Embodiment Construction

[0033] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0034] In this embodiment, a seat that relies on a recliner to adjust the inclination angle of the backrest is taken as an example for illustration, that is, the rotating support body 1 is a recliner.

[0035] Such as figure 1 , 2 As shown in and 3, a seat back unlocking mechanism, the main parts involved are: a rotating support body 1, a back support plate 2, an operating part 3, three sets of limiting members 4, a first elastic element 5 and an assembly part 6 . The rotating support body 1 is the recliner of the seat, which is installed on the seat and is used to adjust the inclination angle of the seat back under normal conditions. The back support plate 2 is fixedly installed on the seat back, and the end of the recliner is set There is an annular boss 1c, and the lower end of the back support plate 2 is provided with a mounting hole 2b, and the mounti...

Abstract

The invention discloses a seat back unlocking mechanism, which comprises a rotating support body and a back support plate capable of rotating relative to the rotation support body. A manipulation component is installed on the back support plate, and one end of the manipulation component is movably connected to a limited position through a first elastic element. component, the position of the back support plate corresponding to the limit member is provided with an assembly hole, and the rotation support is provided with a limit hole. In the locked state, the limit member passes through the assembly hole and is held in the limit hole by the first elastic element. Inside, the rotating support body and the backrest support plate are combined into one body, and the manipulating and manipulating part can make the position-limiting member overcome the resistance of the first elastic element to break away from the position-limiting hole, so that the backrest support plate can rotate relative to the rotation support body under the action of external force. The beneficial effect of the present invention is that: in the locked state, it has extremely high locking strength, and the backrest support plate can remain fixed relative to the rotating support body even in severe situations such as vehicle collision, and the safety factor is high.

Description

technical field [0001] The invention belongs to the technical field of automobile seat components, and in particular relates to a seat back unlocking mechanism. Background technique [0002] As we all know, almost all car seats now have a backrest inclination adjustment function to meet the comfort of riding and the riding of people of different sizes. [0003] In the prior art, the backrest is rotatably mounted on the rotating support body at the rear end of the seat frame, and the inclination adjustment of the backrest refers to changing the inclination angle of the backrest relative to the seat frame through rotation. However, when the inclination adjustment function of the backrest cannot work normally, the backrest will remain fixed and unable to be rotated and adjusted. There is a certain potential safety hazard, and even the passengers and drivers cannot escape in case of an emergency. [0004] Especially in the era of rapid popularization of new energy vehicles, car...
