Abstract

The vehicle body lower structure in accordance with the present invention comprises a floor panel, a pair of right and left body side frames which extend longitudinally in the vehicle body, a cross member which bridges the body side frames, and a floor center member which extends longitudinally in the vicinity of the central section in the vehicle width direction, and is connected with the cross member. In the vehicle body lower structure, a seat reinforcing member is attached so as to be astride the cross member and the floor center member, which is also among said cross member, said floor center member and said floor. According to the present invention, the supporting rigidity of a seat is ensured even if the position of a seat fixing section is not consistent with that cross member in the longitudinal direction of the vehicle body.

Description

technical field [0001] The present invention relates to a lower body structure of an automobile, in particular to a lower body structure for improving the rigidity of seat support. Background technique [0002] In the conventional lower body structure, the seats are generally mounted on a floor which is a floor portion of the vehicle interior. However, in order to ensure the support rigidity of the seat, especially in order to ensure the holding force of the seat in the event of a vehicle collision, if it is only installed on the floor, it is usually not sufficient. Therefore, in general, the seat is stably supported on the floor panel by utilizing the strength of the body frame member joined to the floor panel below the floor panel. [0003] For example, a seat mounting member is generally provided above a cross member as a frame member, and the seat mounting member is fastened to the cross member via a bottom plate with bolts. Accordingly, the support rigidity of the sea...
