Cervical extrication collar
First Claim
1. A cervical collar adapted for being sized on or off the patient and being efficiently and properly applied to the neck of a patient under emergency or non-emergency conditions, and comprisingan elongate generally flat band having a sufficient longitudinal length and flexibility to encircle a patient'"'"'s neck in use, and including an upper edge and a lower edge and so as to define a vertical direction extending between the upper edge and the lower edge,a chin support member,means joining the chin support member along the upper edge of said band, and comprising a post fixed to said chin support member so as to extend downwardly therefrom, and means slidably interconnecting the post and the band so as to permit relative sliding movement in either vertical direction and which includes a locking arm pivotally mounted to one of the post and the band so as to be manually pivotable between a release position wherein the post is freely slidable relative to the band in either vertical direction to permit upward and downward movement of the chin support member, and a locking position wherein the post and the band are tightly pressed against each other to preclude relative sliding movement between the post and the band, andfastening means mounted to said band for releasably securing said band in encircling relation about the neck of a patient.

Abstract
An emergency extrication collar comprising a flexible band for encircling the wearer'"'"'s neck, a chin support member which may be readily adjusted in elevation with respect to the band so as to permit adjustment to fit patients having varying neck sizes. The chin support member is connected to the band by a post which is slidably connected to a vertical strap on the band, and such that the elevation of the chin support member above the post, and thus the neck size of the collar, may be adjusted by simply sliding the post and chin support upwardly to any selected size between the size extremes. A pawl and ratchet interconnection between the post and strap precludes movement in the opposite direction. The collar is secured in its adjusted size by a locking arm which is pivotally mounted on the post, and movement of the locking arm to its release position also releases the pawl and ratchet interconnection.

8. A cervical collar adapted for being sized on or off the patient and being efficiently and properly applied to the neck of a patient under emergency or non-emergency conditions, and comprising
an elongate generally flat band having a sufficient longitudinal length and flexibility to encircle a patient'"'"'s neck in use, and including an upper edge and a lower edge and so as to define a vertical direction extending between the upper edge and the lower edge, a chin support member, means joining the chin support member along the upper edge of said band, and comprising (a) a central opening formed in said band, (b) a vertical strap formed on said band so as to extend vertically across said opening, and with said strap including a generally flat inner surface, (c) a post fixed to said chin support member so as to extend downwardly therefrom, and with said post including an generally flat outer surface and a pair of longitudinally spaced apart wings extending upwardly from said outer surface, and (d) means interconnecting the post and the strap with said inner surface of said strap overlying said outer surface of said post and with said strap lying between said wings of said post, and so as to permit relative vertical sliding movement between the post and the strap, said interconnecting means including a locking arm pivotally mounted between said wings so as to overlie the strap and so as to be pivotable about a longitudinal pivot axis between a release position wherein the post is freely slidable along said strap to permit upward and downward adjustment of the chin support member, and a locking position wherein said strap is tightly pressed against the post to preclude relative sliding movement between the post and the strap, and fastening means mounted to said band for releasably securing said band in encircling relation about the neck of a patient.

19. A cervical collar adapted for being sized on or off the patient and being efficiently and properly applied to the neck of a patient under emergency or non-emergency conditions, and comprising
an elongate generally flat band having a sufficient longitudinal length and flexibility to encircle a patient'"'"'s neck in use, and including an upper edge and a lower edge and so as to define a vertical direction extending between the upper edge and the lower edge, a chin support member, means joining the chin support member along the upper edge of said band, and comprising (a) a central opening formed in said band, (b) a vertical strap formed on said band so as to extend vertically across said opening, (c) a post fixed to said chin support member so as to extend downwardly therefrom, and (d) means slidably interconnecting the post and the strap and which includes a pawl and ratchet interconnection between the post and the strap which permits sliding movement of the post in the upward vertical direction while precluding sliding movement in the opposite direction, and means for selectively releasing the pawl and ratchet interconnection so as to permit slidable movement of the post along the strap in either direction, and fastening means mounted to said band for releasably securing said band in encircling relation about the neck of a patient.
