Disclosed herein is an airbag apparatus that includes a pair of main cushions installed to respective left and right sides of a seat back and deployed forward when gas is delivered to an internal filling chamber, to restrain a passenger from sides, and a pair of auxiliary cushions coupled to respective front ends of the main cushions while in communication with the main cushions and deployed laterally at one ends thereof to restrain the passenger from a front.

A safety system includes an airbag configured to deploy from a rail and restrain motion of an occupant, a tether configured to deploy from a pillar, and an anchor coupling the tether and the airbag. The anchor is configured to travel from a stowed position proximate to the rail to a deployed position spaced apart from the rail and spaced apart from the pillar in unison with deployment of the airbag. The safety system includes a tensioning mechanism configured to apply force to the tether. Motion of the anchor is controlled by the force applied by the tensioning mechanism.

A tether actuation unit includes an actuator configured to form a connection with a tether that is releasable in response to actuation of the actuator, and a housing configured to receive the actuator. The housing includes a tether channel configured to allow the tether to extend therethrough. The tether channel includes sidewalls configured to receive and engage the tether along a portion of its length when the tether extends at an angle from the housing. The sidewalls of the tether channel are configured to limit movement of the tether in response to airbag deployment in order to limit tension applied to the actuator by the tether to a predetermined range of non-orthogonal directions with respect to a central axis of the actuator.

A curtain airbag apparatus for a vehicle is configured to connect a curtain airbag cushion to a vehicle body by a cushion restriction device including a tether carriage and a cushion tether to reinforce a restriction force of the deployed curtain airbag cushion, and to reinforce restriction on movement of an occupant during a side collision by use of the curtain airbag cushion having the reinforced restriction force to prevent the occupant from being thrown through a vehicle side window during a side collision even when a panorama window is used as the side window.

Provide an airbag device for a vehicle with a simple structure having improved occupant restraint performance and improved safety.

The airbag cushion includes a gas discharge section, a first tether, and a chamber having an occupant side panel and a steering wheel side panel. The first tether includes a first end directly or indirectly connected to the occupant side panel and second ends connected to the steering wheel side panel. The edge of the gas discharge section can be pulled into the chamber by the taut first tether and the area of the gas discharge section opening with the edge of the gas discharge section pulled into the chamber is smaller than when the first tether is relaxed.
