The utility model is further arranged to：Second arc panel sets limited towards the side of first arc panel
Position block, the abutting groove for the sliding of the first arc panel is provided with the limited block.
By using above-mentioned technical proposal, the first arc panel is slid in the abutting groove on limited block, so that by the first arc
Plate is close to the second arc panel, skids when preventing the second arc panel from being overturn along the first arc panel outer wall, offsets out the first arc
Shape plate outer wall, causes the locating piece on the second arc panel not slip into limiting slot.
The utility model is further arranged to：The cushion skeleton lower end is provided with securing plate.
By using above-mentioned technical proposal, securing plate can increase the thickness of cushion skeleton, improve the support of cushion skeleton
Power, prevents when pressure is excessive, and damage is produced to cushion skeleton.
The utility model is further arranged to：Reinforcing rib is provided with the securing plate.
By using above-mentioned technical proposal, reinforcing rib can improve the fastness of securing plate, and simultaneous system securing plate is being pressed
Deformation is produced when power is excessive.
In conclusion the utility model has the following advantages：
1st, by the cooperation of locating piece and limiting slot, the fixation between backrest frames and cushion skeleton can be strengthened；
2nd, by limited block backrest frames can be made to be close to cushion skeleton in upset, reduces backrest frames and cushion bone
Gap caused by frame upset.
