Abstract
A roof side rail inner member and a roof side rail outer member of a roof side rail are coupled to each other in a first coupling portion. The roof side rail and a center pillar are coupled to each other in a second coupling portion. A bulkhead is coupled to the roof side rail outer member in a third coupling portion in a space within the roof side rail. The bulkhead is coupled to the roof side rail inner member in a fourth coupling portion. The roof side rail inner member and the roof side reinforcement are coupled to each other in a fifth coupling portion below the first coupling portion. The second, third, fourth, and fifth coupling portions together form a route along which impulsive force exerted to the center pillar is transmitted to the roof side reinforcement.
Claims8
A pillar upper structure comprising:
- a roof side rail extending along a length of a vehicle body on each end in a vehicle width direction of a body upper portion of a vehicle, the roof side rail comprising a roof side rail inner member disposed inward in the vehicle width direction and having an upper end portion and a roof side rail outer member disposed outward in the vehicle width direction and having an upper end portion, the upper end portion of the roof side rail inner member and the upper end portion of the roof side rail outer member being coupled with each other in a first coupling portion;
- a center pillar extending along a height of the vehicle body in each lateral side of the vehicle body, an upper end portion of the center pillar being coupled with the roof side rail outer member in a second coupling portion;
- a bulkhead disposed in a space formed by the roof side rail inner member and the roof side rail outer member adjacent to a location at which the upper end portion of the center pillar is coupled to the roof side rail outer member by the second coupling portion, the bulkhead being coupled with the roof side rail outer member in a third coupling portion and coupled with the roof side rail inner member in a fourth coupling portion;
- and
- a roof side reinforcement coupled with the roof side rail inner member in a fifth coupling portion that is below the first coupling portion,
- wherein the second coupling portion, the third coupling portion, the fourth coupling portion, and the fifth coupling portion form a route along which impulsive force exerted to the center pillar is transmitted to the roof side reinforcement.
