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.
