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.

To provide a vehicle seat which makes the load from the airbag more likely to be concentrated on a weakened part of a skin member, a vehicle seat provided with a seat cushion constituting a seating surface and a seat back constituting a backrest including a seat back frame forming a structural member of the seat back; an airbag module supported on a side portion of the seat back frame on a vehicle outer side; a pad member covering the airbag module; and a skin member covering a surface of the pad member, wherein the skin member is provided with a weakened part vertically extending on an edge part of the seat back on a vehicle outer side and a first low-elasticity reinforcement part extending from a vicinity of the weakened part in a direction intersecting with the weakened part.

The present disclosure discloses an automobile seat cover capable of releasing a safety air bag and a sewing technology of a seat cover. An air bag detonation edge is sewn. The air bag detonation edge is defined on the seat cover side cloth and a sewing position between the seat cover backrest cloth and the seat cover rear cloth. A braid with a width of 4 MM is sewn at the air bag detonation edge through an air bag bottom thread and an air bag upper thread. The common computer automobile is reformed, the number of needles and the needle pitch are strictly controlled by biasys computer software, the tension of the air bag bottom thread and the tension of the air bag upper thread are strictly controlled through a tension controller. The upper half part of the seat cover is integrally sewn.

Some embodiments are directed to a guide structure for use with a deployable airbag assembly of a vehicle seat, the vehicle seat having a frame extending therein. The guide structure can include an elongated plate configured to be connected to at least one of the frame and the airbag assembly such that the plate extends along an exterior thereof, the plate including: a first end configured to be connected to the at least one of the frame and the airbag assembly by a fastener; and a second end configured to be inserted through a slot in the at least one of the frame and the airbag assembly so as to be disposed within an interior thereof. The guide structure can also include a sheet connected to the plate, the sheet configured to thereby guide deployment of the airbag assembly.

A side air bag device restraining an occupant at the early stage of the deployment. A seat back has a side support part bulging in a vehicle forward direction at a side part in a vehicle width direction. A seat frame of the seat is provided inside the seat. The side air bag device has an air bag deploying to restrain an occupant and an inflator supplying inflating gas. A side frame part of the seat frame is inside the side support part, and the side air bag device is on an outer side of the side frame. The air bag has a main chamber deploying forward and to an outer side of the side support part and a sub-chamber deploying inside the side support part. The sub-chamber deploys further toward a forward side than a vehicle forward edge of the side frame, at least a front part of the side support part protrudes and deforms toward an occupant side.

A base material for a seatback side includes a body portion including a protruding portion. The protruding portion has a plate piece surface of a distal end extending from the body portion outwardly relative to an outer portion provided on an outer side in a vehicle width direction. The plate piece surface is placed side by side with a flange surface of a flange portion projecting in a peripheral portion of the body. The distal end is sandwiched by a weather strip together with the flange portion.

A vehicle seat part has a cover with a tear seam and an airbag module with an airbag and a force concentrator. The force concentrator partially surrounds the airbag. The concentrator has two end regions connected to the cover adjacent to and on opposing sides of the tear seam. One of the end regions is connected to the cover at a plurality of connecting portions spaced apart from one another.

A side airbag device includes: an inflator configured to inject gas into an airbag; a case including a mount wall for the inflator to be mounted thereto; an inflator anchoring member provided on a side of the mount wall opposite to an inflator side and attached to the inflator by a mounting member with the mount wall held between the inflator anchoring member and the inflator; an outer covering material configured to cover the case; a restriction member fixed at a position around a seam of the outer covering material and configured to restrict a direction of deployment of the airbag; and an engaging portion provided at an end portion of the restriction member and configured to engage with the case, the engaging portion being located in place at the case, to thereby be restricted in movement.

A seat back of a vehicle seat, including: a side frame provided inside a cushion member in which an accommodation portion is formed; a cover material that covers a surface of the cushion member; an airbag accommodated in a folded state in the accommodation portion; a cylindrical inflator provided in the accommodation portion; a first retaining cloth, one end portion of which is connected to a rupture portion; a second retaining cloth, one end portion of which is connected to the rupture portion; and a joining member that joins together the respective other end portions of the first retaining cloth and second retaining cloth at the accommodation portion, wherein, when viewed along an axis of the inflator, a front end portion of the side frame is disposed forward of the inflator and the joining member is disposed forward of a front end portion of the side frame.
