A latch device including: a latch mechanism configured to hold a door at a closing position; an electric releasing mechanism configured to release meshing of the latch mechanism; a manual releasing mechanism configured to release meshing of the latch mechanism; and a lock configured to switch between a locked state of the manual releasing mechanism and an unlocked state, wherein the electric releasing mechanism is configured to switch the lock from the locked state to the unlocked state by releasing meshing of the latch mechanism and switch the lock from the unlocked state to the locked state when a rotating cam returns to a reference position by a biasing force of a spring, when the lock is in the locked state and the rotating cam rotates by a predetermined angle in a first direction from the reference position by power of a motor against a biasing force of the spring.

Automobile door latch device

A vehicle door latch device includes: a latch body including: a latch secured by a latch shaft on a rear surface side of the latch body, the latch being configured to engage with a striker; a ratchet secured by a ratchet shaft on the rear surface side of the latch body, the ratchet being configured to engage with the latch; and a striker advancing path into which the striker advances relatively; a motor configured to release the ratchet from the latch; and an actuator case provided continuously on top of the latch body, the actuator case being configured to accommodate the motor.

Vehicle door latch device

A vehicle door latch apparatus has a latch that is engaged with a striker; a ratchet member rotatably supported by a ratchet shaft and that has a pawl portion, wherein the pawl portion is movable between a latch engaging position, where the pawl portion can face a full latch engaging portion of the latch, and a latch releasing position, where the pawl portion is not in contact with the full latch engaging portion, wherein release component force is generated in a latch releasing direction when latch return force is applied in a releasing direction at the latch engaging position, and the ratchet member is pushed out from the latch engaging position to the latch releasing position by the release component force; a ratchet restraint that is arranged on a side of the ratchet member and that can be moved about a pin between a block position and a release position.

Vehicle door latch apparatus

Vehicle door latch apparatus has; latch that engages strike and that rotates from an unlatched position to a full-latch over rotating position; ratchet member that is rotatably supported by ratchet shaft, wherein ratchet member has pawl portion that is movable between a latch engaging position, where pawl portion can face full-latching engaging portion of latch, and a latch releasing position, where pawl portion is not engaged with full-latching engaging portion; and ratchet restrainer that is positioned on a side of ratchet member and that restrains ratchet member. Ratchet member is configured to be pushed out from latch engaging position to a latch releasing position by release component force Fthat acts on ratchet member in a latch releasing direction, wherein release component force Fis generated when latch returning force that acts on latch is applied to ratchet member at the latch engaging position.

A vehicle door latch apparatus has latch mechanism, powered release means, manual release means and lock mechanism that is switched between a locked state and an unlocked state. Powered release means has cam wheel that is rotated in normal and in reverse rotational directions from a reference position by motor power. When cam wheel is rotated in the normal rotational direction from the reference position, latch mechanism is released while lock mechanism is held in the locked state When cam wheel is rotated in the reverse rotational direction from the reference position, cam wheel switches lock mechanism to the unlocked state. Cam wheel returns lock mechanism to the locked state when cam wheel is rotated in the normal rotational direction back to the reference position in the unlocked state.

Lock mechanism is provided between pawl lever and manual release mean. The present vehicle door latch apparatus includes ratchet member that engages latch and that can be released from latch by release component force F, latch restraint that prevents ratchet member from being disengaged from latch and powered release means that moves ratchet restraint. Ratchet member includes base lever and pawl lever. When ratchet restraint is moved, base lever is moved to a non-regulated position, where pawl lever can be disengaged from latch by release component force F. Manual release means is connected to pawl lever. Lock mechanism is provided between pawl lever and manual release means.

An action with a handle on a vehicle is transmitted to an operational unit in a door, and then to a locking-unlocking unit via a first action-transmitting member. The locking-unlocking unit allows the door latch to disengage from a striker of the vehicle via a second action-transmitting member. The door of the vehicle opens.

Device for operating a door latch in a vehicle

An automotive door construction is configured so that a door trim is divided into an upper trim and a lower trim ; a glass elevating mechanism is installed on the inside surface of the lower trim so that the upper end of a guide rail projects upward from the upper edge of the lower trim ; and the glass elevating mechanism is inserted from the upper end of the guide rail of the glass elevating mechanism through a mount hole in an inner panel and is housed in a door bag portion and then the lower trim is lowered along the inner panel by which the glass elevating mechanism and lower trim are installed to the inner panel By forming the relatively small mount hole which is shorter than the total length of the guide rail in the inner panel the modularized glass elevating mechanism is incorporated in the door bag portion Therefore, the automotive door construction in which a modularized glass elevating mechanism can be incorporated without the formation of a large mount hole in the inner panel can be provided.

Automotive door construction

A guide plate has at the front and rear ends thereof a pair of guide rail portions on which a pair of sliders are movably mounted for guiding movement of a door glass. The guide plate also mounts thereon a drive unit for driving the door glass at a point located between the sliders.

Automotive window regulator

A roller unit of a window regulator is movably engaged with a guide rail of a U-shaped cross section. The guide rail has a pair of parallel side walls one of which is formed with a longitudinal groove of a V-shaped cross section and the other is formed to be planar. The roller unit includes a pair of convexly surfaced rollers in rolling contact with the grooved side wall and a flat surfaced roller in rolling contact with the planar side wall. The flat surfaced roller is movable toward and away from the planar side wall and urged against the same by a spring.
