Adjustable body positioning device

Abstract

A resilient body for supporting in elevated condition the knees of a person lying on a horizontal surface comprises a pair of limbs joined by a reduced thickness neck which facilitates the rocking of the limbs between positions in which the limbs extend in opposite directions from the neck to a selected one of a number of adjusted positions in which the limbs confront one another and form an upstanding arch for supporting the person's knees in an elevated condition.

1 . A positioning device comprising a body member formed of resiliently flexible material and having two limbs joined to one another by a neck, said neck being thinner than said limbs, thereby facilitating rocking of said limbs at said neck between extreme positions in one of which said limbs extend in opposite directions from said neck and in another of which said limbs confront one another; and adjustable coupling means releasably coupling said limbs to one another for restraining relative movement of said limbs in a direction toward said one position from said another position. 
   
   
       2 . The device according to  claim 1  wherein said coupling means comprises a strap extending from one of said limbs to the other of said limbs. 
   
   
       3 . The device according to  claim 1  wherein said coupling means comprises a cord extending from one of said limbs to the other of said limbs. 
   
   
       4 . The device according to  claim 3  wherein each of said limbs has passages in which said cord is slideably accommodated. 
   
   
       5 . The device according to  claim 4  including a clasp in which said cord adjustably is accommodated. 
   
   
       6 . The device according to  claim 1  wherein said coupling means comprises a strap accommodated in grooves formed in each of said limbs. 
   
   
       7 . The device according to  claim 6  wherein said strap and said grooves have cooperable releasable fasteners for releasably securing said strap in a selected one of a number of adjusted positions. 
   
   
       8 . The device according to  claim 1  wherein said coupling means comprises a strap spanning and removably secured to said limbs. 
   
   
       9 . The device according to  claim 8  wherein said strap is inelastic. 
   
   
       10 . The device according to  claim 1  wherein said coupling means comprises anchor strap means secured to said limbs and a restraining strap extending between said limbs and joined to said anchor strap means. 
   
   
       11 . The device according to  claim 10  wherein said anchor strap means comprises a pair of retaining straps on opposite sides of said neck and wherein said retaining strap extends from one of said restraining straps beneath both of said limbs, said restraining strap being secured adjacent its opposite ends to both of said retaining straps.
