In this way, the risk of the fifth force directing structure on the C-pillar assembly communicating with the first force directing structure 110 on the D-pillar assembly 100 through the second force directing structure 310 on the D-pillar reinforcement assembly 300 may be reduced.

In some possible embodiments, the inboard force-guiding cavity 312 is oriented along the trend of the D-pillar reinforcement inner panel 330 and the outboard force-guiding cavity 311 is oriented along the trend of the D-pillar reinforcement outer panel 320.
