Patent number: 9812997Abstract: In an opening control device in a vehicle door, in order to stop the door at a desired position, a control unit stops power supply to a motor, and a short circuit is made in an electric circuit between a first terminal and a second terminal of the motor. In the electric circuit, there is formed a regenerative brake circuit in which regenerative braking can be applied to rotation of the motor. When the door is positioned within a fully-open-position-adjacent range that is adjacent to a fully-open position of the door, regenerative braking is applied to normal rotation of the motor for opening the door and is not applied to reverse rotation of the motor for closing the door.Type: GrantFiled: October 6, 2014Date of Patent: November 7, 2017Assignee: Mitsui Kinzoku Act CorporationInventors: Ayahito Kojima, Yasuyuki Watanabe, Kazuhito Yokomori

Patent number: 9376038Abstract: A seat lock apparatus includes a case member having a striker entrance groove and a hook lever that is provided rotatably via a hook shaft and is movable between an opening position and a restraining position where the hook lever closes an opening in a striker entrance groove. The apparatus is configured to position the hook lever in the restraining position while positioning the striker in the striker entrance groove when a seatback is erected. The striker entrance groove is formed such that when the striker enters the striker entrance groove and abuts against the hook lever positioned in the restraining position, only a portion of the case member, which is positioned closer to a central side of the seatback than the hook lever is in an axial direction of the hook shaft, is brought into abutment with the striker.Type: GrantFiled: July 24, 2014Date of Patent: June 28, 2016Assignee: MITSUI KINZOKU ACT CORPORATIONInventors: Naoya Seto, Naoki Hanaki, Kazuhito Yokomori

Patent number: 9328540Abstract: In a vehicle, a striker engages with a latch which engages with a ratchet. A door of the vehicle is closed. A motion-transmitting path for transmitting power to the ratchet from an electric drive mechanism is provided. A release-canceling mechanism connects or cuts off the motion-transmitting path. When the ratchet is released from the latch, the door-cooperating lever cuts off the release-canceling mechanism to enable the ratchet to engage with the latch again. Hence the door is closed.Type: GrantFiled: August 26, 2013Date of Patent: May 3, 2016Assignee: MITSUI KINZOKU ACT CORPORATIONInventors: Kazuhito Yokomori, Kohei Yamashita

Patent number: 8967680Abstract: In a planetary gear mechanism of a vehicle door closer device, a planetary gear meshes with a sun gear and a ring gear. When the ring gear turns in one direction, the planetary gear orbits while it turns on its own axis. A closing lever is pivoted on the planetary gear and turns with orbiting of the planetary gear to move the latch to a full-latch position to enable the door to close. When the ring gear turns in the other direction, the planetary gear turns on its own axis and the sun gear turns to allow the ratchet to release from the latch to to enable the door to open. The planetary gear mechanism slows down a motor and a motion is transmitted to the ratchet to enable the ratchet to release from the latch. When the motor stops, the motion is disconnected to enable the ratchet to return to engagement with the latch.Type: GrantFiled: June 24, 2013Date of Patent: March 3, 2015Assignee: Mitsui Kinzoku Act CorporationInventors: Kazuhito Yokomori, Kohei Yamashita
