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 tilt mechanism for a chair comprises a base, a first support configured to support a chair seat and a second support configured to support a chair back, the second support is pivotably coupled to the base. A coupling mechanism couples the second support to both the base and the first support. 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.
