fig1 to 7 each show a cross section of an a - column of a vehicle body 1 of a motor vehicle . in each of fig1 to 7 , the a - column is formed of an outer shell 2 and an inner shell 3 , which are each interconnected at their marginal areas by means of adhesive connections 7 , 8 . thus the outer shell 2 and the inner shell 3 form a supporting closed profile . the inner shell 3 is made of a long fiber reinforced semifinished thermoplastic material ( organo sheet ). the outer shell 2 can also be made of a long fiber reinforced semifinished thermoplastic material or of metal , especially light metal , such as aluminum or steel , or of a plastic material . as shown in fig1 , an interior component 4 , 5 is attached to the inner shell 3 , which interior component 4 , 5 comprises a safety element 4 in the form of a stable cover made of metal or a plastic material and covering the inner shell 3 at its side facing away from the outer shell 2 , wherein foam 5 is formed between the inner shell 3 and the safety element 4 , which foam 5 serves to attach ( adhesively bond ) the safety element 4 to the inner shell 3 as well as to protect a passenger of the vehicle in the case of an accident due to the elastic and / or plastic properties of the foam 5 . a coating 6 embracing the inner shell 3 in the vicinity of the two adhesive connections 7 , 8 serves as a panel of the passenger compartment of the vehicle body 1 . the vehicle body 1 with the structure as shown in fig1 has increased rigidity , in particular with respect to torsional forces and / or flexural forces . it is also possible to provide embodiments without the safety element 4 . in fig2 , the outer shell 2 and the inner shell 3 supporting the interior component 4 , 5 — the outer shell 2 and the inner shell 3 being arched oppositely to one another — enclose a supporting structure 9 comprising a metal profile or formed pipes made of metal , in particular aluminum and / or steel . the outer shell 2 and the inner shell 3 may be attached to the supporting structure 9 in the most varied ways . according to fig3 , the inner shell 3 is formed such that it abuts on and partially encloses the supporting structure 9 . an adhesive connection 10 between the supporting structure 9 and the inner shell 3 reliably connects both parts , wherein the connection between the outer shell 2 and the inner shell 3 at their marginal areas by the adhesive connection 7 , 8 is maintained . as shown in fig4 , a strut member 11 in the form of a metal strip or a plastic strip is inserted between the inner shell 3 and outer shell 2 in order to reinforce the vehicle body , wherein the end portions of the strut member 11 are adhesively bonded to the marginal areas of the inner shell 3 as well as to the marginal areas of the outer shell 2 via respective adhesive connections 7 a , 7 b , 8 a , 8 b . the strut member 11 partially embraces the supporting structure 9 , resulting in a stabilization of the assembly . in another embodiment shown in fig5 , a dome 12 is formed at the inner shell 3 facing the supporting structure 9 and partially abutting in a positive - locking manner on the supporting structure 9 . in this abutting area the dome 12 of the inner shell 3 is connected to the supporting structure 9 via a further adhesive connection 13 . as shown in fig6 and 7 , the inner shell 3 and the outer shell 2 can be fixed to the supporting structure 9 also by means of connecting elements . according to fig6 , a dome 14 is formed or a mount is attached at the inside of the outer shell 2 . the dome 14 abuts on the supporting structure 9 , which has a through - hole 15 extending transversely to the longitudinal extension of the supporting structure 9 . a screw 16 is led through this through - hole 15 and anchored in the dome 14 of the outer shell 2 . the screw 16 can also be embodied as a rivet nut or the like . as can be seen from fig7 , there is provided a mount 17 at the inside of the inner shell 3 , wherein the mount 17 has a through - hole 18 in which a screw 19 is inserted . the screw 19 is screwed onto the hollow supporting structure 9 . the different connection techniques described in connection with fig1 to 7 offer various possible ways of manufacturing a vehicle body 1 . the inner shell 3 is made up of several parts , and in a first step the various parts of the inner shell 3 are connected to the corresponding interior components 4 , 5 . according to a possible embodiment , the outer shell 2 is subsequently screwed and / or glued to the supporting structure 9 . thereafter the multi - part inner shell 3 is connected to the outer shell 2 by means of adhesive bonding and to the supporting structure 9 by means of screws and / or by adhesive bonding . then an interior floor plate 20 is attached to this assembly of inner shell 3 , outer shell 2 and supporting structure 9 . according to an especially preferred embodiment according to fig8 , the multi - part inner shell 3 is screwed and / or glued to the supporting structure 9 . this assembly is then screwed and / or glued to the interior floor plate . further the assembly formed in this way is screwed and / or glued to the outer shell 2 , wherein a passenger compartment 22 is created as a separate assembly group . this passenger compartment 22 is screwed and glued to a chassis 21 . the chassis 21 made of metal constitutes a ( vehicle body ) frame determining in particular the wheel distances of a vehicle . passenger compartments 22 of different design can be mounted on such a chassis . another method of manufacturing the vehicle body is shown in fig9 . in the case of this method , too , the inner shell 3 is formed in several parts , wherein the various parts of the inner shell 3 are at first connected to the corresponding interior components 4 , 5 . thereafter the interior floor plate 20 is mounted on the chassis 21 . subsequently , the supporting structure 9 is attached to the interior floor plate 20 . according to a first embodiment , the next step comprises placing the outer shell 2 onto the supporting structure 9 and screwing and / or gluing it thereto . therein the outer shell 2 is made of a dyed plastic material , so that applying a topcoat to the vehicle body 1 can be dispensed with . finally , the multi - part inner shell 3 is glued to the outer shell 2 and connected to the supporting structure 9 by means of screws and / or adhesive bonding , thereby completing the vehicle body 1 . according to another especially preferred alternative embodiment , the multi - part inner shell 3 is screwed and / or glued to the supporting structure 9 and the assembly comprising the interior equipment 4 , 5 , the interior floor plate 20 and the chassis 21 . the outer shell 2 is attached to the assembly comprising the supporting structure 9 as well as the inner shell 3 , thereby completing the vehicle body 1 . in summary , the vehicle body 1 according to the invention and the motor vehicle according to the invention entail considerable advantages . in the case of the structure as described herein , the interior equipment 4 , 5 is embodied as a supporting part , thereby acting also as a supporting module in addition to its function as a lining . in spite of the fact that there are no additional parts for increasing rigidity , resulting in a weight reduction of the vehicle , the rigidity , especially the torsional rigidity and / or the flexural rigidity , of the vehicle is considerably improved . the joining and assembling process of the vehicle body 1 is essentially simplified .
