TILT MECHANISM FOR A CHAIR AND CHAIR

摘要

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 coupling mechanism (41) couples the second support (13) to both the base (11) and the first support (12). The coupling mechanism (41) comprises a pin (40) attached to the first support (12), a first linear guide slot (20) provided on the base (11), and a second linear guide slot (36) provided on the second support (13). The pin (40) is slideably received in both the first linear guide slot (20) and the second linear guide slot (36). The second linear guide slot (36) slopes upwardly in a forward direction of the tilt mechanism (10) when the tilt mechanism (10) is in a zero-tilt position.
