Specific embodiment
As shown in figure 3, structure is folded flat the invention discloses a kind of automobile seat cushion invertible back support, including cushion skeleton 3,
Backrest frames 2, turnover mechanism 6, bottom connecting bracket 5, the turnover mechanism 6, the backrest frames 2 are mounted on the bottom and connect
Connect on bracket 5, the turnover mechanism 6 is connected with the cushion skeleton 3, and the turnover mechanism 6 drive the cushion skeleton 3 into
Row overturning, the backrest frames 2 can carry out overturning folding in the bottom connecting bracket 5.
The turnover mechanism 6 includes first connecting rod 61, second connecting rod 62, third connecting rod 63, the third connecting rod 63 and institute
State cushion skeleton 3 be connected, the first connecting rod 61 is connected with the bottom connecting bracket 5, the second connecting rod 62 respectively with institute
State first connecting rod 61, the third connecting rod 63 is connected, the overturning for passing through the second connecting rod 62 drives turning for the cushion skeleton 3
It is dynamic.
The second connecting rod 62 includes the second left connecting rod and the second right connecting rod, and the first connecting rod 61 is respectively with described second
Left connecting rod is connected with second right connecting rod, the third connecting rod 63 respectively with second left connecting rod and second right connecting rod
It is connected.
Cushion lockable mechanism 4 is installed, cushion lockable mechanism 4 can be well in design position in the cushion skeleton 3
It prevents cushion from shaking, can prompt whether in place to reply by sound when cushion overturns return, prevent passenger's maloperation.
