Floor structure of a motor vehicle body
View Patent ↗A floor structure of a motor vehicle body having a floor panel is provided. The floor structure comprises a seat connection portion which with respect to a front foot well portion is formed in vehicle vertical direction and a support structure provided below the floor panel with two longitudinal structures running in vehicle longitudinal direction and spaced from one another in vehicle transverse direction. Below the seat connection portion a cross member structure formed in one piece and corresponding to the total area of the seat connection portion is connected to the longitudinal structures located opposite in vehicle transverse direction.
1. A floor structure of a motor vehicle body, comprising:
a floor panel comprising a front foot well portion and a seat connection portion which with respect to the front foot well portion is formed elevated in vehicle vertical direction; and
a support structure provided below the floor panel with two longitudinal structures substantially running in vehicle longitudinal direction and in vehicle transverse direction which are spaced from one another,
wherein each longitudinal structure comprise an inner sill profile projecting to the inside in vehicle transverse direction and a side member profile connected thereto,
wherein below the seat connection portion a cross member structure formed in one piece and corresponding to the total area of the seat connection portion is connected to the longitudinal structure located opposite in vehicle transverse direction, and
wherein the cross member structure comprises a lateral connecting slope which closes the side member profile.
2. The floor structure according to claim 1 , wherein the cross member structure has a shell-like and predominantly closed areal structure.
3. The floor structure according to claim 1 , wherein the cross member structure along its entire extension in vehicle longitudinal direction is structurally connected to the longitudinal structures located opposite.
4. The floor structure according to claim 1 , wherein the connecting slope of the cross member structure adjoins a profile portion of the sill profile projecting to the inside from below.
5. The floor structure according to claim 4 , wherein the seat connection portion adjoins a profile portion of the inner sill profile projecting to the inside from the top with a lateral cheek.
6. The floor structure according to claim 5 , wherein the seat connection portion and the cross member structure located below comprise transverse profile portions corresponding with one another at least at an end alongside the vehicle, which form at least one closed hollow profile portion.
7. The floor structure according to claim 6 , wherein on a low side of the seat connection portion at least one reinforcement rail for a seat connection is arranged.
8. The floor structure according to claim 7 , wherein the seat connection portion comprises at least one elongated hole extending in vehicle transverse direction for the variable positioning of the reinforcement rail in vehicle transverse direction.
9. The floor structure according to claim 8 , wherein the reinforcement rail comprises at least one fastening element for the seat connection.
10. The floor structure according to claim 9 , wherein the cross member structure at its front end portion or rear end portion located outside in vehicle transverse direction comprise at least one corner support projecting in vehicle vertical direction for the seat connection portion.
11. The floor structure according to claim 10 , wherein the seat connection portion is formed free of a center tunnel.
12. The floor structure according to claim 10 , wherein the front foot well portion of the floor panel comprises at least one reinforcement profile extending from a center tunnel portion forward in travelling direction and obliquely to the outside.
13. A motor vehicle, comprising:
a floor panel comprising a front well portion and a seat connection portion which with respect to the front foot well portion is formed elevated in vehicle vertical direction, the seat connection portion formed free of a center tunnel; and
a support structure provided below the floor panel with two longitudinal structures substantially running in vehicle longitudinal direction and in vehicle transverse direction which are spaced from one another,
wherein each longitudinal structure comprises an inner sill profile projecting to the inside in vehicle transverse direction and a side member profile connected thereto.
wherein below the seat connection portion a cross member structure formed in one piece and corresponding to the total area of the seat connection portion is connected to the longitudinal structure located opposite in vehicle transverse direction, and
wherein the cross member structure comprises a lateral connecting slope which closes the side member profile.
14. The motor vehicle according to claim 13 , wherein the cross member structure has a shell-like and predominantly closed areal structure.
15. The motor vehicle according to claim 13 , wherein the cross member structure along its entire extension in vehicle longitudinal direction is structurally connected to the longitudinal structures located opposite.
16. The motor vehicle according to claim 13 , wherein the connecting slope of the cross member structure adjoins a profile portion of the sill profile projecting to the inside from below.
