FIELDDescribed herein are various embodiments of unweighting systems for unweighting or offsetting an individual's load and methods of using such systems.
BACKGROUNDMethods of counteracting gravitational forces on the human body have been devised for therapeutic applications as well as physical training. Rehabilitation from orthopedic injuries or neurological conditions often benefits from precision unweighting (i.e. partial weight bearing) therapy.
Differential Air Pressure (DAP) systems have been developed to use air pressure in, for example, a sealed chamber to simulate a low gravity effect and support a patient at his center of gravity without the inconvenience of water-based therapies. DAP systems generally utilize a chamber for applying differential air pressure to a portion of a user's body. In order to use these systems, an air-tight seal must be established with the user's body. This seal typically requires that a close-fitting garment be worn. Wearing this close-fitting garment over other garments worn by the user, in addition to the necessary presence of the pressurized air chamber surrounding the user, however, can cause discomfort and/or restriction of the natural arm swing as the user moves. Moreover, in some instances, an individual may have limited or low degree of mobility, which may hinder his ability to access the chamber and/or garment.
An alternative to DAP systems are the less expensive traditional methods of counteracting the effects of gravity by suspending a person using a body harness to reduce ground impact forces. Suspension systems can be inexpensive in that these systems can be used with a user's existing home gym or exercise equipment. However, currently available harness systems are often uncomfortable and result in direct vertical lifting that can distribute weight unnaturally and uncomfortably on the user's body. Harness systems often employ the use of bungee or tensioning cords and cables that need to be hooked or unhooked to harnesses worn by the users. The harnesses themselves are generally uncomfortable as pressure points develop where the lifting force pulls on the user's body. In some cases, prolonged use with these harness suspension systems can result in injuries that range from mild skin abrasion or contusions to musculoskeletal injury.
As such, a need exists for a garment design that can be used with inexpensive unweighting system such as suspension systems and/or DAP systems that allow users to comfortably unload a portion of their weight. Additionally, a need exists for a garment design that can be used easily by users with mobility impairments.

The novel features of the invention are set forth with particularity in the claims that follow. A better understanding of the features and advantages of the present invention will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the invention are utilized, and the accompanying drawings of which:
Described herein are garments, such as shorts, configured to distribute a load during unweighting of a user. The garments can be configured to include a waist portion that sits proximate to a user's hips and leg portions configured to cover or surround a user's upper legs. The garment can include a pair of attachment mechanisms configured to attach to an unweighting device and one or more force distribution configured to distribute force to the user's thighs when a force is placed on the attachment mechanisms.
As described further below, the garments described herein (such as garment 700) can further include force distribution sections (not shown in
A similar garment 1100 is shown in
The force distribution sections can allow unweighting force (e.g. lifting force) and/or the unloaded weight of the user to be more evenly distributed.
Thus, referring to
As described in the embodiments above, the waist section 103 may also include one or more attachment elements 102a,b for attaching the garment to an unweighting system. The attachment elements 102a,b can include any mechanical means or mechanism for attaching or coupling the garment to an unweighting system, such as hooks, clips, loops, or Velcro. The attachment elements 102a,b may be attached to both the main body 101 and/or the force distribution section 108a,b. For example, in the case where a force distribution section 108a,b is placed onto of textiles or fabrics of the main body 101, the attachment element 102a,b may be fixed or secured to both fabrics.
The leg members 106a,b can extend from the waist section 103. In some embodiments, leg cuffs 107 can be placed at an end of the leg members 106a,b. In some embodiments, the leg members 106a,b have a length sufficient to cover and surround the user's thighs. In further embodiments, the leg members 106a,b may reach from the user's hips to partway down their thighs. In other embodiments, the leg members 106a,b may reach from above the user's waist and down to below the knees. In still other embodiments, the leg members may extend to the user's ankles or above the user's feet.
The force distribution sections 108a,b can extend from the attachment mechanisms 102a,b into the leg members 106a,b. The force distribution sections 108a,b can include straps made of webbing (e.g., of nylon or polyester), fabrics of different characteristics than the rest of the main body, and/or panels that are configured to cinch together.
In some embodiments, the force distribution sections 108a,b may redistribute or direct a lifting force applied to the user (i.e., through the attachment mechanisms 102a,b) into tensile force applied along predetermined lines, sectors or portions. In other embodiments, the force distribution sections 108a,b can be used in the garment 100 to convert a portion of a lifting force applied to the garment into a partial, complete or overlapping circumferential compression force. The tensile or compressive forces provided by the one or more force distribution sections 108a,b may assist in keeping the garment 100 in a desired position on the user's body, redistribute forces that would otherwise cause pain or unwanted rotation, and/or prevent the garment 100 from riding up the user's body during use. In some embodiments, a force distribution section 108a,b may include aspects that provide both tensile (lift) force distribution and compressive force distribution.
Suitable materials suited for use with the force distribution section 108a,b include, for example, natural fibers such as cotton or canvas and synthetic fibers such as nylon, neoprene, spandex, elastic fibers, elastomeric polymers (e.g. polyethylene), Lycra, or any blends of materials. In some embodiments, the fabrics used in a force distribution section 108a,b may have a weight of about 8 ounces/square yard, 12 ounces/square yard, or 10.9 ounces/square yard. The force distribution section may, additionally or alternatively, also include either a nonwoven or woven structure. In some embodiments, the force distribution sections 108a,b may include or be lined with a stretchable, breathable material.
