The side impact absorbing pad 110 mitigates injury of a patient contacting the side rail 106. The preferred embodiment further includes a patient access flap 112, (of FIG. 12) secured to the side impact absorbing pad 110 and attached to the mattress 108, and a patient head entrapment impediment 114 (of FIG. 4), secured to the side impact absorbing pad 110, and the mattress 108. The patient head entrapment impediment 114 mitigates entrapment of the patient's head between a headboard 116 (of FIG. 4), and the side rail 106 (of FIG. 4), while the patient access flap 112, promotes easy ingress and egress of the patient onto and off of the mattress 108.
FIG. 2 shows the preferred embodiment further includes a head impact absorption pad 118, supported by the mattress 108, in contact adjacency with the headboard 116, and disposed between the side impact absorption pads 110. The head impact absorption pad 118, mitigates injury of the patient head contacting the head board 116. FIG. 2 further shows a footboard 119, distal from the headboard 116, and disposed between the side impact absorbing pads 110.
FIG. 3 of a preferred embodiment of the patient protective system 100, for an adjustable bed 102 shows a better perspective of the relative position of the headboard 116, to the side impact absorptions pads 110, the head impact absorption pad 118, and the side rail 106, hue FIG. 5 shows the side impact absorption pads 110, maintain their position relative to the side rails 106, when the foot portion of the adjustable bed 102 is raised.
FIG. 6 of a preferred embodiment of the patient protective system 100, for an adjustable bed 102 shows that the side impact absorption pads 110, maintain their position relative to the side rails 106, when the head portion of the adjustable bed 102 is raised.
