主权项

1. An occupant-support base comprises
a seat pan including an outer surface adapted to face toward an occupant supported by the occupant-support base, an inner surface arranged to face opposite the outer surface away from the occupant, and a perimeter surface arranged to extend between and interconnect the inner and outer surfaces of the seat pan, a pad coupled to the seat pan and adapted to be located between the seat pan and an occupant, the pad including an outer pad surface arranged to face away from the seat pan and an inner pad surface arranged to face toward the seat pan, and a pad-extension system configured to provide means for moving a portion of the pad relative to the seat pan between a retracted configuration in which the pad has a first dimension measured between the perimeter surface of the seat pan and a portion of the inner pad surface which confronts the perimeter surface of the seat pan and an extended configuration in which the pad has a relatively greater second dimension measured between the perimeter surface of the seat pan and the portion of the inner pad surface without causing a gap to be formed in a portion of the outer pad surface of the pad during movement from the retracted configuration to the extended configuration.
