In the transverse middle area 156 the body 102 in particular, the center tunnel runs 138 the body 102 ,

A front end area 160 of the transverse center area 156 in the area of the passenger compartment 106 the body 102 is preferably used to connect the reinforcing elements 146a extending from this front end region 160 of the transverse center area 156 the passenger compartment 106 up to lateral end areas 162 of the longitudinal center region 158 the passenger compartment 106 the body 102 extend and there at the side sills 120 are arranged.

The reinforcing elements 146b extend within the longitudinal center region 158 from the side skirts 120 to the middle tunnel 138 ,

The reinforcing elements 146d extend from the lateral end portions 162 of the longitudinal center region 158 the passenger compartment 106 from the side sills 120 to the cross member 136 at one of the front end area 160 of the transverse center area 156 concerning the body longitudinal direction 116 opposite arranged rear end portion 164 of the transverse center area 156 the passenger compartment 106 ,

As 2 it can also be seen, are the reinforcing elements 146 in the illustrated embodiment partially in pairs with respect to a vertical passenger compartment central axis 166 , which is a cutting line of the body longitudinal plane 148 and the passenger compartment transverse plane 159 is located opposite each other.

In particular, the reinforcing elements 146a and 146d with respect to the vertical cabin center axis 166 arranged in pairs opposite each other.

As 2 it can be seen, is the body 102 designed so that in the longitudinal center region 158 the passenger compartment 106 the B-pillars 124 are arranged. Further, in the assembled state of the vehicle 100 in the longitudinal center region 158 the passenger compartment 106 (in 2 dashed lines shown) vehicle seats 168 arranged.

Because of that in the longitudinal middle area 158 the passenger compartment 106 the body 102 several reinforcing elements 146 ends and the B-pillars 124 in this longitudinal middle area 158 can be arranged on the vehicle seat 168 seated person in an accident of the vehicle 100 , especially in a side impact, are particularly well protected against injury.

The in the 1 to 7 illustrated embodiment of the vehicle 100 includes a body 102 , their basic structure 104 through the side skirts 120 , the cross member 136 , the A-pillars 114 and the B-pillars 124 , the C-pillars 128 , the D-pillars 134 and several cross struts 170 in the ceiling wall 112 is formed. Furthermore, plank elements (to be described later) may form part of the basic structure 104 form.

This basic structure 104 is by means of the reinforcing elements 146 reinforced, leaving the bodywork 102 is designed to be particularly stable and torsionally stiff.

To further strengthen the basic structure 104 are in the rear area 130 the body 102 Heck reinforcing elements 172 provided, which also reinforcing elements 146 the body 102 form.

In the illustrated embodiment of the vehicle 100 are two rear reinforcement elements 172 provided, which starting from which the rear ends 149 the side skirts 120 interconnecting cross member 136 in the area of the center tunnel 138 up to the wheel arches 132 the body 102 extend and thus are arranged substantially V-shaped (see in particular 4 ).

The rear reinforcement elements 172 are both on the cross member 136 , as well as at the central tunnel 138 , in particular on the longitudinal members 144 of the center tunnel 138 in the transverse middle area 156 the body 102 , arranged and preferably adjacent to each other directly. Furthermore, the rear reinforcement elements 172 on arcuate elements 174 arranged, which the rear ends 149 the side skirts 120 with the D-pillars 134 connect and the wheel arches 132 form.

The rear reinforcement elements 172 are in the vertical direction 110 top points of the respective arcuate element 174 arranged.

Also at these points are the C-pillars 128 arranged so that nodes 176 are formed, to which the C-pillars 128 to the rear reinforcement elements 172 adjoin.

The rear reinforcement elements 172 are curved, with the curvature inside 150 the rear reinforcement elements 172 one in the associated wheel arch 132 to be arranged (not shown) wheel of the vehicle 100 is facing.

By means of the rear reinforcement elements 172 , the C pillars 128 and one of the C-pillars 128 in the area of the ceiling wall 112 connecting cross strut 170 is a substantially annular closed structure 178 educated.

Another ring-shaped structure 178 is in the illustrated embodiment of the vehicle 100 through the rear ends 149 the side skirts 120 interconnecting cross member 136 and three support elements 180 educated.

The support elements 180 connect the side skirts 120 with the rear reinforcement elements 172 and the rear reinforcement elements 172 together.

Since the rear reinforcement elements 172 to the cross member 136 extend, are the two annularly closed structures 178 arranged overlapping in the illustrated embodiment. This allows a particularly high rigidity of the body 102 to be obtained (see 4 ).

In particular 3 can be seen, is also in the ceiling wall 112 at the in the 1 to 7 illustrated embodiment of the vehicle 100 a deltoid 172 from reinforcing elements 146 intended.

Furthermore, in the ceiling wall 112 a cross structure 182 formed, resulting in additional stabilization of the bodywork 102 can be contributed.

The 6 and 7 show the vehicle 100 in a planked condition.

The body 102 is here with plank elements 184 provided, which is an outer skin 186 of the vehicle 100 form.

The plank elements 184 can basically be independent of the basic structure 104 and / or the reinforcing elements 146 the body 102 made and with each other and with the bodywork 102 get connected.

It is advantageous, however, if the body 102 a self-supporting body is, in which the plank elements 184 at least partially the components of the basic structure 104 and / or the reinforcing elements 146 include.

In particular, it may be provided that the plank elements 184 are shaped so that reinforcing elements 146 by beads, depressions, bulges, ribs, etc. in the plank elements 184 are formed.

In a frontal collision of the vehicle 100 an obstacle behaves the vehicle shown 100 as follows:
Along with arrows in 2 illustrated load paths 188 becomes, for example, parallel to the body longitudinal direction 116 a force in the body 102 initiated, which first by means of the side skirts 120 and the center tunnel 138 is recorded.

The reinforcing elements 146a Then transfer part of the introduced force, so that the load is not restricted by the side skirts 120 and the center tunnel 138 must be transferred.

Along the reinforcing elements 146a . 146b . 146c and 146d This results in additional additional load paths 188 which allow an advantageous transmission of the introduced force and thus the safety of in the passenger compartment 106 increase the number of persons present.

In a (not shown) side impact of the vehicle 100 There is also an advantageous transmission of the introduced force by means of the reinforcing elements 146a . 146b . 146c and 146d , In particular, the force introduced in a side impact not only by means of the cross member 136 be recorded and forwarded.
