In a method for producing a multilayered heat shield, which has a first metal layer and a second metal layer that has an insulating layer arranged between the metal layers, the metal layers are connected at the edge by a flanging. To produce the heat shield, the first metal layer, the insulating layer and the second metal layer are placed into a first pressing tool. This is effected in such a way that an edge portion of the first metal layer protrudes beyond an edge portion of the second metal layer. The insulating layer is set back from the edge portions of the first metal layer and of the second metal layer.

A thermal barrier material for use in shielding components of a vehicle from hot exhaust surfaces includes 35 to 53% of a plurality of clays by weight and a remainder including magnesium silicate, alumina trihydrate, alumino-borosilicate glass, rock wool, basalt fiber, acrylamide copolymer coagulant, acrylic latex, fatty alcohol alkoxylate, or anionic polyacrylamide. A sample of the thermal barrier material, when exposed to a temperature of 400° Celsius, produces smoke having a density less than 5 g/cm.sup.3 as measured according to the ISO 5659-2:2006(E) standard.

Disclosed is a non-flammable thermal insulating composite substrate for motor vehicles including: a textile component constituted by a layer of needle-sewn non-woven fabric composed of a percentage of pre-oxidized polyacrylonitrile fiber included between 40% and 70%, preferably 58% and of the remaining percentage of polyethylene glycol-terephthalate fiber, the textile component having weight preferably 400 gr/m.sup.2; and a barrier fixed to the textile component using a spreading process, constituted by a thermoplastic resin based on low density polyethylene added with non-halogen flame retardants, the barrier having weight preferably 100 gr/m.sup.2. The composite substrate has the following features: a thickness included between 2 mm and 5 mm, preferably 3.8 mm; a weight included between 300 gr/m.sup.2 and 700 gr/m.sup.2, preferably 500 gr/m.sup.2; odorless; no emission of fumes; dimensionally stable, even at heatstroke, with a maximum variation of 1%; and non-flammability.

A heat shield sheet stacked at an upper surface of an upper plate of a vehicle includes a low emissivity coating layer having a white color, a base sheet on which the low emissivity coating layer is stacked, and a colored infrared transparent layer that is stacked on a solar radiation side of the low emissivity coating layer and transmits infrared rays. Since the low emissivity coating layer is a white color, the reflectance of sunlight is high. Therefore, the solar heat can be reflected efficiently by the low emissivity coating layer.

A heat shield system for shielding sensors from heat includes a sleeve portion made of heat-insulating material and has a hollow shape sized and shaped to be wrapped about a pipe of the exhaust treatment system. The sleeve has a longitudinal slit and an opening formed through the sleeve. The opening is configured to receive a sensor. The system includes a collar portion made of heat-insulating material and includes a base part configured to attach to the sleeve portion and a collar enclosure that extends radially from the base part. The collar enclosure defines an open chamber configured to surround the sensor and shield the sensor from heat while permitting access to the sensor. A closure is configured to retain the collar portion on the sleeve portion and hold the heat shield system in place.

A thermal insulation and fire protection felt product is provided. The felt product includes a first layer including a first plurality of nonwoven mechanically entangled oxidized polyacrylonitrile (PAN) precursor fibers bonded together by a first plurality of melted thermoplastic polyphenylene sulfide (PPS) fibers homogeneously mixed with the first plurality of mechanically entangled PAN precursor fibers. The first plurality of melted thermoplastic PPS fibers form a matrix of bond points between individual fibers of the first plurality of mechanically entangled PAN fibers. A second layer includes a second plurality of nonwoven mechanically entangled oxidized PAN precursor fibers bonded together by a second plurality of melted thermoplastic PPS fibers homogeneously mixed with the second plurality of mechanically entangled PAN precursor fibers. The second plurality of melted thermoplastic PPS fibers form a matrix of bond points between individual fibers of the second plurality of mechanically entangled PAN fibers.

An electrically driven vehicle includes a floor panel, a tunnel section, an electrical storage device, and an electric power line. The tunnel section is formed in a vehicle forward/rearward direction in a central portion of the floor panel in a vehicle width direction. The electrical storage device is disposed behind the tunnel section of the vehicle above the floor panel. The electric power line is disposed below the tunnel section and connected to the electrical storage device. The tunnel section has an opening portion formed in a rear end portion of the tunnel section located in front of the electrical storage device of the vehicle and through which the electric power line is inserted.

A motor vehicle comprises an impact protection device for a battery (1) mounted under the floor of the vehicle and separated from an exhaust muffler (2) by an intermediate heat shield (3), wherein, the device comprises a cushion (4) fastened opposite the battery (1) on the heat shield (3), the cushion (4) being able to deform when the muffler (2) moves forward contacting the battery (1) in order to absorb the kinetic energy resulting from an impact on the vehicle.
