Embodiment Construction

[0066] A door latch assembly for a vehicle according to an embodiment of the present invention will be described with reference to the accompanying drawings. figure 1 is an overall perspective view showing the door latch device 10 of the door latch assembly for a vehicle. A latch unit 11 is provided in an upper portion of the door latch device 10 . The latch unit 11 accommodates a known latch / ratchet mechanism which engages with a striker and which maintains the door in a closed state.

[0067]The door latch device 10 includes a side case 12 disposed substantially orthogonal to the latch unit 11 . The door latch device 10 has a substantially L shape when viewed from above. like figure 2 As shown in , the side case 12 includes a resin case 13 and a resin cover 14 . A door opening mechanism (opening lever, etc.), a locking mechanism (locking lever, etc.), and the like are provided in the side case 12 . The door opening mechanism releases the engagement between the striker...

Abstract

The invention aims to provide a latch assembly for a vehicle door to maintain customary lock operation of a door key cylinder while preventing unlocking at the time of vehicle collision. A latch assembly for a vehicle door includes a door key cylinder of a vehicle door, an outer key lever for switching between a lock state and an unlock state of a lock mechanism by rotation around a shaft part, and a key rod which transmits locking operation and unlocking operation of the door key cylinder to the outer key lever. The outer key lever is configured to receive an inertia of rotation in the locking direction around the shaft part at the time of vehicle collision. The door key cylinder has a configuration in which, when a key plate is rotated clockwise, the outer key lever is lock-rotated through the key rod. A cylinder lever of the door key cylinder 19 extends to a front side of the vehicle to which one end of the key rod is connected.

Description

technical field [0001] The present invention relates to a door latch assembly for a vehicle comprising a door latch device, a door key cylinder and a cylinder lever. Background technique [0002] A conventional door latch device has an engagement mechanism (latch / ratchet mechanism) that engages with a striker to maintain the door in a closed state, and a door opening mechanism (opening lever, etc.) The door opening operation of the door handle releases the engagement between the striker and the engagement mechanism so that the door can be set in an openable state; the locking mechanism (lock lever, etc.), etc., which is used to set the door opening mechanism in the unlocked state and the locked state In the unlocked state, the door opening operation is operable, and in the locked state, the door opening operation is inoperable. The locking mechanism is connected to the door key cylinder of the latch assembly via the cylinder lever of the latch assembly (JP2012-233317A and J...
