Patent number: 10647283Abstract: A shock absorber formed such that at least part of an end wall of a groove rib is a fragile portion, or a shock absorber that makes a fracture behavior according to a design intent. The shock absorber has a hollow molded-body having a hollow. The hollow molded-body includes front and rear walls that are spaced from and opposed to each other and a side wall that connects the front and rear walls. The side wall is provided with a front groove rib formed by recessing the front wall and a rear groove rib formed by recessing the rear wall. A side groove wall is formed by welding together at least parts of end walls of the front groove rib and the rear groove rib.Type: GrantFiled: November 22, 2016Date of Patent: May 12, 2020Assignee: KYORAKU CO., LTD.Inventors: Takafumi Funato, Teruo Tamada, Yosuke Muroya

Patent number: 10351088Abstract: Provided is a knee bolster that is formed of a blow-molded body and can be easily and stably mounted on a mounting target. The blow-molded body has a back surface having a mounting protrusion to be inserted into a mounting hole formed in a mounting target. The blow-molded body includes a lower lock disposed so as to protrude from the back surface to under the mounting target and configured to suppress upward movement of the blow-molded body relative to the mounting target.Type: GrantFiled: March 10, 2016Date of Patent: July 16, 2019Assignee: Kyoraku Co., Ltd.Inventors: Naoto Tani, Takafumi Funato

Patent number: 9522646Abstract: Provided is a knee bolster which does not significantly increase the vehicle weight and whose plastic deformation starting load can be easily controlled to a desired value. A knee bolster becomes deformed when a load from a knee of a passenger is inputted and thus absorbs a shock applied to the knee. The knee bolster includes a low-load absorption unit having a load input surface to which the load from the knee is inputted and a high-load absorption unit disposed in a more distant position from the knee than the low-load absorption unit in an input direction of the load and having a higher plastic deformation starting load than a plastic deformation starting load of the low-load absorption unit. The low-load absorption unit and the high-load absorption unit are formed of a single hollow structure or different hollow structures.Type: GrantFiled: March 5, 2014Date of Patent: December 20, 2016Assignee: KYORAKU CO., LTD.Inventors: Teruo Tamada, Takafumi Funato
