Abstract

A motor-vehicle floor panel structure includes a front body sub-unit, a central floor sub-unit, and a rear body sub-unit. The central floor sub-unit has a front floor structure including a central longitudinal tunnel, a lateral longitudinal beams, connected to the front floor structure and to the front body sub-unit and two intermediate longitudinal beams which connect the central floor sub-unit to the front body sub-unit and which extend at intermediate areas between the lateral longitudinal beams and the central tunnel. The intermediate longitudinal beams are connected to the front floor structure and have portions extending in a cantilever fashion from the front edge of the front floor structure and which are connected to said front body sub-unit.

First claim

1 . A motor-vehicle floor panel structure, comprising:
a front body sub-unit, a central floor sub-unit, and a rear body sub-unit,
in which the central floor sub-unit comprises:
a front floor structure including a central longitudinal tunnel,
a pair of lateral longitudinal beams, connected to the front floor structure and to the front body sub-unit,
two intermediate longitudinal beams which connect the central floor sub-unit to the front body sub-unit and which extend at intermediate areas between said lateral longitudinal beams and said central tunnel,

said intermediate longitudinal beams connected to an upper surface of the front floor structure and have portions which extend in a cantilever fashion from a front edge of the front floor structure and which are connected to said front body sub-unit.

2 . A floor structure according to claim 1 , further comprising auxiliary intermediate longitudinal beams connected to the lower surface of the front floor structure and having a height of less than 0.5 times their width.

3 . A floor structure according to claim 1 , further comprising cross-member portions which extend between the central tunnel and the lateral longitudinal beams and which are engaged above said intermediate longitudinal beams.

4 . A floor structure according to claim 1 , wherein the portions of said intermediate longitudinal beams which project in a cantilever fashion from the front edge of the front floor structure are connected to each other by a cross-member structure longitudinally spaced apart from the front edge of the said front floor structure.

5 . A floor structure according to claim 1 , wherein said rear body sub-unit comprises a main panel with a recessed bottom wall defining a space for housing a spare-wheel, and that said bottom wall defines a substantially flat surface lying in a theoretical plane which is substantially tangent to a portion of said floor structure which is located substantially centrally along the longitudinal extension of said floor structure.

6 . A floor structure according to claim 4 , wherein said main panel has a peripheral portion surrounding said recessed bottom wall and having two opposite side portions connected to lower surfaces of two rear longitudinal beams forming part of said rear body sub-unit.

7 . A floor structure according to claim 2 , further comprising cross-member portions which extend between the central tunnel and the lateral longitudinal beams and which are engaged above said intermediate longitudinal beams.

8 . A floor structure according to claim 2 , wherein the portions of said intermediate longitudinal beams which project in a cantilever fashion from the front edge of the front floor structure are connected to each other by a cross-member structure longitudinally spaced apart from the front edge of the said front floor structure.

9 . A floor structure according to claim 3 , wherein the portions of said intermediate longitudinal beams which project in a cantilever fashion from the front edge of the front floor structure are connected to each other by a cross-member structure longitudinally spaced apart from the front edge of the said front floor structure.

10 . A floor structure according to claim 2 , wherein said rear body sub-unit comprises a main panel with a recessed bottom wall defining a space for housing a spare-wheel, and that said bottom wall defines a substantially flat surface lying in a theoretical plane which is substantially tangent to a portion of said floor structure which is located substantially centrally along the longitudinal extension of said floor structure.

11 . A floor structure according to claim 3 , wherein said rear body sub-unit comprises a main panel with a recessed bottom wall defining a space for housing a spare-wheel, and that said bottom wall defines a substantially flat surface lying in a theoretical plane which is substantially tangent to a portion of said floor structure which is located substantially centrally along the longitudinal extension of said floor structure.

12 . A floor structure according to claim 4 , wherein said rear body sub-unit comprises a main panel with a recessed bottom wall defining a space for housing a spare-wheel, and that said bottom wall defines a substantially flat surface lying in a theoretical plane which is substantially tangent to a portion of said floor structure which is located substantially centrally along the longitudinal extension of said floor structure.
