Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, a back row backrest structure, 1.1, 1.2 is a seat support fixed on a floor by bolts or welding, one side of an angle adjuster 2.1, 2.2 is fixed on the seat support by welding, the other side of the angle adjuster 2.1, 2.2 is fixed on a backrest frame 3 by welding, and the left and right welding surfaces can rotate relatively after the angle adjuster is unlocked, a backrest frame support 4.1, 4.2 is fixed on the backrest frame 3 by bolts or welding, the backrest frame support 4.1, 4.2 is provided with holes and sliding grooves, an armrest frame 5, an armrest rotating shaft 6, and an armrest rear circular tube 7 are welded together, the armrest rotating shaft 6 rotates in the holes of the backrest frame support 4.1, 4.2, and the armrest rear circular tube 7 moves along the sliding grooves of the backrest frame support 4.1, 4.2. On seat left side support pivot 8 was fixed in seat right side support 1.2, latch hook 11 can be around 8 rotary motion of seat left side support pivot, and 9 one end of spring is passed through the hangers on latch hook 11 and is linked to each other with latch hook 11, and the other end of spring 9 is connected on back skeleton left side support pivot 10, and can rotate around back skeleton left side support pivot 10, and back skeleton left side support pivot 10 is fixed in on back skeleton right side support 4.2.

The working principle of the embodiment is as follows:

when the armrest is needed, the occupant pulls the armrest, the armrest framework 5 rotates around the armrest rotating shaft 6, and the armrest rear circular tube 7 moves along the sliding grooves on the backrest framework supports 4.1 and 4.2, as shown in fig. 4.

The handrail continues to rotate until the handrail rear circular tube 7 reaches the end of the sliding groove, and at the same time, the handrail rear circular tube 7 is locked by the hook-type structure at the end of the locking hook 11, as shown in fig. 5.

After the angle adjusters 2.1 and 2.2 are unlocked, the angle of the backrest of the seat is changed, the latch hook 11 rotates around the rotating shaft 8 of the left bracket of the seat, and simultaneously, the rear circular tube 7 of the armrest is pulled to move along the upper chutes of the backrest framework brackets 4.1 and 4.2, so that the angle of the armrest framework 5 is driven to change, and the change of the backrest angle is compensated, as shown in fig. 6.

When the armrest is not needed to be used, the passenger pushes the armrest to rotate, the armrest rear circular tube 7 moves along the sliding grooves in the backrest framework supports 4.1 and 4.2, meanwhile, the armrest rear circular tube 7 is separated from the hook-shaped structure at the tail end of the lock hook 11 until the tail end of the sliding groove, and the armrest is folded, as shown in fig. 3.

When the seat backrest is laid down, the lock hook 11 rotates around the seat left side support rotating shaft 8, one end of the spring 9 moves on the hanging lug of the lock hook 11, and the other end rotates around the backrest skeleton left side support rotating shaft 10, so that the lock hook 11 moves along with the backrest when the seat backrest is laid down until the seat backrest reaches the laying position, as shown in fig. 7.

When the backrest of the seat is turned over, the lock hook 11 rotates around the rotating shaft 8 of the left bracket of the seat, one end of the spring 9 moves on the hanging lug of the lock hook 11, and the other end rotates around the rotating shaft 10 of the left bracket of the backrest framework, so that the lock hook 11 moves along with the backrest when the backrest is turned over until the backrest reaches the upright use position, as shown in fig. 3.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
