Title:
DOOR LATCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/149061
Kind Code:
A1
Abstract:
In order to more reliably prevent a door from being unnecessarily opened, an open link 20 comprises a lever body 21, an inertia lever part 22, and a torsion coil spring 24. Only when the lever body 21 is located in an unlock position and the door handle is operated to open with the inertia lever part 22 placed in an active position, the inertia lever part 22 can transmit an operation force thereof to a ratchet lever 14a. The torsion coil spring 24 functions to tilt the inertia lever part 22 with respect to the lever body 21 when the inertia lever part 22 rotates and reaches a sensing position against the biasing force of the torsion coil spring 24. The lever body 21 is provided with a regulating projection part 21Ba that faces a block part 22B when the inertia lever part 22 in the tilted state is biased in a rotation direction by the torsion coil spring 24, thereby inhibiting the inertia lever part 22 from moving to the active position through the sensing position.
