Patent number: 11312326Abstract: The present invention relates to an airbag device for a vehicle. The airbag device comprises: an airbag cushion which is formed in a shawl shape and deployed toward both sides of a passenger so as to wrap and restrain the entire upper body around both shoulders of the passenger when a vehicle collides; and an inflator for generating gas and supplying the gas to the airbag cushion in response to an impact detection signal when the vehicle collides. Accordingly, when a vehicle collides, the shawl-shaped airbag cushion installed on the back of a seat is inflated and deployed to restrain the both sides and front area of the upper body of a passenger around both shoulders of the passenger, thereby safely protecting the passenger.Type: GrantFiled: April 5, 2019Date of Patent: April 26, 2022Assignee: Autoliv Development ABInventors: Nan-Young Oh, Hyun-Seop Lee, Dae-Chang Jung, Jong Ki Byun, Tae-Ik Gwon, Wan-Dong Yoo, Yong-Hyun Jung

Patent number: 11021130Abstract: A curtain airbag of a vehicle is provided adjacent to the roof of the vehicle in a folded state, is configured to have a shape that unfolds downward between an inner side surface of the vehicle and an occupant when the vehicle crashes, and includes an outer panel that proceeds toward the side surface of the vehicle and an inner panel that proceeds toward the occupant upon expansion. The curtain airbag further includes a head support part configured to have a shape in which an expansion thickness, which is defined by the outer panel and the inner panel in a portion that the head of the occupant contacts due to the car crash, gradually increases toward the front of the vehicle, so as to prevent the head of the occupant from rotating while moving toward the front of the vehicle. The curtain airbag may effectively stop the head of the occupant from rotating while moving toward the front of the vehicle during a vehicle crash.Type: GrantFiled: July 26, 2017Date of Patent: June 1, 2021Assignee: AUTOLIV DEVELOPMENT ABInventors: Tae Ik Gwon, Kyu Soung Jang, Wan Dong Yoo, Yong Hyun Jung, Hugh Finn, Gary Wootton, Dae Chang Jung

Patent number: 10933831Abstract: An airbag system for a vehicle is provided. The system includes an airbag cushion that is deployed from the upper portion of a seatback to cover the head of an occupant, thereby absorbing impacts applied to the head of the occupant and preventing neck bending attributable to movement of the head of the occupant. In addition, injury to the occupant is minimized by variably adjusting the deployment timing of the airbag cushion depending on the collision direction of the vehicle.Type: GrantFiled: November 27, 2018Date of Patent: March 2, 2021Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Jong Wook Kim, Wook Jin, Yong Tae Kim, Eung Man Kim, Wan Dong Yoo, Kim Dong Young, Yong Hyun Jung

Patent number: 8505966Abstract: An airbag module includes an airbag cushion, an inflator and a housing. The inflator injects gas into the airbag cushion when a vehicle is in collision, so that the airbag cushion is inflated and deployed. The housing houses the airbag cushion, which is folded before deployment, and the inflator. When the airbag cushion is deployed from the housing, the airbag cushion forms a hard chamber and a soft chamber that are defined by a partition. The hard chamber is supplied with gas by the inflator and is positioned in the upper front of the airbag cushion. The soft chamber is supplied with gas by the hard chamber via a connecting hole formed in the partition and is positioned in the rear of the airbag cushion. A vent hole for exhausting gas to the outside is formed in the soft chamber.Type: GrantFiled: April 19, 2010Date of Patent: August 13, 2013Assignee: Autoliv Development ABInventor: Wan-Dong Yoo

Patent number: 8398113Abstract: A knee air bag for a vehicle has an inflator, a diffuser and a cushion to protect a passenger's knee when the cushion is deployed. The knee air bag also includes an inflator connector which is provided on a back of the cushion, and an external tether which is provided on an upper portion of the inflator connector and secured at lower and upper ends thereof to the back of the cushion, thus guiding the cushion so that the cushion is deployed upwards. The knee air bag makes the cushion come into close contact with a seatback of the vehicle when the knee air bag is deployed, thus reducing interference with a roof air bag located at an upper position, therefore preventing a passenger's head or neck from suffering secondary injuries.Type: GrantFiled: June 27, 2011Date of Patent: March 19, 2013Assignees: Hyundai Motor Company, Kia Motors Corp., Autoliv Development ABInventors: Jun Yeol Choi, Wan Dong Yoo, Do Gwan Kim
