Abstract
A vehicle pillar structure includes a reinforcement that is provided in a vehicle pillar and that includes a buckling portion and a strain reducing face portion, wherein the buckling portion serves as a starting point of buckling; and the strain reducing face portion is adjacent to the buckling portion in a lateral direction of the reinforcement and reduces strain that occurs when the buckling.
Claims12
A vehicle pillar structure comprising:
- a reinforcement that is provided in a vehicle pillar and that includes a buckling portion and a strain reducing face portion, wherein
- the buckling portion serves as a starting point of buckling;
- the strain reducing face portion is adjacent to the buckling portion in a lateral direction of the reinforcement and reduces strain that occurs when the buckling;
- a plurality of buckling portions are juxtaposed in a vertical direction of the reinforcement, and a plurality of strain reducing face portions are adjacent to the buckling portions;
- each buckling portion has a different buckling strength;
- and
- each strain reducing face portion has a different inclination an angle relative to a first face of the reinforcement in which the buckling portions are formed, and the strain reducing face portions are connected to each other.
