Claim 12

A body structure according to claim 10, wherein the longitudinal support means are connected with respective mounting means adjacent the means for detachably securing by flanged connections.

Claim 13

A body structure according to claim 11, wherein a gap is provided between the support wall means and the boundary wall means, into which is inserted sealing body means.

Claim 14

A body structure according to claim 12, wherein the means for detachably securing includes at least two detachable elements which are arranged positionally offset relative to one another.

Claim 15

A body structure according to claim 11, wherein a support wall means extends between the upper and lower longitudinal support means.

Claim 16

A body structure according to claim 1, wherein the lower mounting means has a box-shaped cross section.

Claim 17

A body structure according to claim 4, wherein the boundary wall means has an arcuately shaped configuration in the lower area and reinforcement means are provided between the arcuately shaped configuration and the reinforcing portion.

Claim 18

A body structure according to claim 1, wherein the bifurcated portion of the upper longitudinal support means includes two support sections arranged at a distance adjacent the respective mounting means.

Claim 19

A body structure according to claim 17, wherein at least one portion of the bifurcated portion of the upper longitudinal support means is aligned with and connected to a respective upper longitudinally extending support of the vehicle passenger cell.

Claim 20

A body structure according to claim 1, wherein each of the mounting means include bearing sleeve means adjacent the means for detachably securing.

Claim 21

A body structure according to claim 1, wherein the longitudinal support means are connected with the mounting means adjacent the means for detachably securing by flanged connections.

Claim 22

A body structure according to claim 3, wherein a gap is provided between the support wall means and the boundary well means, into which is inserted sealing body means.

Claim 23

A body structure for a motor vehicle with an end unit having a support structure formed of transverse and longitudinal support means, the end unit being retained relative to a boundary wall means of a passenger cell of the vehicle by mounting means including detachable elements, said boundary wall means separating the passenger cell and the end unit, said mounting means including several mounting means for mounting upper longitudinal support means and lower longitudinal support means of said end unit support structure proximate the boundary wall means, said upper and lower longitudinal support means being generally axially aligned with longitudinally extending supports of said passenger cell and mounted by said mounting means in a manner so as to generally form a continuation of the longitudinally extending supports of the support structure of the passenger cell, a lower mounting means of said several mounting means being connected with a threshold longitudinal support means of the passenger cell extending at a distance thereto by way of a reinforcing portion, a support section of said upper longitudinal support means being connected to a respective upper longitudinally extending support of the vehicle passenger cell, and the longitudinal support means being connected with respective mounting means within the area of the detachable elements by flanged connections.

Claim 24

A body structure for a motor vehicle with an end unit having a support structure formed of transverse and longitudinal support means, the end unit being retained relative to a boundary wall means of a passenger cell of the vehicle by mounting means including detachable elements, said boundary wall means separating the passenger cell and the end unit, said mounting means including several mounting means for mounting upper longitudinal support means and lower longitudinal support means of said end unit support structure proximate the boundary wall means, said upper and lower longitudinal support means being generally axially aligned with longitudinally extending supports of said passenger cell and mounted by said mounting means in a manner so as to generally form a continuation of the longitudinally extending supports of the support structure of the passenger cell, a lower mounting means of said several mounting means being connected with a threshold longitudinal support means of the passenger cell extending at a distance thereto by way of a reinforcing portion, a support section of said upper longitudinal support means being connected to a respective upper longitudinally extending support of the vehicle passenger cell, and the longitudinal support means being connected with respective mounting means within the area of the detachable elements by flanged connections.
