Surgical table including adjustable headrest

An adjustable headrest for a surgical table, comprising:

• an attachment member configured to be releasably mounted to the surgical table;
• a frame having a proximal end and a distal end, the proximal end being mounted for pivotable movement relative to the attachment member to raise and lower the distal end relative to the attachment member;
• a head support plate mounted for pivotable movement relative to the frame to tilt the head support plate relative to the frame;
• a lock-unlock actuator including a linearly displaceable bar and a user handle, the linearly displaceable bar being supported and slidably guided by the frame for translating movement between a first position and a second position and being spring biased to move from the second position to the first position, the user handle being configured to move the linearly displaceable bar against the spring bias force from the first position to the second position;
• wherein in the first position the linearly displaceable bar is configured to lock the frame pivotably against lowering of the distal end of the frame relative to the attachment member and to lock the head support plate pivotably relative to the frame, and wherein in the second position the linearly displaceable bar is configured to unlock the frame pivotably relative to the attachment member to allow lowering of the distal end of the frame relative to the attachment member and to unlock the head support plate pivotably relative to the frame.
