A passenger protection device for a front passenger seat includes: an upper airbag that is installed in a front header of a vehicle, and is configured to inflate and deploy at a time of a frontal collision of the vehicle so as to be supported by a windshield from a front side of the vehicle; and a lower airbag that is provided separately from the upper airbag and installed at a front end of a vehicle cabin below the windshield in a vehicle height direction, the lower airbag being configured to inflate and deploy at the time of the frontal collision so as to be supported by a dashboard including an instrument panel from the front side of the vehicle.

An airbag includes a body, an insert opening and a flap member which covers the insert opening from inside of the airbag. A retainer is inside the airbag, and an inflator is inserted into a holding section of the retainer via the insert opening such that the root end protrudes from the insert opening. The flap member entirely covers the insert opening of the airbag body as unfolded and is joined to the airbag body, with a continuous seam, by the circumferential edge except the leading edge disposed towards the leading end of the inflator. The flap member thus covers the holding section. The retainer includes an open region which exposes an outer periphery of the inflator towards the flap member, and the leading edge of the flap member is positioned to be pressed against the outer periphery of the inflator via the open region at airbag deployment.

The invention describes an airbag (10) for a vehicle occupant restraint system, wherein the airbag (10) in the inflated state includes a front side (24) forming an occupant impact surface and an opposite rear side (22). The front side (24) and the rear side (22) are formed by shell portions (14, 16) of the airbag (10) being connected to each other at their outer edges (34, 36). The front side (24) is longer along a centerline (M) extending in the longitudinal direction of the airbag (10) than the rear side (22) so that, in the inflated state, the airbag (10) takes a curved shape. The front side (24) has at least one shaping line (42) extending substantially curved and transversely to the centerline (M) at which shaping line two shell portions (34, 36) are connected to each other. The respective outer edges (34, 36) of the front side (24) and the respective outer edges (34, 36) of the rear side (22) are of the same overall length.

An airbag includes an insert opening. An inflator is inserted into the airbag via the insert opening and set in a holding section of a retainer which is disposed inside the airbag. The retainer includes, at its end region disposed towards the insert opening of the airbag, two retaining pawls that are in engagement with a periphery of the insert opening. The insert opening is composed of a plurality of slits formed on a base material of the airbag such that one or more area among the slits serve as a bent sealing region that is bent inward and covers an outer periphery of the inflator. The slits include a pair of retaining slits that intersect each other. Each of the retaining pawls protrudes from a terminal of each of the retaining slits. A peripheral area of the retaining slits constitutes the bent sealing region.

An inflatable airbag assembly, such as a knee airbag assembly, including a support strap, wherein the support strap may be secured to an inflatable airbag cushion. The support strap may be configured to direct the deployment trajectory of the airbag cushion such that the airbag cushion is deployed rearwardly and upwardly within a vehicle. The inflatable airbag assembly may be configured to prevent injury to an occupant's hip, femur, knee, and/or lower leg.

A vehicle knee airbag device includes a protruding profile section configuring an instrument panel, a position of the protruding profile section being configured to be further toward a vehicle upper side than knees of a seated occupant; an upright wall section provided adjacent to a vehicle lower side of a lower wall of the protruding profile section; and a knee airbag module including a knee airbag. The knee airbag includes an occupant-side base cloth portion disposed on an occupant-facing side and a non-occupant-side base cloth portion disposed on a non-occupant-facing side of the knee airbag in an inflated and deployed state, the non-occupant-side base cloth portion being disposed adjacent to the upright wall section in the inflated and deployed state of the knee airbag.

A knee airbag apparatus for an autonomous vehicle, wherein a first cushion and a second cushion are deployed toward the knees of a passenger and a third cushion is deployed toward the feet and shins of the passenger according to a collision mode (head-on collision, offset collision or oblique collision) and a position (normal position or relaxation position) of a seat.

A curtain airbag apparatus (100) is provided with an inflator (106), and a cushion (102) stored, in an elongated storage form, on an inner side of a headliner above a front side window (110), and receives the gas to inflate. The cushion (102) in the storage form has a bent-over portion (142) which is formed by bending over a rear end (136) of the cushion (102) towards a center side thereof from a state in which the cushion (102) is rolled upwards. The state of the cushion (102) when the bending over is performed i.e. the rolled state of the cushion (102), is achieved by rolling the cushion (102) from a state in which a prescribed area at the rear end (136) of the cushion (102) in a deployed state is folded over towards the center side in the vehicle front-rear direction.

A knee airbag device includes: a knee airbag that is housed in a folded state at a lower end portion of an instrument panel, and that, due to gas being supplied thereto, is inflated and expanded along the instrument panel; an airbag case that houses the knee airbag; an airbag door portion that structures a lower surface of the airbag case, and that, due to a planned rupture portion rupturing due to inflation pressure of the knee airbag, is opened toward a vehicle front side; and a flap that is housed within the airbag case, one end portion of the flap being fixed to the airbag case, another end portion of the flap being a free end, and that, at a time of inflation and expansion of the knee airbag, unfolds, and covers the airbag door portion from a vehicle rear side.

An occupant protecting device for a vehicle has a knee airbag that is disposed at a seat front side of a vehicle seat, and that, at a time of a front collision of a vehicle, deploys, and restrains leg portions of a vehicle occupant seated in the vehicle seat. A foot airbag is disposed at the seat front side of the vehicle seat. At a time of a front collision of the vehicle, when a seat front-rear direction position of the vehicle seat is disposed further toward a rear side than a predetermined position, the foot airbag deploys between the knee airbag and the leg portions of the vehicle occupant seated in the vehicle seat, and restrains the leg portions of the vehicle occupant seated in the vehicle seat.
