The active backboard can also include multiple layers that can slide or move relative to each other to move the patient relative to the backboard. The active backboard can include roller bars, a wheel, and/or projections to assist with moving a patient relative to the backboard. ## Claims ### Claim 1 A backboard for a mechanical cardiopulmonary resuscitation (CPR) device, comprising: a first elongated portion extending along a first axis from a first connector at a first end to a second end opposite the first end, the first connector being structured to couple to an upper portion of the mechanical CPR device; a second elongated portion adjacent to the first elongated portion, the second elongated portion being slidable relative to a surface of the first elongated portion along a second axis that is perpendicular to the first axis, defining a direction of movement; and a locking mechanism configured to lock the second elongated portion along the second axis relative to the first elongated portion. ### Claim 2 (depends on 1) The backboard of claim 1, wherein the locking mechanism includes a pneumatic mechanism. ### Claim 3 (depends on 1) The backboard of claim 1, wherein the locking mechanism includes a hydraulic mechanism. ### Claim 4 (depends on 1) The backboard of claim 1, wherein the locking mechanism is configured to be engaged by a pushbutton. ### Claim 5 (depends on 1) The backboard of claim 1, wherein the locking mechanism is configured to be engaged by rotating a dial. ### Claim 6 A backboard for a mechanical cardiopulmonary resuscitation (CPR) device, comprising: a first elongated portion extending along a first axis from a first connector at a first end to a second end opposite the first end, the first connector being structured to couple to an upper portion of the mechanical CPR device; and a second elongated portion adjacent to the first elongated portion, the second elongated portion being slidable relative to a surface of the first elongated portion along a second axis that is perpendicular to the first axis, defining a direction of movement; wherein the first elongated portion includes a track, in which the second elongated portion is slidable within the track. ### Claim 7 (depends on 6) The backboard of claim 6, further comprising a locking mechanism configured to lock the second elongated portion along the second axis relative to the first elongated portion, the locking mechanism including a ball bearing configured to prevent movement of the second elongated portion along the track. ### Claim 8 A backboard for a mechanical cardiopulmonary resuscitation (CPR) device, comprising: a first elongated portion extending along a first axis from a first connector at a first end to a second end opposite the first end, the first connector being structured to couple to an upper portion of the mechanical CPR device; and a second elongated portion adjacent to the first elongated portion, the second elongated portion being slidable relative to a surface of the first elongated portion along a second axis that is perpendicular to the first axis, defining a direction of movement; wherein the second elongated portion includes a track, in which the first elongated portion is slidable within the track. ### Claim 9 (depends on 8) The backboard of claim 8, further comprising a locking mechanism configured to lock the first elongated portion along the second axis relative to the second elongated portion, the locking mechanism including a ball bearing configured to prevent movement of the first elongated portion along the track. ### Claim 10 A backboard for a mechanical cardiopulmonary resuscitation (CPR) device, comprising: a first elongated portion extending along a first axis from a first connector at a first end to a second end opposite the first end, the first connector being structured to couple to an upper portion of the mechanical CPR device; and a second elongated portion adjacent to the first elongated portion, the second elongated portion being slidable relative to a surface of the first elongated portion along a second axis that is perpendicular to the first axis, defining a direction of movement; wherein the first elongated portion has a width in the direction of movement that is less than a width of the second elongated portion in the direction of movement. ### Claim 11 A backboard for a mechanical cardiopulmonary resuscitation (CPR) device, comprising: a first elongated portion extending along a first axis from a first connector at a first end to a second end opposite the first end, the first connector being structured to couple to an upper portion of the mechanical CPR device; and a second elongated portion adjacent to the first elongated portion, the second elongated portion being slidable relative to a surface of the first elongated portion along a second axis that is perpendicular to the first axis, defining a direction of movement; wherein the second elongated portion has a width in a direction of movement that is less than a width of the first elongated portion in the direction of movement.
