Actuation device for a motor vehicle door lock

摘要

The invention relates to an actuation device for a motor vehicle door lock (1), comprising a handle (7), and a locking lever (10) which renders the handle (7) inactive when accelerating forces (a) of a predetermined magnitude occur, for example, in the event of an accident. In the normal operation, the locking lever (10) is displaced when impinged upon by the handle (7) and the handle (7) is simply rendered inactive in the locked operation.

主权项

1. An actuation device for a motor vehicle door lock moveable between an unlocked position and a locked position, the actuation device comprising:
a handle actuatable during a normal operation for unlocking the door lock; a deflection lever pivotally connected about an axis between the door lock and the handle, wherein the deflection lever pivots about the axis to move the door lock from the locked position to the unlocked position; and a locking lever having an inertia arm and a stop arm that extends from the inertia arm, the locking lever being engageable with the deflection lever, wherein in response to an acceleration force of greater magnitude than a force of the normal operation for unlocking the door lock, the stop arm is in a rest position where the stop arm rests against the deflection lever to prevent the deflection lever from pivoting, a moment of inertia of the inertia arm preventing movement of the stop arm, and wherein when the handle is actuated during the normal operation, the handle acts on the deflection lever to pivot the deflection lever to unlock the door lock and to displace the stop arm from the rest position.
