An actuator of an airbag device includes a main body portion, which is attached to an attachment base, and a cap including a fitting protruding portion that is inserted into a fitting recessed portion of the main body portion. The fitting protruding portion has a holding portion, which is inserted into a holding hole of a coupling member when fitted to the main body portion and holds a leading end portion of the coupling member, and a movement permitting unit that, when a ceiling portion of the cap is subjected to pressure of a combustion gas of a squib, causes the ceiling portion to move, and causes the holding portion to move from a holding position, wherein the holding portion is inserted into the holding hole of the coupling member, to a holding released position, wherein the holding portion is removed from the holding hole.

A frontal airbag for vehicle occupants comprises a contact panel (26) facing the vehicle occupant in the inflated state. Inside the airbag tension means (30, 30′) which restrain portions of the contact panel (26) in the inflated state of the frontal airbag (10) are arranged on the contact panel (26) so that, in the mounted and inflated state, the contact panel (26) forms plural indentations (32) extending vertically from the view of the associated occupant. The frontal airbag (10) optionally may take a first completely inflated state and a second completely inflated state with a larger airbag volume than in the first state, wherein a release device (40) is assigned to at least several of the tension means (30, 30′) and, when the release device is not activated, the frontal airbag (10) only reaches the first state and, when the release device (40) is activated, the contact panel (26) bulges in the area of the released tension means (30, 30′) further toward the occupant so as to enable the second state.

An airbag apparatus for reducing an injury may include: an airbag cushion part having a vent hole part through which gas is discharged; a cover member having a communication hole part smaller than the vent hole part, and adjusting the amount of gas discharged through the vent hole part by selectively covering the vent hole part; and a vent tether connected to the airbag cushion part and the cover member, and pulling the cover member in connection with an expansion of the airbag cushion part.

An airbag module including a first casing enclosing a first gas space, a first inflator and a control device for controlling ventilation of the first gas space or the shape of the first casing. The control device includes a second casing (42) enclosing a second gas space and a gas source. The second gas space is bordered by a permanent edge connection, and further includes a control element such as a strap (60), whose first end is connected to the first casing and whose second end is sewn to the second casing (42) by a tear seam (49), and is decoupled from the second casing (42) upon filling of the second gas space. The tear seam (49) touches or intersects the edge connection at two points so that the tear seam divides the second gas space into two regions (43a, 43b).

An airbag module comprising an airbag (50) having a passive adaptive vent on a rear panel of the airbag, the vent having a movable vane which when moved causes the vent (200) to change state from open to closed or from closed to open, the airbag further including a main tether (100) secured to a face panel (54) of the airbag, the main tether moving with the face panel, the main tether having an opening (130) into which is threaded a portion of a control tether (80), the control tether is connected to the vane (210) and to the face panel, wherein movement of the end of the control tether in a first direction generally that of the inflating air bag causes the other end of the control tether secured to the vane to be moved in a direction different than the first direction

A center airbag device may include: an inflator positioned between first and second seats, and generating an operating gas; a chamber part receiving the operating gas generated by the inflator, and expanding between the first and second seats; an internal tether part positioned in the chamber part, and connected to one or more of the top and side surfaces of the chamber part so as to control the deployment shape of the chamber part; and a locking release part connected to the internal tether part, and removing a restriction of the internal tether part according to a control signal.

An airbag device includes an airbag having an exhaust hole and a flap member that can close off the exhaust hole. The flap member includes a flap main body and a coupling member. The leading end of the coupling member is coupled with an opening/closing control device. The flap main body closes off the exhaust hole from an inner peripheral face side of the airbag. A width on the base portion side is set to be greater than a width of the exhaust hole. Whole of the base portion side is joined to the peripheral edge of the exhaust hole in the airbag. The flap main body covers the exhaust hole in a region between straight lines that connect one end each of a joint region on the base portion and a region on the leading end to which the coupling member is caused to be coupled.

An apparatus for helping to protect a vehicle occupant includes an airbag having primary and secondary chambers fluidly connected by a first passive vent and an active vent having an open condition and a closed condition. The primary chamber has a stored condition and a deployed condition to cover a portion of the vehicle. An interior panel divides the primary chamber into upper and lower inflatable volumes and includes a second passive vent fluidly connecting the upper and lower inflatable volumes. The secondary chamber has a stored condition and a deployed condition to cover portions of the vehicle left uncovered by the primary chamber. An inflator is actuatable to provide inflation fluid to the primary chamber. The active vent is controllable to prevent fluid communication between the primary and secondary chambers in response to occupant penetration into the primary chamber and controllable to allow fluid communication between the primary and secondary chambers in response to occupant penetration into the secondary chamber. The second passive vent automatically closes to prevent fluid flow from the lower inflatable volume to the upper inflatable volume in response to occupant penetration into the secondary chamber.

Embodiments of the present disclosure relate to a vehicle seat airbag apparatus, wherein: when a side collision accident occurs, an active vent hole is closed to delay the deployment speed of a front cushion and thus to enable a side cushion so as to have sufficient internal pressure, thereby improving ability to respond to a side collision; and when a frontal collision accident occurs, the active vent hole maintains an open state to rapidly deploy the front cushion, thereby improving ability to respond to a frontal collision.

An airbag, in particular a front airbag, includes an outer wall having a front wall and a rear wall (18, 24) and a tether (16) as well as an electrically actuatable activation unit (26) for releasing the tether (16). The tether (16) includes plural tether portions (30, 32) connected to each other via a first tear seam (36). A tension means (40) is coupled to the tether (16) so that is destroys the first tear seam (36) when the activation unit (26) is not actuated.
