  • Patent number: 9637954
    Abstract: A door opening prevention mechanism includes a lever member rotatable relative to a base member and swingable in a vehicle inside-and-outside direction, and an urging member to bias the lever member toward a set position. The lever member is held in the set position when an outer handle is located in a door closing position when a given inertial force does not act in a vehicle outside direction during a vehicle collision, and swings in the vehicle outside direction from the set position to be moved to a locked position against an urging force of the urging member when the inertial force acts. When the lever member is in the set position, movement of a connection lever in a door opening direction is allowed. When the lever member is located in the locked position, movement of the connection lever in the door opening direction is restricted.

  • Patent number: 9163436
    Abstract: A door-opened-prevention mechanism comprises a lever member, and a biasing member biasing the lever member toward a set position. The lever member is assembled to a connection lever. The lever member is movable between the set position and a fallback position which is in a vehicle outer direction to the set position. When an inertia force, exerted on an outer handle toward the vehicle outer direction at the time of vehicle impact, is not exerted on the outer handle, the lever member is kept in the set position to enable a necessary and sufficient movement of the connection lever in a direction for opening a door, and when the inertia force is exerted on the outer handle, the lever member moves to the fallback position prior to movement of the outer handle for opening the door so as not to enable the necessary and sufficient movement of the connection lever.

  • Publication number: 20120074718
    Abstract: A door outer handle device for a vehicle includes a base member, an outer handle, a link mechanism, and a door opening prevention mechanism restricting a component member of the link mechanism from moving in a door opening direction by a predetermined inertia force. The door opening prevention mechanism includes a lever member being rotatable to a set rotation position to restrict the component member from moving in the door opening direction. The lever member is rotatable to a retracted rotation position to allow the component member to move in the door opening direction by being shifted to the retracted rotation position in an early stage of an operation of the outer handle from the door closed position to the door open position while the inertia force is not being applied. The door opening prevention mechanism further includes a biasing member biasing the lever member to the retracted rotation position.
