Abstract: A seat lock apparatus includes a case member having a striker entrance groove and a hook lever that is provided rotatably via a hook shaft and is movable between an opening position and a restraining position where the hook lever closes an opening in a striker entrance groove. The apparatus is configured to position the hook lever in the restraining position while positioning the striker in the striker entrance groove when a seatback is erected. The striker entrance groove is formed such that when the striker enters the striker entrance groove and abuts against the hook lever positioned in the restraining position, only a portion of the case member, which is positioned closer to a central side of the seatback than the hook lever is in an axial direction of the hook shaft, is brought into abutment with the striker.

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.
