Vehicle with impact protection unit

摘要

A vehicle has a frame enclosing the usable space of the vehicle. An extendable impact protection unit is connected to the frame. The extendable impact protection unit has an extendable member and a telescopic device for extending and retracting the extendable member relative to the frame. The extendable impact protection unit, when extended, enlarges the outer contour of the vehicle and provides a deformation zone for absorbing impact forces in order to protect the usable space. The telescopic device has at least two extendable components engaging different locations of the extendable member and having a travel stroke from a retracted position into an extended position. The at least two extendable components have an impact compensation capacity. The vehicle also includes a device for adjusting at least one of the impact compensation capacity and the travel stroke independently for each one of the at least two extendable components.
