IMPACT RESISTANT MULTILAYER GLOVE Russian patent published in 2023 - IPC A41D19/00 A41D13/15 

FIELD: rubber goods.

SUBSTANCE: impact-resistant multilayer glove with automatic heating at low temperatures and restoration of shape after plastic deformation of an energy-absorbing element, including a layer with a wire in the form of a spiral winding made of an elastic-plastic material with a shape memory effect based on an equiatomic titanium-nickel alloy with electrical contacts at the ends, the wire along the entire length is included or integrated into the elastic plate element made of polyurethane and is equipped with an electrocontact heater connected to the electrical contacts of the spiral, the electrocontact heater is connected to a power source, and the spiral winding is fixed on a leather substrate that repeats the contours of the fingers of the glove, which is sewn to the base of the glove, the wire, the substrate and the base are covered with a latex coating, the elastic lamellar elements made of polyurethane are arranged in rows and are made of different sizes, proportional to the dimensions of the corresponding fingers of the glove in the form of alternating layers of latex and rubber granules, the power source is made on the basis of lithium batteries and is connected to the control unit, lithium batteries and the control unit is integrated into the elastic latex pockets of the cuff of the glove, the temperature gradient sensors are built into the control unit in the form of thermocouples, brought under the first, closest to the cuff, a number of elastic lamellar elements made of polyurethane, rubber granules are obtained from crushed products of secondary processing of rubber products of automobile tires.

EFFECT: enhancement of properties.
