Patent number: 11148727Abstract: To reduce the amount of intrusion into the vehicle interior at the time of a side collision and achieve weight reduction, a vehicle side body structure includes a pillar member that partitions a side part opening of a body into a front part and a rear part, and the pillar member includes an upper member made of high-tensile steel and a lower member joined to the upper member, made of high-tensile steel, and having a rigidity lower than the upper member. The upper member has a reinforcing member made of high-tensile steel with a tensile strength higher than the upper member and the lower member and the lower half of the reinforcing member are shaped to have a lower bending rigidity against bending toward the inside in the vehicle width direction, toward the lower end of the reinforcing member.Type: GrantFiled: March 13, 2020Date of Patent: October 19, 2021Assignee: Mazda Motor CorporationInventors: Tadashi Yamazaki, Takeshi Nakamura, Toshiyuki Gendo

Patent number: 10843737Abstract: A method for manufacturing a vehicle body member from a joined sheet. The joined sheet is press formed into a vehicle body member with a predetermined shape by: welding a second sheet material to a first sheet material at a plurality of points including a first joint and a second joint separated from each other; press forming the joined sheet so that a ridge crossing an imaginary line segment connecting the first joint and the second joint is formed in a portion where the first sheet material overlaps the second sheet material; and before the joining step, forming a displacement facilitating portion, which facilitates displacement of the second sheet material relative to the first sheet material in a longitudinal direction of the imaginary line segment, in a portion corresponding to between the first joint and the second joint in the second sheet material.Type: GrantFiled: November 27, 2018Date of Patent: November 24, 2020Assignee: MAZDA MOTOR CORPORATIONInventors: Tadashi Yamazaki, Toshiyuki Gendo, Naoyuki Irie
