DETAILED DESCRIPTION OF THE INVENTION

[0020] As seen in FIG. 1, the sling 10 of the present invention includes a base garment or base 5 such as a sleeveless vest which includes a back portion (not shown) joined to a right front side 12 and a left front side 14. The base includes a right arm hole 16 and a left arm hole 18 and an opening 20 for the head and neck of the wearer. Optimally, the right front portion 12 and the left front portion 14 are each joined, such as by sewn shoulder seams 22 or refastenable snaps or hook and loop, to the top of the back portion, and to each other by closure means, such as a zipper, ties, buttons, hook and eyes, snaps, or hook and loop closures. An advantageous neck-opening is a deep V which is cut away from the soft tissue of the neck, which directs the weight of the supported arm away from the neck and cervical spine and onto the upper torso.

[0021] There is an arm holder 6 formed in or attached to the vest 5. In this configuration of the sling 10, the vest 6 the arm holder 6 comprises an interior support 30 or hammock attached at either longitudinal end to the front and back through holes 34 in the vest. This interior support 30 supports the weight of the forearm and also aids in directing this weight into the base of the vest such that the weight is supported at the chest and even through the back of the vest. At least one side, and preferably both sides of the vest includes the arm holder to allow for use for either of the right side and the left side.

[0022] In addition, the vest 5 includes a restraint 3, which helps to secure the forearm within the interior support 30 and to keep it from backing out. The restraint 3 is adjustable in length and height to permit variations in size and in the positioning of the arm relative in and out of the interior support. This adjustability is accomplished by providing a set of hook and loop fasteners on at least one end of the restraint and also on the exterior of the vest 5 so that it can be positioned to allow for a tighter or higher loop as is comfortable and secure.

[0023] The arm holder preferably allows for various positions of the arm. In a first position, the vest includes front and back through holes that allow the forearm to be inserted with the upper arm hanging in line with the torso (i.e., with the axis of the humerus aligned to the coronal plane +/5, and the forearm at an angle of 90+/15, and preferably +/5 to the humeral axis.

[0024] In addition, the sling of the present invention is provided with a forearm support assembly 40 that allows for the forearm to be position at an offset to the body. Specifically, the support assembly 40 includes a firm, but cushiony block 8 configured to support the forearm, and specifically has a length of 10 to 15 inches, and preferably 8 to 10 inches; a width of 3 to 5 inches, and preferably of from 3 to 5 inches; and a height of from 3 to 8 inches, with a cross section of a trapezoid having a top surface 42 that forms an angle of from 30 to 85, and preferably 60+/10, with the back side 44 of the block 8. The block 8 can be rectilinear or can include a curved surface on the backside 44 so as to accommodate the rounded shape of the torso.

[0025] The back side 44 of the block which is the taller side of the block, includes means 9 to fasten the block to the outside of the vest 5, where cooperating hook and loop is optimal since it allows for adjustment of the placement of the block. Optimally, the vest 5 includes mating hook and loop fasteners 2 and a superior flap 1 that has interior hook and loop such that it is secured to the vest 5 hook and loop if the forearm support assembly 40 is not used, and to an axillary sling member 7 if it is used. In this case, the sling member 7 is supported by the flap 1 on one side, and by the vest 5 hook and loop on the other. 1. The superior flap 1 is attached to the vest 5 just at its top. A hook section of the hook and loop is positioned underneath it. FIG. 6 shows a cross-section of the sling with the block 8 in position where the flap 1 is attached to the vest at the top and underneath has the hook section of the hook and loop fastener that grabs the abduction pillow or block of the foam 8. A section of hook and loop 2 on the outside of the vest 5 which is the attachment area for the block 8 secures the mating hook and loop on the inside surface of the flap 1 when the block 8 is not in use.

[0026] As shown in FIG. 7, an additional block 10 can be added to the design to lift the arm further into abduction. In this case, the second block 10 has a bottom surface 50 corresponds in shape and angle to the top surface 42 of the first forearm block 8 and a side surface 54 that abuts the front surface 42 of the first forearm block 8 so that the second block 10 is fully supported, and the bottom surface 50 of the second block 10 has hook and loop fasteners 52 that mate with hook and loop fasteners 51 on the top surface 42 of the first forearm block 8. In this configuration, the forearm rest on the top surface 56 of the second block 10.

[0027] The vest garment of the present invention is preferably made of a material that allows the passage of air and moisture, which is comfortable to wear over time, and which has a certain amount of elastic give to lend resilience to the supportive nature of the sling, such as a mesh fabric which may include Lycra or spandex and include cotton or polyester. The foam blocks are a firm foam having a cushioning surface, such as memory foam. These materials can be adjusted to provide a price point, and recycled materials can be used.

[0028] The sling 10 of the present invention can be used in several different ways. The first shown in FIG. 1 involves putting the arm through an opening at the side of the vest 5 to form the arm support of the sling as it that works like a tunnel which the arm resting through it. The second option is using it with a block 8 of foam that is illustrated in FIGS. 2-6. This keeps the arm in abduction. In a third option is adding another block 10 of foam shown in FIG. 7 to support the arm in more abduction (somewhere between 60 to 90 of abduction).

[0029] The sling 10 also includes fastening means, such as hook and loop fasteners 11 in both the front and back of the vest at the upper portions near the shoulder seams to allow ice packs can be attached to those loops for cold compress.
