At least a subset of fluid bladders in each side bolster region are aligned with each other. Pressure in each fluid bladder is selectively adjustable in a plurality of directions. ## Claims ### Claim 1 An apparatus comprising: a seat cushion; a seat back supported relative to the seat cushion, wherein at least one of the seat back and the seat cushion includes at least two side bolster regions spaced apart laterally from each other; a plurality of fluid bladders associated with each of the at least two side bolster regions, wherein at least a subset of fluid bladders in each side bolster region are aligned with each other; and pressure in each fluid bladder is selectively adjustable in a plurality of directions. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein at least a subset of fluid bladders in each side bolster region at least partially overlap each other, and including an actuator assembly that independently controls inflation and deflation of each fluid bladder. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the actuator assembly includes a fluid supply and one or more controllers that regulate inflation and deflation of each fluid bladder. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein the fluid supply is connected to a valve bank, and wherein each fluid bladder has a dedicated valve in the valve bank and a dedicated fluid connection line that connects each fluid bladder to an associated dedicated valve. ### Claim 5 (depends on 2) The apparatus of claim 2, wherein: the plurality of fluid bladders comprise bolster bladders or massage bladders; or the plurality of fluid bladders comprise bolster bladders and massage bladders. ### Claim 6 (depends on 2) The apparatus of claim 2, wherein the subset of fluid bladders in each side bolster region are layered along a linear path and comprise at least a first fluid bladder that comprises a base fluid bladder, a second fluid bladder that rests on top of and partially overlaps the base fluid bladder, and a third fluid bladder that rests on top of and partially overlaps the second fluid bladder. ### Claim 7 (depends on 6) The apparatus of claim 6, wherein the subset of fluid bladders in each side bolster region cooperate with each other such that there is rolling inflation and deflation of the base fluid bladder, the second fluid bladder, and the third fluid bladder along the linear path such that a maximum pressure is selectively movable to a selected location. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein, when the second fluid bladder is inflated, the maximum pressure is movable in a first direction along a vertical linear path or longitudinal linear path by inflating the third fluid bladder while the second fluid bladder deflates, and wherein the maximum pressure is movable in a second direction, opposite of the first direction, by inflating the base fluid bladder while the second fluid bladder deflates. ### Claim 9 (depends on 8) The apparatus of claim 8, the maximum pressure is adjustable in opposing directions along a lateral linear path by inflating and deflating at least one of the base fluid bladder, the second fluid bladder, and the third fluid bladder that is associated with a maximum pressure location along the vertical linear path or the longitudinal linear path. ### Claim 10 (depends on 2) The apparatus of claim 2, wherein pressure in the subset of fluid bladders in each side bolster region of the seat back is adjustable along a vertical linear path, and wherein the pressure is in the subset of fluid bladders in each side bolster region of the seat back is adjustable along a lateral linear path. ### Claim 11 (depends on 2) The apparatus of claim 2, wherein pressure in the subset of fluid bladders in each side bolster region of the seat cushion is adjustable along a longitudinal linear path, and wherein the pressure is in the subset of fluid bladders in each side bolster region of the seat cushion is adjustable along a lateral linear path. ### Claim 12 (depends on 2) The apparatus of claim 2, wherein selected bolster settings are storable within a memory device associated with the actuator assembly, or wherein a plurality of driving modes are each associated with a set of bolster settings that are storable within a memory device associated with the actuator assembly, and wherein bolster pressure is automatically adjusted to the set of bolster settings associated with a selected driving mode of the plurality of driving modes. ### Claim 13 (depends on 1) The apparatus of claim 1, wherein pressure is adjusted via a single switch that is selectively actuatable in multiple directions. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein: the seat back and the seat cushion each have one single switch; or the single switch comprises one switch for both the seat back and the seat cushion, wherein a user assigns the single switch to one of the seat back and the seat cushion via a selection that is input to a user interface. ### Claim 15 (depends on 13) The apparatus of claim 13, wherein the single switch comprises a four-way rocker switch. ### Claim 16 A method comprising: aligning at least a subset of fluid bladders from a plurality of fluid bladders in each side bolster region of a seat cushion or a seat back; and selectively adjusting pressure in one or more fluid bladders of the subset of fluid bladders in a plurality of directions. ### Claim 17 (depends on 16) The method of claim 16, wherein the subset of fluid bladders in each side bolster region comprises at least a first fluid bladder that comprises a base fluid bladder, a second fluid bladder, and a third fluid bladder; and including layering the subset of fluid bladders in each side bolster region along a linear path by resting the second fluid bladder on top of the base fluid bladder and partially overlapping one end of the base fluid bladder, and resting the third fluid bladder on top of the second fluid bladder and partially overlapping one end of the second fluid bladder. ### Claim 18 (depends on 17) The method of claim 17, including selectively moving a maximum pressure to a selected location along the linear path via rolling inflation and deflation of the base fluid bladder, the second fluid bladder, and the third fluid bladder. ### Claim 19 (depends on 16) The method of claim 16, including independently controlling inflation and deflation of each fluid bladder with an actuator assembly that includes a fluid supply and one or more controllers that regulate inflation and deflation of each fluid bladder. ### Claim 20 (depends on 19) The method of claim 19, including: storing selected bolster settings within a memory device associated with the actuator assembly, or associating each driving mode of a plurality of driving modes with a set of bolster settings that are storable within a memory device associated with the actuator assembly, and automatically adjusting bolster pressure to the set of bolster settings associated with a selected driving mode of the plurality of driving modes.
