摘要

The nacelle (1) has a pivot connection (8) for attaching an upper part of the nacelle with a body of a vehicle, where the connection is placed at distance (D) from a gravity center (7) of the nacelle. A damping unit (11) connects the nacelle to the body, where the damping unit is directed to absorb a portion of energy of impact according to the direction of impact. A breakable connection (10) fixes the nacelle to the body. The connection is directed to break according to the direction and to release rotation of the pivot connection against the action of the damping unit.
