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.
Claims21
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.
