Abstract: A tilt mechanism for a weight-responsive seating furniture comprises a backrest support, a first lever and a second lever. The backrest support is configured for coupling to a backrest and is pivotably mounted. The first lever has a mount structure for coupling the first lever to a seat. The first lever is pivotably mounted at a first pivot axis. The second lever is pivotably attached to the backrest support at a second pivot axis and is coupled to the first lever by a coupling mechanism to pivot the first lever about the first pivot axis when the backrest support pivots relative to the carrier.

Abstract: A control mechanism for a chair comprises a baseplate configured to be coupled to a chair base assembly, a support plate configured to be coupled to a chair seat, and an elastic element arranged between the base plate and the support plate. The elastic element enables the support plate to be tilted with respect to the base plate around a first tilt axis and a second tilt axis different from the first tilt axis. The control mechanism further comprises a control handle configured to be actuated in an actuating direction, and at least one stop element. Each stop element is arranged between the base plate and the support plate and configured to limit a minimum distance between the base plate and the support plate at the position of the corresponding stop element. A stop element adjust mechanism is coupled to the control handle and configured to adjust the minimum distance of each stop element in response to actuating the control handle in the actuating direction.

Abstract: A chair back height adjustment mechanism comprises a guide having an abutment surface at a lateral side of the guide which extends along an adjustment direction. The chair back height adjustment mechanism comprises an adjusting device supported on the guide so as to be displaceable along the adjustment direction. The adjusting device comprises a carrier, a coupling member which is moveably supported on the carrier, and a bias mechanism. The coupling member has a contact face shaped to abut on the abutment surface of the guide and a slanted face. The bias mechanism is operative to apply a force onto the slanted face to urge the contact face of the coupling member against the abutment surface of the guide.

Abstract: A tension adjust device (20) for a chair comprises a carrier member (21), an actuation member (22), a ratchet mechanism and a disengagement mechanism. The actuation member (22) is rotatable in a first direction and in a second direction opposite to the first direction and is coupled to the carrier member (21) to rotate the carrier member (21). The ratchet mechanism (31-33) is coupled between the actuation member (22) and the carrier member (21) and comprises a locking pawl (31) and a profile (32) having a plurality of recesses for engagement with the locking pawl (31). The disengagement mechanism is configured to maintain the ratchet mechanism (31-33) in a disengaged state when the actuation member (22) rotates the carrier member (21) in the second direction. The locking pawl (31) remains disengaged from the recesses of the profile (32) while the ratchet mechanism (31-33) is in the disengaged state.

Abstract translation: 用于椅子的张力调节装置（20）包括承载构件（21），致动构件（22），棘轮机构和分离机构。 致动构件（22）可沿第一方向和与第一方向相反的第二方向旋转，并且联接到承载构件（21）以使承载构件（21）旋转。 棘轮机构（31-33）联接在致动构件（22）和承载构件（21）之间，并且包括锁定爪（31）和具有多个凹槽的轮廓（32），用于与锁定爪 31）。 分离机构构造成当致动构件（22）沿着第二方向旋转承载构件（21）时，将棘轮机构（31-33）保持在分离状态。 当棘轮机构（31-33）处于分离状态时，锁定爪（31）保持与轮廓（32）的凹部脱离。
