Seat and related leg rest and mechanism and method therefor

A leg rest mechanism suitable for use together with a seat pad of a seat in a passenger vehicle, said leg rest mechanism comprising:

• a support member adapted for supporting a passenger's leg,
• said support member being moveable between
• a stowed position in which the support member is stowable under the seat pad of the passenger vehicle seat and;
• an extended position in which the support member defines a substantially horizontal surface on which a passenger is at least partially supportable;
• and
• at least one intermediate position located between the stowed position and an intermediate limit between the stowed position and the extended position;
• and
• an extension arrangement for supporting the support member in the intermediate position and the extended position, said extension arrangement, including
• an adjustable support mechanism for only supporting the support member in the intermediate position between the stowed position and the intermediate limit,
• a horizontal support mechanism for supporting the support member in the extended position;
• and
• a lost motion arrangement for disengaging the support member from the adjustable support mechanism such that the support member may be moved from the intermediate limit to the extended position,
• wherein the support member is only manually moveable between the extended position and the intermediate limit.

A leg rest of a seat, that can move between a stowed position adjacent and below the seat pan of the seat and a fully extended position adjacent and substantially co-planar with the seat pan, said leg rest comprising;

• a leg rest pad adapted for supporting the legs of a passenger sitting in the seat, the leg rest pad pivotally mounted to said seat to pivot about an axis perpendicular to the seat facing direction between the stowed position and the fully extended position, passing through an intermediate limit position intermediate of the stowed position and the extended position;
• an extension arrangement for pivotally moving the leg rest pad between the stowed position and the extended position and for holding the leg rest pad at least in the extended position, and
• an actuator to cause movement of the extension arrangement;
• wherein the actuator can only cause movement to move the leg rest pad between the stowed position and the intermediate limit position, and
• wherein movement of the leg rest pad from the intermediate limit to the extended position is only via direct manual manipulation of the leg rest pad.
