One system may include: a first cutter configured to cut a first electrode sheet into a first electrode portion; a second cutter configured to cut a second electrode sheet into a second electrode portion having a second length; a winder configured to form an electrode assembly by winding the first electrode portion, the second electrode portion, a separator between the first electrode portion and the second electrode portion; and an identification information assigning device configured to assign identification information to the electrode assembly based on: a cut count value of the first electrode sheet and/or a cut count value of the second electrode sheet; and/or a position coordinate value of the first electrode sheet and/or a position coordinate value of the second electrode sheet.

Abstract: An air bag cushion for a vehicle. A tether reinforcing fabric coupled to a tether seam portion of a main cushion is used to allow the tether reinforcing fabric to inflate with the main cushion when the main cushion inflates, and the inflating tether reinforcing fabric forms an auxiliary chamber between the main cushion and the tether reinforcing fabric, and the auxiliary chamber of the tether reinforcing fabric supports the head of a passenger in a front passenger seat in the event of a crash, thereby preventing the rotation of the passenger's head and efficiently protecting the safety of the front passenger.

Abstract: An airbag cushion according to an embodiment may include a main body including a rear panel having a rear bonding line and a front panel having a front bonding line bonded to the rear bonding line and disposed to face a passenger when inflated by a gas introduced into an inner space formed between the front panel and the rear panel and a protruding chamber which is inflated and protrudes toward the passenger from the front panel, wherein the protruding chamber is provided with a folding structure in a state in which a part of the front panel is folded, and the folding structure is unfolded and inflated as the main body is inflated by the gas introduced into the inner space.

Abstract: An airbag cushion for a vehicle may include: a front panel disposed in a direction facing a passenger when the airbag cushion is inflated, and having a front sewed part formed along the edge thereof; and a rear panel coupled to the front panel so as to form a chamber therebetween, having a gas introduction hole to introduce gas into the chamber, and having a rear sewed part formed along the edge thereof, the rear sewed part being coupled to the front sewed part, wherein the rear sewed part has a curvature part formed in a curved shape at the portion coupled to the front sewed part.

Abstract: An airbag cushion is formed by combining a front panel and a rear panel, so the structure is simple and the number of parts is small. Accordingly, it is possible to reduce the manufacturing cost, the weight, and the volume, so the airbag cushion can be easily packed and manufactured. The airbag cushion is also configured to safely protect a passenger because it can be quickly unfolded and can be supported by a vehicle body part.

Abstract: Provided is a passenger airbag apparatus that not only allows an airbag cushion to inflate in different sizes, depending on the types and positions of passengers in a passenger seat, but can automate a folding process, because the airbag cushion is made in 2D. The passenger airbag apparatus according to an exemplary embodiment of the present invention includes: a passenger sensor detecting information on the type and position of a passenger in a passenger seat; a controller outputting control signal on the basis of the information supplied from the passenger sensor; a gas generator generating different amounts of gas in response to the control signal transmitted from the controller; and an airbag cushion connected with the gas generator, having a folded portion that is folded and bound, and inflating in different sizes while the folded portion is unfolded in accordance with the amounts of gas supplied from the gas generator.

Abstract: The present invention discloses a driver's air bag which can prevent a driver from being injured by a shock applied to the driver's chest at an initial stage of deployment because a portion corresponding to the chest of the driver is not fully deployed at an initial stage of the deployment of an air cushion by comprising: a cushion front surface to be brought into contact with a driver upon inflation of an air cushion; a cushion rear surface disposed at an opposite side of the cushion front surface, and having an inflator hole formed thereon; and first and second tethers which are disposed, spaced apart from each other, with respect to the inflator hole, and within the air cushion, with first ends thereof being fixed to the cushion front surface and second ends thereof being fixed to the cushion rear surface.

Abstract: A passenger air bag system for vehicles includes a cushion expanded to the front of a passenger when a collision of the vehicle occurs, an air bag housing mounted to an instrument panel at the front part thereof for accommodating the cushion therein, a retainer attached to the air bag housing for supporting the cushion, an inflator having the upper end vertically inserted into the rear part of the air bag housing in the normal direction thereof so that the inflator discharges gas to the cushion and the lower end fixed to the outer circumference of a cowl cross member, and an inflator bracket attached to the air bag housing for fixedly supporting the upper end of the inflator.
