FIELD OF DISCLOSUREThe field of this disclosure relates generally to a suspension system used to facilitate carrying a load and, more particularly, to an articulating load bearing suspension system for use with body armor.
BACKGROUNDBody armor is worn by individuals, such as military personnel, police, security guards, bodyguards or other individuals seeking bodily protection. One known type of body armor includes a carrying device (for example, a vest, a jacket) designed to carry one or more armor plates. The armor plates, which may be selectively removable from the carrying device, are specifically constructed to protect the wearer from being, for example, shot, stabbed or otherwise injured during an attack or other dangerous situation. As can be readily appreciated, some individuals including, but not limited to, combat soldiers and police officers in tactical units, often seek to maximize their bodily protection by wearing relatively robust body armor when knowingly entering potential hostile or other dangerous environments. Unfortunately, however, such robust body armor may be heavy, for example, weighing between twenty and forty pounds and cumbersome to move in. Moreover, the individuals wearing the body armor typically carry additional items (for example, weapons, ammunition, various tools) that are directly or indirectly attached to the body armor and, more specifically, to the carrying device. As a result, the individuals wearing the body armor may be carrying a load that approaches or even exceeds one hundred pounds.
With most known body armor, the majority of the weight of the armor plates and any additional items carried by the wearer rests on the user's shoulders, which stresses the wearer's spine. As can be readily appreciated, carrying the weight of the body armor and any load secured to the body armor can be quite wearing and may cause strain or even injury to the user's shoulders, back, spine, and/or other body parts.
Thus, there remains a need for an articulating load bearing suspension system for use with body armor that reduces the stress on the wearer while allowing for greater freedom of movement compared to known body armor.
SUMMARYIn one aspect, an articulating load-bearing belt for use with body armor generally comprises a first structural plate, and a second structural plate pivotally coupled to the first structural plate at a pivot point such that each of the first and the second structural plates are configured to independently pivot about the pivot point.
In another aspect, a load-bearing belt configured to transfer the weight of a load to a user's hips generally comprises a first structural plate including a first end portion positioned proximate the user's lower back, and a second structural plate including a second end portion positioned proximate the user's lower back. Each of the first and the second structural plates extend from the respective first or second end portion and is configured to be releasably secured about a corresponding hip of the user when worn. The first structural plate is pivotally coupled to the second structural plate at a pivot point such that each of the first and the second structural plates are configured to independently pivot about the pivot point.
In yet another aspect, a load-bearing suspension system generally comprises an article configured to house a load, a vertical stay coupled to the article and aligned with a user's spine, and a load-bearing belt pivotally coupled to the stay. The belt is configured to releasably secure the article around the user's hips such that, when secured, at least a portion of the load is supported by the user's hips. The load-bearing belt comprises a first structural plate and a second structural plate coupled to the first structural plate at a pivot point such that each of the first and the second structural plates are configured to independently pivot about the pivot point.
The belt 16 includes a padded sleeve 20 having a first side portion 22 (for example, a left side portion as viewed in the accompany figures) and a second side portion 24 (for example, a right side portion as viewed in the accompany figures) that each wrap at least partially around respective hips of the user and extend at least partially across the user's lower back when the ALBS system 10 is worn. In such a position, the belt 16 provides lumbar support for the user when the ALBS system 10 is worn. As seen in
Referring now to
Furthermore, the sleeve 20 is comprised of an elastomeric material that is configured to provide structural rigidity to the belt 16. More specifically, the elastomeric material of the sleeve 20 holds the structural plates 26, 28 in a neutral, generally horizontal position relative to the stay 18, such as the position of the first structural plate 26 in
The first structural plate 26 includes a front end 32 positioned proximate the user's hip and a back end 34 positioned proximate the user's spine. The first structural plate 26 also includes a curved top edge 36 that forms a hump proximate the user's back and slopes downward at the back end 34 such that the back end 34 is tapered to a rounded point 38 (shown in
The first and second structural plates 26, 28 are configured to be independently articulating such as by pivoting, rotating, or moving based on the movement of the user to maintain effective load distribution. More specifically, the first opening in the end 34 of the first structural plate 26 is concentric with the second opening defined in the end 42 of the second structural plate 28 such that the openings are configured to receive a common fastener 47 (for example, a pivot pin). In one embodiment, the fastener forms the single pivot point 48 about which each of the structural plates 26, 28 is configured to independently pivot relative to the pivot point 48.
