Abstract

There are provided a pair of roof rails, a roof panel, a front header, a pair of front pillars, and a pair of center pillars, and a pair of front inclination roof reinforcements provided at a lower face of the roof panel. Each of the front inclination roof reinforcements is configured to extend obliquely from its front portion which is joined to the front header to its rear portion which is positioned on an outward side, in a vehicle width direction, relative to the front portion and joined to a portion located in the vicinity of a joint portion of the center pillar and the roof rail. Thereby, the torsional rigidity of a vehicle body can be properly improved, so that the maneuverability/stability of a vehicle can be improved.

First claim

What is claimed is:

1 . An upper vehicle-body structure of a vehicle, comprising:
a pair of right-and-left roof rails extending in a vehicle longitudinal direction at right-and-left both end portions of a roof portion of a vehicle body; a roof panel provided between the pair of right-and-left roof rails; a front header provided at a front portion of the roof panel in a vehicle width direction; a pair of right-and-left front pillars joined to the roof rails at upper portions thereof and extending downward; a pair of right-and-left center pillars provided in back of the front pillars, joined to the roof rails at upper portions thereof, and extending downward; and a pair of right-and-left front inclination roof reinforcements provided at a lower face of the roof panel, wherein each of said front inclination roof reinforcements is configured to extend obliquely from a front portion thereof which is joined to said front header to a rear portion thereof which is positioned on an outward side, in the vehicle width direction, relative to said front portion and joined to a portion located in the vicinity of a joint portion of said center pillar and said roof rail.

2 . The upper vehicle-body structure of the vehicle of claim 1 , further comprising a vehicle-width-direction roof reinforcement provided between said pair of roof rails at a position which overlaps with, in the vehicle longitudinal direction, an arrangement position of said center pillar and extending in the vehicle width direction, wherein the rear portion of each of said front inclination roof reinforcements is joined to said vehicle-width-direction roof reinforcement.

3 . The upper vehicle-body structure of the vehicle of claim 2 , wherein a partition member is provided inside said front header at a position which does not overlap with, in the vehicle width direction, a joint point of said front inclination roof reinforcement and the front header.

4 . The upper vehicle-body structure of the vehicle of claim 3 , further comprising:
a rear header provided at a rear portion of said roof panel in a vehicle width direction; an opening portion formed in back of said rear header; an openable member provided to cover said opening portion; and a pair of right-and-left rear inclination roof reinforcements provided at the lower face of said roof panel, wherein each of said rear inclination roof reinforcements is configured to extend obliquely from a rear portion thereof which is joined to said rear header to a front portion thereof which is positioned on the outward side, in the vehicle width direction, relative to said rear portion and joined to said roof rail.

5 . The upper vehicle-body structure of the vehicle of claim 2 , further comprising:
a rear header provided at a rear portion of said roof panel in a vehicle width direction; an opening portion formed in back of said rear header; an openable member provided to cover said opening portion; and a pair of right-and-left rear inclination roof reinforcements provided at the lower face of said roof panel, wherein each of said rear inclination roof reinforcements is configured to extend obliquely from a rear portion thereof which is joined to said rear header to a front portion thereof which is positioned on the outward side, in the vehicle width direction, relative to said rear portion and joined to said roof rail.

6 . The upper vehicle-body structure of the vehicle of claim 1 , wherein a partition member is provided inside said front header at a position which does not overlap with, in the vehicle width direction, a joint point of said front inclination roof reinforcement and the front header.

7 . The upper vehicle-body structure of the vehicle of claim 6 , further comprising:
a rear header provided at a rear portion of said roof panel in a vehicle width direction; an opening portion formed in back of said rear header; an openable member provided to cover said opening portion; and a pair of right-and-left rear inclination roof reinforcements provided at the lower face of said roof panel, wherein each of said rear inclination roof reinforcements is configured to extend obliquely from a rear portion thereof which is joined to said rear header to a front portion thereof which is positioned on the outward side, in the vehicle width direction, relative to said rear portion and joined to said roof rail.

8 . The upper vehicle-body structure of the vehicle of claim 1 , further comprising:
a rear header provided at a rear portion of said roof panel in a vehicle width direction; an opening portion formed in back of said rear header; an openable member provided to cover said opening portion; and a pair of right-and-left rear inclination roof reinforcements provided at the lower face of said roof panel, wherein each of said rear inclination roof reinforcements is configured to extend obliquely from a rear portion thereof which is joined to said rear header to a front portion thereof which is positioned on the outward side, in the vehicle width direction, relative to said rear portion and joined to said roof rail.
