A patient support apparatus comprising a central panel section (120a-120d), a side panel section (122a-122d, 123a-123d) movable relative to the central panel section (120a-120d) between a retracted position and an extended position and an adjusting system for moving the side panel section (122a-122d, 123a-123d) relative to the central panel section (120a-120d) between the retracted position and the extended position, wherein the adjusting system comprises: a mounting bracket mounted to the side panel section (122a-122d, 123a-123d); a handle assembly rotatably mounted to the mounting bracket, the handle assembly comprising a outer end allowing a user to manually operate the adjusting system and first end rotatably mounted to the mounting bracket; an extending member comprising a first end operatively couplable to the central panel section (120a-120d) of the patient support apparatus and a second end rotatably mounted to the mounting bracket, the extending member being capable of extending and retracting along a longitudinal axis; characterized by a clutch assembly (222, 402) operatively mounted to the mounting bracket, the clutch assembly (222, 402) operatively engaging the first end of the handle assembly and the second end of the extending member, wherein the clutch assembly (222, 402) is configured to urge a movement of the extending member upon actuation of the handle assembly below a defined resistance level of the extending member while preventing rotation of the extending member above or equal to the defined resistance level of the extending member, wherein the rotation of the extending member in a first rotation direction causes the side panel section (122a-122d, 123a-123d) to move toward the extended position relative to the central panel section (120a-120d) while the rotation of the extending member in an opposed rotation direction causes the side panel section (122a-122d, 123a-123d) to move toward the retracted position. a mounting bracket mounted to the side panel section (122a-122d, 123a-123d); a handle assembly rotatably mounted to the mounting bracket, the handle assembly comprising a outer end allowing a user to manually operate the adjusting system and first end rotatably mounted to the mounting bracket; an extending member comprising a first end operatively couplable to the central panel section (120a-120d) of the patient support apparatus and a second end rotatably mounted to the mounting bracket, the extending member being capable of extending and retracting along a longitudinal axis; characterized by a clutch assembly (222, 402) operatively mounted to the mounting bracket, the clutch assembly (222, 402) operatively engaging the first end of the handle assembly and the second end of the extending member, wherein the clutch assembly (222, 402) is configured to urge a movement of the extending member upon actuation of the handle assembly below a defined resistance level of the extending member while preventing rotation of the extending member above or equal to the defined resistance level of the extending member, wherein the rotation of the extending member in a first rotation direction causes the side panel section (122a-122d, 123a-123d) to move toward the extended position relative to the central panel section (120a-120d) while the rotation of the extending member in an opposed rotation direction causes the side panel section (122a-122d, 123a-123d) to move toward the retracted position.
