  • Patent number: 10597909
    Abstract: A door latch device which allows shared use of a connector for use in door latch devices equipped with standard electric components and a connector for use in door latch devices equipped with special electric components in addition to the standard electric components, thereby achieving an increase in the efficiency of the work of connecting to an external connector and a reduction in costs. A connector (32) of a standard switch plate (26) has a coupling hole (51) which penetrates, in the connecting direction of the external connector, a portion having no standard connecting terminals (304). The coupling hole (51) can be fitted with another switch plate (46) that allows the passage of electric current through electric components different than the standard electric components.

  • Patent number: 10597914
    Abstract: A vehicle door latch device comprises an outside lever, a locking lever, a holding member, an opening link and a spring. The spring applies an urging force, smaller than an elastic holding force of the holding member in an unlocking direction, to the opening link. A coil is held in a holding recess of a rotation central portion of the opening link. The first arm engages with the outside lever, and the second arm engages with the opening link. If a panic state occurs, the locking lever can rotate to an unlock position, and the opening link returns to an initial position before a releasing action and is moved to the unlock position by the urging force of the spring.

  • Patent number: 10465424
    Abstract: A vehicle door latch device comprises a latch that can engage with a striker; a ratchet that engages with the latch to hold a door closed; a stationary stopper; a first lever pivotally mounted on a first shaft to rotate from an initial position in a releasing direction; a first spring that biases the first lever toward the initial position, a second lever supported to the first lever on a second shaft and rotating between an initial position where the second lever cannot contact the stationary stopper and a blocking position where the second lever can contact the stationary stopper and prevents the first lever from rotating in the releasing direction; and a second spring that biases the second lever toward the initial position with a force greater than a biasing force of the first spring.

  • Publication number: 20170159334
    Abstract: A motor vehicle door latch device that prevents a latch from being held in a half-latch position when a door opens and enables itself to be smaller. The door latch device comprises a latch that is pivotally mounted via a first shaft to engage with a striker; a pawl that can hold the latch in a full-latch or a half-latch position; a memory lever pivotally mounted via a third shaft not to overlap the latch or the pawl, the memory lever enables holding the pawl in a release position without the full-latch position or half-latch position when the pawl rotates in a releasing direction from the full-latch position; and a releasing portion enabling the pawl to rotate from the release position to the half-latch or full-latch position when the latch rotates from the full-latch position toward an open position to be in between the half-latch position and the open position.

  • Publication number: 20170090146
    Abstract: A lens holder is movably supported by plate springs in a support member provided in a movable unit. Legs of the support member have X direction positioning portions and Y direction positioning portions. Inner facing surfaces of some magnets are in contact with the X direction positioning portions so as to be positioned, and inner facing surfaces of other magnets are in contact with the Y direction positioning portions so as to be positioned. This allows a facing distance to be set without being affected by a variation in thickness among the magnets.
