Abstract: An air belt device includes a first cover member and a second cover member connect to each other defining an interior surface having an interior cavity. An inflatable member is at least partially disposed within the interior cavity defined by the first cover member in a non-inflated state. The inflatable member is folded inward so a peripheral sewn portion is placed in a center portion of the first cover member.

Abstract: An inflatable member is restricted to expand outwardly in the vehicle width direction and allowed to expand upwardly to a position facing a side of an occupant's head when a lateral collision occurs. A belt guide mounted on the shoulder portion of a seat back guides a restraint webbing, including an inflatable member that is provided for supporting the head of a vehicle occupant when inflated, and allows a guide hole to be vertically enlarged by being projected upwardly in the vehicle vertical direction when the inflatable member is inflated. The inflatable member is thereby expanded so as to form a vertically extended shape regulated by the guide hole and disposed to an upward position facing the side of the occupant's head when a lateral collision occurs.

Abstract: A seat belt apparatus including a seat belt through anchor including a hanging shaft that a seat belt withdrawn from a retractor is hung on. The seat belt anchor also includes an anchor base that supports both ends of the hanging shaft. The anchor base includes a shaft non-rotatably supported by the anchor base at both ends and a tube body rotatably attached outside the shaft. The seat belt through anchor additionally includes a stopping mechanism for preventing rotation of the hanging shaft when a pressing force of a predetermined magnitude or more is applied to the tube body from the seat belt.

Abstract: An airbelt apparatus including a belt guide that is capable of moving so that an expansion portion of the airbelt may expand upward alongside an occupant's head. The belt guide also limits an expanding shape of the expansion portion.

Abstract: An air belt apparatus for use in a vehicle is provided to improve the comfort of the webbing during normal operation by thinning the webbing that passes through a shoulder anchor, while extending a developing length of an expanding portion upward when the expanding portion is expanded. The air belt apparatus includes webbing corresponding to the chest of an occupant, an expanding portion provided in the webbing, and folded back so as to be developed up to a position corresponding to a head of the occupant at a time of expansion, and an extending portion covering the expanding portion and extended upward from an upper end of the expanding portion, and further includes an elastic cover being expandable along the expansion of the expanding portion, and a non-extendable sheet member that enables the extending portion to pass through the shoulder anchor by reinforcing the extending portion of the elastic cover.

Abstract: The disclosed passenger constraining apparatus includes an inflated inflatable portion which may be placed at a high position around a lateral side of a passenger's head without using a high-capacity inflator. The passenger constraining device may include a passenger constraining belt comprising an inflatable portion configured such that at least a portion of the inflatable portion is arranged near the lateral side of the head of the passenger and a push-up device for pushing up the inflatable portion.

Abstract: An air belt apparatus is provided wherein a gas-supplying source for operating a chest portion expansion portion and a pretensioner are mounted in limited space in a motor vehicle seat by commoditizing the gas supplying source. An air belt apparatus for use in a motor vehicle includes chest-restraint webbing having a chest expanding portion corresponding to a chest portion of an occupant at expansion, lumbar-restraint webbing being pulled out from a retractor, and corresponding to a lumbar portion of the occupant, and a gas-supplying source. Since the gas-supplying source that supplies gas to the chest expanding portion and the pretensioner are unified and commoditized, the gas supplying source can be mounted using only a limited amount of mounting space in a motor vehicle seat.

Abstract: The disclosed passenger constraining apparatus includes an inflated inflatable portion which may be placed at a high position around a lateral side of a passenger's head without using a high-capacity inflator. The passenger constraining device may include a passenger constraining belt comprising an inflatable portion configured such that at least a portion of the inflatable portion is arranged near the lateral side of the head of the passenger and a push-up device for pushing up the inflatable portion.

Abstract: Inflation is sped up of the head-side portion of an occupant restraint belt that passes by the head of an occupant and routed across the front of the occupant, and which is inflatable from the head-side portion disposed on the side of the occupant's head across the front portion disposed at the front of the occupant. A shoulder belt section of an occupant restraint belt has a head-side portion located on the side of the head of an occupant; and a front portion located across the front of the occupant. The shoulder belt section has a structure in which, upon inflation, the head-side portion becomes thicker than the front portion, and the front portion becomes substantially even in thickness in the longitudinal direction.

Abstract: An occupant restraint belt is routed above the upper surface of the shoulder of an occupant to the front of the occupant. The part of the occupant restraint belt from above the upper surface of the occupant's shoulder to the front of the occupant is inflatable, and can be brought into contact with the upper surface of the occupant's shoulder without an excess increase in the volume of the inflatable portion. A shoulder belt section of the occupant restraint belt has an over-the-shoulder portion located above the upper surface of the shoulder of an occupant; and a front portion located across the front of the occupant. The shoulder belt section has a structure in which the part from the front portion to the over-the-shoulder portion inflates into a shape curved along the upper surface of the occupant's shoulder.

Abstract: An inflator assembly that has a shorter entire length and can be manufactured easily. The inflator assembly includes a pipe, a piston holder, first and second pipe holding plates, a bracket, and an inflator casing. The pipe is inserted through a pipe through hole in the base of the piston holder, through pipe through holes in the pipe holding plates, and through a spacer ring. The base of the piston holder, the spacer ring, and the pipe holding plates are clamped together between first and second flanges of the pipe. The inflator casing is fitted around the outer periphery of a rear end portions of the pipe and has an inward flange that is clamped and fixed between the first and second flanges of the pipe. Second and third flanges are formed by deforming portions of the pipe to have a larger diameter.

Abstract: A tongue of an inflatable belt device which allows a lap belt anchor to be easily assembled to a tongue body is provided. A tongue plate is provided on its one surface with hook-like projections for coupling a lap belt anchor to the tongue plate, and stoppers for preventing the lap belt anchor engaged with the projections from coming off the projections. Each stopper is supported by a plate spring. As receiving holes are engaged with the projections, the stoppers come in contact with the front end face of the lap belt anchor.

Abstract: A latching apparatus for an inflatable belt device which achieves reduction in the gas leakage without losing the smoothness of insertion of a tongue into a buckle, or which achieves reduction in the manufacturing cost and the weight of the latching apparatus. A tongue and a buckle of a latching apparatus for an inflatable belt device have pipes (a tongue pipe, a buckle pipe), through which gas for deploying an inflatable belt flows. The end of the buckle pipe is covered by a buckle cap which is broken when an inflator is actuated. The buckle cap is biased upwardly by a spring fitted around the buckle pipe. A space between the pipes is eliminated by the buckle cap, thereby achieving the reduction in gas leakage. Therefore, the need for excess gas is eliminated, thereby enabling miniaturization of the inflator.
