Patent number: 7934771Abstract: An armrest frame (5A) bends at a hinge groove (5A2), which serves as a weak portion, when an impact load is applied to the armrest frame (5A) in an armrest (5) following a side impact with another vehicle. As a result, the armrest (5) is allowed to move toward the inside, in the vehicle width direction, during a side impact with another vehicle, thus ensuring the movement of a seated individual toward the inside, in the vehicle width direction. The vehicle armrest (5) also provides the same sense of stability as an armrest as a conventional armrest during normal use at times other than when there is a side impact with another vehicle.Type: GrantFiled: May 3, 2006Date of Patent: May 3, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventors: Koji Tamakoshi, Kazuhiro Seki

Patent number: 6457741Abstract: An air bag, formed by sewing two basic fabrics at a sewing portion, is accommodated within a module case in a state in which the air bag has been fixed to a holder of an inflater at rear-side base portions and folded up into a bellows-like shape at a front-side foldable portions. The base portion of the left basic fabric, which is remote from a center pillar and a front door of a vehicle, has a section between two points b and c, which defines a surplus section. When the foldable portions of the air bag are expanded, the foldable portions can be moved toward an inner surface of a side of the vehicle body by the surplus section b and c and hence, the air bag can be deployed obliquely forwardly to reliably penetrate into a space between the center pillar, as well as the front door, and an occupant.Type: GrantFiled: August 12, 1998Date of Patent: October 1, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kazuhiro Seki, Takashi Aoki, Hiroyuki Maeda, Takashi Honda

Patent number: 6269669Abstract: Improvement in a method of surface-treating a back plate for friction material by blasting slurry containing particles made of plastic material through high pressure air to obtain desired surface roughness constantly for a long period of time. In the present method, no alumina grinding particle but particles made of stainless steel or titanium are fed into slurry, and the slurry is blasted through high pressure air to surface-treat the back plates. Stainless steel or the like strike works to make the surface thereof rough, which does not cause the stainless steel particles or titanium particles to be broken, unlike the grinding particles, so that the amount of sludge generated is reduced, resulting in longer life of the slurry.Type: GrantFiled: March 25, 1999Date of Patent: August 7, 2001Assignees: Nisshinbo Industries, Inc., Macoho Co., Ltd.Inventors: Tohru Matsubara, Kazuhiro Seki
