Abstract: A roof airbag device includes an outer cushion and an inner cushion. The outer cushion includes a left wing part and a right wing part, which are oppositely disposed about the passenger's head, an upper cushion part connecting the left and right wing parts, and an outlet hole through which an inflation gas from an inflator is transferred. The inner cushion is disposed between the left and right wing parts, and has an inlet hole through which the inflation gas is supplied, and a discharge hole through which the inflation gas is discharged.

Abstract: A center curtain air bag apparatus for a vehicle efficiently protects a rear seat passenger with an air bag cushion that is deployed during a car collision accident.

Abstract: Disclosed herein is a method for handover of a mobile terminal. In the method, a group of mobile terminals for handover is formed by grouping a plurality of mobile terminals. A first terminal of the group scans a target base station. One or more other terminals of the group perform handover to the target base station using the scan information of the first terminal.

Abstract: 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.

Abstract: An airbag apparatus for a vehicle may include an inflator, and an airbag cushion having a depressed head support portion formed in a rear portion of the airbag cushion so that when the airbag cushion may be deployed by gas supplied from the inflator, the head support portion receives a head of a passenger, and shoulder support portions protruding from lateral sides of the head support portion in a rearward direction and forming a space between the shoulder support portions to have the head support portion therebetween when the airbag cushion may be deployed, and a support tether provided in the airbag cushion and extending in a transverse direction across the shoulder support portions such that a gas path may be defined in a front portion of the airbag cushion below the support tether, the gas path guiding the gas downwards.

Abstract: Disclosed herein is a curtain airbag cushion. The cushion has a length appropriate for being deployed to the chest of a passenger. A blocking part which partitions the interior of the cushion into portions is oriented in the vertical direction. The lower end of the blocking part is spaced apart from the bottom of the cushion by a predetermined distance. Thus, when an inflator explodes, gas discharged from the inflator is guided towards the lower portion of the cushion and then guided towards the front or upper portion of the cushion through the space between the lower end of the blocking part and the bottom of the cushion.

Abstract: A pre-crash side airbag device includes a side collision detection sensor, a pre-crash sensor, a main airbag, an auxiliary airbag, and a control unit. The side collision detection sensor detects a collision occurring at the side of a vehicle. The pre-crash sensor detects physical quantities related to the speed of an approaching object. The main airbag is deployed when a control signal is input. The auxiliary airbag is coupled to one side of the main airbag. The control unit controls the deployment of the main airbag and the auxiliary airbag depending on a pre-crash case where a high-speed side collision is expected and a normal case where a low-speed side collision is expected or the measurement value is erroneous.

Abstract: A passenger seat air-bag module, may include a cushion plate on which an air-bag cushion is provided, the cushion plate mounted to a vehicle body, an inflator unit secured to the cushion plate and providing gas pressure to the air-bag cushion, and a seat cover secured at a first side thereof to the inflator unit and the cushion plate and secured at a second side thereof to the cushion plate to cover an outer portion of the air-bag cushion.

Abstract: An internal airbag device may include an inflator, an airbag housing mounted in a roof in a region between a front seat and a rear seat, and an airbag received in the airbag housing to deploy downwards by gas supplied from the inflator, wherein the airbag includes a horizontal airbag section supported by the roof during the gas may be supplied therein in a deployment thereof, and a vertical airbag section fluid-connected to the horizontal airbag section and extending downwards from an end of the horizontal airbag section opposite the rear seat in a deployment thereof.

Abstract: An airbag apparatus for a vehicle may include an inflator; a housing installed in a roof, and a cushion contained in the housing and configured to be deployed downwards by a gas discharged from the inflator to protect an occupant in the vehicle, wherein an upper surface of the cushion is supported by the roof when the cushion is in a deployed state, and a front surface of the cushion extends in a rear direction of the vehicle in an inclined shape to form a recess to prevent interference with a seatback of the front seat while the cushion is deployed downwards.

Abstract: Disclosed herein is an asymmetrically expanding airbag cushion for a vehicle, which is inflated when airbag gas flows from an inflator through a gas hole to an interior of a cushion bag as a result of a vehicle collision. The airbag cushion includes a central expansion portion, a lower expansion portion and an upper expansion portion. The central expansion portion is provided on the central portion of the cushion bag to communicate with the gas hole. The lower expansion portion is surrounded by a lower sewing line which is open at a lower portion, and positioned under the central expansion portion. The upper expansion portion is surrounded by an upper sewing line which is open at an upper portion, and positioned above the central expansion portion. The central, lower and upper expansion portions are sequentially inflated when the airbag gas flows into the cushion bag.
