Rear vehicle-body structure of vehicle

Abstract

The invention provides a rear vehicle-body structure in order to achieve smooth load distribution of the vehicle to the front of the vehicle when a rear collision occurs, and to improve the surface rigidity of a rear floor in the front-rear direction of the vehicle in order to achieve a force to be displaced in the front-rear direction of the vehicle generated by a rear seat when the vehicle travels. The rear vehicle-body structure of a vehicle comprises a rear-floor front part 40 on which a rear seat 30 is placed and which is inclined such that a front side thereof is located at a higher level than a rear side thereof, a pair of right-and-left reinforcements 51 which are configured such that their rear end portions 51r are positioned on both sides, in a vehicle width direction, of the rear-floor front part 40 and to extend obliquely forwardly-and-inwardly, in the vehicle width direction, from the rear end portions 51r, and a pair of right-and-left beads 65 which are provided on an outward side, in the vehicle width direction, of the pair of right-and-left reinforcements 51 and configured to extend obliquely forwardly-and-outwardly, in the vehicle width direction, from a vicinity of the rear end portions 51r of the reinforcements 51.

Description

technical field [0001] The present invention relates to a rear body structure of a vehicle provided with a forwardly rising floor on which a vehicle seat is mounted. Background technique [0002] When a collision object collides with a vehicle such as a car from the rear (rear side collision), in order to disperse and absorb the collision load from the rear (rear side collision load), it needs to be smoothly transmitted to the front of the vehicle. For this reason, it is necessary to set the rear body structure of the vehicle so that the force transmission path from the rear of the vehicle to the front for the transmission of the rear side collision load is as smooth as possible. [0003] For example, the technical solution disclosed in Patent Document 1 is: a left and right paired reinforcing frame is provided at the central position in the vehicle width direction. Suspension towers are connected in an inclined shape. [0004] Thus, in the rear body structure of the vehic...

Problems solved by technology

[0007] However, the technical solution of Patent Document 1 does not mention the specific form for ensuring the surface rigidity of the rear floor, such as the form of the reinforcement frame under the rear seat, and there is still room for discussion.
