Abstract
A life preserver has one or more torso portions 3, 4 extending over the front of a wearer's torso in use: a neck portion extending behind the wearer's neck in use; a first inflatable bladder 80 configured to provide buoyancy primarily to the one or more torso portions when inflated; and a second inflatable bladder 60 configured to provide buoyancy to the neck portion when inflated; and inflation means 112-118 for controlling inflation of the first bladder and the second bladder such that the second bladder begins inflation after the first bladder.
Claims14
A life preserver comprising:
- one or more torso portions configured to extend over a front of a wearer's torso in use;
- a neck portion configured to extend behind the wearer's neck in use;
- a first inflatable volume configured to provide buoyancy primarily to the one or more torso portions when inflated;
- a second inflatable volume configured to provide buoyancy to the neck portion when inflated;
- and
- an inflation system configured to control inflation of the first inflatable volume and the second inflatable volume such that the second inflatable volume begins inflation after the first inflatable volume.
A method of operating a life preserver having one or more torso portions configured to extend over a front of a wearer's torso in use, a neck portion configured to extend behind the wearer's neck in use, a first inflatable volume configured to provide buoyancy primarily to the one or more torso portions when inflated, and a second inflatable volume configured to provide buoyancy to the neck portion when inflated, the method including controlling inflation of the first inflatable volume and the second inflatable volume such that the second inflatable volume begins inflation after the first inflatable volume.
A method of operating a life preserver having one or more torso portions configured to extend over a front of a wearer's torso in use and a neck portion configured to extend behind the wearer's neck in use, the method including inflating a first inflatable volume to provide buoyancy primarily to the one or more torso portions to rotate a wearer from a face-down position to a face-up position on water, and subsequently inflating a second inflatable volume configured to provide buoyancy to the neck portion to increase the distance of the wearer's mouth from the water surface and/or to vary a face plane angle of the wearer.
