Cervical collar having height and circumferential adjustment

1. A cervical collar comprising:

an anterior main support piece having a proximal support portion and a removable height adjustment mechanism lockable at a plurality of locations on the anterior main support piece, wherein the main support piece includes first and second spaced depending projections that are selectively received within corresponding first and second proximally extending upright leg portions on the removable height adjustment mechanism.

2. The cervical collar according to claim 1 , further comprising:

a posterior main support piece having a proximal support portion and a circumferential adjustment mechanism including at least a strap portion formed in a side extending portion of the posterior main support piece.

3. The cervical collar according to claim 2 , wherein the anterior and posterior main support piece each have flexible or resilient edges formed thereon.

4. The cervical collar according to claim 3 , wherein the flexible or resilient edges are overmolded along a periphery of the respective anterior and posterior main support piece.

5. The cervical collar according to claim 3 , wherein the anterior and posterior proximal support portions are contiguously formed with the respective resilient edges of the anterior and posterior main support pieces.

6. The cervical collar according to claim 2 , wherein the posterior main support piece includes a distal support portion.

7. The cervical collar according to claim 6 , wherein the posterior distal support portion is a flexible or resilient, overmolded portion.

8. The cervical collar according to claim 6 , wherein the posterior distal support portion is an anatomically configured three-dimensional support portion.

9. The cervical collar according to claim 2 , wherein the strap portion is a flexible or resilient, overmolded portion.

10. The cervical collar according to claim 2 , wherein the anterior and posterior proximal support portions are anatomically configured three-dimensional support portions.

11. The cervical collar according to claim 2 , wherein the anterior and posterior proximal support portions are flexible or resilient, overmolded portions.

12. The cervical collar according to claim 2 , wherein the anterior and posterior main support pieces include a plurality of slots formed therein to provide ventilation and resiliency to the anterior and posterior main support pieces.

13. The cervical collar according to claim 2 , further comprising indicia formed on at least one of the anterior and posterior main support pieces for orienting the anterior and posterior main support pieces.

14. The cervical collar according to claim 2 , further comprising:

fold lines formed in each of the anterior and posterior main support pieces.

15. The cervical collar according to claim 1 , wherein the height adjustment mechanism comprises:

the first and second upright leg portions formed together with a flared distal end;

a locking button pivotally connected to each of the first and second upright leg portions for selectively engaging locking projections formed on the first and second depending projections of the anterior main support piece; and

a footpad on the flared distal end.

16. The cervical collar according to claim 1 , further comprising height adjustment indicia provided on the first and second depending projections cooperating with the removable height adjustment mechanism to indicate a current size of the cervical collar.

17. The cervical collar according to claim 1 , wherein a thickened support section runs along the anterior main support piece from a first end of the first depending projection to a first end of the second depending projection.

18. The cervical collar according claim to 1 , further comprising:

at least one locking button provided in one of the first and second upright leg portions for selective engagement with locking projections formed on the respective first or second depending projection; and

wherein when the locking button is in a disengaged, unlocked position, the height adjustment mechanism can be moved in both the proximal and distal directions, and when the locking button is in an engaged, locked position, the height adjustment mechanism can be moved in the distal direction only.

19. A cervical collar comprising:

an anterior main support piece having a proximal support portion and a removable height adjustment mechanism, wherein the main support piece includes first and second spaced depending projections that are selectively received within corresponding first and second upright leg portions on the removable height adjustment mechanism;

wherein the anterior main support piece is formed from a main support piece and a flexible edges extending about a substantial portion of the periphery of the main support piece, the flexible edges being more flexible than the main support piece.

20. A cervical collar comprising:

an anterior main support piece having a proximal support portion and a removable height adjustment mechanism, wherein the main support piece includes first and second spaced depending projections that are selectively received within corresponding first and second upright leg portions on the removable height adjustment mechanism;

at least one locking button provided in one of the first and second upright leg portions for selective engagement with locking projections formed on the respective first or second depending projection; and

wherein when the locking button is in a disengaged, unlocked position, the height adjustment mechanism can be moved in both the proximal and distal directions, and when the locking button is in an engaged, locked position, the height adjustment mechanism can be moved in the distal direction only.
