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] like 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 mounting ...

Abstract

The invention discloses a seat backrest unlocking mechanism. The mechanism comprises a rotary support body, and a backrest supporting plate which can rotate relative to the rotary support body; a control part is mounted on the backrest supporting plate; one end of the control part is movably connected with a limiting component through a first elastic element; an assembling hole is formed in the backrest supporting plate corresponding to the limiting component; a limiting hole is formed in the rotary support body; in a locked state, the limiting component penetrates through the assembling holeand is kept in the limiting hole through the first elastic element, the rotary support body and the backrest supporting plate are combined into a whole, the limiting component can overcome the resistance of the first elastic element to be disengaged from the limiting hole by controlling the control part, and the backrest supporting plate can rotate relative to the rotary support body under the action of external force. The seat backrest unlocking mechanism has the beneficial effects that the mechanism has extremely high locking strength in a locking state, the backrest supporting plate can bekept fixed relative to the rotary support body even under severe conditions such as automobile collision, and the safety coefficient 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...
