The crumple zone concept was invented and patented by the Austrian Mercedes-Benz engineer Béla Barényi originally in 1937 before he worked for Mercedes-Benz and in a more developed form in 1952.
[13] The 1953 Mercedes-Benz "Ponton"[14] was a partial implementation of his ideas by having a strong deep platform to form a partial safety cell - patented in 1941.[13] The Mercedes-Benz patent number 854157, granted in 1952, describes the decisive feature of passive safety. Barényi questioned the opinion prevailing until then, that a safe car had to be rigid. He divided the car body into three sections: the rigid non-deforming passenger compartment and the crumple zones in the front and the rear. They are designed to absorb the energy of an impact (kinetic energy) by deformation during collision.[15] The first Mercedes-Benz carbody developed using this patent was the 1959 Mercedes W111 “Tail Fin” Saloon.[13] 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, the front and rear supports were curved so they deformed in the event of an accident, absorbing part of the collision energy and preventing the full force of the impact from reaching the occupants.[13][16][17][18] |
