Abstract
A front pillar as a part of an upper arch structure joins an outer member and an inner member and is formed to have a closed cross-sectional structure. An upper bead and a lower bead are formed adjacent to side edge sections, each of which extends in a longitudinal direction of the inner member. The upper bead has a U-shaped cross-sectional shape. Due to the U-shaped cross section, second moment of area is increased, and thus strength of the front pillar is increased. In addition, the U-shaped cross section has a larger number of ridge lines than does a chevron cross section, and thus springback is suppressed.
Claims6
An upper arch structure of a vehicle body lateral section, comprising:
- an outer member that extends along a longitudinal direction of the upper arch structure and is located on an outer side in a lateral direction of the vehicle;
- and
- an inner member that extends along the longitudinal direction of the upper arch structure, is located on an inner side in the lateral direction of the vehicle, has side edge sections on both sides, each of which extends in the longitudinal direction and is joined to the outer member, and forms a closed cross-sectional structure with the outer member, wherein
- the inner member is formed with a bead that is adjacent to at least one of the side edge sections of the inner member, that has a U-shaped cross-sectional shape projected toward the outer member, and that extends along the side edge section.
