Abstract
There are known proposals for protective garments comprising ballistic and stab resistant body armour and inflatable bags or bladders to give buoyancy. The improved garment of this invention has body armour and a gas inflatable bladder between the armour and the wearer's body so as to be shielded by the armour whilst being arranged not to harm the wearer when the bladder inflates. This is facilitated by regulating the inflation pressure and/or by providing expansion joints in the garment that allow the armour to move away from wearer's body to make room for the inflated bladder.
Claims14
A protective body garment comprising:
- (a) a vest having a body having arm holes, the vest having an internal surface and an external surface, the vest having a front that, when worn, is adjacent to a wearer's chest and stomach, sides that, when worn, are adjacent to the wearer's sides, a back that, when worn, is adjacent to the wearer's back, and a pair of shoulders that, when worn, are above the wearer's shoulders;
- (b) penetration resistant armour located under the external surface of the vest;
- (c) an inflatable flotation bladder in the form of a bag between the inner surface of the vest and the penetration resistant armour, the bag extending from the front of the vest at one side of the vest, over one of the pair of vest shoulders, across the vest back, then back over the other one of the pair of vest shoulders and down the front of the vest at the other side of the vest;
- (d) expansion joints in the form of folded strips of material located around the arm holes such that, when the bag is in an inflated condition, the strips are unfolded and pushed outwardly, to provide buoyancy to the wearer of the garment when immersed in water;
- and
- (e) a pressure-regulating device to limit the pressure of the gas in the bag when the bag is inflated to minimize harm to the wearer by pressure on the wearer's body.
