摘要： An occupant protection system for protecting a vehicle occupant sitting in a seat includes a seatbelt that includes a lap belt for arresting the pelvis of the occupant, and an airbag that is stored in the lap belt. The airbag as deployed includes a main inflatable portion for protecting an upper body of the occupant, and a head protecting portion that is located in a vicinity of an upper end of the main inflatable portion for protecting a head of the occupant. The head protecting portion includes a front inflatable portion for covering a front side of the head, and a pair of side inflatable portions that extend rearward from left and right ends of the front inflatable portion for covering sides of the head. Each of the side inflatable portions is configured to be deployed in such a manner that a space is formed between itself and the head.

摘要： An airbag device includes: an airbag having an exhaust hole capable of discharging a part of the inflation gas introduced therein upon opening; and an opening/closing control device capable of controlling opening/closing of the exhaust hole. The airbag has: a flexible bag main body; a discharge part having the exhaust hole; and a coupling member. Peripheral edges of a pair of peripheral wall constituting parts are joined to form the bag main body and the discharge part. Discharge part forming portions, which constitute the discharge part, partially protrude in the peripheral wall constituting parts, respectively. An opening, which constitutes the exhaust hole, is formed in a region, which is closer to a tip end-side of the discharge part than seal parts crimped to each other when the discharge part is pulled into the bag main body.

摘要： An airbag apparatus includes two airbags. The airbags are respectively accommodated in side accommodation portions in a seat back. The airbags include two side inflation portions and two front inflation portions. Each airbag further includes a tether. Each airbag includes a non-inflation portion. Each tether includes a pass-through section at which the tether is passed through the non-inflation portion. A portion of each tether between the pass-through section and a distal end is arranged along a rear surface of the front inflation portion. A portion of each tether between the pass-through section and a basal end is arranged along an inner surface of the side inflation portion. The basal end of each tether is configured to be fixed to a rear end of the side inflation portion or the seat back. The distal end of each tether is fixed to a front end of the front inflation portion.

摘要： An airbag apparatus is configured to be used for a vehicle seat including an accommodation portion. The airbag apparatus includes an airbag. The airbag is configured such that a portion of the airbag ejected from the accommodation portion to the position beside the headrest is deployed and inflated in a position rearward of the seat back, and is inflated and deployed away from the accommodation portion in the width direction in a position rearward of the headrest, and that another portion of the airbag ejected from the accommodation portion to the position beside the headrest is deployed and inflated in a position forward of the seat back, and is deployed and inflated in a position forward of a head of an occupant seated in the vehicle seat and away from the accommodation portion in the width direction, so as to wrap around the head.

摘要： An airbag includes, in a rear portion thereof, a passenger protection region for protecting a passenger. The passenger protection region includes a front-collision arresting plane, an oblique-collision arresting plane that is disposed on a left side and/or right side of the front-collision arresting plane, and an arresting recess that is disposed between the front-collision arresting plane and the oblique-collision arresting plane. Further, the airbag internally includes a tether that joints a front end portion of the airbag and the bottom of the arresting recess, and an auxiliary tether that joints the front end portion of the airbag and a side edge region of the front-collision arresting plane apart from the arresting recess. The tether and the auxiliary tether are designed to be deployed generally symmetrically with respect to a line that runs in a front and rear direction through a mounting center of the airbag to a case of the airbag.

摘要： A variable vent mechanism has an air bag having a vent hole, a flap attached to the air bag at a first fix portion and covering the vent hole, a strap extending from a connection end of the flap, fixed to an attachment portion at a second fix portion, and fixing the flap in a closed position where the vent hole is closed, and a device which brings the strap into a free state. A relationship L3/L4 between a maximum length L3 between the first fix portion and the connection end in a first direction connecting the first and second fix portions, and a maximum length L4 of the first fix portion in a second direction orthogonal to the first direction satisfies 0.5≤L3/L4≤3.0. A length of the flap in the second direction is shorter on the connection end side than on the first fix portion side.

摘要： A front passenger seat airbag includes an attachment portion provided on a front end side when inflation has been completed, an occupant protection portion provided on a rear end side to protect the occupant when inflation has been completed, and a cavity portion formed at an intermediate portion between the attachment portion and the occupant protection portion in a manner of penetrating the front passenger seat airbag substantially along a left-right direction. A left edge side and/or a right edge side of the occupant protection portion when inflation has been completed is formed with a protruding region protruding rearward and outward with respect to a central region. At least one of upper and lower edges of an occupant side panel is coupled to an end of the peripheral wall panel. An outer peripheral panel portion of the panel portion is a concave portion in a flatly deployed state.

摘要： An occupant protection system for protecting a vehicle occupant sitting in a seat includes a seatbelt that includes a lap belt for arresting the pelvis of the occupant, and an airbag disposed in the lap belt. The airbag is coupled to the lap belt in such a manner as to be movable relative to the lap belt in a left and right direction, and includes a main inflatable portion that is deployable in front of upper body of the occupant, and a positioning inflatable portion that protrudes from a lower end region of the main inflatable portion. The positioning inflatable portion includes a contact surface that contacts and is supported by an environmental member which is disposed in a circumference of the lap belt at airbag deployment, whereby helps align a center in the left and right direction of the main inflatable portion generally with that of the upper body.

摘要： A seat cushion airbag apparatus is applied to a vehicle seat in which a seat cushion includes a cushion part and a support portion. An airbag, including an inflatable portion, is disposed between the support portion and the cushion part. The inflatable portion includes: a rear inflatable portion that inflates on a lower side of buttocks of an occupant; a front inflatable portion that inflates on a lower side of a femur of the occupant; and a connection portion that connects the rear inflatable portion and the front inflatable portion. A tilting plate is disposed between the support portion and the cushion part and is supported to be tiltable in an upper-lower direction by a shaft provided rearward of the front inflatable portion, the tilting plate including a flat pressure receiving portion that receives pressure of inflation gas from a lower side through at least the front inflatable portion.

摘要： An airbag is configured using a rear surface side when inflation is completed as an occupant protection section. The occupant protection section includes a frontal collision restriction surface, oblique collision restriction surfaces formed both on the left and right sides of the frontal collision restriction surface, and restriction recessed portions installed between the frontal collision restriction surface and each of the oblique collision restriction surfaces. The airbag installs a recessed portion tether that links a tip end side of a recess of each of the restriction recessed portions and a front end side of the airbag to each other to the inside thereof, and when inflation is completed, at the time of substantially dividing the region into two in the left-right direction around the vicinity of the attachment center to the storage part, a remote side region on a side away from a driver seat and a driver seat side region on the driver seat side are provided. The capacity of the remote side region is set to be smaller than that of the driver seat side region.
