  • Publication number: 20140117698
    Abstract: A seat lock apparatus includes a guide lever having a waiting hook engagement portion and a striker abutment portion and a hook having a guide engagement portion which, when the hook reaches a waiting position which lies further in a striker releasing direction than a striker releasing position, engages with the waiting hook engagement portion to hold the hook in the waiting position and is disengaged from the waiting hook engagement portion so that the hook restrains the striker. The guide lever has a halfway hook engagement portion which, when the hook is in a halfway position between the releasing position and a restraining position and the striker is not in a position to be restrained by the hook, engages with the guide engagement portion to hold the hook in the halfway position.
