An airbag device has a first side cushion that expands forward to cover one side of an occupant seated in the seat of the vehicle, a second side cushion that expands forward to cover the other side of the occupant, at least one inflator that injects gas to inflate the first side cushion and the second side cushion, and a connection that connects the first side cushion and the second side cushion. The connecting part is deployed so as to pass through the rear surface region between the seatand the occupant above the seat surface of the seat in the fully expanded state when the expansion and deployment of each side cushion and is complete, and is held in place by the occupant, pulling each side cushion and inward.

Airbag device

An airbag device installed in a vehicle seat having a seat cushion forming a seat surface and a seatback forming a backrest, being provided with an inflator stowed in one side portion of the seatback that generates inflation gas, and an airbag stowed in the seatback in a rolled or folded state that deploys from one side portion by the inflator releasing the inflation gas. The airbag deploys toward the front of the seatback and includes an upper chamber region for protecting at least around the head and neck of the occupant and a lower chamber region for protecting mainly from the waist to the shoulders of the occupant.

An airbag device includes a driver airbag cushion and a curtain airbag cushion. The curtain airbag cushion includes a first seam portion formed so as to extend vertically within a range in which the driver airbag cushion is projected outward in the vehicle width direction, a first chamber expanding so as to be thicker in the vehicle width direction than the first seam portion on the front side of the first seam portion, and a second chamber expanding so as to be thicker in the vehicle width direction than the first seam portion on the rear side of the first seam portion. The driver airbag cushion is expanded and deployed in a state separated from the first chamber while being in contact with a curved portion of the second chamber that is curved toward the first seam portion.

The present invention is an airbag device equipped in a vehicle seat having a seat cushion forming a seat surface and a seatback forming a backrest, containing: an inflator; and an airbag that is stowed in the seatback and deployed by the expansion gas discharged from the inflator. The airbag includes a pair of left and right side chambers that deploy from the side parts of the seatback forward and an upper chamber that is provided continuously with the side chambers and deploys above the head of the occupant. The airbag, from a state of being spread out before stowing, is rolled or folded and compressed in a long rod shape in a direction intersecting a longitudinal direction. The location corresponding to the upper chamber of the long rod-shaped airbag is stowed in a stowing part at the rear surface of the headrest at the upper part of the seatback.

Airbag device and vehicle seat

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.

A vehicle seat includes a seat back, an inflator, and a side airbag. The side airbag includes a head chamber housed along an upper frame of the seat back and configured to inflate and deploy between a shoulder belt and a head in response to supply of gas from the inflator in an event of side collision. The head chamber is housed while being folded in a seat up-and-down direction to reduce a vertical width and then rolled from a front end in a seat fore-and-aft direction.

Vehicle seat and method for folding side airbag

An airbag device installed in a vehicle seat having a seat cushion forming the seat surface and a seatback forming the backrest, and an inflator that generates expansion gas and an airbag that is deployed by the expansion gas released from said inflator. The airbag includes a pair of left and right side chambers that deploy forward from the side of the seatback and primarily protect the occupant's waist to shoulders, and an upper chamber that is continuous with the side chambers, deploys forward above the side chambers, and mainly protects the occupant's neck and head. On the left and right sides of the seatback, the location on the side where the seatbelt crosses near the shoulder is the first side, and the side opposite to said first side is the second side. A recess is formed on the first side of the airbag where the seatbelt fits.

[Problem] To expand and deploy a hood-shaped airbag in a reliably sandwiched condition between the top of a shoulder of a seated occupant and a seatbelt in a normal set condition during a collision, and reduce injury to the occupant by a device other than an airbag such as a seatbelt or the like. [Resolution Means] An airbag devicecontains an airbagand inflatorintegrally covering the headand a side portion of a seated occupant. The airbagin a flat condition prior to folding has a plurality of chambersdemarcated in a longitudinal direction. The chamberhas a head protecting chamberstored in an upper portion of a backrest portionof a seatand a pair of side protecting chambersstored in opposing positions separated in a vehicle width direction on both left and right sides of the backrest portion. At the time of expansion and deployment, the side protecting chamberexpands and deploys between the seatbeltand occupant, and thus the airbagis configured such that a space S is formed between the occupantand airbagdeployed at a position where the seatbeltpasses.

An airbag apparatus equipped in a vehicle seat having a seat cushion that forms a seating surface and a seat back that forms a backrest includes: an inflator that generates inflation gas; and an airbag housed within at least the seat back and deployed by inflation gas released from the inflator. The airbag includes a pair of left and right side chambers that deploy towards the front from a side portion of the seat back and an upper chamber that deploys above the head of a passenger. The airbag is rolled in a direction that intersects the longitudinal direction from a flat unfolded state prior to being housed or folded to be compressed into a long bar shape. A folded portion is formed by folding at least a location corresponding to the upper chamber of the long bar shaped airbag to house the folded portion above the seat back.

Airbag apparatus

Provided is a knock type writing instrument provided with a simple mechanism allowing a stable fretting operation or the like. A knock type writing instrumentis provided with: a shaft cylinder; a refillarranged inside the shaft cylinder; a springbiasing the refillbackward; an operation partpressed forward against a biasing force of the springin a knocking operation; and a main rotor, and is switchable between a writing state and a non-writing state with the knocking operation. The knock type writing instrumentis further provided with: a knock locking membermovable forward and backward inside the shaft cylinderdue to gravity; and a locking partprovided on a side of the shaft cylinderand capable of being locked with the knock locking member. When a front end of the shaft cylinderis directed upward, the knock locking membermoves backward to be locked with the locking partto prevent forward movement of the operation part

Knock type writing instrument

A curtain airbag capable of applying tension in a vertical direction to improve occupant ejection mitigation performance. The curtain airbag is housed in an upper portion of a side surface inside a vehicle cabin and deployed along the side surface. The curtain airbag includes: a main chamber having a protection area for the occupant, and receiving an inflation gas and being inflated along a side window of a vehicle; a first chamber that overlaps an upper edge of the side window of the vehicle, the first chamber extends by being deployed toward an upper side of the main chamber along the upper portion of the side surface inside the vehicle cabin. The main chamber includes a second chamber positioned in a below portion of the first chamber to overlap the vehicle beltline upon deployment.
