Vehicle body

1. A vehicle body, comprising:

a vehicle base;

an upright central tunnel extending in a vehicle longitudinal direction and connected to said vehicle base, said upright central tunnel having longitudinally running turned-out portions, a shape of a U-profile in cross section, and a lower open tunnel region directed toward said vehicle base, said upright central tunnel further having, at said lower open tunnel region, two profiled closing parts disposed spaced apart from one another in the vehicle longitudinal direction and disposed and fastened between said longitudinally running turned-out portions and extending across a width of said upright central tunnel;

front and rear transverse seat supports for vehicle seats, said two profiled closing parts disposed in each case between said front and rear transverse seat supports, said front and rear transverse seat supports extending in each case to both sides of said upright central tunnel and connected to said vehicle base;

said two profiled closing parts being composed of extruded profiles and including a front closing part and a rear closing part, one of said two profiled closing parts having transversely running fastening webs being upper fastening webs, in a region of said transversely running fastening webs said profiled closing part has a plurality of transversely running open hollow chambers disposed one above another and adjacent to one another, said hollow chambers include outer hollow chambers and in each case one further hollow chamber being enclosed in said outer hollow chambers for providing a leadthrough for fastening screws, said further hollow chamber having an inwardly offset base and said upper fastening webs for one of a two-shear connection to said upright central tunnel or a connection to components of said vehicle body by means of said fastening screws.

2. The vehicle body according to claim 1 , wherein said one profiled closing part has formed in it, between said upper transversely running fastening webs, a depression functioning as a clearance for water lines of the vehicle body.

3. The vehicle body according to claim 1 , wherein a first of said profiled closing parts is composed of an extruded profile and a second of said profiled closing parts is composed of a ribbed cast part.

4. The vehicle body according to claim 3 , wherein said first profiled closing part formed as said extruded profile contains a plurality of hollow chambers divided by vertical webs and run in a vehicle transverse direction.

5. The vehicle body according to claim 3 ,

wherein said first profiled closing part has a plurality of hollow chambers including outer transversely running hollow chambers and one enclosed hollow chamber disposed in each of said outer transversely running hollow chambers, said enclosed hollow chamber having an inwardly offset lower base and an upper base; and

further comprising a fastening screw for a two-shear connection to said upright central tunnel and disposed in said upper base of said enclosed hollow chamber and in said inwardly offset lower base of said enclosed hollow chamber.

6. The vehicle body according to claim 5 , wherein:

a first of said outer transversely running hollow chambers has a greater width than a second of said outer transversely running hollow chambers; and

said first profiled closing part formed as said extruded profile contains a further, central hollow chamber disposed between said first and second outer transversely running hollow chambers.

7. The vehicle body according to claim 3 , wherein said second profiled closing part formed as said ribbed cast part contains a plurality of transverse webs and a plurality of transversely running vertical webs which are spaced apart from one another and are connected to each other by means of said plurality of transverse webs, said transverse webs and said transversely running vertical webs form a support structure which is open to one side.

8. The vehicle body as claimed in claims 3 , wherein:

said upright central tunnel has an inner wall; and

said second profiled closing part formed as said ribbed cast part has, proceeding from a fastening surface on said turned-out portion of said upright central tunnel, an elevated support bridge supported with a support surface bearing in each case against said inner wall of said upright central tunnel.

9. The vehicle body according to claim 3 , wherein said first profiled closing part formed as said extruded profile contains a web wall and two extruded profile parts which are disposed adjacent to one another and which have in each case two transversely running hollow chambers which are separated by said web wall.

10. The vehicle body according to claim 3 ,

further comprising fastening screws and one of welded nuts and retaining nuts; and

wherein said extruded profile and said rib cast part of said profiled closing parts are fastened at corners by means of said fastening screws to said vehicle body via one of said welded nuts and said retaining nuts.

11. The vehicle body according to claim 1 , further comprising fastening screws, said profiled closing parts can be mounted on one of said upright central tunnel and on parts of said vehicle body from an underside of a vehicle by means of said fastening screws.
