Abstract
Abstract This invention relates to a spineboard and parts thereof adapted for securement and transport of a person who may have suffered a spinal injury. The spineboard consists of a board having at least one longitudinal track adapted to receive in slidable connection at least one body harness and having means to secure a head harness; at least one body harness having a pad adapted to lie over the track and having at least one strapping means adapted to engage the track in slidable connection and to encircle and to secure a person to the board; and a head harness adapted to be located on the board.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
343 words
A spineboard comprising: a body supporting board having a length and width adapted to support a prostrate person, said board being fabricated of a molded polyethylene hollow shell having one or more stiffening beams inserted within said hollow shell extending lengthwise therealong with remaining portions of said shell being filled with polyurethane foam, said board having a plurality of sets of longitudinally extending tracks at generally longitudinally spaced positions therealong, each set of tracks comprising a pair of slots through the board, said board also having openings at one end; a head harness comprising a forehead pad and three straps attached to said forehead pad, means for removably securing said straps to said board with each strap being received within a corresponding opening at said one board end; said harness including slip connectors enabling the straps to be pulled and tightened in one direction and to resist slippage in the other direction whereby said harness is adapted to be tightened over and about the head of an individual to limit movement of the head without interfering with the movement of the chin; a plurality of body harnesses each comprising a pad overlying a corresponding set of longitudinal tracks on the board and central portions of said board and a strap, means carried by said pad for slidably receiving said strap along the underside of said pad, said strap extending through a pair of slots of said tracks of the board to permit the strap to slide with said pad longitudinally along the set of tracks to a predetermined longitudinal location along said board while enabling the strap to be secured to the board by means of engagement through the slots of said tracks, each said strap of said body harness having two ends, a hook carried by at least one of said strap ends to snap fit over an edge of the board, each said strap having slidable connectors which permit the strap to be drawn tight in one direction while resisting sliding of the strap through the connector in the reverse direction.
Claim 2
Dependent Claim
343 words
A spineboard comprising: a body supporting board having a length and width adapted to support a prostrate person, said board being fabricated of a molded polyethylene hollow shell having one or more stiffening beams inserted within said hollow shell extending lengthwise therealong with remaining portions of said shell being filled with polyurethane foam, said board having a plurality of sets of longitudinally extending tracks at generally longitudinally spaced positions therealong, each set of tracks comprising a pair of slots through the board, said board also having openings at one end; a head harness comprising a forehead pad and three straps attached to said forehead pad, means for removably securing said straps to said board with each strap being received within a corresponding opening at said one board end; said harness including slip connectors enabling the straps to be pulled and tightened in one direction and to resist slippage in the other direction whereby said harness is adapted to be tightened over and about the head of an individual to limit movement of the head without interfering with the movement of the chin; a plurality of body harnesses each comprising a pad overlying a corresponding set of longitudinal tracks on the board and central portions of said board and a strap, means carried by said pad for slidably receiving said strap along the underside of said pad, said strap extending through a pair of slots of said tracks of the board to permit the strap to slide with said pad longitudinally along the set of tracks to a predetermined longitudinal location along said board while enabling the strap to be secured to the board by means of engagement through the slots of said tracks, each said strap of said body harness having two ends, a hook carried by at least one of said strap ends to snap fit over an edge of the board, each said strap having slidable connectors which permit the strap to be drawn tight in one direction while resisting sliding of the strap through the connector in the reverse direction.
Claim 3
Dependent Claim
15 words
A spineboard as claimed in claim 1 wherein said forehead pad includes an elastic material.
Claim 4
Dependent Claim

A spineboard as claimed in claim 1 wherein said forehead pad has an opening adapted to fit about a portion of a head to be restrained.
Claim 5
Dependent Claim
30 words
A spineboard according to claim 1 wherein each said stiffening beam comprises two layers of carbon fiber fabrics spaced one from the other by a layer of polyvinyl chloride foam.
Claim 6
Dependent Claim
83 words
A spineboard according to claim 1 including a pair of transversely spaced longitudinally extending runners extending along the underside of said spineboard and spaced inwardly from the lateral margins of said spineboard, means defining a plurality of handholds disposed at longitudinally spaced positions along the opposite margins of said spineboard laterally outwardly of said runners, said means defining the handholds lying above the elevation of said runners such that the handholds may be conveniently grasped when the spineboard runners rest on a surface.
Claim 7
Dependent Claim
12 words
A spineboard according to claim 5 wherein said beams overlie said runners.
Claim 8
Dependent Claim
46 words
A spineboard according to claim 6 wherein said spineboard has a lower surface between said runners at an elevation above the elevation of said runners, the straps of said body harness passing through said slots and along said lower surface at an elevation above the runners.
Claim 9
Dependent Claim
108 words
A spineboard comprising: a body supporting board having a length and width adapted to support a prostrate individual, said board being fabricated of a molded polyethylene hollow shell having one or more stiffening beams within said hollow shell and extending lengthwise therealong, with the remaining portions of said shell being filled with polyurethane foam, each of said beams being comprised of two layers of carbon fiber fabrics spaced one from the other by a layer of polyvinyl chloride foam, said board having a plurality of sets of longitudinally extending tracks at generally longitudinally spaced positions therealong, each set of tracks comprising a pair of slots through the board.
Claim 10
Dependent Claim
108 words
A spineboard comprising: a body supporting board having a length and width adapted to support a prostrate individual, said board being fabricated of a molded polyethylene hollow shell having one or more stiffening beams within said hollow shell and extending lengthwise therealong, with the remaining portions of said shell being filled with polyurethane foam, each of said beams being comprised of two layers of carbon fiber fabrics spaced one from the other by a layer of polyvinyl chloride foam, said board having a plurality of sets of longitudinally extending tracks at generally longitudinally spaced positions therealong, each set of tracks comprising a pair of slots through the board.
