The size of the gaps (66, 66', 70, 70') determines the firmness or "feel" of the pocketed spring assembly (12, 12a, 12b, 12d, 12e, 12f, 12g) or portion thereof.
Feedback-based systems and methods for bending wire are provided.

Modifications to the wire-bending process may occur in real time without stopping the wire-bending process. Furthermore, a wire may be bent into a sinusoidal wire structure for forming springs for use in various applications.

The coupling mechanism comprises a pin attached to the first support, a first linear guide slot provided on the base, and a second linear guide slot provided on the second support. The pin is slideably received in both the first linear guide slot and the second linear guide slot. The second linear guide slot slopes upwardly in a forward direction of the tilt mechanism when the tilt mechanism is in a zero-tilt position.
Modern chairs include chair backs with tension adjustment devices for adjusting forces applied to the occupant. The tension adjust device comprises a carrier member, an actuation member, a ratchet mechanism and a disengagement mechanism. The actuation member is rotatable in first and second opposite directions, and is coupled to the carrier member for rotation thereof. The ratchet mechanism is coupled between the actuation member and the carrier member and comprises a locking pawl and a profile with recesses for engagement with the locking pawl. The disengagement mechanism maintains the ratchet mechanism in a disengaged state when the actuation member rotates the carrier member in the second direction. The locking pawl remains disengaged from the recesses of the profile while the ratchet mechanism is in the disengaged state. The disengagement mechanism selectively disengages the ratchet mechanism depending on a rotation direction of the actuation member and the carrier member.

A tilt mechanism (10) for a is configured for adjustment of a tension applied by a chair back. The tilt mechanism (10) includes a base (11), a back bracket (13) tiltably supported on the base (11), and a rocker (12) coupled to the back bracket (13) so as to be moveable relative to the back bracket (13). The rocker (12) has a pivot axis (15) and pivots about the pivot axis (15) when the back bracket (13) tilts relative to the base (11). An energy storage mechanism (23) is coupled to the rocker (12) to exert a force (28) onto a portion (24) of the rocker (12). An actuating mechanism is coupled to at least one of the rocker (12) or the energy storage mechanism (23) and is configured to alter a distance (34) between the pivot axis (15) and the portion (24) of the rocker (12) at which the force (28) is exerted onto the rocker (12), thereby altering a length of a lever arm.
A tilt mechanism (10) for a chair comprises a base (11 ), a first support (12) configured to support a chair seat and a second support (13) configured to support a chair back. The second support (13) is pivotably coupled to the base (11 ). A first coupling mechanism (41) couples the first support (12) with the base (11 ) and includes a first pin (40) slideably supported in a first linear guide slot (20). A second coupling mechanism (42) couples the second support (13) with the first support (12) and includes a second pin (44) slideably supported in a second linear guide slot (36). When the second support (13) pivots relative to the base (11), the first pin (40) is caused to be displaced along the first linear guide slot (20) and the second pin (44) is caused to be displaced along the second linear guide slot (36).
Rocker-recliner-style and glider-recliner-style seating units that include linkage mechanisms for adjusting the respective seating units between closed, extended, and reclined positions are provided. The seating units are each powered by a linear actuator that facilitates automated adjustment of the respective linkage mechanisms. This adjustment of the linear actuator is sequenced into a first phase and a second phase. A stroke of the linear actuator in the first phase acts to adjust a linkage mechanism between the closed and extended positions by extending or retracting ottoman(s) attached to a footrest assembly. A stroke in the second phase acts to adjust a linkage mechanism between the extended and reclined positions by translating a seat-mounting plate forward or rearward at a consistent inclination angle while, concurrently, tilting a back-mounting link. Accordingly, the phase sequencing ensures that each linkage mechanism commences adjustment within the second phase only once the first-phase adjustment is substantially complete.
Various methods for installing an article of fabric to a frame to provide an improved seating product, which can be integrated in essentially any type of seating unit, are provided. These methods include a pre-forming operation that deforms the frame prior to securing the fabric article thereto, and a securing operation that leverages post-mold shrinkage properties of the frame to secure the fabric article thereto. The pre-forming operation generates tension in the fabric article, which spans the frame, by initially deforming the frame utilizing compression mechanisms of an assembly fixture and subsequently loading the fabric article to the frame in a loose condition. Upon releasing the compression mechanisms, the fabric article assumes a taut condition that expresses the tension. The securing operation involves inserting a segment of the fabric article into a groove in the frame and allowing the groove to naturally clamp the segment during post-mold shrinkage.

ROCKER-RECLINER BASE ASSEMBLY HAVING UNITARY CAM MEMBERS
A rocker chair base assembly employs a set of unitary composite cam members to enable a user to engage in a rocking motion with a chair mounted over the assembly. Each cam member presents a rigid body with a set of laterally projecting sleeves. A first set of angle cross members serve to interconnect longitudinal rails on which the cam members reside, and a second set of angle cross members serve to interconnect adjacent cam members. Specifically, the laterally projecting sleeves of each cam member present a mating angle profile for slidably receiving therein and securely attaching with longitudinal end regions of the second set of angle cross members.
A tilting device is for a reclining chair possessing an adjustable seat. A support base is for a pedestal. A mounting body is for a seat back rotatably articulated to the support base around a first axis orthogonal to the pedestal. A mounting plate has a front end rotatably articulated around a first hinge axis to the support base and a back end rotatably articulated around a second hinge axis to the mounting body. The first and second hinge axes are parallel to said first axis. The elastic means acts orthogonal to said first axis and has a first end acting on the support base and a second end acting on the mounting body. The blocking means positions the mounting body. The mounting plate rotates around the second axis when the mounting body is positioned in at least two different angles to assume at least two corresponding different angles.

A support system comprises a hub comprising a channel, a leg comprising a finger that slideably engages the channel, and a washer that prevents the finger from disengaging the channel, wherein a multi-dimensional force is exerted that tightens the connection therebetween when the hub, the leg, and the washer are connected together. A method of connecting a support system for an article of furniture comprises inserting a finger of a leg into a channel of a hub to form a mating connection therebetween, connecting a washer to the hub to maintain the finger within the channel, and exerting a multi-dimensional force to secure the leg to the hub.
Disclosed herein is a bedding or seating product (10) having a spring core (12) comprising coil springs (26) having unknotted end turns (72, 74) made from high tensile strength wire. In each embodiment, the end turns (72, 74) of the coil springs (26) are generally U-shaped having one leg (76) longer than the other (78), the legs (76, 78) being joined by an arcuate connector (80). The springs (26) are oriented in the spring core (12) such that a long leg (76) of one end turn (72) abuts a short leg (78) of the adjacent end turn (72) prior to be wrapped in helical lacing wire (32). The high tensile wire enables the coil springs (26) to be manufactured using less wire than heretofore possible.
