Abstract
A furniture member may include a seat base, a seat assembly, a legrest platform, a drive rod, and a sequencing mechanism. The seat assembly is movable relative to the seat base. The legrest platform is coupled to the seat assembly. The drive rod is rotatable relative to the seat assembly, and rotation of the drive rod causes the seat assembly and the legrest platform to move. The sequencing mechanism includes a cam that is attached to the drive rod and a follower wheel that is attached to the seat assembly. The cam is configured to prevent the seat assembly from moving between a first recline position and a second recline position while the seat assembly moves between first and second tilt positions and while the legrest platform moves between first and second legrest positions.
Claims27
A furniture member comprising:
- a seat base;
- a seat assembly movable relative to the seat base, wherein the seat assembly is movable between a first recline position and a second recline position, and wherein the seat assembly is movable between a first tilt position and a second tilt position;
- a legrest platform coupled to the seat assembly and movable between a first legrest position and a second legrest position;
- a drive rod rotatable relative to the seat assembly, wherein rotation of the drive rod causes the seat assembly to move from the first tilt position to the second tilt position and causes the legrest platform to move from the first legrest position to the second legrest position;
- a tilt linkage mechanism including a clevis drivingly engaged to the drive rod and a wheel support panel pivotally attached to the seat base;
- and
- a sequencing mechanism including a cam attached to the drive rod and a follower wheel attached to the seat assembly,
- wherein the cam is configured to prevent the seat assembly from moving between the first recline position and the second recline position while the seat assembly moves between the first tilt position and the second tilt position and while the legrest platform moves between the first legrest position and the second legrest position.
A furniture member comprising:
- a seat base;
- a seat assembly movable relative to the seat base, wherein the seat assembly is movable between an upright position and a reclined position, and wherein the seat assembly is movable between a nominal tilt position and a rearward-tilt position;
- a legrest platform coupled to the seat assembly, wherein the legrest platform is movable between a stowed position and a deployed position;
- a drive rod rotatable relative to the seat assembly, wherein rotation of the drive rod causes the legrest platform to move from the stowed position to the deployed position;
- a support rod rotatable relative to the seat assembly, wherein rotation of the support rod causes the seat assembly to move between the upright position and the reclined position;
- and
- a tilt linkage mechanism including a set of linkages attached the drive rod and the support rod, a first cam attached to the drive rod, and a first follower wheel movable into rolling contact with the first cam, and a wheel support panel rotatably attached to the seat base,
- wherein the tilt linkage mechanism is configured to allow the seat assembly to move between the nominal tilt position and the rearward-tilt position simultaneously while the legrest platform moves between the stowed position and the deployed position and the seat assembly moves between the upright position and the reclined position.
