Abstract

The invention discloses a stool-couch linkage device, a frame body and a seat, and belongs to the technical field of seats. The stool-couch linkage device comprises an upper connecting rod, a lower connecting rod, a middle stool and couch connecting rod, a first front stool and couch connecting rod, a second front stool and couch connecting rod, a first connecting rod, a second connecting rod, a front stool and couch support and a middle stool and couch support, and the upper connecting rod or the lower connecting rod can be driven by driving force to rotate so that the stool and couch linkagedevice can be unfolded or folded. The driving force of the first connecting rod can be adjusted by changing the length of the first connecting rod and the length of the second connecting rod, whereinthe first front stool couch connecting rod and the second front stool couch connecting rod which are split are adopted, so that the length of the second front stool couch connecting rod can be increased, and the second front stool couch connecting rod is matched with the first connecting rod and the second connecting rod; therefore, the deformation area of the small quadrangle is enlarged. Meanwhile, the action of the middle stool couch bracket is not influenced, so that the distance between the front stool couch bracket and the middle stool couch bracket can be increased.

Description

technical field

[0001] The invention relates to the technical field of seats, in particular to a stool couch linkage device, a frame body and a seat. Background technique

[0002] Many seats currently on the market include retractable reclining cushions. The reclining cushions can be unfolded for people to lie down and have a rest, and the reclining cushions can be used as normal seats when folded. Yet these seats are owing to the restriction of self structure, and the distance between footrest and lying cushion is fixed, can not be suitable for the use of people with different heights. Moreover, the driving force of these seats is fixed and cannot be adjusted, and the problem of unsmooth expansion and contraction of the lying cushion often occurs. Contents of the invention

[0003] The first object of the present invention is to provide a stool linkage device, which can increase the distance between the front stool support and the middle stool support, and the driving fo...
