Abstract

An upper vehicle-body structure including: a pair of left and right roof side rails; strikers to which upper portions of rear doors are engaged; a second roof reinforcement that couples the roof side rails to each other at substantially same locations as the strikers; striker mounting members on which the strikers are mounted; and reinforcement members that overlap with the roof side rails from vehicle-width-direction outer sides at substantially same locations as the striker mounting members, in which the reinforcement members each have a lower end located on a vehicle upper side than a joining location between each of the striker mounting members and each of the roof side rails and are joined to the roof side rails overlapping with the reinforcement members in a vehicle up-down direction.

Dependent claims

An upper vehicle-body structure, comprising:

a pair of left and right roof side rails extending in a vehicle front-rear direction of a vehicle;
engaging members to which upper portions of side doors of the vehicle are engaged;
a roof reinforcement that couples the left and right roof side rails to each other in a vehicle width direction at substantially same locations as the engaging members in the vehicle front-rear direction;
mounting members that are joined to the roof side rails and the roof reinforcement and on which the engaging members are mounted;
and
reinforcement members that overlap with the roof side rails from vehicle-width-direction outer sides at substantially same locations as the mounting members in the vehicle front-rear direction,
wherein the reinforcement members each have a lower end that is located on a vehicle upper side at a location higher than a joining location between each of the mounting members and each of the roof side rails in a vertical up-down direction from a bottom of the vehicle to a top of the vehicle, and the reinforcement members are joined to the roof side rails in a manner in which the reinforcement members overlap the roof side rails and are external to the external surface of the roof side rails,
wherein when the roof reinforcement is considered to be a first roof reinforcement, the upper vehicle-body structure includes a second roof reinforcement that couples the roof side rails to each other in the vehicle width direction at locations more forward of the vehicle than the first roof reinforcement, wherein each of the reinforcement members comprises:
a reinforcement main body portion having a front end located between the first roof reinforcement and the second roof reinforcement;
and
a reinforcement front portion provided so as to extend from an upper portion of the reinforcement main body portion to a vehicle front side.

means for mounting that are joined to the roof side rails and the roof reinforcement and on which the means for engaging are mounted;
and
means for reinforcing that overlap with the roof side rails from vehicle-width-direction outer sides at substantially same locations as the means for mounting in the vehicle front-rear direction,
wherein the means for reinforcing each have a lower end that is located on a vehicle upper side at a location higher than a joining location between each of the means for mounting and each of the roof side rails in a vertical up-down direction from a bottom of the vehicle to a top of the vehicle, and the means for reinforcing are joined to the roof side rails in a manner in which the means for reinforcing overlap the roof side rails and are external to the external surface of the roof side rails,
wherein when the roof reinforcement is considered to be a first roof reinforcement, the upper vehicle-body structure includes a second roof reinforcement that couples the roof side rails to each other in the vehicle width direction at locations more forward of the vehicle than the first roof reinforcement, wherein each of the means for reinforcing comprises:
a reinforcement main body portion having a front end located between the first roof reinforcement and the second roof reinforcement;
and
a reinforcement front portion provided so as to extend from an upper portion of the reinforcement main body portion to a vehicle front side.
