Hood latch assembly for vehicle and method of actuating the same

A method of actuating a hood latch assembly for a vehicle, comprising:

• popping up a hood by rotating a first latch in a first opening direction by operation of a first lever disposed within a driver's seat, and by pushing a striker mounted on a lower surface of the hood;
• moving a first link, rotatably connected to a lower end of the first latch, in a second opening direction by rotation of the first latch;
• moving a joint, connected to the first link, and a guide link, connected to the joint, along a guide aperture in the second opening direction;
• rotating the joint in the first opening direction after the guide link comes into contact with a first end of the guide aperture;
• rotating a second link in the first opening direction by rotation of the joint;
• generating collision between a push button portion of an extendable lever and the second lever by rotation of the extendable lever connected to the second link;
• rotating a lever fixing section of the extendable lever about a pin by force that the push button portion is pushed inward from a cover of the extendable lever, to cause a protrusion section to extend outward through a first aperture;
• rotating the extendable lever and the second lever in the first opening direction by force applied to one surface of the protrusion section, to release the striker from a second latch;
• and
• opening the hood after the striker is released.
