摘要： A high-load recline mechanism may include a first pair of linkage mechanisms positioned proximate a right side of a base and may also include a second pair of linkage mechanisms positioned proximate the left side of the base. The first pair of linkage mechanisms may be coupled together such that they both move between a closed position and a fully reclined position in unison. The second pair of linkage mechanisms may also be coupled together such that they both move between a closed position and a fully reclined position in unison. A motor drive tube may be coupled to the each of the inside linkage mechanisms of each pair of mechanisms in order to drive all of the linkage mechanisms between the closed position and the fully reclined position in unison. A linear actuator may be coupled between the motor drive tube and the base to actuate the recline mechanism.

摘要： An adjustable lumbar support mechanism for adjusting a position of a lumbar support in a seating unit is provided. The mechanism includes a pair of spaced apart swing links that are pivotally coupled on an upper end to the back frame of the seating unit. The lower free end of each swing link is coupled to a lumbar support. An actuating mechanism is coupled on an upper end to the back frame, and on a lower end is pivotally coupled to the lumbar support. Extending the shaft of the actuating mechanism extends the lumbar support providing additional support to someone sitting in the seating unit.
