- Claim: 1. A site-selectable, helmet-installable, non-springy load-cushioning pad deployable as one of a collection of plural, spaced pads inside the shell of a helmet comprising compressible, non-springy, viscoelastic, urethane foam componentry with a structure possessing a load-response behavior which (a) resists sudden-movement rapid compression, yet (b) is less resistive to slow-movement compression, wherein said urethane foam componentry compression characteristics are degraded when exposed to water-based moisture, and completely covering said componentry, an encapsulating elastomeric film formed of material which functions simultaneously, over the entire outside surface of said componentry, to block all outside water-based moisture from reaching said componentry, while at the same time offering over the entire outside surface bidirectional gas permeability of all non-water-based gases to preserve non-springiness of the pad as a whole.
- Claim: 2. The pad of claim 1 , wherein said foam componentry is acceleration-rate (strain-rate) sensitive.
- Claim: 3. The pad of claim 1 , wherein said foam componentry exhibits a slow-return, slow push-back-force characteristic.
- Claim: 4. The pad of claim 1 , where said foam componentry is layered, and includes at least two operatively adjacent layers.
- Claim: 5. The pad of claim 2 , wherein said foam componentry is layered, and includes at least two operatively adjacent layers.
- Claim: 6. The pad of claims 4 , wherein said at least two layers differ from one another in load-response, energy-absorption characteristics.
- Claim: 7. The pad of claim 5 , wherein said at least two layers differ from one another in load-response, energy-absorption characteristics.
- Claim: 8. The pad of claim 4 , wherein said at least two layers differ in hardness.
- Claim: 9. The pad of claim 5 , wherein said at least two layers differ in hardness.
- Claim: 10. The pad of claim 6 , wherein, when the pad is installed appropriately in a helmet, the layer possessing the lower load-response, energy-absorption characteristic is disposed intermediate (a) the other layer, and (b) the space in the helmet provided for receiving a wearer's head.
- Claim: 11. The pad of claim 7 , wherein, when the pad is installed appropriately in a helmet, the layer possessing the lower load-response, energy-absorption characteristic is disposed intermediate (a) the other layer, and (b) the space in the helmet provided for receiving a wearer's head.
- Claim: 12. The pad of claim 8 , wherein, when the pad is installed appropriately in a helmet, the layer possessing the lesser hardness is disposed intermediate (a) the other layer, and (b) the space in the helmet provided for receiving a wearer's head.
- Claim: 13. The pad of claim 9 , wherein, when the pad is installed appropriately in a helmet, the layer possessing the lesser hardness is disposed intermediate (a) the other layer, and (b) the space in the helmet provided for receiving a wearer's head.
- Claim: 14. The pad of claim 6 , wherein, with the pad disposed in operative condition in a helmet, said foam componentry has a helmet-facing side, and an opposite, wearer's-head-facing side, the layer in this componentry which possesses the lower load-responsive, energy-absorption characteristic is disposed toward said wearer's-head-facing side relative to the other layer, and which further comprises a moisture-wicking material disposed intermediate said layer with the lower load-responsive, energy-absorption characteristic and the space in the helmet provided to receiving a wearer's head.
- Claim: 15. The pad of claim 7 , wherein, with the pad disposed in operative condition in a helmet, said foam componentry has a helmet-facing side, and an opposite, wearer's-head-facing side, the layer in this componentry which possesses the lower load-responsive, energy-absorption characteristic is disposed toward said wearer's-head-facing side relative to the other layer, and which further comprises a moisture-wicking material disposed intermediate said layer with the lower load-responsive, energy-absorption characteristic and the space in the helmet provided to receiving a wearer's head.
- Claim: 16. The pad of claim 8 , wherein, with the pad disposed in operative condition in a helmet, said foam componentry has a helmet-facing side, and an opposite wearer's-head-facing side, the layer in this componentry which possesses the lesser hardness is disposed toward said wearer's-head-facing side relative to the other layer, and which further comprises a moisture-wicking material disposed intermediate said layer with the lesser hardness and the space in the helmet provided for receiving a wearer's head.
- Claim: 17. The pad of claim 9 , wherein, with the pad disposed in operative condition in a helmet, said foam componentry has a helmet-facing side, and an opposite wearer's-head-facing side, the layer in this componentry which possesses the lesser hardness is disposed toward said wearer's-head-facing side relative to the other layer, and which further comprises a moisture-wicking fabric material disposed intermediate said layer with the lesser hardness and the space in the helmet provided for receiving a wearer's head.
