Patent ID: 7954419

Claim:
A reinforced cabin for a vehicle adapted to protect the interior of said cabin against a threat of a certain maximal force, said vehicle cabin being defined by at least a vehicle belly and side walls extending upwardly therefrom, and comprising: a vehicle floor extending between said side walls and spaced a distance L 1 from the 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 L 2 between said seat portion and said vehicle floor; at least one resistance member having a proximal end fixedly attached to said belly and a distal end adjacent said vehicle floor, and located at least partially underneath said seat portion; said belly being adapted to undergo, under said certain maximal force, when applied, a maximal upward deformation towards said floor of a distance L 3 , and the vehicle floor is formed with at least one opening adapted to slidingly receive therethrough said resistance member in order to allow the distal end thereof to assume a position elevated a distance corresponding to the distance L 3 above said vehicle floor, the arrangement being such that L 2 ≧L 3 , L 1 ≧L 3 and L 3 <L 4 , wherein L 4 is the maximal upward deformation which said belly would undergo towards said floor under said maximal force, in the absence of said at least one resistance member.
