Abstract: A front structure of a vehicle comprises a pair of side members arranged in a longitudinal direction of the vehicle, a pair of crash boxes arranged at front ends of the side members, and a body back-up structure located at a rear end of the front portion. The front structure is adapted to give an impact response curve with deceleration versus time, when subjected to a full frontal barrier impact at 35 mph according to USNCAP. The impact response curve comprises in sequence: a first phase during which deceleration increases, a second phase forming a first peak level of the deceleration, a third phase during which the deceleration is less than during the second phase, and a fourth phase forming a second peak level of the deceleration, during which fourth phase the deceleration is greater than during the third phase.

Abstract: An inflatable, energy-absorbing device for positioning behind a deployable front surface of a vehicle includes at least one air bag. Each of the at least one air bag is made of a drop stitch material comprising at least an outer and an inner layer of fabric and an internal reinforcement in the form of one or more internal stitchings which extends/extend around the airbag between opposing surfaces of the outer and inner layers of fabric. The inflatable, energy-absorbing device is configured to, upon actuation thereof by means of a sensor system for detecting approaching or actual impacts, inflate and thereby deploy the front surface of the vehicle in the driving direction of the vehicle. A deployable soft nose structure is also disclosed. The deployable soft nose structure comprises a deployable front surface and at least one inflatable, energy-absorbing device as defined above, positioned behind deployable the front surface.
