Patent number: 10558066Abstract: A vehicular sun visor includes a light shielding unit having a plurality of liquid crystal panels each of which enables a transmittance to be changed, and a sensor unit. The sensor unit includes a housing having a front wall part and a rear wall part, a pinhole formed on the front wall part, and a plurality of light receiving elements that are provided on the rear wall part and adapted to receive light passing through the pinhole. The plurality of liquid crystal panels are adapted to change a light transmittance based on light-receiving states of the plurality of light receiving elements each of which is associated with each of the liquid crystal panels.Type: GrantFiled: June 12, 2017Date of Patent: February 11, 2020Assignee: HONDA MOTOR CO., LTD.Inventor: Keita Ishizaka

Patent number: 9624956Abstract: Bulging portions elastically coming into contact with an inner peripheral surface of a fixation hole of a panel member are formed on an outer peripheral surface of a shaft portion of a waterproof clip made of an elastic material, thereby sealing a space between these surfaces by elasticity of the bulging portions to obtain a waterproof function, and firmly fixing the shaft portion to the panel member by friction force between the inner peripheral surface and the bulging portions. The clip requires no special seal member, thereby reducing the number of parts and assembly steps. Each bulging portion is formed narrower toward the front side in the insertion direction of the shaft portion, thereby easily press fitting the shaft portion into the fixation hole while improving waterproofness and airtightness by sufficiently compressing the bulging portions. The clip can surely fix an interior material to the panel member with excellent sealability.Type: GrantFiled: October 7, 2014Date of Patent: April 18, 2017Assignees: Honda Motor Co., Ltd., Nifco Inc.Inventors: Keita Ishizaka, Mamoru Ishii, Yohei Nagahori

Patent number: 9108530Abstract: A vehicle door for use on a vehicle includes a pocket having a side wall assembly that defines a space in the pocket. The side wall assembly includes an inner wall member disposed in a transverse inward direction of the vehicle. A hand grip is bendable with respect to the inner wall member by a bendable web. The hand grip has a front tooth including a support that extends through a front hole, and a locking hook that extends from the support and engages with a lower surface of a front wall of the inner wall member. A front support wall is mounted on the inner wall member for keeping the front tooth from being removed out of the front hole.Type: GrantFiled: July 31, 2013Date of Patent: August 18, 2015Assignees: TS TECH CO., LTD., HONDA MOTOR CO., LTD.Inventors: Katsuyori Yamaguchi, Keita Ishizaka, Hiroshi Sato