The structural plates 26, 28 are pivotally coupled to the stay 18 to accommodate the user's hip angle. Additionally, the structural plates 26, 28 are configured to pivot about the pivot point 48 as the user moves to maintain an effective load distribution. More specifically, when the user walks, runs, kneels, bends, twists and/or climbs stairs, the user's hips articulate up and down on each side. If the belt 16 did not articulate correspondingly, and was formed without pivots, then when the user lifts their leg to step, their hip rises and pushes the load off center diagonally relative to the spine such that the load is not aligned with the user's spine, therefore disrupting the user's balance. However, the independently articulating structural plates 26, 28 in the belt 16 allow a greater freedom of movement while maintaining load stability. More specifically, when the user lifts their right leg to take a step (as shown on
Referring now to
In one embodiment, a second end 66 of the stay 18 is coupled to the first and second structural plates 26, 28 of the belt 16 at the pivot point 48. More specifically, the second end 66 includes an opening defined therein that is concentric with the openings defined in the first and second structural plates 26, 28 such that the fastener 47 is threaded through the three openings to enable the stay 18 to pivot about the pivot point 48 as depicted in
The common pivot point 48 allows for greater flexibility and mobility when the user orients their spine at an oblique angle with respect to the ground, such as to look around an object without moving their feet. During such a motion, the structural plate 26, 28 corresponding to the hip the user is leaning away from also pivots about the pivot point 48 to maintain load distribution. By relative pivoting of the stay 18 and the first and second structural plates 26, 28, the stay 18 remains aligned with the user's spine. In this manner, the belt 16 enables free movement of the user without inhibiting even load distribution. Alternatively, if the user only moves their back to lean such that their hips remain level, then the belt 16 may also remain level. The second end 66 of the stay 18 may be coupled to the belt 16 with a ball joint to allow the user to have several degrees of freedom to bend, twist, and rotate their upper body while maintaining stiffness in the vertical direction of the stay 18. Furthermore, the second end 66 of the stay 18 may include a coil spring (not shown) configured to allow some cushioning of shock directed in the vertical axis along the stay 18. In another embodiment, the second end 66 of the stay 18 may be coupled to the belt 16 at a location other than at the pivot point 48. Moreover, the stay 18 is comprised of a strong, flexible material, such as, but not limited to carbon fiber, that allows the user to repeatedly bend forward and backward and also to twist their upper body without restriction of the range of motion.
As illustrated in
Furthermore, the ALBS system 10 also includes an extension mechanism 74 that is coupled to at least one of the cover 58 of the vest 12, such as proximate the sleeve 62, and/or to the stay 18 itself. The extension mechanism 74 is configured to allow the stay 18 to extend and contract thereby allowing the user to bend forward and backward without changing the orientation of or otherwise moving the belt 16 relative to the user, as depicted by movement arrow 76. When the user bends forward, the curvature of the back causes the distance between the vest 12 and the belt 16 to increase. Similarly, the distance between the vest 12 and the belt 16 decreases when the user bends backward.
In one embodiment, the extension mechanism 74 allows the stay 18 to slide in the directions of arrows 76 within the sleeve 62 such that when the user bends forward or backward the stay 18 and the belt 16 actually remain in place while the vest 12 slides along the stay 18 which is slideably positioned within the sleeve 238 to correspond to the change in the user's orientation. In another embodiment, the stay 18 includes a telescoping section 77 such that the length of the stay 18 actually changes to correspond to the change in the length and curvature of the user's back. As such, bending forward does not cause the belt 16 to ride up from the user's hips to their waist and cause destabilization of the load. Similarly, bending backward does not cause the belt 16 to drive the load of the vest 12 onto the user's hips. The load remains stable and distributed between the user's hips and shoulders.
Those skilled in the art, given the benefit of this disclosure, will appreciate that the ALBS system is not confined to the specific application as described above (i.e., use with an armored vest). Rather, the ALBS system may be used with a wide variety of applications where it is desirable to transfer a load to a user's hips without departing from the scope of this disclosure. For example, according to some aspects, the ALBS system may be provided on a hiking backpack. In such embodiments, the weight of backpack may be beneficially transferred to the user's hip structure via the ALBS system in a similar manner as discussed. Similarly, in other embodiments, the ALBS system may be provided on a hydration pack (i.e., a bag configured to be worn on a user's back and store drinking water), or any other application where it is desirable to transfer a load from a user's shoulders, back, etc., to the user's hip structure. In each application, the location of the articulating structural plates of the ALBS system may provide similar benefits as described above.
The present disclosure describes supporting heavy upper body armor by transferring a portion of the load from the user's shoulder to the user's hips. The load transfer is accomplished in a manner such that the standard armor still fits the user in essentially the same manner, but allows for greater flexibility for torso and leg movement while providing upward support. The articulating load-bearing suspension system described herein includes a load-bearing belt having two independently articulating plates coupled together at a common pivot point. The independently articulating plates support the load from the body armor on the user's hips while still allowing the user to walk, run, kneel, climb stairs, twist, etc. without destabilizing the load.
