Patent number: 8146965Abstract: A vehicle door lock device includes an active lever freely switchable between an unlock position and a lock position, a switching actuator, and a switching lever receiving drive force of the switching actuator to move a bushing. The active lever includes a first engagement piece and a second engagement piece. When the active lever is located at the unlock position, the second engagement piece engages with the first engagement piece located at a set position of the bushing to limit movement of the switching lever so that movement of the bushing is restricted within a range between an unset position and the set position. When the active lever is located at the lock position, the first engagement piece is arranged at a position avoiding engagement with the second engagement piece to allow the switching lever to move the bushing between the unset position and a double lock position.Type: GrantFiled: March 12, 2009Date of Patent: April 3, 2012Assignee: Aisin Seiki Kabushiki KaishaInventors: Ryujiro Akizuki, Takashi Nishio, Yusuke Yamada

Patent number: 8029028Abstract: A door lock device includes an electrical drive source, which pivots a drive member from a predetermined neutral position, and a return urging member, which returns the drive member to the predetermined neutral position. The drive member pushes a locking lever with a first engagement portion and moves the locking lever to a lock position when the drive member moves from the predetermined neutral portion in a first direction in a state in which the locking lever is arranged at an unlock position. The drive member allows the double lock lever to move to the second position and disengages the first engagement portion from the locking lever when subsequently returned to the predetermined neutral position. The drive member pushes the double lock lever with a second engagement portion when moved again from the predetermined neutral position in the first direction.Type: GrantFiled: September 9, 2009Date of Patent: October 4, 2011Assignee: Aisin Seiki Kabushiki KaishaInventors: Ryujiro Akizuki, Takashi Nishio, Yusuke Yamada, Sho Sannohe
