Then, the bags are finally folded by being roll-folded from the leading ends toward the base end parts thereof.

Abstract: An airbag device is provided in which the airbag device is made by folding an airbag having a left airbag section and a right airbag section with a new folding method. An airbag includes a left airbag section and a right airbag section that are inflated on the left and right, respectively, in front of a passenger, and a base chamber that communicates base ends of the airbag sections with each other. When the airbag is folded, first, the left airbag section and the right airbag section are primarily folded so as to have a reduced vertical width, thereby forming primary folded bodies that are elongated in forward and rearward directions. Then, the primary folded bodies are folded so as to have a reduced longitudinal width, thereby forming a secondary folded body. Thereafter, the base chamber is flattened and the secondary bodies are placed on the base chamber.

Abstract: An airbag is provided in which connecting belts extending from opposed surfaces of a left airbag section and a right airbag section can be connected easily to each other and which can be manufactured easily. In one form, the airbag is composed of four panels; an inside panel, a right outside panel, a left outside panel and a proximal panel. Connecting belts are connected to the inside panel. The respective connecting belts are each formed with an insertion portion by folding a cloth fabric having a pair of end sides at about a midsection thereof. Rod-shaped jigs are inserted into the respective insertion portions. In a state in which the connecting belts are overlapped, the jibs are fixed in parallel at a predetermined distance, and width control tethers are pulled in the directions away from each other. Accordingly, a tensile force is applied to the respective connecting belts, and hence a tensed flatly extended state is achieved.

The airbag includes a left half airbag with a vent hole to be inflated at a front left of a vehicle occupant, and a right half airbag with a vent hole to be inflated at a front right of the vehicle occupant. The distal ends of the left half airbag and the right half airbag are spaced part from each other to form an empty space therebetween facing the vehicle occupant when the airbag is inflated.

Abstract: An airbag for protecting an occupant of a vehicle includes a left outer panel for forming an outer surface of a left half airbag and a right outer panel for forming an outer surface of a right half airbag. The airbag also includes an inner panel for forming inner surfaces of the left and right half airbags, and a base-end panel for forming a base-end chamber for the left and right half airbags. The airbag is configures so that the left and right half airbags are inflated with gas passing through the base-end chamber.

Abstract: An airbag includes a bag portion to be inflated at a location close to an occupant and a pressure sensor mounted on an inner surface of the bag portion. A harness is connected to the pressure sensor to extend along the inner surface of the bag portion. An airbag device includes the airbag and a gas generator for inflating the airbag. Accordingly, high-speed air flow from the gas generator does not affect the pressure sensor, and it is possible to detect the pressure precisely.

The airbag further includes a constraining device for constraining lateral widths of the left half airbag and the right half airbag when the airbag is deployed.

Abstract: An airbag device has an airbag and an inflator for inflating the airbag. The inflator disposed at a base side of the airbag ejects gas to inflate the airbag such that a distal end of the airbag moves away from the base side of the airbag. The airbag includes a left half airbag to be inflated at a front left side of a vehicle occupant and a right half airbag to be inflated at the front right side of the occupant. Distal ends of the left and right half airbags are separated by a space facing the occupant when the airbag is inflated.

The left and right half airbags have primary folded portions having vertically elongated folded states and secondary folded portions having vertically folded states to form a finally folded state.

Abstract: Rotation of an input shaft is directly transmitted to a front carrier of a planetary gear mechanism, and rotation, which is speed-changed and reversed by a toroidal-type continuously variable speed change unit, is transmitted to a first sun gear. When a Low clutch is applied, rotation of an output carrier of a simple planetary gear unit is transitted to a counter gear mechanism via a common carrier, and then output at an output shaft. When a High clutch H is applied, rotation of a second sun gear is transmitted to the output shaft. Thus, the pinion shaft is shortened and the service life span of a supporting bearing is increased as compared with a planetary gear mechanism that has a three-step pinion.

The airbag includes a left airbag section, a right airbag section, and a belt strap disposed in one of the left and right airbag sections located closer to a vehicle body side for connecting a portion of the airbag section on the vehicle body side and an opposite portion. A height H1 in a vertical cross section from a lowest level to a joint portion between the belt strap and the portion is within a range from 0.4 H to 0.8 H, wherein H represents an entire height. A height H2 from the joint portion between the belt strap and the opposite portion is within a range from 0.3H to 0.6H, and is smaller than H1.

Abstract: An endless transmission belt is provided with a link plate, and a pair of joint pins that are retained by the link plate. Through the rolling of mutually contacting faces of the joint pins, link plates are mutually and rotatably connected into an endless chain. One joint pin of the pair is a pin with a large sectional area that transmits driving force from a pulley and the link plate, whereas the other joint pin of the pair is a pin with a small sectional area that transmits the driving force from the driving pin to the link plate. In order to reduce the concentration of stress on the side retaining the pin with a small sectional area, a peripheral width of the link plate on that side is made wider than the peripheral width on the side retaining the pin with a large sectional area.
