DOOR HANDLE DEVICE FOR VEHICLE

摘要

A door handle device for a vehicle includes a door opening prevention mechanism that is provided with an inertia lever being rotatably supported at a base frame, an inertia body being mounted to the inertia lever, and an elastic member elastically biasing the inertia lever toward an initial position where the movement of a link mechanism is not restricted by the inertia lever. The inertia lever includes a center of gravity of the inertia lever being set at a same position as a position of a center of gravity of the outside handle in an extending direction of the outside handle, the center of gravity of the inertia lever being set at a same position as a position of the center of gravity of the outside handle in vehicle upper-lower directions, or being set at a lower position relative to the center of gravity of the outside handle.

1. A door handle device for a vehicle comprising:
a base frame being configured to be attached to a door outer panel of a vehicle door; an outside handle being mounted on the base frame so as to be oscillated between a door closed position and a door opened position, the outside handle extending along an outer surface of a vehicle body; a link mechanism converting a movement of the outside handle in a door opening direction, the movement oscillating from the door closed position to the door opened position, into a movement releasing a retention of the vehicle door in a closed state; and a door opening prevention mechanism preventing the vehicle door from opening by restricting a movement of the link mechanism and by preventing the movement releasing the retention of the vehicle door in the closed state when the vehicle receives an impact; wherein the door opening prevention mechanism includes an inertia lever being rotatably supported at the base frame; an inertia body being mounted to the inertia lever; and an elastic member elastically biasing the inertia lever toward an initial position where the movement of the link mechanism is not restricted by the inertia lever;the inertia lever is retained at the initial position in response to an elastic biasing force of the elastic member in a case where the inertia lever is not applied with an inertia force applied toward an outer side of the vehicle when the vehicle receives an impact;the inertia lever rotates from the initial position to a restriction position where the inertia lever restricts the movement of the link mechanism against the elastic biasing force of the elastic member by using an inertia mass of the inertia body in a case where the inertia lever is applied with the inertia force applied toward the outer side of the vehicle when the vehicle receives an impact and in a case where the inertia force is greater than the elastic biasing force of the elastic member; andthe inertia lever includes a center of gravity of the inertia lever being set at a same position as a position of a center of gravity of the outside handle in the extending direction of the outside handle, the center of gravity of the inertia lever being set at a same position as a position of the center of gravity of the outside handle in vehicle upper-lower directions, or being set at a lower position relative to the center of gravity of the outside handle.
