Abstract
A cervical collar including front and back halves adapted to fit around the neck, and an adjustable strap for releasably securing the halves in position on the neck. The halves of the collar are made from a laminate having outer layers of a foamed polymeric material and an inner layer of a solid, non-foamed thermoplastic material. The foam layes provide padding and comfort, and the solid layers provide rigidity and support to immobilize the head and neck. In one embodiment there is provided a large hole in the front most portion of the collar to accommodate the Adam's apple. In another embodiment, the strap is attached to the back half by looping it through parallel slots formed in the rearmost portion of the collar which are narrower than the width of the strap adjacent the slots, and attached to the front half by stitching at the ends thereof.
