Abstract
A system for moving a furniture member headrest includes an armrest fixedly connected to a base. A back support is connected to the armrest. A headrest is movably connected to the back support. A first adjustment member operates to rotate the headrest. The first adjustment member is positioned in a cavity between interior and exterior armrest frame elements and is manually movable. A second adjustment member moves the headrest upwardly or downwardly with respect to the backrest. The second adjustment member is also positioned in the cavity and manually movable by the occupant.
Claims27
A furniture member headrest control system, comprising:
- an armrest portion of a furniture member having interior and exterior armrest frame elements;
- a back support portion connected to the armrest portion;
- a headrest portion movably connected to the back support portion;
- a first adjustment member operable to rotate the headrest portion, the first adjustment member positioned in a cavity created between the interior and exterior armrest frame elements, the first adjustment member manually movable by an occupant of the furniture member;
- an actuation arm rotated by a force received from the first adjustment member;
- and
- an actuation link rotatably connected at a first end to the headrest portion and at a second end to the actuation arm, such that rotation of the actuation arm operates to displace the actuation link to rotate the headrest portion to a plurality of headrest support positions.
A furniture member headrest control system, comprising:
- an armrest portion fixedly connected to a base portion of a furniture member;
- a back support portion connected to the armrest portion;
- a headrest portion movably connected to the back support portion;
- a first adjustment member operating to rotate the headrest portion, the first adjustment member positioned in a cavity created between interior and exterior armrest frame elements of the armrest portion and manually movable by an occupant of the furniture member;
- and
- a second adjustment member operating to upwardly and downwardly move the headrest portion with respect to the back support portion, the second adjustment member positioned in the cavity and manually movable by the occupant;
- and
- an actuation link rotatably connected at a first end to the headrest assembly and linked at a second end to the first adjustment member, such that movement of the first adjustment member displaces the actuation link to rotate the headrest assembly to a plurality of support positions.
A furniture member headrest control system, comprising:
- a mechanism having at least first and second lever members;
- an actuation assembly connected to the first lever member;
- an actuation link connected between the actuation assembly and a headrest portion, manual movement of the first lever member operating to rotate the headrest portion between a rearward rotated position and a forward rotated position;
- and
- a cable linking the second lever member to a headrest subassembly of the headrest portion, manual movement of the second lever member operating to displace the cable thereby displacing the headrest subassembly between a downward position and an upward extended position.
A method for adjusting a position of a headrest portion of a furniture member, the furniture member including a base portion, an armrest portion fixed to the base portion, a back support portion connected to the armrest portion, and first and second lever members both movable in a first direction and an opposite second direction, the method comprising:
- displacing the first lever member in the first direction to rotate the headrest portion from a headrest back position to a headrest forward position;
- restraining the headrest portion in a headrest retracted position against a biasing force of a biasing element;
- and
- displacing the second lever member in the first direction to allow the biasing force of the biasing member to upwardly extend the headrest portion away from the back support portion to a headrest extended position.
