Abstract
A recumbent head support system serving as a sleep pillow alternative comprising a frame which suspends a fabric platform and allows the user to customize a height level of support without having to lift their head off the support. In one embodiment, the headrest suspension frame includes a base cross support member, a pair of lower horizontal base members secured to base cross support member, a pair of vertical members secured to base cross member or horizontal base members, and an upper pair of rotatable horizontal members secured to upper terminal ends of fore-end vertical members and arced vertical members which connect upper and lower horizontals, and a fabric sling attached to upper rotatable horizontal members.

DETAILED DESCRIPTION
(4) At the outset, it should be appreciated that like drawing numbers on different drawing views identify identical, or functionally similar, structural elements. It is to be understood that the claims are not limited to the disclosed aspects. Furthermore, it is understood that this disclosure is not limited to the particular methodology, materials and modifications described and as such may, of course, vary. It is also understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to limit the scope of the claims. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this disclosure pertains. It should be understood that any methods, devices or materials similar or equivalent to those described herein can be used in the practice or testing of the example embodiments.
(5) It should be appreciated that the term “substantially” is synonymous with terms such as “nearly,” “very nearly,” “about,” “approximately,” “around,” “bordering on,” “close to,” “essentially,” “in the neighborhood of,” “in the vicinity of,” etc., and such terms may be used interchangeably as appearing in the specification and claims.

(7) The frame system 11a includes horizontal upper members 2, 2, which may be tubes, solid rods, or any other suitable member. Longitudinally extending horizontal upper frame members 2, 2 each have two ends, one fore-end engaging a first or upper end of vertical frame members 3, 3. The longitudinal horizontal upper frame members 2, 2, extend slightly pitched downward from the upper portions of vertical frame members 3, 3. Vertical frame members 3, 3 have second or tower ends arranged distally in relation to the first upper ends. Vertical frame members 3, 3 may be tubes, solid rods, or any other suitable member. Vertical frame members 3, 3 have second or lower ends that are secured to first cross base frame support member 4 or in another embodiment not shown, 3, 3 may be secured to first horizontal base members 5, 5 proximal to cross base support 4. Cross base support 4 and vertical frame elements 3, 3 are generally co-planar. Cross support frame member 4 has two ends that are respectively secured to lower horizontal base frame members 5, 5 at the first or fore ends of horizontal base frame members 5, 5.
(8) The opposite terminal ends of the horizontal upper frame members 2, 2 (that is, at the longitudinal extremity of members 2, 2) and the longitudinal terminal ends or second ends of horizontal base lower frame members 5, 5 engage the opposite ends of arced vertical connecting members 1b, 1b. In other words, arced vertical connecting members 1b, 1b provide a vertical supporting framework at a distal, longitudinal end of the upper rotatable horizontal frame members 2, 2, because the distal connecting members 1b, 1b are coupled to the upper and the lower horizontal frame members. Arced vertical connecting members 1b, 1b may be tubes, solid rods, or any other suitable member that does not have defined edges about its outside perimeter and are preferably configured in an arc shape as to prevent having defined edges that could injure an individual using sling headrest suspension system 10.
(9) Rotatable control connectors 20, 20 connect upper horizontal frame members 2, 2 to the upper terminal end of vertical frame members 3, 3.
(10) Sling or bridge fabric 6 is arranged to allow a user's head to rest on the sling fabric platform. Sling fabric 6 may include loops or channels 6a arranged at opposite ends of sling 6. Loops or channels 6a are arranged to accept upper longitudinally extending horizontal members 2, 2. When sling fabric 6 is engaged on horizontal upper frame members 2, 2, it creates a suspended fabric platform which may be substantially flat or adjusted to varying levels of droop or concavity 6b down to the base level. Sling depression 6b or the concave sling fabric or, if the sling is disposed in a substantially flat condition, supports a user's head when sling headrest suspension system 10 is in use. When the user's head is on the fabric and in operational use, some concavity will be established. The laxity or degree of concave sling depression 6b of sling fabric 6 may be increased or decreased in depth by the adjustment of control elements 20 and 1a.
(11) In this embodiment of sling headrest suspension system 10, the base cross support member 4 may be fixed or expandable to permit lateral adjustment 50.
(12)
(13) Certain control elements are discussed herein. At the terminal end of upper opposing frame elements 2, 2, a controllable element 1a, 1a enables the user to adjust the tension and hence the droop, depth or concave size of the sling fabric or material 6 (otherwise referred to as the laxity of the fabric) by either rotating the control in the direction of arrow 61a or 61b to either tighten or reduce the droop/concave condition of the sling fabric or to loosen or increase the concavity of the sling fabric, depending on whether the attached sling is rolled over or under the upper horizontal member. In other words, a clockwise or counterclockwise rotation may cause the same effect depending on if the rotation was initiated with an over- or under-hung turn relative to the horizontal member.
(14) A variety of rotational “fabric gathering and fabric loosening” controls may be used. These rotational roll controls permit the user to increase or decrease the slack, laxity and suspension of the bridge—like suspended sling fabric. This roll function, in turn, serves to increase or decrease the support height, weight-bearing surface area of support, that is, the load distribution on the sling, and shifting of pressure point.
(15) The lateral span of the upper frame members or elements (in the y direction) is also adjustable. Each cross-member frame element 4, 4a may have control elements to telescopically collapse or expand the lateral span of the system. One type of control element is a spring-loaded button lock which, when the button is placed in laterally displaced holes, the telescopically configured frame elements 4, 4a enable the user to select the proper lateral span 50 of the system. The user presses the button down, releasing the spring-loaded button from the first hole, then moves the telescopic tubes relative to each other such that the button snaps into the next selected y positional hole. Other telescopic, releasable and locking systems can be used such a cam-driven twist close, twist open lock.
(16) In a further modification, the fore-end vertical frame members 3, 3 need not be straight nor disposed in a singular vertical plane.
(17) One consideration for a stow-away position is the detachment of the cross support member(s).
