According to one aspect of the present invention there is provided a reinforced cabin for a vehicle adapted 5 to protect the interior of the cabin against a threat of a certain maximal force. The vehicle cabin is defined by at least a vehicle belly and side walls extending upwardly therefrom. The cabin comprises a vehicle floor extending between the side walls and spaced a distance L1 from the 10 vehicle belly; at least one passenger seat comprising a seat portion parallel to the floor, and positioned such that there extends a space of a distance L2 between the seat portion and the vehicle floor; and at least one resistance member having a proximal end fixedly attached 15 to the belly and a distal end adjacent the vehicle floor, and located at least partially underneath the seat portion. The belly is adapted to undergo upward deformation under the certain maximal force towards the floor of a distance L3. The vehicle floor is formed with 20 at least one opening adapted to slidingly receive therethrough the resistance member in order to allow the distal end thereof to assume a position elevated a distance equal to the distance L3 above the vehicle floor. The arrangement is such that L2 > L3, L1 L3 and L3 < L4, 25 wherein L4 is the maximal upward deformation which the belly would undergo towards the floor under the maximal force, in the absence of the at least one resistance member.
