A vehicle body side structure is provided. A vehicle body side structure includes a front fender, a side sill garnish, and an aerodynamic duct. The front fender has a fender recess portion below a first wheel arch portion. The side sill garnish has a second wheel arch portion that faces the fender recess portion at the outer side in the vehicle width direction at interval and faces a rear end of the first wheel arch portion. The aerodynamic duct is interposed between the second wheel arch portion and the fender recess portion. The width of the second wheel arch portion gradually decreases in the front-rear direction of the vehicle body as it extends upward from the front end portion of the side sill garnish to an upper edge.

A structural assembly for use in a motor vehicle includes a rocker and a running board. The motor vehicle includes a vehicle frame and a door. The rocker extends in a longitudinal direction of the motor vehicle. The running board is movably coupled to the vehicle frame between a deployed position and a stowed position in which an upper portion of the running board extends vertically above the rocker. The running board is configured to be positioned underneath the door and substantially flush with a lower portion of the door when the door is in a closed position and the running board is in the stowed position.

A rear portion of a vehicle body includes a front floor panel, a rear floor panel, a pair of left and right side sills, and a front cross plate. The rear floor panel has a higher upper surface height than the front floor panel. The front cross plate connects a rear portion of the front floor panel and a front wall of the rear floor panel, and an outer end portion in a vehicle width direction is coupled to the left and right side sills. The front wall of the rear floor panel has a plurality of bent corner portions having a side view shape bent in a substantially L shape. At least one of the bent corner portions constitutes a closed cross section extending along the vehicle width direction together with the front cross plate in a vertical height range of the left and right side sills.

Motor vehicle body structure (3), comprising, on each lateral side: a rocker panel beam (15) forming an internal space of the beam (15); and a longitudinal reinforcement (21) positioned in the interior space of the beam (15); the longitudinal reinforcement (21) extending from a centre pillar (9) to an A-pillar (7) and having an angled front portion (25) housed in the A-pillar (7).

An underbody structure of a vehicle includes a cross member, a side sill, and a gusset. The cross member is provided on a floor panel and extends in a vehicle width direction. The side sill is coupled to an outer end of the floor panel in the vehicle width direction and extends in a front-rear direction. The cross member and the side sill are separated in the vehicle width direction. The gusset is interposed between them. The gusset includes front and rear side walls, an upper wall, a protrusion, and front and rear flanges. Each side wall includes a lower end coupled to an outer end of the cross member in the vehicle width direction. The upper wall is coupled to an upper end of each side wall. The protrusion is provided at an outer end of the upper wall in the vehicle width direction.

A roof rail assembly for a motor vehicle having an open frame vehicle architecture includes a side air curtain fixedly coupled with an elongated hollow sport tube extending along a longitudinal axis of the motor vehicle. The sport tube comprises a two-piece multi-gage tube extending along a longitudinal length of an occupant compartment of the motor vehicle. The side airbag curtain is fixedly coupled with the sport tube, the side airbag curtain having a stowed condition and an inflated condition. An integrated seal carrier is fixedly coupled with the sport tube and extends laterally outboard of the motor vehicle, the integrated seal carrier comprising a removable roof sealing member and a removable door window seal, wherein the removable roof sealing member and a removable door window seal are independent of one another.

A reverse door ring assembly includes a door ring member of stamped metal with a generally ring shape to define an opening for a front door of a vehicle. The door ring member defines an A-pillar as a first sloping generally-upright portion extending to a roof edge and a B-pillar extending generally upright and transverse to the roof edge. The reverse door ring assembly includes an elongate member having a generally tubular shape extending along an exterior-facing side of the A-pillar of the door ring member on the door ring member. The reverse door ring assembly also includes a B-pillar outer member secured on an exterior-facing side of the B-pillar. The reverse door ring assembly also includes a front reinforcement upper-outer member mounted on an exterior-facing side of the second door ring member at a lower end of the A-pillar, together defining a Y-shaped cradle holding the A-pillar tube.
