Proning frame for a patient bed

A head rest accessory for coupling to sockets provided on a bed frame of a hospital bed adjacent a head end of the hospital bed, the head rest accessory comprising

• a frame having a pair of rails that are spaced apart and substantially parallel and that extend from a distal end to a proximal end, a crossbeam coupled to the distal ends of the pair of rails, a pair of posts that are coupled to the proximal ends of a respective rail of the pair of rails, each post extending from the proximal ends to permit the posts to be insertable downwardly into the sockets to couple the frame to the bed frame of the hospital bed so that the frame is cantilevered from the bed frame,
• a head rest mount coupled to the frame and extending between the pair of rails, the head rest mount having at least one releasable clamp that grips a corresponding one of the pair of rails to lock the head rest mount in place on the frame when the releasable clamp is in a locked condition, and the head rest mount being repositionable along the pair of rails when the releasable clamp is in an unlocked condition, and
• a head rest coupled to the head rest mount, the head rest including a face rest shell having an upwardly facing concave surface and having a generally T-shaped cutout to receive a patient's eyes, nose, mouth, and a central chin region of the patient's face when the patient is in a prone position on the head rest accessory.
