The sheet 44 is provided externally thereof with a plu rality of male snap fasteners 48 and which are shown as three in number at each side of the center of the unit but which maybe of a greater or less number,
The assembled cervical collar is illustrated in Figs. 8 and 9 and wherein the unit 11 is adjustably secured to unit 10 by snap engagement of the fastener 22 on each buckle 21 with a corresponding fastener 43 on the unit 11. The buckles 2i and fasteners 43 provide for a wide range of radial adjustment of the collar since the buckles improved cervical collar in accordance with the present invention is a three-piece structure, two of which are embodied in one unit which is pivotally and adjustably secured to the other single piece unit and that the two piece unit is vertically adjustable while the two units are radially adjustable thereby providing a structure which is readily adaptable for different thickness necks and which by the vertical adjustment of the two piece unit provides for any condition for head support to take the load oil the neck muscles.
By the provision of the two units it) and 11 the head is supported both at the back and the front and any degree of hyperextension can be eiiected by vertical adjustment of the two sections 12 and 13 of the unit ll).
Furthermore, the collar is capable of adjustment whereby the head of awearer is maintained level with neither flexion or hyper-extension.
The modified form of unit 1 9? illustrated in Figs. ll and 12 differs from that of Figs. 1 and 3 mainly in that section 13 overlaps section 12 whereas in Figs. 1 and 3 section 13 underlaps section 12. Sections 12 and 13 have a single vertical adjustment connection which comprises an elongated slot 32 in section 12 and a rivet 33 supported by section 13 and whose shank extends through the slot 32 in this modified embodiment the opposite ends of sections 12 and 13 are free of each other. in this embodiment the straps 28 are not unitary with either section but same are constituted by the opposite ends of a strip Si; which is of the same material as the sheets we and 28 and which extends lengthwise of the unit tially intermediate the upper and lower cushion cor and 2%. The strip 5 5 is disposed between the sheet and the adjusting elements 36, 39 and the opposite ends thereof are adjustably connected to sheet 28 by the following means, sheet 2d is provided .i generally vertical slot 51 adjacent each end thereof and the strip 5% is provided with a rivet 52 adjacent each end thereof whose shank extends through the respective slot 51. The slots as shown however slightly converge upwardly and in order to provide for movement of the rivet shanks in the slots the strip is provided with a relatively short, generally horizontal slot 53 adjacent each end in which the rivet shanks can move.
An application of the improved cervical collar is illustrated in Fig. 10 adjusted for hyperextension.
The preferred structural embodiment of the invention as disclosed in Figs. 13, 14 and 15 is of the same general character as that disclosed in Figs. 1 to 8 but diifers therefrom in a modified embodiment of the unit 10 and which modified unit itl is adapted for cooperation with the unit 11 of Figs. 1 to 8.
The modified unit 10 comprises a pair of vertically opposed upper and lower sections 12 and 13 respectively which embody upper and lower sheets 14 and 28 whose upper and lower edges are provided with resilient cores 17 and 2 respectively having covers 16 and respectively whose edges are stitched to the adjacent edges of the sheets in the manner above disclosed in connection with Figs. 1 to 8. Straps 25) project from opposite ends of sheet 14 and same are provided with buckles 21. The sheets 14* and 28 do not however overlap at their inner edges as in the embodiments of Figs. 1 and 11 but are vertically aligned as indicated in Fig. 14 with their adjacent inner edges in vertically aligned non-lapping relation and which edges may abut or be in variably vertically spaced relation in the relative adjustments thereof.
The sections 12 and 13 are adjustably connected by the means 36 to 42 as in the previously described embodiments. The unit 10* further comprises a relatively wide backing sheet 66 which laps the joint between sheets 14 and 28 and whose opposite ends are movably connected to the opposite ends of sheets 14 and 28 by means of rivets 61 whose shanks freely float in vertical slots 62 in opposite ends of sheet and generally horizontal slots 63 in the opposite ends of sheets 14* and 28 The preferred structure of Figs. l3, l4 and 15 functions similarly to the embodiments of Figs. 1 to 9 and Figs. 11 and 12 and in all forms it is to be particularly observed that the cervical collar is reversible in use since the same may be worn as in Fig. 10 for hyperextension wherein the unit 10, 10 or 10 is disposed beneath the chin or for fiexion wherein the unit 11 is disposed beneath the chin.
Furthermore, the improved collar in all embodiments thereof is radially adjustable and the unit 10, 10 or 10* which may be disposed under the chin or at the back of the neck, is vertically adjustable whereby any and all conditions are capable of being substantially satisfied by the improved collar in any of the several embodiments thereof herein disclosed.

A cervical collar comprising a pair of diametrically opposed units, one of said units being provided with a strap projecting from each end thereof and being provided with an element of a snap fastener and the other unit being provided with a plurality of spaced cooperating snap fastener elements selectively engageable with the fastener element on each buckle whereby the diameter of the collar is capable of adjustment through a relatively large range.
2. In a cervical collar comprising a pair of diametrically opposed units, one of said units comprising a pair of upper and lower sections adjustable with respect to each other and having adjacent portions thereof in overlapped relation, means securing said overlapped portions for vertical adjustment of the sections, and means engaged with said sections for locking same in any vertically adjusted position, said means comprising a pair of elements each including an elongated member having one end thereof connected to one of said sections, a second elongated member having one end thereof connected to the other section, said first member having its opposite edges turned over and providing a pair of channels in which said second member is slidably disposed, said first member being provided with an elongated slot intermediate said channels, and a screw whose threaded shank extends through said slot and is adjustably threaded in a tapped opening in said screw member and the other of said units being formed of a section of relatively greater width than either the upper or the lower section of the first unit.
3. In a cervical collar, comprising a pair of diametrically opposed units, one unit comprising a pair of upper and lower sections having opposed abutting edges, a protector sheet disposed beneath said sections in lapping relation to the joint between same, means for vertically adjusting said sections, means connecting said protector sheet to said sections while providing for adjustment thereof, and a flexible connection between each unit to provide for adjustment of the diameter of the collar.
4. In a reversible cervical collar, a pair of diametrically opposed curved units one unit comprising a pair of upper and lower sections having vertically aligned spaced edges, and means for adjusting said sections to thereby vary the spacing between said edges, said other unit being in one section, whereby each unit is diametrically reversible for providing hyperextension in one position thereof and flexion in the opposite reverse position thereof.
5. A reversible cervical collar comprising a pair of diametrically opposed units of relatively different widths, one unit being adjustable to vary the width thereof, and flexible means projecting from each end of said first unit for adjustably and flexibly connecting with means carried by each end of the other of said units to join said units together, whereby the diameter of the collar is capable of adjustment.
6. A reversible cervical collar comprising a pair of diametrically opposed units, one of said units being provided with a strap projecting from each end thereof and being provided with an element of a fastener means and the other unit being provided with an element of said fastener means for adjustable engagement of each respective element of each unit, whereby the diameter of the collar is capable of adjustment to the neck of the wearer.
7. A cervical collar for encircling a wearers neck comprising diametrically opposed units, one unit comprising a pair of upper and lower sections having aligned spaced edges, means for adjusting said sections of the first unit, to thereby vary the spacing between said edges and the overall width of said unit, said first unit being reversible with respect to said other unit of said pair for providing hyperextension in one position thereof and flexion in the opposite reversed position thereof.
8. The cervical collar described in claim 7, wherein the said alined spaced edges are maintained out of contact with the neck skin by a protective backing sheet.
