Patent number: 10293730Abstract: A seat reclining apparatus includes: first and second reclining lock mechanisms that operate in a locked state and an unlocked state, where the locked state prevents a seat back from tilting and the unlocked state allows the tilting; a first rotation member that rotates toward an unlocking direction integrally with the shaft body to change the first reclining lock mechanism from the locked state to the unlocked state; and a second rotation member that is operated to rotate by an operation member toward the unlocking direction to change the second reclining lock mechanism from the locked state to the unlocked state via a cable. When the operation member is operated, the second rotation member rotates from the locking position toward the unlocking direction by a predetermined amount, subsequently transmits a rotation force to the first rotation member toward the unlocking direction via an interlocking portion.Type: GrantFiled: February 28, 2018Date of Patent: May 21, 2019Assignees: SHIROKI CORPORATION, NHK SPRING CO., LTD.Inventors: Hidehiko Fujioka, Norihisa Nozue, Masaaki Nonomiya

Patent number: 6843533Abstract: A reclining apparatus (20) is provided with a fixed plate (21) having guide portions (41, 42), a shaft (30), a rotary plate (22) having an internal gear (66), slide gears (70, 71), a cam member (72) and the like. The cam member (72) has a pair of hook portions (100) engaging with a receiving portion (87) in the slide gears (70, 71). The hook portion (100) and the receiving portion (87) are formed in such a shape as to move the slide gears (70, 71) is a direction of canceling a rotational moment applied to the slide gears (70, 71) due to a backward load applied to the seat back when the cam member (72) rotates in a lock canceling direction. A supporting portion (120) preventing the slide gears (70, 71) from moving in a direction of the rotational moment is provided in an opposing portion between the cam member (72) and the slide gears (70, 71).Type: GrantFiled: June 16, 2000Date of Patent: January 18, 2005Assignee: NHK Spring Co., Ltd.Inventors: Kakuji Miyata, Akira Sasaki, Masaaki Nonomiya, Toshikazu Minagawa
