Abstract
A seating assembly includes a seat frame, a seat pan coupled with the seat frame, a leg extension assembly coupled with the seat pan, and a calf support assembly disposed under the leg extension assembly and translatable relative to the seat pan. The calf support assembly includes a calf support rotatable about a rotation axis. The rotation axis is translatable relative to the seat pan.
Claims20
A seating assembly comprising:
- a seat frame;
- a seat pan coupled with the seat frame;
- a leg extension assembly coupled with the seat pan;
- a calf support assembly disposed under the leg extension assembly and translatable relative to the seat pan, wherein the calf support assembly includes a calf support rotatable about a rotation axis, and wherein the rotation axis is translatable relative to the seat pan;
- and
- an electromechanical actuator disposed in the calf support and configured to drive rotation of the calf support about the rotation axis.
3 more elements
A seating assembly comprising:
- a seat frame;
- a seat pan coupled with the seat frame;
- a leg extension assembly coupled with the seat pan, the leg extension assembly including an upper leg support, wherein a first actuation unit disposed between the upper leg support and a body of the seat pan provides translational movement to the leg extension assembly relative to the seat pan;
- a calf support operably coupled with the seat pan and pivotable about a rotation axis;
- a guide sleeve disposed under the seat pan configured to receive a rod coupled with the calf support, where the rod is slidable within the guide sleeve to allow translation of the rotation axis;
- a mount fastened to a bottom surface of a structure of the upper leg support and that extends laterally between a first side and a second side of the seating assembly, and wherein the guide sleeve is operably coupled to the mount;
- and
- an electromechanical actuator disposed in the calf support and configured to drive rotation of the calf support about the rotation axis.

A seating assembly comprising:
- a seat frame;
- a seat pan coupled with the seat frame;
- a leg extension assembly coupled with the seat pan, the leg extension assembly including an upper leg support, wherein a first actuation unit disposed between the upper leg support and a body of the seat pan provides translational movement to the leg extension assembly relative to the seat pan;
- and
- a calf support assembly disposed under the seat pan including:
- a first guide sleeve disposed adjacent a first side of the seating assembly;
- a second guide sleeve disposed adjacent a second side of the seating assembly;
- a first rod slidably disposed in the first guide sleeve;
- a second rod slidably disposed in the second guide sleeve;
- a calf support coupled with the first and second rods and translatable relative to the seat pan;
- a crossmember extending between and operably coupling together the first rod and the second rod;
- a mount fastened to a bottom surface of a structure of the upper leg support and that extends laterally between the first side and the second side of the seating assembly, and wherein the first guide sleeve and the second guide sleeve are operably coupled to the mount;
- and
- a first actuator operably coupled with the first and second rods and configured to move the first and second rods through the first and second guide sleeves to translate the calf support between an undeployed position and a deployed position, and wherein the mount extends substantially parallel to the crossmember when the calf support has been deployed by the actuator.
