The invention relates to a foldable foot rest mechanism and a seat. The mechanism includes a base framework unit, a leg rest framework and an operating unit, wherein the base framework unit includes aseat framework with a seat part framework and a slide rail assembly mounted on the seat part framework, the leg rest framework is pivotally connected to the slide rail assembly and pivotably rotatesbetween a folding position and an unfolding position relative to the slide rail assembly around a first pivot axis; the operating unit includes a driving shaft, a driving member, a first connecting rod and a connecting rod driving mechanism, the first connecting rod responds to rotation of the driving shaft and drives the connecting rod driving mechanism to drive the slide rail assembly to move from the folding position or the unfolding position to the unfolding position or the folding position and to drive the leg rest framework to move from the folding position or the unfolding position to the unfolding position or the folding position. More strength is saved when the foldable leg rest mechanism is folded or unfolded, the leg rest framework can be folded at the maximum angle, and the legrest mechanism can be stretched longer after being unfolded.
Description
technical field [0001] The invention belongs to the technical field of furniture, in particular to a folding footrest mechanism and a seat. Background technique [0002] Chairs are office furniture for people to sit while working and studying. Office workers will feel tired after sitting for a long time. In order to relieve work fatigue, office workers need to rest and relax after sitting for a long time. Traditional office chairs are composed of a backrest, a seat cushion, and supportable chair legs. The positions of the backrest and the seat cushion are relatively fixed, and cannot be used for people to lie down and rest. Office workers usually need to purchase additional furniture suitable for lying down to achieve sitting office and lying down to rest, but this requires space in the office space, which is not suitable for offices with narrow spaces. Based on the above problems, some chairs with resting feet have gradually appeared, and the foot rests are integrated with...
