A roof airbag apparatus for a vehicle in which an airbag deploys downward from the interior roof and protects occupants seated in seats and the airbag has a bending shape by a tether so that the restraint on occupants is secured and the occupants are safely protected.

An apparatus helps to protect an occupant of a seat of a vehicle including an instrument panel and a display screen that is positioned rearward of an occupant facing surface of the instrument panel and that extends vertically above an upper surface of the instrument panel. The apparatus includes an airbag configured to have a stored condition in which the airbag is rolled and/or folded and positioned within the instrument panel at a location below the display screen. The airbag is configured to inflate and deploy from the instrument panel in response to receiving inflation fluid from an inflation fluid source. The airbag is configured to deploy in an upward direction through a space between the occupant and the instrument panel to a position in which the airbag is positioned between the display screen and the occupant.

A vehicle side airbag device including an inflator, a side airbag, and a duct is installed at a side section on a vehicle width direction outer side of a seatback of a vehicle seat configured to restrain an occupant using a three-point seatbelt. The side airbag receives a supply of gas from the inflator in a vehicle side-on collision. As a result, a waist chamber is inflated and deployed from a lower portion of the side section toward a side of a waist of the occupant, and a head chamber is inflated and deployed from an upper face side of the side section toward a side of a head of the occupant. The duct extends along a vertical direction of the side airbag inside the side airbag, and is configured to guide gas from the inflator into the waist chamber and into the head chamber.

A vehicle safety system for helping to protect an occupant of a vehicle seat includes a seatbelt extensible around the occupant to help restrain the occupant in the vehicle seat. The seatbelt includes a lap belt configured to extend across the occupant at the hips. An airbag is secured to the lap belt and configured to inflate and deploy upward from the lap belt to a deployed position in front of the occupant. The system is configured to adjust the deployed position of the airbag in response to the position of the occupant.

The invention relates to an airbag (14) for unfolding between a vehicle part (10) and a vehicle occupant (18), comprising an impact wall (20) which, in the installed and unfolded state of the airbag (14), faces a vehicle occupant (18) and a circumferential wall (22) which is connected to the impact wall (20) and, in the installed and unfolded state of the airbag (14), extends between the impact wall (20) and the vehicle part (10), wherein the circumferential wall (22) is made with multiple layers, at least in some sections, and forms at least one annular tube (23) which delimits an annular inflatable first airbag volume (V1), and wherein a radially inner layer (26) of the circumferential wall (22), together with the impact wall (20), delimits an inflatable second airbag volume (V2) that is separate from the first airbag volume (V1). The invention further relates to an airbag module (12) having such an airbag (14).

A curtain airbag capable of improving deployability of an airbag cushion without including a ramp component. The curtain airbag includes a main cushion, provided at an upper side of a pillar of a vehicle along a forward-and-rearward direction of the vehicle and configured to be deployed with inflation thereof, and a guide cushion, connected to a front area of an upper end portion of the main cushion and configured to extend toward a rear of the vehicle, the guide cushion pushing the main cushion toward an inside of the vehicle while being inflated together with the main cushion.

[Problem] To provide an airbag apparatus in which the injury value of a passenger can be efficiently suppressed in an emergency. [Resolution Means] A typical configuration of an airbag apparatus 100 according to the present invention includes: an inflator 118 which is installed in a vehicle so as to be capable of supplying gas; an inner bag 112 which is expanded from in front of a seat utilizing the gas; and an outer bag 110 to which the gas is supplied from the inflator 118 or via the inner bag 112 and expanded so as to surround the inner bag 112. The outer bag 110 includes an opening 116 which exposes the inner bag 112 towards the seat 104, wherein the inner bag 112 has a more elongated shape in the anteroposterior direction of the vehicle than in the width direction of the vehicle, and the inner bag 112 further includes a restraining part 114 which is exposed on the recessed surface from the opening 116 to the seat side.

A roof-mounted airbag includes a cushion having a first chamber and a second chamber deployed downward from a vehicle roof while being inflated toward passengers facing each other, and a support chamber deployed between the first chamber and the second chamber and configured to push intermediate portions of the first and second chambers toward the passengers facing each other.

A vehicle center airbag may include a main cushion and a plurality of sub-cushions. The main cushion is mounted on a lateral surface of a seat back and is deployed in a forward direction, being positioned beside a passenger when a side collision occurs. The sub-cushions are configured to communicate with the main cushion and are deployed upwards from the top portion of the main cushion. When the sub-cushions are deployed, they extend in a forward-backward direction of the vehicle and are positioned above the torso of the passenger.

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.
