Abstract

The present disclosure seeks to reduce the effects of rotational and linear acceleration experienced by the body of a user in response to an impact force. Modular disengaging systems of the present disclosure are generally suitable for coupling to protective equipment to provide a disengaging motion between various layers such that the effects of the impact force to the body of the user are reduced. Generally described, the modular disengaging systems of the present disclosure include layers configured to facilitate relative lateral motion therebetween upon an impact force.

First claim

The invention claimed is:

1. A modular disengaging system for interfacing with the body of a user, comprising:
a first layer couplable to a body-facing surface of a protective equipment, the first layer having a first surface opposite a second surface;
a second layer positioned adjacent to the second surface of the first layer;
a third layer having a first surface positioned adjacent to the second layer, the third layer having a second surface opposite the first surface of the third layer; and
a fourth layer comprising a plurality of fourth layer portions, each fourth layer portion having a first surface positioned adjacent and coupled to the second surface of the third layer, each of the fourth layer portions having a second surface opposite the first surface of the fourth layer portion, the second surface of the fourth layer portion being configured to contact the body of the user, wherein the plurality of fourth layer portions are spaced apart by spaces along the second surface of the third layer, wherein the spaces are defined by a gap extending from the second surface of the third layer to the second surface of the fourth layer;
wherein edges of the first layer are coupled to edges of the third layer, forming an enveloped sealed space enclosing the second layer between the first layer and the third layer;
wherein the second layer is configured to facilitate relative lateral motion between the first layer and the third layer upon an impact force acting on the modular disengaging system to reduce rotational acceleration and linear acceleration of the body of the user.

2. The modular disengaging system of claim 1 , wherein the first layer comprises an anchoring layer configured to removably couple the modular disengaging system to the body-facing surface of the protective equipment.

3. The modular disengaging system of claim 2 , wherein the anchoring layer comprises a material selected from the group consisting of hook and loop closures, adhesive, stiches, glue, a button system, a clip system, a peel-and-stick material, and combinations thereof.

4. The modular disengaging system of claim 1 , wherein the modular disengaging system is configured to conform to the body-facing surface of the protective equipment.

5. The modular disengaging system of claim 1 , wherein the modular disengaging system is configured to be couplable to a fitting system of the protective equipment.

6. The modular disengaging system of claim 1 , wherein the modular disengaging system is configured to be couplable to a rib member of the protective equipment.

7. The modular disengaging system of claim 1 , wherein the first layer is configured to be directly coupled to the body-facing surface of the protective equipment.

8. The modular disengaging system of claim 1 , wherein the first layer and the third layer are coupled at a perimeter of the modular disengaging system.

9. The modular disengaging system of claim 1 , wherein the first layer and the third layer are coupled using a coupling selected from the group consisting of a heat seal, a radio frequency seal, a sonic frequency seal, an ultrasonic frequency seal, hook and loop closures, an adhesive, stitches, a button system, a clipping system, a peel-and-stick material, and combinations thereof.

10. The modular disengaging system of claim 1 , further comprising a plurality of intermediary layers disposed between the first layer and the third layer, each of the plurality of intermediary layers having a disengaging layer therebetween, wherein the disengaging layer is configured to facilitate lateral relative motion between the intermediary layers, and wherein the plurality of intermediary layers is configured to facilitate lateral relative motion between the first and third layer upon an impact force acting on the modular disengaging system.

11. The modular disengaging system of claim 1 , wherein the second layer comprises a lubricant.

12. The modular disengaging system of claim 11 , wherein the lubricant is selected from the group consisting of a liquid, a solid, and a gas.

13. The modular disengaging system of claim 1 , wherein the second layer comprises a plurality of filaments bridging the first layer and the third layer.

14. The modular disengaging system of claim 1 , wherein the plurality of fourth layer portions is coupled to the third layer using a coupling selected from the group consisting of a heat seal, a radio frequency seal, a sonic frequency seal, an ultrasonic frequency seal, hook and loop closures, an adhesive, stitches, a button system, a clipping system, a peel-and-stick material, and combinations thereof.

15. The modular disengaging system of claim 1 , wherein the plurality of fourth layer portions is coupled to the third layer at a perimeter of the third layer.

16. The modular disengaging system of claim 1 , wherein the plurality of fourth layer portions is coupled directly to the surface of the third layer.

17. The modular disengaging system of claim 1 , wherein the plurality of fourth layer portions has an area smaller than an area of the surface of the third layer.

18. A kit, comprising:
a plurality of the modular disengaging systems of claim 1 , wherein each of the plurality of modular disengaging systems is configured to be couplable to a body-facing surface of a protective equipment.

19. The kit of claim 18 , wherein each of the plurality of modular disengaging systems is configured to be couplable to a different portion of the body-facing surface of the protective equipment.

20. The modular disengaging system of claim 1 , wherein an edge surrounding an entire perimeter of the third layer is coupled to the second surface of the first layer to form the enveloped sealed space enclosing the second layer between the first layer and the third layer.

21. A modular disengaging system for interfacing with the body of a user, comprising:
a first layer couplable to a body-facing surface of a protective equipment;
a second layer positioned adjacent to the first layer;
a third layer positioned adjacent to the second layer; and
a fourth layer comprising a plurality of fourth layer portions positioned adjacent and coupled to a surface of the third layer, each of the fourth layer portions being configured to contact the body of the user, wherein the plurality of fourth layer portions are spaced apart along the surface of the third layer;
wherein the first layer is coupled to the third layer to form an enveloped space enclosing at least a portion of the second layer between the first layer and the third layer;
