AI Technical Summary
Technical Problem
The existing front pillar design in vehicles concentrates stress at the extension part during collisions, risking damage and deterioration of collision performance, while also being costly to manufacture.
Method used
A front pillar member is designed with a divided portion and a base portion formed by bending, featuring a wider top plate and strategically positioned dividing line to distribute stress, using high-tensile steel for the base portion and avoiding beveled edges, joined by welding.
Benefits of technology
This design reduces manufacturing costs and maintains collision performance by suppressing stress concentration and preventing damage, while improving yield and safety by positioning the rear end behind the seats.

Abstract
It is desirable to reduce manufacturing costs while suppressing the deterioration of vehicle crash performance. [Solution] The front pillar member of the vehicle comprises a top plate portion, an upper side wall portion, a lower side wall portion, a front end upper side wall portion including the front end of the front pillar member, a front end lower side wall portion, and a front end top plate portion, a main body upper side wall portion, a divided portion, and a base portion. The divided portion includes the front end of the front pillar member, and the base portion is the portion of the front pillar member other than the divided portion. The dividing line forming the boundary between the divided portion and the base portion crosses the upper side wall portion at the boundary between the main body upper side wall portion and the front end upper side wall portion, or near said boundary on the main body upper side wall portion, and further extends to the front end of the top plate portion or the front end of the lower side wall portion.
