Provided is a curtain airbag apparatus capable of preventing a head of an occupant from being moved forward at the time of an oblique collision of the vehicle. To this end, a curtain airbag apparatus according to an exemplary embodiment of the present invention includes: an auxiliary airbag which is coupled to the curtain airbag, is inflated when gas flows into the auxiliary airbag, and protrudes into the interior of a vehicle; and a support panel which is coupled to the curtain airbag and the auxiliary airbag, and supports the protruding auxiliary airbag.

An airbag includes a manifold having an outer panel and an inflation chamber defined at least in party by the outer panel. The airbag further includes a first compartment and a second compartment spaced from the first compartment connected to the outer panel and positioned external to the inflation chamber. A first one-way valve is in fluid communication with the manifold and the first compartment, and a second one-way valve is in fluid communication with the manifold and the second compartment.

A vehicle side curtain airbag device having front protection function, comprising a side airbag (1) and an auxiliary airbag (2) connected to one side surface of the side airbag (1) and arranged in a left/right transverse direction after being expanded; a dividing hole membrane (3) is disposed between the side airbag (1) and the auxiliary airbag (2); the dividing hole membrane (3) is ensured to be opened only when the internal pressure of the side airbag (1) reaches a certain value, thus realizing self-adaptive opening threshold adjustment, controlling the instant of inflation and inflation speed of the auxiliary airbag (2), and adjusting the stiffness of the auxiliary airbag (2). When a vehicle has a collision, the device protects the head and neck of a passenger in both side collision and front collision traffic accidents, thus effectively absorbing the collision impact energy of the passenger, and reducing injury to the passenger.

An airbag includes on the rear plane a passenger protection portion for protecting a front seat passenger. The passenger protection portion includes a front-collision arresting plane for protecting a head of the passenger as he moves forward in the event of a frontal collision of the vehicle and an oblique-collision arresting plane that is disposed at least either on the left or on the right of the front-collision arresting plane in such a manner as to protrude rearward out of the front-collision arresting plane for protecting the head of the passenger as he moves diagonally forward in the event of an oblique or offset collision of the vehicle. The passenger protection portion further includes an arresting recess that is disposed between the front-collision arresting plane and oblique-collision arresting plane in such a manner as to be sunken forward for receiving and arresting the head of the passenger.

A pre/post-tensioning controller system for a wheelchair tie-down and occupant restraint system (“WTORS”) will be a comprehensive energy management system for controlling excessive excursions of a wheeled mobility device during various adverse driving scenarios. The system uses multiple pre-tensioning and post-tensioning events during a front, side, or rear impact crash or rollover scenario—and effectively controls excursions by the tensioning of the WTORS equipment at specific and ideal moments. The system also uses tensioning events on the tie-down equipment during a long duration turn or other aggressive maneuvers. The system may also use tensioning events on the occupant restraints. The energy management system can be adapted for use with traditional four-point tie-downs and newer three- and two-point tie-down systems that incorporate fixed or movable bumpers, as well as compressive-type securement systems, and other systems as well, including docking systems.

An airbag is configured by six base materials of two side wall configuration panels, a projecting portion configuration panel, a front panel, and two rear panels. Each of the side wall configuration panels configure a left wall portion or a right wall portion facing each other on a side in a rightward-leftward direction in a main body inflation portion, and a projecting portion configuration portion configuring a projecting inflation portion is located in one of the side wall configuration panels. The front panel configures a region from an upper wall portion to a lower wall portion, which face each other on a side in an upward-downward direction in the main body inflation portion. Each of the rear panels configures a rear surface in the main body inflation portion when the main body inflation portion is completely inflated. The projecting portion configuration panel has an external shape substantially coincident with that of the projecting portion configuration portion. The projecting portion configuration panel and the rear panel on the projecting inflation portion side include a recess portion configuration portion configuring a restraining recess portion.

A front airbag (10) includes an inflatable chamber (18) having a baffle surface (16) provided to cushion an occupant (14) to be restrained, wherein a tether (28) extending inside the inflatable chamber (18) is provided which, when the front airbag (10) is mounted on the vehicle and is inflated, extends obliquely with respect to a vehicle longitudinal direction (L) and which is fastened with a first longitudinal end (34) to a single baffle surface-side fastening point (30) at the baffle surface (16).

A seat airbag apparatus for a vehicle is disclosed. A side cushion is deployed so as to protrude forward from a seatback in order to protect the lateral sides of an occupant, and a front cushion is deployed so as to protrude from the side cushion to the front of the occupant in order to protect the front side of the occupant. The deployment of the side cushion and the front cushion is limited by an upper dual-surface tether structure, formed by an upper-side surface tether and an upper-front surface tether, and a lower dual-surface tether structure, formed by a lower-side surface tether and a lower-front surface tether, thereby increasing force with which movement of the occupant is restricted, thus further enhancing an occupant protection effect.

A side air bag apparatus for a vehicle. The side air bag apparatus includes: a first cushion configured to cover and protect an upper body area of a passenger who has adopted a relax mode while tilting rearward a seatback; a second cushion configured to cover and protect a head area; and a valve member configured to open and close a vent hole connecting the first cushion to the second cushion. Accordingly, both the upper body area and the head area of the passenger in the relax mode are efficiently and sufficiently protected.

An airbag uses a rear surface side when inflated as an occupant protection section. The occupant protection section includes a frontal collision restriction surface, oblique collision restriction surfaces on left and right sides of the frontal collision restriction surface, and restriction recessed portions between the frontal collision restriction surface and each oblique collision restriction surface. A recessed portion tether links a tip end side of a recess of the restriction recessed portions and a front end side of the airbag to each other to the inside thereof, and when inflated, at the time of dividing the region into two in the left-right direction around the vicinity of the attachment center to the storage part, provides a remote side region on a side away from a driver seat and a driver seat side region. The capacity of the remote side region is smaller than the driver seat side region.
