Abstract
The subject apparatus comprises straps which conform snugly to the user's shoulders to limit headward motion of the user in a direction essentially parallel to the user's spine and support structure with which the user's back is in contact. One end of each strap is attached to the support structure essentially at the point of tangency of the user's shoulder with the support structure. The other end of each strap is pivotally connected to one end of one of a pair of structural arms the other ends of which are pivotally connected to the support structure some distance in the headward direction from the points of attachment of the straps to the structure. When the apparatus is engaged by a user the straps wrap around the user's shoulders from back to front and the arms are at an acute angle to the support surface with one of their ends near the front portions of the user's shoulders and the other ends at their points of attachment to the support structure. With this configuration the apparatus conforms to a variety of sizes and shapes of shoulders without adjustment and use requires no buckling or unbuckling.
