A seat airbag apparatus for a vehicle and a method of controlling the operation thereof, includes side cushions deployed from the seatback, front cushions configured to be deployed from the side cushions, and inflators for the side cushions and inflators for the front cushions. The deployment operation of the side cushions and the deployment operation of the front cushions are respectively controlled depending on a normal seating mode and a relax mode of an occupant and a side collision and a front collision of the vehicle.

A passenger protection apparatus for vehicle includes an airbag, a tether, a tension member, and a controller. The airbag is configured to deploy via a seat on which a passenger sits or a periphery member of the seat. The tether has a first end coupled to a front portion of the airbag in a deployment direction of the airbag. The tension member is coupled to a second end of the tether and configured to pull the first end to the seat side. The controller is configured to activate the tension member to pull the tether at the same time as the airbag deploys, when the airbag is deploying, or after the airbag has deployed.

An airbag system includes a main airbag device that is provided in front of an occupant and that includes a first bag body, a seat airbag device that is provided in the vehicle seat and that includes a second bag body which is configured to be deployed by being inflated toward at least sides and a front of a torso of the occupant at behind the first bag body and which is configured to restrict the occupant to the vehicle seat, and a seat displacement mechanism that is configured to release restriction by a lock section that restricts movement of the vehicle seat and that is configured to displace the occupant toward the first bag body in front in a case an input impact is equal to or larger than a predetermined strength.

An airbag device equipped in a vehicle seat. The vehicle seat has a structure in which a seat frame is arranged with left and right sides inside the seat back. The airbag device according to the present invention includes: an inflator that is secured to the side of the seat frame of the vehicle seat and an airbag that is stowed inside the seat back in an elongated and compressed state and is expanded and deployed by the expansion gas discharged from the inflator. The airbag in the stowed state is arranged along the seat frame, and includes a lower portion area lower than the inflator and an upper portion area above the inflator. The lower portion area is arranged inside the seat frame, and the upper portion area is arranged outside the seat frame.

Provided is a side airbag for side collision which is deployed between two seats in a width direction of a vehicle to prevent occupants siting on the two seats from colliding with each other. The airbag includes a chest protective area to protect a chest of an occupant; a head protective area extending upward from the chest protective area to protect a head of the occupant; and a support area extending rearward from the head protective area and making contact with a head rest, which is provided on an upper portion of a back of the seat, so as to be supported by the head rest, wherein, the support area of the airbag is supported by the head rest when the vehicle collision occurs to prevent a head of an occupant who sits near a crashed side from moving rearward of the head protective area, thereby preventing the head of the occupant sitting near the crashed side from colliding with a head of a counterparty occupant who faces the occupant sitting near the crashed side in the width direction of the vehicle.

A child seat includes a seat portion, a backrest frame and a front guard respectively connected pivotally with the seat portion, a latch connected with the seat portion, and a linking part respectively coupled to the latch and the backrest frame, wherein the latch is operable to lock the front guard in position, the latch being engaged with the front guard for locking the front guard and disengaged from the front guard for unlocking the front guard, and the backrest frame being rotatable to cause the latch to unlock for rotation of the front guard.

An airbag for a vehicle is provided. The airbag includes an airbag cushion that has a plurality of chambers and the plurality of chambers are connected to be interlocked with each other by an operation tether. Accordingly, when an occupant presses against a specific chamber due to a vehicle collision, the other chamber is deformed to wrap the occupant, thereby restraining the occupant in a seat and minimizing the occurrence of injury.

A passenger protection apparatus for vehicle includes an airbag and a regulating member. The airbag is capable of deploying forward or upward from a side of a seat on which a passenger sits. The regulating member is capable of regulating deployment of the airbag. The regulating member connects a side of a seat back to a side of a lower part of the seat, and is configured to contact an outside of the airbag in a seat width direction to regulate a deployment direction of the airbag to deploy the airbag inward in the seat width direction.

A seat airbag for a vehicle is installed in a side part of a seat back and an airbag cushion thereof is deployed forward. A front portion of the cushion is divided into a head chamber disposed at an upper location, a chest chamber disposed at a central location and a pelvis chamber disposed at a lower location. The airbag protects a vehicle occupant while wrapping around the occupant with use of a first tether to a fourth tether that are integrally formed into a single string and connect the respective chambers to each other.

A monument mounted airbag system for arresting passenger movement during a sudden acceleration/deceleration event of a moving vehicle includes an airbag assembly including at least one airbag on a first portion of a monument structure, the airbag assembly having a housing at least partially defined by a space between an external member and the monument structure.
