A cervical collar comprises front and rear halves for resting on the shoulders and extending around the neck to support the chin and rear of a patient's head. Each half comprises a thin, semi-rigid shell molded from a plastic material such as polyethylene. The front half preferably comprises a self-supporting shell preformed as a single piece of a thin, semi-rigid material shaped to conform to the anatomical contour of the underside of the chin and lower jaw, the front portion of the neck, and the upper chest region. The length of the neck region of the shell is reinforced for increasing its stiffness to resist without collapse the downward forces on the chin and lower jaw-supporting section of the shell normally encountered during use. A resilient open cell containing material provides padding for the inside face of the shell. The rear half of the collar comprises a similar thin semi-rigid shell with an open cell containing material on its inside face. Flexible straps with Velcro fasteners on the rear half are attached to cooperating Velcro fasteners on the neck region of the front half of the collar. In one embodiment, the neck region of the collar is reinforced by an elongated embossed region extending lengthwise across the neck region of the shell for increasing the structural stiffness of the neck region without either increasing the wall thickness of the shell or adding separate reinforcing materials.
