Patent number: 9187936Abstract: A two step link hood latch apparatus for a vehicle allows a hood to be opened only with an operation of a release handle inside a vehicle. The apparatus includes a claw, the pawl, a pivot, and a link. The claw is disposed at a base plate to be rotatable, restrains a hood striker through a stop groove, and is restrained to a pawl through first and second stop ends in first step and second step lock states. The pawl is disposed at the base plate to be rotatable, and restrains the rotation of the claw in steps by using the stop protrusion. The pivot is disposed at the base plate to be rotatable in a hinge structure, and transmits a pulling force generated from the release handle. The link connects the pivot and the pawl and rotates the pawl in linkage with the pivot.Type: GrantFiled: December 6, 2012Date of Patent: November 17, 2015Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Sang Il Kim, Chung Hwa Jung, Chang Gi Ha, Ki Ryun Ahn, Mun Bae Tak
