As preferably, described leg-placing plate link, connector A or connector B are provided with the position limiting structure of restriction leg-placing plate link scope of activities.
As preferably, described bottom bar, fixed bar, fixture, connector I and connecting rod are straight square tube and make.Stable, the low cost of manufacture of sound construction like this.
As preferably, described connector F, connector D or fixture are provided with the position limiting structure of restriction connector F scope of activities.
One end and the bottom bar of described electric pushrod are hinged, and the other end and the connecting rod of electric pushrod are hinged.
A kind of seat, comprise base, cushion, backrest, leg-placing plate and functional frame as above, the bottom of base fixedly mounts described bottom bar, two fixtures that described left and right is oppositely arranged are fixedly mounted on respectively the both sides of base, on described base or fixed bar, cushion is installed, backrest is installed in the upper end of two backrest links that described left and right is oppositely arranged, and on two leg-placing plate links that described left and right is oppositely arranged, leg-placing plate is installed.
The utility model, owing to having adopted above technical scheme, improves mechanical linkage structure, has reduced the complexity of system, has improved stationarity, the comfort of action, easy to use, rational in infrastructure,
Save space, and simple in structure, be convenient to transportation and assembling.
