Patent number: 11192594Abstract: There are provided first and second loop-shaped structure sections which are respectively provided to extend continuously along a lower wall part, right-and-left both side wall parts, and an upper wall part of a vehicle body so as to have a loop shape in a vehicle elevational view. The first loop-shaped structure section is positioned in front of a damper support section. A lower-side part of the second loop-shaped structure section which is located at a lower level than the damper support section is formed by a part of the first loop-shaped structure section and its upper-side part is positioned in back of the damper support section. Each of these loop-shaped structure sections is formed by a closed-cross section portion where a closed-cross section is partitioned by plural members and/or a thick plate portion having a thicker plate thickness than a vehicle-body panel.Type: GrantFiled: January 3, 2020Date of Patent: December 7, 2021Assignee: MAZDA MOTOR CORPORATIONInventors: Kazunori Ishimoto, Hideaki Hoshuyama, Yukitaka Takeshita, Kenichi Sato, Itsuki Gunji

Patent number: 10967909Abstract: A side frame comprises a center pillar which includes a reinforcement provided on an outward side in a vehicle width direction and an inner panel provided on an inward side in the vehicle width direction. The reinforcement comprises upper-and-lower hinge attachment sections for attaching rear-door hinges and first-and-second recessed beads for promoting bending of the center pillar in a vehicle side collision. The hinge attachment sections are provided to be spaced apart from each other in a vertical direction. The first recessed bead is provided at a higher level than the lower hinge attachment section. The second recessed bead is provided at a lower level than the lower hinge attachment section and configured to be bent before the first recessed bead in the vehicle side collision.Type: GrantFiled: July 18, 2019Date of Patent: April 6, 2021Assignee: MAZDA MOTOR CORPORATIONInventors: Hideaki Hoshuyama, Shuang Gao, Ryota Nakayama, Akihiro Kawano, Satoshi Okumura
