Patent number: 11440499Abstract: A side airbag device includes an inflator; and a bag-shaped airbag inflatable and deployable in response to a gas upon activation of the inflator. The airbag includes a torso protection portion inflatable and deployable in a space beside a torso of the occupant, a support portion provided on a console box side of the torso protection portion and configured to be pushed onto a top surface of the console box in an inflated and deployed state, and a hip protection portion inflatable and deployable between a hip of the occupant and a lateral portion of the console box. The support portion and the hip protection portion are defined by a continuous chamber. The inflator is positioned from above to below the support portion in a side view of the vehicle. The airbag is mounted on a lateral portion of the vehicle seat via the inflator.Type: GrantFiled: March 25, 2021Date of Patent: September 13, 2022Assignees: MAZDA MOTOR CORPORATION, ASHIMORI INDUSTRY CO., LTD.Inventors: Taei Shibahara, Toshihiro Takebayashi, Yuichi Sugimura, Motoharu Hirata, Hidetaka Azuma, Yuta Minami, Yoshitaka Okagami, Kazuya Hashimoto

Patent number: 11299211Abstract: A lower vehicle-body structure of an electric vehicle to increase resistance to lateral collision and also improve front-end collision load transfer performance of a tunnel. The lower vehicle-body structure of an electric vehicle includes a floor having a tunnel formed in a front part at a middle in a vehicle-width direction; and a floor cross member spanning, above the floor, between side sills disposed on opposite sides of the floor. Also, a rear end of the tunnel is located directly in front of the floor cross member, and reinforcing brackets are provided extending from the tunnel toward an upper end of the floor cross member and connected to the upper end of the floor cross member.Type: GrantFiled: March 16, 2020Date of Patent: April 12, 2022Assignee: MAZDA MOTOR CORPORATIONInventors: Yamato Matsuda, Nobuyuki Nakayama, Morihide Yamada, Katsuhito Kouno, Toshihiro Takebayashi

Patent number: 11192588Abstract: A lower vehicle-body structure of an electric vehicle includes a bending facilitating portion located outward of a bent portion of a kick-up and bends as a breakage starter in a lateral collision, earlier than the bent portion, to reduce the amount of projection from the bending facilitating portion toward an outer side and reduce the likelihood of interference with a battery. Each of left and right side portions in a vehicle width direction of a kick-up is bent downward from a position inward of a rear side frame toward a side sill and connected to the side sill. A bending facilitating portion that facilitates bending under a lateral-collision load is formed outward of a bent portion of the kick-up and an outer side portion of the battery, and either inward of an inner end of the rear side frame or at substantially the same position as the inner end.Type: GrantFiled: March 17, 2020Date of Patent: December 7, 2021Assignee: MAZDA MOTOR CORPORATIONInventors: Harumitsu Kubota, Nobuyuki Nakayama, Katsuhito Kouno, Ryohei Nakagiri, Toshihiro Takebayashi

Patent number: 11091016Abstract: There are provided a pair of side sills, a floor panel, a pair of floor frames, a battery unit provided between the pair of floor frames, a first cross member interconnecting the pair of side sills, and a seat bracket. The seat bracket comprises a protrusion portion which partially covers an upper wall portion of the first side portion and is upwardly spaced apart from the upper wall portion of the first cross member, and the bead portions and the opening portion (low-rigidity portion) are formed at a part of the upper wall portion of the first cross member which is located at a position corresponding to the protrusion portion.Type: GrantFiled: January 3, 2020Date of Patent: August 17, 2021Assignee: MAZDA MOTOR CORPORATIONInventors: Yamato Matsuda, Nobuyuki Nakayama, Katsuhito Kouno, Toshihiro Takebayashi, Toshiyuki Koga

Patent number: 11014613Abstract: A side body vehicle structure is disclosed that has a pair of left and right side sills and opposite swing type side doors. The side sills may have an upper flange portion facing the rear door in the vehicle width direction which functions as a rear door facing part, and the upper flange portion of a more forward part of the vehicle than the rear door facing part may function as a front door facing part. The rear door facing part may be formed in a shape having a length in the vehicle vertical direction longer than a length in a vehicle vertical direction of the front door facing part. In a vertical cross section along the vehicle width direction, a gusset member may form a closed cross section with the side sill inner member, and an upper end thereof may be joined to the rear door facing part.Type: GrantFiled: May 1, 2019Date of Patent: May 25, 2021Assignee: Mazda Motor CorporationInventors: Shuji Muraoka, Yamato Matsuda, Toshihiro Takebayashi, Toshiyuki Koga, Kazuhisa Hatano, Morihide Yamada
