  • Patent number: 7011349
    Abstract: A vehicle door handle device includes a frame equipped on a vehicle door panel and a handgrip mounted on the frame and rotatable about a rotation center portion at one end portion of the handgrip. A second end portion of the handgrip forms an operation portion linked with a door lock mechanism. The handgrip is adapted to be rotated within a predetermined angle around the rotation center portion to operate the door lock mechanism when the operation portion is pulled away from the frame. A restriction mechanism is also provided to restrict chattering and/or dislocation of the handgrip from the frame. The restriction mechanism includes a projection and a groove provided between the frame and the handgrip. The projection is slidable in the groove during rotation of the handgrip and is able to contact a boundary of the groove in the inserting direction of the handgrip.

  • Patent number: 6070923
    Abstract: An outside door handle assembly for an automobile includes a handle lever that follows the motion of an outside handle. When a transverse load in excess of a predetermined value acts upon the vehicle as the result of an impact at the side thereof, the handle lever is caused to swing in the transverse direction outwardly of the vehicle against the biasing force of a spring. As a result, an opening lever in a door lock device is placed in an inoperative state so that the door will not open accidentally during a side collision.
