Abstract: The towed vehicle connection determination system includes a towed vehicle presence determination unit that determines whether or not the towed vehicle is connected, based on at least two or more pieces of information among the weight estimation equipment, the peripheral condition detection equipment, and the vehicle rear monitoring equipment. Therefore, it is possible to improve the accuracy of determining whether or not the towed vehicle is connected as compared with the case of determining whether or not the towed vehicle is connected based on only one piece of information such as the weight estimation value and the captured image of the camera.

Abstract: A pouch-shaped air bag (12) is spread out in a circle. Then, the portion of the air bag (12) located outside the inflator (16) is folded into a wave-like pattern from four directions so that four side portions (61) are formed along the inflator (16). Next, each one of the four excess portions (62), which are continuously formed between each two adjacent side portions (61) and protrude outward, is placed along the outer face of each side portion (61). Thus, the air bag (12) can be easily folded compactly that can be smoothly unfolded.

Abstract: A comfortable water absorbent composite sheet which is a water absorbent sheet comprising a water absorbent layer, a water holding layer and a water impermeable layer successively arranged from the skin side, wherein the composite water absorbent sheet has a sufficient amount of water absorption with slight water-rewet to the skin by arranging a water-backflow preventing layer comprising a water impermeable sheet material having water penetrating holes between the water absorbent layer and the water holding layer and providing the total area ratio of the water penetrating holes accounting for 3% or above and below 40% of the whole area of the water-backflow preventing layer.
