Patent ID: 8038635

Claim:
A forward head position correction collar comprising in combination: a) a shoulder collar assembly; b) a chin-mastoid piece for engaging and positioning the head of a wearer of the collar; c) means interconnecting said chin-mastoid piece to said shoulder collar assembly for manually and incrementally adjusting said chin-mastoid piece with respect to said shoulder collar assembly in an anterior/posterior (Z-axis) direction along the Z-axis; and said means further interconnecting said chin-mastoid piece to said shoulder collar assembly to displace said chin mastoid piece in a vertical direction with respect to said shoulder collar assembly simultaneously with and proportional to the incremental adjustment of said chin piece along said Z-axis ; the said vertical displacement of said chin-mastoid piece with respect to said shoulder assembly and which is proportional to the Z-axis displacement for said chin support piece being that yielded by a point moving at a 5-25 degree slope with respect to the Z-axis; said means interconnecting said chin-mastoid piece to said shoulder collar assembly comprising a track affixed to said chin mastoid piece which is disposed at a slope having a vertical to horizontal rate of change corresponding to the said vertical and horizontal displacement of said chin mastoid piece with respect to said shoulder assembly and a pinion gear engaged with teeth in said track, and means for displacing said chin mastoid piece with respect to said shoulder assembly in accordance with the rotational position of said pinion gear; whereby to adjust the supported head of the wearer from the forward head position to an increasingly corrected position; and d) further including a lordosis correction assembly secured to the rear of said collar and engageable with the rear of the wearer for applying corrective forces by enabling increased pressure to be brought against specified vertebrae; said assembly comprising a plurality of separate, adjoining units, each having an advanceable surface which can be individually advanced against a selected of said vertebrae from the posterior of the vertabrae.
