Abstract
A self-righting underwater escape and surface survival suit includes an ascent hood and an inflatable bladder in fluid communication with the ascent hood. Breathable air from the vessel is used to inflate the inflatable bladder for ascent to and/or survival on the water surface. During ascent, breathable air is provided to the ascent hood from the inflated inflatable bladder. The inflated inflatable bladder is configured to provide self-righting of the wearer upon surfacing and to support the wearer on the water surface, even if the wearer is incapacitated or the ascent hood is opened.
Claims20
An escape and survival suit, comprising:
- an ascent hood configured to cover a head of a wearer of the escape and survival suit;
- and
- an inflatable bladder in fluid communication with the ascent hood, wherein with the inflatable bladder inflated with breathable air, the inflated inflatable bladder provides the breathable air to the ascent hood during ascent of the wearer a water surface, the inflated inflatable bladder being configured to support and self-right the wearer upon reaching the water surface.
An escape and survival suit, comprising:
- an ascent hood configured to cover a head of a wearer of the escape and survival suit;
- an inflatable bladder connectable to a breathable air supply on a vessel to inflate the inflatable bladder with breathable air for ascent of the wearer to a water surface;
- and
- at least one air valve connecting the inflatable bladder to the ascent hood, wherein the at least one air valve automatically opens in response to a pressure in the inflated inflatable bladder exceeding a first threshold pressure to provide breathable air to the ascent hood during ascent, the least one air valve automatically closing in response to the pressure dropping below a second threshold pressure to maintain inflation of the inflated inflatable bladder at the water surface to support and self-right the wearer at the water surface.
An escape and survival suit, comprising:
- an ascent hood configured to cover a head of a wearer of the escape and survival suit;
- and
- an inflatable bladder in fluid communication with the ascent hood and connectable to a breathable air supply on a vessel to inflate the inflatable bladder with breathable air, wherein the inflatable bladder includes a trapezoidal shape that overlies a chest of the wearer when inflated to automatically self-right the wearer from a face-down position to a face-up position on the water surface.
