Patent number: 8152197Abstract: A side airbag unit disposed in a side support of a seat capable of absorbing collision energy sufficiently during a side collision of a vehicle is described. In one example, the airbag unit comprises: a low expansion member disposed inside of a front skin of the seat, wherein one end of the low expansion member is attached to the inside of the front skin in the vicinity of a fragile part of the seat and the other end of the low expansion member is attached to the seatback frame through a slit. The low expansion member inhibits the front skin from expanding due to the inflation of the airbag, and a cushion pad located outside of the slit in the vehicle width direction and inside of the fragile part in the vehicle width direction is moved outward and frontward by the inflation of the airbag in a vehicle collision.Type: GrantFiled: November 19, 2009Date of Patent: April 10, 2012Assignee: Mazda Motor CorporationInventors: Seigo Taguchi, Kazuya Fukutani, Hideharu Saiki, Nobuo Inoue

Patent number: 7891704Abstract: A side airbag device provided at a seat back of a seat, comprises an airbag including a chest-abdomen protection portion to protect a chest and abdomen of an occupant seated and a waist protection portion to protect a waist of the occupant, and an inflator to supply gas to the airbag for an inflation at a vehicle side crash or a vehicle turnover, wherein the portions are partitioned by a partition portion that at least extends substantially rearward from an front edge of the airbag, and a recess is provided at an upper portion of the chest-abdomen protection portion. Accordingly, a whole part of side body including the chest, abdomen and waist can be properly protected regardless of the body size of the occupant, even for the occupant having the relatively small body size.Type: GrantFiled: June 12, 2007Date of Patent: February 22, 2011Assignee: Mazda Motor CorporationInventors: Seigo Taguchi, Naoki Kaneko, Masaki Motoki, Kazuya Fukutani

Patent number: 7520557Abstract: A pin having an enlarged head is fixed to a lower end portion of a sliding rear side door. The pin is disposed at a point corresponding to a door slide opening formed in a side sill, and the enlarged head of the pin is goes into a box member incorporated in the side sill through the door slide opening when the sliding rear side door is closed. A lower rail having a downward-opening U-shaped cross section is welded to a top plate portion of the box member. A lower roller unit fixed to the sliding rear side door fits into the lower rail, whereby the lower rail guides the sliding rear side door during opening and closing operation thereof. A vertical wall portion of the box member is welded to a first reinforcement member which passes generally vertically through the side sill.Type: GrantFiled: June 22, 2005Date of Patent: April 21, 2009Assignee: Mazda Motor CorporationInventors: Motoki Yoshida, Takashi Niseki, Kazuya Fukutani, Katsuhito Kouno
