Abstract
A pad is adapted to set on a seat pan included in a vehicle seat. The pad includes a cushion on the seat pan and a cushion cover on the cushion.
Claims22
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
- wherein the pad-extension system includes a pan mount coupled to the seat pan in a fixed position, a movable pad support coupled to the pan mount to move relative to the pan mount and the seat pan and coupled to the pad to cause a movable portion of the pad to move relative to the seat pan to cause the occupant-support base to move between the retracted and extended configurations, and a pad-support mover arranged to extend between and interconnect the pan mount and the movable pad support to cause the movable pad support to move relative to the pan mount
- wherein the pad includes a cushion cover located in spaced-apart relation to the seat pan, a cushion located between the cushion cover and the seat pan, and an extension cover member having a first end coupled to an adjustable end of the cushion cover and a second end coupled to the pan mount in a fixed position, and
- wherein the pad-support mover includes a first bracket coupled to the movable pad support and arranged to move in a first direction to cause the movable pad support to move in the first direction to cause the extension cover member to unwind and establish the expanded configuration so that a distance between a first cover guide and an extension cover fixing member decreases, arranged to move in a second direction opposite the first direction to cause the movable pad support to move in the second direction to cause the extension cover member to windup and establish the retracted configuration so that a distance between the first cover guide and the extension cover fixing member increases, and wherein the movable pad support moves by up to about half of a distance the pad moves during movement between the retracted and extended configurations.

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
- wherein the pad-extension system includes a pan mount coupled to the seat pan in a fixed position, a movable pad support coupled to the pan mount to move relative to the pan mount and the seat pan and coupled to the pad to cause a movable portion of the pad to move relative to the seat pan to cause the occupant-support base to move between the retracted and extended configurations, and a pad-support mover arranged to extend between and interconnect the pan mount and the movable pad support to cause the movable pad support to slide relative to the pan mount
- wherein the pad-support mover is a pneumatic actuator including an inflatable bladder.

- 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
- wherein the pad-extension system includes a pan mount coupled to the seat pan in a fixed position, a movable pad support coupled to the pan mount to move relative to the pan mount and the seat pan and coupled to the pad to cause a movable portion of the pad to move relative to the seat pan to cause the occupant-support base to move between the retracted and extended configurations, and a pad-support mover arranged to extend between and interconnect the pan mount and the movable pad support to cause the movable pad support to move relative to the pan mount, and
- wherein the pad includes a cushion cover located in spaced-apart relation to the seat pan and a cushion located between the cushion cover and the seat pan, the cushion cover includes a fixed end located in a fixed position relative to the seat pan, an adjustable end located in spaced-apart relation to the fixed end and configured to move in response to movement of the movable pad support, and a slip belt arranged to extend between and interconnect the adjustable end of the cushion cover and the pan mount.
