Title:
DOOR LATCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/070401
Kind Code:
A1
Abstract:
In order to more reliably prevent a situation in which a door opens unnecessarily, an open link 20 is provided with a lever main body 21 which moves in conjunction with a door handle opening operation, an inertial lever portion 22 which is disposed in such a way as to be capable of rotating about a prescribed axis relative to the lever main body 21 and capable of sliding along the axis, and which moves, by rotation, between an operating position and a non-operating position, and a torsion coil spring 24 which urges inertial lever portion 22 relative to the lever main body 21 such that the inertial lever portion 22 is maintained in the operating position, wherein, when the inertial lever portion 22 is rotated toward the non-operating position against the rotational-direction urging force of the torsion coil spring 24, the axial-direction urging force of the torsion coil spring 24 causes the inertial lever portion 22 to slide along the axis relative to the lever main body 21, causing a block portion 21B of the lever main body 21 and a block portion 22B of the inertial lever portion 22 to face one another in the circumferential direction, thereby restricting movement returning the inertial lever portion 22 to the operating position.
