Patent number: 10267069Abstract: A door latch actuator comprises a reversible motor, a rotating object, a drive portion and an actuating member. The drive portion comprises two locking/unlocking drive projections and stopping projections. The actuating member comprises a pair of driven portions. When the drive portion is rotated in one direction, one of the locking/unlocking drive projections comes in contact with one of the driven portions to move the actuating member to a lock position.

Publication number: 20190032373Abstract: A motor-vehicle door latch device having a latch releasing member and a stopper which are rotatably supported on a base member by each shaft. The stopper holds the latch releasing member so as not to rotate in a releasing direction by rotating from a regular position to a lock position, due to an action of an inertial force caused by an impact force which is received from a first direction corresponding to a direction in which a striker enters an entrance groove. The latch releasing member has a center of gravity which deviates from its rotation center so that another inertial force, caused by another impact force which is received from a second direction opposite the first direction, acts in an opposite direction to the releasing direction.Type: ApplicationFiled: February 2, 2016Publication date: January 31, 2019Applicant: MITSUI KINZOKU ACT CORPORATIONInventor: Takao TAGA
