A curtain airbag for a vehicle may include: a main chamber installed between a headliner and a vehicle body and provided to be downwardly unfolded to the interior of the vehicle; a diffuser being provided at an inlet portion of the main chamber connected with an inflator, formed with a first outlet and a second outlet which receive and discharge gas from the inflator; and an additional chamber connected with the second outlet of the diffuser and communicated with the second outlet to receive gas from the diffuser and inflated between the headliner and the vehicle body to separate the headliner from the vehicle body. In particular, the diffuser includes a joined portion to close partially or fully the first outlet, and the diffuser increases the gas supply to the main chamber when the joined portion is opened by an internal pressure of the diffuser.

Curtain airbag for vehicle

An air bag apparatus for a vehicle includes an inflator and a main tube configured to be unfolded toward an occupant of the vehicle by a gas pressure when the inflator explodes. A support tube is coupled to one side of the main tube and configured to be unfolded by being supplied with gas from the main tube. An active vent is configured to be installed in a path which connects the main tube to the support tube and to open and close the path. A controller is configured to control an opening and closing operation of the active vent.

Air bag apparatus for vehicle

A pedestrian air-bag for a vehicle may include a housing coupled to a lower end surface of a windshield side of a hood of the vehicle and having a cut line formed at an upper portion of a rear surface in the housing, and a hinge part formed at a lower portion, wherein the cut line and the hinge part forms an air-bag door, an air-bag module embedded in the housing, and a thermal damage preventing cover spaced apart from a lower portion of the housing, wherein the thermal damage preventing cover covers a lower surface and a front surface of the housing, and includes a rear end portion supporting the hinge part of the housing.

Pedestrian air-bag for vehicle

An active safety apparatus for vehicles and a method of controlling the apparatus, which can actively control the operation of a safety device, such as an airbag device or a seatbelt device installed in a vehicle for restraining a passenger behavior and protecting a passenger in a vehicle collision, based on the conditions of a vehicle collision and the passenger behavior which vary depending on the conditions of the vehicle collision, thereby optimally protecting the passenger for the conditions of the vehicle collision and improving passenger safety of the vehicle.

A system for controlling gas pressure in a dual-chamber airbag for vehicles, may include a cushion unit having an upper chamber and a lower chamber divided by a diaphragm therein, an inflator supplying gas to the upper chamber, and a unidirectional vent control member provided in the diaphragm and supplying the gas inside the upper chamber into the lower chamber in one direction.

System for controlling gas pressure in dual-chamber airbag for vehicles

A system and method are provided for vehicle passenger classification. The system may include a plurality of weight sensors installed under a seat frame to support a load of a vehicle seat, a single dummy sensor installed under the seat frame to support the load of the vehicle seat along with the plurality of weight sensors, and a passenger classification logic unit for classifying a passenger value obtained by summing sensor values of the plurality of weight sensors as either class 1 or class 2 by comparing the passenger value with a first reference and a second reference.

Vehicle passenger classification system using weight sensors

A vehicle airbag system may include an inflator supplying a gas to an airbag cushion, an airbag housing coupled with the inflator and having a housing vent hole to discharge a part of the gas supplied from the inflator, a retainer mounted in the airbag housing and coupled to the inflator, wherein the airbag cushion covers an opening of the retainer to supply the gas in the airbag cushion, the retainer including a guide hole and a retainer vent hole, and a tether connected to the airbag cushion at a first end portion thereof and fixed to the airbag housing at a second end portion thereof by passing through the guide hole of the retainer, wherein the tether includes a communication portion at the second portion thereof to form a hole therein so as to selectively permit an gas commutation between the airbag cushion and the outside through the retainer vent hole, the housing vent hole, and the hole of the communication portion.

Vehicle airbag system

A ramp apparatus for a curtain airbag for a vehicle, positioned between a headliner and a vehicular body panel such that the curtain airbag is deployed through a matching part formed between the headliner and a pillar trim, may include a support ramp fastened to the vehicular body panel and receiving a lower portion of the folded curtain airbag, and a deployment ramp extending from a first end of the support ramp to enclose a portion of the curtain airbag therein and deploying towards the interior of the vehicle to seal a gap between the vehicular body panel and the pillar trim by expansive pressure of the curtain airbag in the event of a vehicle collision.

Ramp apparatus for curtain airbag for vehicle

An apparatus for classifying a vehicle occupant to determine whether to deploy an airbag is disclosed. The classification apparatus includes a sensor which is installed in a seat of a vehicle and is supplied with AC power, the sensor having a sensing conductor and a guard conductor electrically connected to each other, with an insulator interposed therebetween. A controller compares an imaginary current value, attributable to variation in capacitance of the sensor, measured on an output side of the sensor, and a real current value, attributable to variation in resistance of the sensor, with preset threshold values, thus classifying an occupant who is sitting in the seat. According to the classification apparatus, even if moisture permeates into a seat, an occupant can be precisely classified using the real current value and the imaginary current value.
