Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the following embodiments are only used to illustrate rather than limit the present invention.

[0027] The latch unlocking system of the present invention, such as Figure 4 As shown, it includes an upper shell 91 and a lower shell 92 , and the upper shell 91 is slidably fitted with the lower shell 92 through a slide groove structure 95 . A rotating shaft 10 is arranged inside the upper shell 91, and the rotating shaft 10 is matched with a shaft hole of a handle 1 and can be rotated relatively. A handle spring 11 is fixed on the handle 1 , and the other end of the handle spring 11 is overlapped on the upper casing 91 to provide the rotation restoring force of the handle 1 . A driving mechanism 13 is also installed on the handle 1, and the driving mechanism 13 receives the force from the handle 1, thereby providing the drivin...

Abstract

The invention provides a latch unlocking system, which comprises an upper shell and a lower shell slidingly connected with the upper shell, a handle fitted in an inner shaft hole of the upper shell, and a driving mechanism is installed on the handle, wherein the driving mechanism includes A cam and a comfortable sheet, a safety sheet and a stop pawl matched with the cam. The invention changes the original cylindrical driving mechanism of the unlocking handle into a cam structure, so that the safety sheet, the comfort sheet and the stop pawl produce a time difference during the movement, so that the stop pawl will not block the movement of the movable stop, and The comfort piece will not fall in advance to block the lock tongue, so as to realize the function of the lock buckle returning from the second gear position to the first gear position.

Description

technical field [0001] The invention relates to the field of car seats, and more particularly to a buckle unlocking system. Background technique [0002] At present, there is an increasing demand in the market for the design of the rear backrest second gear lock of the car. However, in the design and development of the existing second gear lock, the unlocking handle driving mechanism is cylindrical, such as figure 1 As shown, the active gear point 4' and the gear point pawl 3' will collide during the process of returning to the first gear locked position after the second gear lock position is unlocked, thereby causing the active gear point to fail (such as figure 2 shown); and in the small area that is about to enter the first gear position, the comfort sheet 6' will fall in advance, blocking the movement of the lock tongue 5', causing the lock buckle to fail to return from the second gear position to the first gear position (such as image 3 shown). Contents of the inv...
