Air bag against side collision

Abstract: PROBLEM TO BE SOLVED: To desirably regulate the expnsion condition of an air bag, and surely expand the air bag, eliminating any interference. SOLUTION: Gas spouting direction is controlled by connecting a bag 7 to an inflator 5 through a gas introducing portion 14 for restricting gas diffusion, wherein the bag 7 is comprised of a main body 9, a lower expanding portion 13, and an upper expanding portion 11 provided with a vent hole 16, so that the upper and lower expanding portion 11 and 13 are folded to make bellows within the main body. On expanding the air bag 7 by spouting gas from the inflator 5, at first, the expansion of the bag 7 is stared from the portion facing to an abdomen 8 where is more resistant to impact force than a breast 10 in the condition capable of absorbing the impact force, so that the expanding condition of the bag 7 is desirably controlled, resulting in the improvement in restricting an occupant 6. Further, vehicle body structure is provided not to interfere with the air bag when the upper and lower expanding portions 11 and 13 are expanded by inflating there from inside, so that the air bag 7 will be surely expanded.

Heat-radiator for CPU of a computer

Abstract: A heat-radiator for CPU of a computer, mainly including an air exhaust box, a collection funnel means and a bellows connecting the air exhaust box with the collection funnel means. An air blower and a detector means are disposed in the air exhaust box and connected by a circuit interface board inserted in an interface socket of the computer. The collection funnel means includes a heat-radiating plate located on the CPU, whereby the heat generated by the CPU is conducted through the heat-radiating plate and radiated therefrom to the ambient air and the hot air in the collection funnel means is sucked by the air blower to flow through the bellows and the air exhaust box to be exhausted from the computer housing.

Flexible pipe component for internal combustion engines exhaust ducts

Abstract: A flexible pipe component for internal-combustion engine exhaust ducts of motor vehicles is specified, having a metal bellows and connecting pieces connected on both sides thereto, in a gas-proof manner, a loosely wound clamping hose, welded to the connecting pieces, being arranged inside the bellows but separated radially from it, and, in the annular space between the metal hose and the bellows, there being arranged an insulating layer of thermally insulating, noise-absorbent, corrosion and heat-resistant material, which compresses when it is crushed axially and thus, if necessary, is brought into contact with the profile formed by the bellows and the metal hose, in the radial direction.

Cable bushing for motor vehicles

Abstract: A cable bushing is proposed which creates a connecting channel between a motor vehicle pillar and the hinge-side front end of an adjacent motor vehicle door. The cable bushing consists of an end section which can be clipped into the pillar side and of a tubular section which is separate therefrom and is connected via a bellows. The tubular section passes through the door cavity and emerges through the wall on the inside of the door so that the cables which are passed through are laid in a simple manner outside the cavity and can subsequently be covered by a lining element.

Variable capacity wobble-plate type compressor

Abstract: In a wobble plate type compressor with a variable capacity mechanism, the displacement is changed by varying the angle of the wobble plate (15), in response to a change in the pressure difference between a crank chamber (32) and a suction chamber (52). The pressure in the crank chamber (32) is maintained uniform by a valve, such as a bellows (63) and a needle valve (631) which allows excess pressure in the crank chamber to escape to the suction chamber.
