The neck traction device elongated a user's neck with the application of
force on the user's shoulders. One embodiment includes a head pad, a
vertically movably head support frame, a pivotally connected linkage
member coupled to a shoulder frame element. The shoulder frame and
shoulder pads are longitudinally movably mounted and the linked system
exerts a longitudinal force on the user's shoulders when the user's head
rests on the head pad and depresses the head pad. A biasing mechanism
either upwardly supports the head frame or longitudinally limits the
extension of the shoulder frame such that when the head is lifted off the
head frame, the biasing mechanism raises the head pad and moves back the
shoulder frame and pads. Alternatively, a transmission may be used to
convert the substantially downward force due to the head weight to a
longitudinal force on the shoulder pads.
