A superconducting motor system includes a stator and one or more rotors inside the stator. The rotors may form a plurality of poles, and may rotate when a current is applied thereto. The one or more rotors include: a superconductor winding portion for each pole and in which superconductor coils are wound to form at least two layers; a power supply portion configured to supply a current to the superconductor winding portion; and a resistor portion connecting the superconductor winding portion at least partly in parallel to the power supply portion. the resistor portion enables different currents to be able to flow through the at least two layers of the superconductor winding portion.

Superconducting motor system

A roof-mounted airbag includes a cushion having a first chamber and a second chamber deployed downward from a vehicle roof while being inflated toward passengers facing each other, and a support chamber deployed between the first chamber and the second chamber and configured to push intermediate portions of the first and second chambers toward the passengers facing each other.

Roof-mounted air bag

An airbag device and a method for controlling deployment of the same are proposed. The airbag device is configured to protect a passenger by controlling an airbag cushion deployed toward the rear space of a seatback in an event of a vehicle collision, and the airbag device includes an airbag cushion deploying toward the rear space of the seatback, a sensor part detecting a seating status and a seating posture of a passenger with respect to each seat, and a controller, in an event of a collision, configured to change and control a deploying status of the airbag cushion and an inflation amount of the airbag cushion in response to the seating status and the seating posture of the passenger.

Airbag device and method for controlling deployment

A motor that is a wound field synchronous motor and includes a rotor and a stator. The rotor includes a plurality of winding portions configured to have a preset cross-section for generating a uniform effective air gap. The winding portions are spaced from each other a predetermined distance apart along a circumferential direction of the rotor. A field coil is wound around the plurality of winding portions.

Motor

A motor includes a stator on which an armature coil is wound, a rotor disposed inside the stator, a superconducting field coil being wound thereon and, a controller configured to control the motor, in which the controller is configured to control an armature current supplied from an AC source to the armature coil and a field current supplied from a DC source to the field coil, and charge at least a certain ratio of the field coil before starting the motor.

Motor and method of controlling the same

An airbag device includes a first chamber configured to be deployed in a shape that surrounds a first side and a front side of a seat, a second chamber configured to be deployed in a shape that surrounds a second side and the front side of the seat and fastened to the first chamber at a first portion at which the second chamber overlaps the first chamber, and side tethers connected to one of or both of a second portion between the first chamber of an airbag module embedded at first side of a seatback and a third portion between the second chamber of an airbag module embedded at the second side of the seatback.

Airbag device

Provided is a roof-mounted airbag configured to reduce the risk of injury to a passenger by minimizing movement of a cushion when the passenger is placed on the cushion. The roof-mounted airbag includes a cushion, formed in a cylindrical shape and configured to be deployed downwards between passengers facing each other while left and right upper ends thereof are fixed to a roof part, and an inflator configured to provide gas to an inside of the cushion.

Roof-mounted airbag

Disclosed are a shoulder airbag and an airbag cushion thereof that are capable of restricting an occupant from being moved upward along a seatback and from being abruptly pushed in a direction away from a collision side of a vehicle when vehicle collision occurs, thereby safely protecting the occupant. The shoulder airbag includes an airbag cushion mounted in a seatback and configured to be deployed so as to cover each of the shoulders of an occupant sitting in a seat in three axis directions.

Shoulder airbag and airbag cushion thereof

The present disclosure describes a roof airbag apparatus for a vehicle which protects the occupant seated in the cabin in such a manner that the roof airbag is deployed downward from the cabin roof, and safely protects the occupant from impact in such a manner that the occupant is securely restrained by the airbag as the deployment shape of the airbag is maintained.

Roof airbag apparatus for a vehicle

An airbag cushion for installation in a negative pressure vehicle having a partition extending vertically along B-pillar trim covering a B-pillar, may include a cushion body mounted on a vehicle body in a folded state on an upper portion of the B-pillar, inflated by gas, and deployed between the B-pillar trim and the partition, and a tether connecting one side of the cushion body to the vehicle body to allow the cushion body to maintain its deployed shape.

Airbag cushion and curtain airbag device

The present invention relates to a deployment guide mechanism for a roof airbag device that enhances assembly performance and productivity of the product by improving an assembly structure of a guide wire and a spring. The present invention discloses a deployment guide mechanism including a guide wire fixed to one side of a roof portion and provided in the lengthwise direction in which the roof airbag deploys, a guide housing fixed to the other side of the roof portion, a stopper supported in the guide housing and coupled to an end of the guide wire in a threaded coupling structure, and an elastic member providing an elastic restoring force to the stopper in the lengthwise direction of the guide wire toward the other side of the roof portion.

Roof airbag device

A roof airbag for a vehicle is proposed. The roof airbag for a vehicle has an airbag cushion configured to be unfolded downward from an inner roof to protect a passenger seated on a seat, and the airbag cushion has a shape bent toward the passenger by a main tether and a sub-tether, thus securing a restraining force for the passenger and safely protecting the passenger from an impact, and the airbag cushion is unfolded downward while avoiding insertion between a roof-side portion of the roof and a headlining by the sub-tether. Specifically, the airbag cushion is prevented from being transversally contracted and an unfolding shape of the airbag cushion is maintained. Furthermore, the fluidity of a gas flow in the airbag cushion is secured, so that the airbag cushion is rapidly unfolded.

Roof airbag for vehicle

An airbag device includes a tether having an improved folding position that enables the tether to unfold as it cuts through a covering. The airbag device may include a foam pad embedded in a seatback, an airbag cushion folded at a lateral side of the foam pad and configured to be deployed forward, a covering shaped to cover the foam pad and configured to cover the seatback, and a tether positioned between the foam pad and the covering and connected between the seatback and the airbag cushion. The tether is configured to unfold as it cuts through the covering when the airbag cushion is deployed.

The present invention relates to an external airbag device optimized in design to reduce collision energy to be applied to a vehicle and safely protect a pedestrian, and the external airbag device includes deployment guides provided in an up/down longitudinal direction of a vehicle, and an airbag cushion configured to be deployed along the deployment guide and cover an outer surface of the vehicle.

External airbag device

A roof airbag for a vehicle includes: an airbag cushion located at a roof panel of the vehicle and configured to be unfolded from a first side portion to a second side portion of the roof panel during an operation of the airbag cushion; a first seam portion extended in a direction intersected with an unfolded direction of the airbag cushion and allowing upper and lower surfaces of the airbag cushion to be in contact with each other; and an inflator coupled to the first side portion of the roof panel, and connected to the airbag cushion and configured to inject gas into the airbag cushion so as to allow the airbag cushion to be unfolded from the first side portion to the second side portion of the roof panel.
