9. In Paragraph 5, The above hinge portion is formed in multiple numbers at a rotational radius centered on the rotation axis of the claw, and A latch device for a vehicle characterized in that each of the above hinge portions is provided with the above saddle pawl.
10. In Article 1, The above housing is a base; and It includes a backplate spaced apart from the above base; A latch device for a vehicle characterized in that the above-mentioned operating lever and the above-mentioned second pawl are provided on the outer side of the above-mentioned backplate.

Description

Latch apparatus for vehicle The present invention relates to a latch device for a vehicle. Generally, latch devices installed in vehicles lock and unlock the door during the opening and closing process using mechanical restraining force. In other words, when a user pulls the door handle, the door handle and the latch mechanism are mechanically connected, allowing the door to be unlocked. The latch device used in the door operates according to the operation of the inside handle, outside handle, and inside knob, and a remote controller to operate the latch device may also be additionally installed. Recently, electric vehicles without internal combustion engines are being developed, and vehicle latch mechanisms are evolving into mechanisms that allow for button-type opening rather than steering wheel operation. The background technology of the present invention is disclosed in Korean Published Patent Application No. 2005-0050652 (published May 31, 2005; Title of Invention: Driving Device and Door Closer). FIG. 1 is a perspective view for explaining a latch device for a vehicle according to one embodiment of the present invention. FIG. 2 is an exploded perspective view for explaining a latch device for a vehicle according to one embodiment of the present invention. FIG. 3 is a front view illustrating a latch device for a vehicle according to one embodiment of the present invention. FIG. 4 is a drawing showing the door locking process of a vehicle latch device according to one embodiment of the present invention. FIG. 5 is a drawing showing the door opening process of a vehicle latch device according to one embodiment of the present invention. FIG. 6 is a drawing showing a modified example of a cover bracket of a vehicle latch device according to one embodiment of the present invention. FIG. 7 is an enlarged view of a key part of a latch device for a vehicle according to one embodiment of the present invention. FIG. 8 is a drawing for explaining the operation of a latch device for a vehicle according to one embodiment of the present invention. Hereinafter, an embodiment of a latch device for a vehicle according to an embodiment of the present invention will be described with reference to the attached drawings. In this process, the thickness of lines or the size of components shown in the drawings may be exaggerated for clarity and convenience of explanation. Furthermore, the terms described below are defined in consideration of their functions in the present invention, and these may vary depending on the intent or practice of the user or operator. Therefore, the definitions of these terms should be based on the content throughout this specification. FIG. 1 is a perspective view for explaining a vehicle latch device according to an embodiment of the present invention, FIG. 2 is an exploded perspective view for explaining a vehicle latch device according to an embodiment of the present invention, FIG. 3 is a front view for explaining a vehicle latch device according to an embodiment of the present invention, FIG. 4 is a drawing showing the door locking process of a vehicle latch device according to an embodiment of the present invention, FIG. 5 is a drawing showing the door opening process of a vehicle latch device according to an embodiment of the present invention, FIG. 6 is a drawing showing a modified example of a cover bracket of a vehicle latch device according to an embodiment of the present invention, FIG. 7 is an enlarged view of a key part of a vehicle latch device according to an embodiment of the present invention, and FIG. 8 is a drawing for explaining the operation of a vehicle latch device according to an embodiment of the present invention. Referring to FIGS. 1 to 8, a latch device (100) for a vehicle according to one embodiment of the present invention may include a claw (120) and a foul part (130).
