Abstract
The present disclosure relates to a method for collision impact force reduction for a vehicle. The method comprises determining a smallest relative distance (D) between a head of a driver of the vehicle and a steering wheel assembly comprising an airbag of the vehicle, obtaining information of an imminent collision, the collision being at least partly frontal, comparing (300) the smallest relative distance (D) to a pre-defined threshold, and, when said smallest relative distance (D) is equal to or less than said pre-defined threshold, initiating a forward displacement of a driver seat of the vehicle and a retraction of the steering wheel assembly comprising an airbag, preferably a retraction along the steering column of the steering wheel assembly.

A method for collision impact force reduction for a vehicle, said method comprising a) determining a smallest relative distance (D) between a head of a driver of said vehicle and an inflated airbag of a steering wheel assembly of said vehicle, b) obtaining information of an imminent collision, said collision being at least partly frontal, c) comparing said smallest relative distance (D) to a pre-defined threshold, d) when said smallest relative distance (D) is equal to or less than said pre-defined threshold, initiating a forward displacement of a driver seat of said vehicle and a retraction of said steering wheel assembly comprising said airbag along a steering column of said steering wheel assembly.
A collision impact force reduction system for a vehicle, said system being adapted to
- determine a smallest relative distance (D) between a head of a driver of a vehicle and an inflated airbag of a steering wheel assembly of said vehicle,
- obtain information of an imminent frontal collision, said collision being at least partly frontal,
- compare said smallest relative distance (D) to a pre-defined threshold,
- when said smallest relative distance (D) is equal to or less than said pre-defined threshold, initiate a forward displacement of a driver seat of said vehicle and a retraction of said steering wheel assembly comprising said airbag, preferably a retraction along a steering column of said steering wheel assembly.
