Abstract

Dispositivo de absorción de impactos, de aplicación en vehículos, caracterizado porque comprende una doble cámara, que está dotada de una cámara deformable (4) y de una cámara indeformable (3), configuradas para que ante un eventual impacto, la cámara deformable (4), quede inutilizada tras dicho impacto, y la cámara indeformable (3) mantiene su integridad estructural, permitiendo utilizar el dispositivo como elemento tractor, traccionando de la cámara indeformable (3), para desplazar un vehículo siniestrado. Ambas cámaras están rellenas de un componente absorbedor de energía (5) y relacionadas a través de un elemento de tracción (1, 2, 9) que permite absorber la energía de un impacto simultáneamente en las dos cámaras y permite la posterior tracción del vehículo siniestrado para su retirada del lugar del siniestro.
