Patent number: 8366176Abstract: In order to avoid a vehicle door hitting the ceiling or wall when the door opens, it is necessary to provide an open-limiting device for holding the door at any open angle. The door is opened with a gear in the open-limiting device. In the open-limiting device for a vehicle door, a ratchet engages with or disengage from the gear by an electric actuator, so that the door is held at any open angle. When the ratchet engages with the gear, the ratchet is capable of disengaging from the gear only if the door is closed, but the ratchet remains in engagement with the gear if the door is opened. So the door can be closed manually by a small force.Type: GrantFiled: June 29, 2010Date of Patent: February 5, 2013Assignee: Mitsui Kinzoku Act CorporationInventor: Makoto Kaburaki
