Abstract
Official abstract text for this publication.
A vehicle body frame includes: side frames that have at least inner walls that are disposed at vehicle transverse direction inner sides and upper walls that are disposed at vehicle body vertical direction upper sides, and that are formed as closed cross-sectional structures, and that extend in a vehicle body longitudinal direction, and that are fastened and fixed to under members that are disposed at a vehicle body lower side of a floor panel; and an upper frame that is disposed further toward a vehicle transverse direction inner side than the inner walls and at a height that is lower than the upper walls, and at which an installed object is installed.
First claim

The invention claimed is: 1. A vehicle body frame comprising: side frames that have at least inner walls that are disposed at vehicle transverse direction inner sides and upper walls that are disposed at vehicle body vertical direction upper sides, and that are formed as closed cross-sectional structures, and that extend in a vehicle body longitudinal direction, and that are fastened and fixed to under members that are disposed at a vehicle body lower side of a floor panel; and an upper frame that is disposed further toward a vehicle transverse direction inner side than the inner walls and at a height that is lower than the upper walls, wherein an installed object is installed at the upper frame, and connecting members that connect the upper frame and upper portions of the inner walls, above the upper frame as seen from the vehicle body longitudinal direction, wherein: a lower frame is disposed at a lower side of the upper frame, and the upper frame, by being joined to the lower frame, forms a closed cross-sectional structure together with the lower frame that extends in a vehicle transverse direction. 2. A vehicle underfloor structure comprising: under members that extend in a vehicle body longitudinal direction and are disposed at a vehicle body lower side of a floor panel; and a vehicle body frame that has: side frames that have at least inner walls that are disposed at vehicle transverse direction inner sides and upper walls that are disposed at vehicle body vertical direction upper sides, and that are formed as closed cross-sectional structures, and that extend in the vehicle body longitudinal direction, and that are fastened and fixed to the under members, an upper frame that is disposed further toward a vehicle transverse direction inner side than the inner walls and at a height that is lower than the upper walls, wherein an installed object is installed at the upper frame, and connecting members that connect the upper frames and upper portions of the inner walls, above the upper frame as seen from the vehicle body longitudinal direction, wherein: a lower frame is disposed at a lower side of the upper frame, and the upper frame, by being joined to the lower frame, forms a closed cross-sectional structure together with the lower frame that extends in a vehicle transverse direction. 3. The vehicle underfloor structure of claim 2 , wherein energy absorbing members are disposed at vehicle transverse direction outer sides of the side frames. 4. The vehicle underfloor structure of claim 2 , wherein overhang portions, that jut-out from the side frames toward vehicle transverse direction outer sides, are fastened and fixed to the under members.
