摘要： The present invention relates to a seat five-link structure (A), comprising a bottom support (1), a wall plate (3), a first front link (4), a second front link (5) and a rear link (2), wherein the bottom support (1) is pivotally connected with the first front link (4) through a first pivot axis (O1), the first front link (4) is pivotally connected with the second front link (5), the second front link (5) is pivotally connected with the wall plate (3), and the rear link (2) is pivotally connected with the bottom support (1) through a second pivot axis (O2) and is pivotally connected with the wall plate (3); a first electric motor (8) configured to output a first external force for driving the first front link (4) to rotate around the first pivot axis (O1); and a second electric motor (12) configured to output a second external force for driving the rear link (12) to rotate around the second pivot axis (O2). The seat five-link structure (A) according to the present invention may have a larger adjustment range of an inclination angle and a seat height, which is beneficial to the realization of a zero-gravity function and allows an occupant better vision and better comfort.
