A patient support apparatus includes a base, a frame coupled to the base, a deck supported by the frame and capable of moving relative to the frame, and a siderail assembly movable between a raised position above the deck and a first lowered position below the deck. The patient support apparatus further includes a siderail mover coupled to the deck to move the siderail assembly from the first lowered position to a second lowered position in response to movement of the deck relative to the frame.

The patient support apparatus of claim 1, wherein the siderail mover includes a foot-section ramp coupled to the foot section between a head edge of the foot section and a foot edge of the foot section. 3. The patient support apparatus of claim 2, wherein the foot-section ramp includes a foot-ramp surface and the foot-ramp surface cooperates with the first plane to define a foot-ramp angle therebetween. 4. The patient support apparatus of claim 3, wherein the foot-ramp angle is about 45 degrees. 5. The patient support apparatus of claim 4, wherein the siderail mover further includes a siderail ramp coupled to the barrier and the siderail ramp engages the foot-section ramp during movement of the barrier from the first lowered position to the second lowered position. 6. The patient support apparatus of claim 5, wherein the siderail ramp includes a siderail-ramp surface and the siderail-ramp surface cooperates with the first plane to define a siderail-ramp angle. 7. The patient support apparatus of claim 6, wherein the siderail-ramp angle is about 45 degrees. 8. The patient support apparatus of claim 1, wherein the siderail mover includes a siderail ramp coupled to the barrier and the siderail ramp is configured to engage the foot section during movement of the foot section from the substantially horizontal position to the substantially vertical position. 9. The patient support apparatus of claim 8, wherein the siderail ramp includes a siderail-ramp surface and the siderail-ramp surface cooperates with the first plane to define a siderail-ramp angle. 10. The patient support apparatus of claim 9, wherein the siderail-ramp angle is about 45 degrees. 11. The patient support apparatus of claim 1, wherein the siderail mover is an actuator coupled to the frame to move relative to the frame between a retracted position in which the actuator has a first length and the barrier is in the first lowered position and an extended position in which the actuator has a second length greater than the first length and the barrier is in the second lowered position. 12. The patient support apparatus of claim 11, wherein the actuator is electrically coupled to a bed controller included in the patient support apparatus and the bed controller causes the actuator to move from the retracted position to the extended position in response to movement of the foot section from the substantially horizontal position to the substantially vertical position. 13. A patient support apparatus comprising a base,a frame coupled to the base to move relative to the base,a deck supported by the frame, the deck including a head section movable relative to the frame, a foot section spaced-apart from the head section and movable about a lateral pivot axis between a horizontal position and a vertical position, the foot section including a top surface arranged to face in an upward direction away from the base and the frame and a bottom surface arranged to face in an opposite downward direction toward the base and the frame, a seat section positioned between the head section and the foot section, the seat section including a top surface arranged to face in the upward direction and a bottom surface arranged to face in the downward direction, and a foot ramp coupled to the bottom surface of the foot section to move therewith,a barrier including an inward side arranged to face toward the deck and an oppositely facing outward side, the barrier being movable relative to the deck between a raised position in which the barrier is above the top surface of the seat section and defines a first support width and a first lowered position in which the barrier is positioned below the bottom surface of the seat section and defines a second support width, the second support width being smaller than the first support width,and a siderail ramp coupled to the inward side of the barrier,wherein the barrier when in the first lowered position causes the siderail ramp to cooperate with the foot ramp to move the barrier in an outward direction away from the seat section of the deck a distance sufficient to permit rotation of the foot section in a first direction about the lateral pivot axis so that the foot section assumes the vertical position without touching the barrier. 14. The patient support apparatus of claim 13, wherein the foot section includes a foot edge, a head edge spaced-apart from and generally parallel to the foot edge, a first longitudinal edge extending between the head and the foot edges, a second longitudinal edge spaced-apart from and generally parallel to the first longitudinal edge, and the top surface of the foot section extends between the foot, the head, the first longitudinal, and the second longitudinal edges and the bottom surface of the foot section is spaced-apart below and extends between the foot, the head, the first longitudinal, and the second longitudinal edges, and the foot ramp extends along the first longitudinal edge between the head edge and the foot edge of the foot section. 15. The patient support apparatus of claim 14, wherein the first longitudinal edge defines a first vertical plane, the patient-support apparatus includes a longitudinal axis that defines a second vertical plane that is generally parallel to the first vertical plane, and the foot ramp includes a foot-ramp surface defining a third plane, the third plane intersects the first plane to define a first angle and a second angle, and the first angle and the second angle are complementary to one another. 16.