In some cases, the force distribution sections 108a,b employ a woven structure with multi-directional weaving. For example, the woven structure may be a biaxial or triaxial braiding or weaving of the fabric fibers. In some embodiments, the force distribution section 1108a,b is made of a mesh or netted weave that is woven with large gaps or holes. In one aspect, the fabric is cut on a bias and incorporated into the garment so that the lifting force causes the fabric section to contract in a predetermined way (i.e., determined by the fabric cut, fiber orientation, weave, strand orientation and the like alone or in combination). In one example, the lifting force acts on the material of the force distribution section 108a,b that responds by tightening the grip of the garment on a portion of the user's body that is within the garment. In other embodiments, the force distribution sections 108a,b are made from a fabric 108a,b that has variable movement in different directions.
The main body 101 and the force distribution sections 108a,b can be attached together in any suitable manner. In some embodiments, the main body 101 and the force distribution sections 108a,b are integrated together, such as by being sewn together or seamlessly joined (or threaded) together, on a fiber level. In some embodiments, the force distribution section can be under or overlaid on the main body 101. For example, a woven or mesh fabric may be placed over the fabric of the main body. In other embodiments, the force distribution sections 108a,b are enclosed within another material that forms the garment 100. For example, shorts or pants suited for use as an unweighting garment may have an outer shell and an inner liner. For both ease of use, comfort and appearance, the force distribution section 108a,b may be disposed between the outer shell and inner liner and attached to one or both of the liner/shell.
Further, the main body 101 and the force distribution sections 108a,b may be made from the same or different materials. Further, in some embodiments, the structure and materials within either the main body 101 or the force distribution sections 108a,b may vary within the respective sections. For example, the weave of the force distribution sections 108a,b may be a biaxial weave in one section and a triaxial weave in another section. Similarly, the main body may 101 include a moisture wicking and friction reducing material at, for example, the crotch area, to keep the user comfortable during movement.

The attachment elements for the garments described herein can be any attachment element capable of releasably fixing the garment to an unweighting machine. For example, the attachment element can include a pulley or roller.
The unweighting garments described herein can advantageously be used to spread the unweighting force out across the user's body to avoid unwanted pressures and rotations. Exemplary garment embodiments similar to those described above are shown in
In some embodiments, the force distribution sections (such as the fiber weave) place a force on the thighs that changes the centers of force from the outside of the hips, where it applies a force pulling legs outwards, to be more in line with the hip joint, where the force will have a neutral effect on the legs. In some embodiments, the shorts move the center of force and distribute the force by use of a rigid member. In some embodiments, the user is unweighted from the sides (or laterally). Embodiments described herein are compatible with any type of suspension unweighting regardless of the angle or direction of the lifting force.
Aspects of the various embodiments described herein advantageously include one or more innovations that assist in overcoming the shortcomings of existing unweighting garments, mechanisms, or systems. Particular areas of improvement provided by the embodiments described herein include: (1) circumferential force conversion; (2) zoned differential compression; (3) hip joint neutrality; (4) quick attachment and detachment; and (5) and ease of access. Each of these general areas will now be described.
Circumferential force conversion: When vertical lifting force is applied to a garment of uniform material content, the garment tends to ride upwards on the user until the garment binds against the user's crotch area. Because users vary widely in size and proportions, shaping the garment has limited utility in this regard. Some of the embodiments described herein utilize materials cut and aligned on the bias in relationship to the vertical lifting force. When biased sections are pulled upwards by the lifting force, the cross-sectional areas contract, causing circumferential tension and a resulting radial compression proportional to the lifting force. Embodiments relating to aspects of this improvement include, for example, with the embodiments of
Zoned differential compression: With regards to the application of unweighting or lifting forces to the body via the suspension interface garment, different parts of the anatomy have different characteristics that make them more or less suited to the application of said forces. For example, the hips have high load tolerance and low taper. The thighs have moderate load tolerance (femoral artery) and moderate taper. The crotch or groin has no load capability and high taper. As such, different areas of the body need to be loaded differently to achieve a proper balance between maximum unloading and comfort. Embodiments relating to this improvement include, for example, the embodiments of
Hip joint neutrality: While DAP loads the user's lower body uniformly in terms of area with respect to air pressure and circumferentially with respect to garment tension, non-DAP systems that do not inhibit upper body motion tend to support the lower body garment at two discrete points, one at either side of the pelvis. Since the hip joints are inboard of where the unweighting loads are typically applied in these systems, an unnatural lateral torque pulls the legs out to the sides. At low loads and/or for short durations, this effect may not be noticeable. At higher loads or for longer duration usage, this becomes an issue. The embodiments described herein address this need in two ways. In one method, unweighting load attachment points are placed fore and aft, in line with the hip joint, to minimize the lateral moment. In another method, bands cross the pelvis from their attachment points, applying an inward force and counterbalancing moment on the opposite leg, resulting in a net zero moment. Embodiments relating to this improvement include, for example, the embodiments of
Quick sliding attachment/detachment: Current unweighting and safety systems provide fixed attachment points with respect to fore and aft movements of the hips. This constraint, while fine for gymnastic and strength movements, unnaturally inhibits hip rotation during running and walking. The current design allows for independent fore and aft motion. Embodiments relating to this improvement include, for example, the embodiments of
Ease of access: There is also a need to address the difficulty of accessing known harness systems when the user desires to remain in street clothes rather than athletic gear or wants to exercise in an unweighted environment while avoiding the process of removing and putting back on shoes. Each of the embodiments described herein may be sized in order to be worn over clothes.
