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.
A 2003 NHTSA study estimated that in vehicle to vehicle crashes, the design of minivans was 1.16 times as aggressive as cars, pickups were 1.39 times more aggressive, and SUVs were 1.71 times more aggressive than cars. When weight was included in the analysis, light trucks (including SUVs) were estimated to be 3.3 times more aggressive than ...
The terms "active" and "passive" are simple but important terms in the world of automotive safety. "Active safety" is used to refer to technology assisting in the prevention of a crash and "passive safety" to components of the vehicle (primarily airbags, seatbelts and the physical structure of the vehicle) that help to protect occupants during a crash.

The 1953 W120 "Ponton" partially implemented the concepts of crumple zones and the non-deformable passenger cell into its "three-box design" [6] by having a strong deep platform to form a partial safety cell (patented in 1941). [3] The Mercedes-Benz crumple zones patent (number 854157) granted in 1952, describes the decisive feature of passive ...
Because of technical reasons the existing Volvo S70, V70 and C70 models were instead equipped with the SIPS-BAG II. [13] [25] In 2006, [26] for the 2007 model year, the fourth generation SIPS was introduced incorporating more high strength steel, structural changes, more bracing and dual chamber sips-bags.
