, and if cars hit pieces of the debris, it could be propelled into the spectator areas.
Safety experts have also raised questions about the truck’s apparently small “crumple zone” — the section of a car designed to absorb the impact of a collision.
Side-impact tests: these forms of accidents have a very significant likelihood of fatality, as cars do not have a significant crumple zone to absorb the impact forces before an occupant is injured. Pole-impact tests: A difficult test which places a large amount of force on a small proportion on the side of the vehicle.
The passengers were eerily silent while a flight attendant instructed them to remain in their seats. ... the very front of the plane served as a ‘crumple zone’ so that most of the energy is ...
The safety cell and crumple zones were achieved primarily by the design of the longitudinal members: these were straight in the centre of the vehicle and formed a rigid safety cage with the body panels, whereas the front and rear supports were curved, so they deformed in the event of an accident, absorbing part of the collision energy and ...
The term Malaise era refers to a period in the U.S. automotive industry from roughly the early 1970s through the early to mid 1980s, characterized by malaise: poor products and a generalized industry unease [1] — an era of profound adjustment as the U.S. automotive industry adapted to meet wholly new demands for more fuel-efficient, safe and environmentally responsible products.
