A collapsible cervical collar (1) is disclosed with an elongated neck encircling band (2) and a chin support brace (3). The chin support brace (3) has first (26) and second (27) ends and a concave edge (28) separating the first (26) and second (27) ends. A hinge (29) connects the elongated neck encircling band (2) to the chin support brace (3). The hinge (29) enables the chin support brace (3) to rotate more than 180 degrees relative to the elongate neck encircling band (2) from an inoperable or flat condition to an operable three-dimensional condition.
