<p>A recliner mechanism for a seat having a seat cushion (2) and an adjustable squab (4) includes a first hinge member (10) attached to the cushion. A ratchet element (18) is mounted on the first hinge member for linear movement in an adjusting direction and has a curved first tooth segment (62) with a first centre of curvature. A cam (20) is mounted on the first hinge member for rotation about a cam axis to control movement of the ratchet. A second hinge member (12) is connected to the first hinge member (10) by a pivot (24) for angular adjustment about a pivot axis and has a curved second tooth segment (50) with a second centre of curvature that coincides with the pivot axis. The ratchet element (18) is adjustable between a locked configuration in which the tooth segments are engaged and an unlocked configuration in which the tooth segments are disengaged. The recliner mechanism has a principal axis that passes through the pivot axis in a direction that is perpendicular to the pivot axis and parallel to the adjusting direction. The first centre of curvature and the drive axis are offset from the principal axis.</p> |
