Abstract

A vehicle upper structure includes a roof side rail, a first roof R/F, and a gusset. The roof side rail extends in a vehicle front-rear direction. The first roof R/F has a first bulging portion and a first flange portion, and extends farther toward an inside of a vehicle cabin in a vehicle width direction than the roof side rail. The gusset is arranged extending between the roof side rail and an end portion of the first roof R/F in the vehicle width direction, and has a second bulging portion and a second flange portion on an inner end portion on the inside in the vehicle width direction.

First claim

What is claimed is:

1 . A vehicle upper structure comprising:
a roof side rail that extends in a vehicle front-rear direction; a roof reinforcement that includes a first bulging portion that bulges out downward in a vehicle up and down direction, and a first flange portion that protrudes in the vehicle front-rear direction from the first bulging portion, the roof reinforcement extending farther toward an inside of a vehicle cabin in a vehicle width direction than the roof side rail; and a gusset that is arranged extending between the roof side rail and an end portion of the roof reinforcement in the vehicle width direction, the gusset has, on an inner end portion on an inside in the vehicle width direction, a second bulging portion that bulges out downward in the vehicle up and down direction and a second flange portion that protrudes in the vehicle front-rear direction from the second bulging portion, the gusset being connected at an outer end portion on an outside in the vehicle width direction to the roof side rail, the gusset being such that the second bulging portion and the second flange portion are overlapped with, and fastened to, the first bulging portion and the first flange portion, respectively, from below in the vehicle up and down direction.

2 . The vehicle upper structure according to claim 1 , wherein
a first protruding portion that protrudes upward in the vehicle up and down direction from a bottom portion of the first bulging portion is formed on the roof reinforcement; and a second protruding portion that protrudes upward in the vehicle up and down direction from a bottom portion of the second bulging portion and overlaps with the first protruding portion from below in the vehicle up and down direction, is formed on the gusset.

3 . The vehicle upper structure according to claim 2 , wherein
the gusset is fastened in at least two locations to the first flange portion in the vehicle front-rear direction; and the gusset is fastened in at least two locations to the first bulging portion, with the first protruding portion located between the at least two locations in the vehicle front-rear direction.

4 . The vehicle upper structure according to claim 1 , wherein
the roof reinforcement includes a first roof reinforcement that has the first bulging portion and the first flange portion and is overlapped with the gusset from above in the vehicle up and down direction, and a second roof reinforcement that is overlapped with the first roof reinforcement from above in the vehicle up and down direction so as to form a closed cross-section with the first roof reinforcement; and the first flange portion, the second flange portion, and the second roof reinforcement are fastened together.

5 . The vehicle upper structure according to claim 4 , wherein
a roof panel is provided above the second roof reinforcement in the vehicle up and down direction, and an extended portion that extends toward the roof side rail and is supported by the roof side rail is formed on an end portion of the second roof reinforcement in the vehicle width direction; a stepped portion that makes a height of the second roof reinforcement in the vehicle up and down direction lower than a height of the extended portion in the vehicle up and down direction is formed on the extended portion; and a fastening member that fastens the first roof reinforcement, the second roof reinforcement, and the gusset together is fastened from below in the vehicle up and down direction.

6 . The vehicle upper structure according to claim 1 , wherein
a vertical wall portion that extends downward in the vehicle up and down direction from an outer end portion of a bottom portion in the vehicle width direction when viewed from the vehicle front-rear direction is formed on the gusset; and the vertical wall portion of the gusset is connected by welding to a vertical wall portion of a roof side rail inner panel, in a position that is to inside of the vertical wall portion of the roof side rail inner panel in the vehicle width direction, and lower than a center portion of the vertical wall portion of the roof side rail inner panel in the vehicle up and down direction.
