Rear vehicle body structure

A rear vehicle body structure, the structure comprising:

• a side sill comprising a sill inner member and a sill outer member connected to each other, the side sill extending along a front to rear direction of a vehicle body at a lower portion of a side body;
• a sill rear inner member connected to a rear portion of the sill inner member along the front to rear direction of the vehicle body;
• a sill rear outer member connected to a rear portion of the sill outer member along the front to rear direction of the vehicle body and connected to the sill rear inner member along a vehicle width direction, wherein the sill rear inner member and the sill rear outer member are connected to define a first closed section;
• and
• a pillar reinforcement member connected to the sill rear outer member and disposed along a vertical direction of the vehicle body,
• wherein the sill rear outer member and the pillar reinforcement member are connected to define a second closed section, and
• wherein the first closed section and the second closed section are each partitioned and formed in a shape in which the sill rear outer member is disposed between the sill rear inner member and the pillar reinforcement member.

A vehicle comprising:

• a vehicle body comprising a pair of side bodies disposed on opposite sides of the vehicle body in a vehicle width direction;
• a pair of side sills each comprising a sill inner member and a sill outer member connected to each other, the pair of side sills being disposed on both sides of the vehicle body and extending along a front to rear direction of the vehicle body at lower portions of the pair of side bodies, respectively;
• a pair of sill rear inner members connected to rear portions of each of the sill inner members, respectively;
• a pair of sill rear outer members connected to rear portions of each of the sill outer members, respectively, and connected to each of the sill rear inner members, respectively;
• a pair of pillar reinforcement members connected to each of the sill rear outer members, respectively, the pillar reinforcement members being disposed along a vertical direction of the vehicle body;
• and
• a pair of rear wheel arch members on each side of the vehicle body, each rear wheel arch member being connected to the sill rear inner member and the sill rear outer member on a same side of the vehicle body, wherein on each side of the vehicle body:
• a rear portion of the sill rear inner member and a lower portion of the rear wheel arch member are connected through a third overlap portion overlapping each other along the vehicle width direction;
• a rear portion of the sill rear outer member and a rear portion of the pillar reinforcement member are connected through a fourth overlap portion overlapping each other along the vehicle width direction;
• and
• the third overlap portion and the fourth overlap portion are connected to each other along the vehicle width direction.
