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.

The present disclosure relates to an airbag, and discloses an airbag support device and a control method thereof. The airbag support device includes an airbag cushion embedded in a side surface of a seatback and configured to be inflated and deployed forward from the seatback; a pop-up tether having one end connected to the seatback, and configured to be deployed in a direction in which the airbag cushion is deployed and to penetrate the airbag cushion; and a pop-up tether module provided on a side surface of a seat cushion, having the other end of the pop-up tether connected to an end of a tether pole, and configured so that the pop-up tether between the seatback and the tether pole is pulled while the airbag cushion is deployed to support the airbag cushion by the pop-up tether in a portion penetrating the airbag cushion.

A side airbag inflatable between an occupant of a vehicle seat and structure of the vehicle adjacent the vehicle seat. The side airbag includes a first airbag panel for being positioned facing away from the vehicle seat and a second airbag panel for being positioned facing the vehicle seat. The first and second panels define an inflatable volume of the side airbag. A tether assembly includes a first anchor panel attached to a first portion of the first airbag panel, a second anchor panel attached to a second portion of the first airbag panel, and a strap that interconnects the first anchor panel and the second anchor panel. The tether assembly is dimensioned and configured to limit movement of the first and second portions away from each other in response to inflation of the side airbag so that the side airbag assumes a curved shape when inflated.

The present disclosure relates to an airbag system which is operable to deploy in a vehicle crash event. The airbag system includes an airbag having an upper chamber, a lower chamber, an actuator, a tether, and an actuatable pin. In one example, the tether has a predetermined length and extends between the actuator and the lower chamber. The actuator is disposed at a predetermined lateral distance from the lateral chamber and is configured to inflate the upper chamber and the lower chamber to a predefined pressure. Furthermore, the actuatable pin is configured to maintain the tether in an indirect path when the airbag is not deployed and the actuatable pin is configured to allow the tether to have a direct path between the actuator and the lower chamber when the airbag is deployed.

An assembly for a vehicle includes an instrument panel. The assembly includes a steering wheel having a hub and a rim spaced from and supported by the hub, and an airbag supported by the hub and inflatable to an inflated position. The airbag in the inflated position has a rear panel extending from the hub to the instrument panel. The rear panel has a bowl shape that extends endlessly around the rim.

The present disclosure relates to a method for imaging an optical signal received by a graded index (GRIN) optical element to account for known variations in a graded index distribution of the GRIN optical element. The method may involve using a plurality of optical detector elements to receive optical rays received by the GRIN optical element at a plane, where the plane forms a part of the GRIN optical element or is downstream of the GRIN optical element relative to a direction of propagation of the optical rays. The optical rays are then traced to a plurality of additional specific locations on the plane based on the known variations in the graded index distribution of the GRIN optical element. A processor may be used to determine information on both an intensity and an angle of the received optical rays at each one of the plurality of specific locations on the plane of the GRIN optical element.

An airbag module for an automotive vehicle is disclosed. The airbag module comprises a folded inflatable airbag, a fastening element for mounting the airbag on the vehicle, a mounting jacket in which the folded airbag is received and fixed, as well as an elongate flexible holding strap for positioning the airbag in its deployed inflated state. The holding strap extends from a first strap end fastened on the airbag to an opposite second strap end to which the fastening element is attached. In the folded state of the airbag, the holding strap is connected to the mounting jacket or is received in the mounting jacket.

A vehicle occupant restraining device, comprising: a pair of air bags; an inner bag housed in at least one of the pair of air bags, is in communication with the at least one of the air bags, and is inflated and deployed inside the at least one of the air bags, on the sides of the body of a vehicle occu-pant; and a pair of pieces of tension cloth housed so as to extend along the respective sides of a housed pair of air bags, which are located on the opposite sides of the vehicle occupant, and then through the inside of the seat back of a seat into a seat cushion, wherein the inner bag completes inflation and deployment before the at least one of the air bags does, and the pair of pieces of tension cloth is deployed on the sides of the seat.

An airbag for a front passenger seat is configured to be inflated and expanded between the front passenger seat and an instrument panel. The airbag includes a main bag, a left sub-bag and a right sub-bag. The left sub-bag and the right sub-bag are respectively connected to a left side portion and a right side portion of the main bag. The left sub-bag and the right sub-bag are connected to each other on at least one of an upper portion, a lower portion and a front portion of the airbag.

Provided is a curtain air bag device including a cushion body provided with a main cushion part and a cushion moving part that is inflated by gas injected from an inflator when the cushion body is deployed and presses the main cushion part in a desired direction, a strap part configured to bind the cushion body such that the main cushion part and the cushion moving part keep a folded shape and to be broken when the cushion body is deployed, and a mounting part connected to the cushion body and coupled to a vehicle body.
