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.

In a vehicle seat, a side frame of a seat back frame has a front wall that is formed so as to be bent inward continuously from a front edge of a plate-shaped portion and forms a curved region extending vertically from around the rotating shaft and reaching an upper frame, and a rear wall that is formed so as to be bent inward continuously from a rear edge of the plate-shaped portion and forms a curved region extending vertically from around the rotating shaft and reaching the upper frame, and an inner edge of the front wall has a projecting piece that spreads to the inside from a virtual outline corresponding to a shape of the upper frame and is superimposed on the front wall of the upper frame from the rear. This provides a vehicle seat that can contribute to improvement of the work efficiency when assembling a seat back frame.

In a vehicle seat, a back pad outer skin covering a surface of a back pad includes a first portion covering a surface of one part, including a side face, of a bolster pad part, and second portions covering a surface of another part that is different from the one part of the bolster pad part. A bound part is formed by binding to each other mutually adjacent end parts of the first portion and the second portions and extremity parts of expansive force transmission webbings having base portions fixed to a frame, the bound part being capable of breaking when an airbag is made to expand. A non-stretchable cloth member is disposed on a reverse side of specific outer skin portions, covering a front face of the bolster pad part, of the second portions.

In a vehicle seat having an airbag module placed in the seatback thereof, the load that may be applied to the back side of the seatback is prevented from being applied to the airbag module. The vehicle seat (1, 300, 400) comprise a seatback frame (19) including a pair of side members (26, 301) extending vertically along either side thereof and providing a structural framework of a seatback, a plate member (20, 402) positioned behind the seatback frame and including an extension (32, 410) extending in an outboard direction from the side member located on an outboard side of the seatback frame, a mounting member connected to the outboard side member, and an airbag module (23) positioned on a front side of the extension and connected to the outboard side member via the mounting member, a clearance (S) being defined between the airbag module and the extension.

A vehicle seat includes a seat cushion including a cover, a frame and a pad, a plurality of parts of the cover being restrained to the frame and the pad; a cushion airbag device mounted in a front portion in the seat cushion and configured to inflate and deploy an airbag at a time of a frontal collision of a vehicle; and a restraint release part provided in a part of the cover positioned at at least one side in a seat front-rear direction with respect to the cushion airbag device among the plurality of parts of the cover. The restraint release part is configured to release the restraint of the part of the cover with an inflation pressure of the airbag.

A vehicle seat includes a first webbing provided in a side portion of a seat back, and a second webbing provided in the side portion of the seat back so as to overlap the first webbing from outside. The first webbing and the second webbing form a bag portion that opens downward, which houses a side airbag device. The bag portion includes a webbing seam portion in which edge portions of the first webbing and the second webbing are sewn together. In a skin seam portion in which skins of a seat back skin constituting skin of the seat back are sewn together, the webbing seam portion is sewn together with the skins, in a state in which the first webbing overlaps one of the skins and the second webbing overlaps the other of the skins.

In a vehicle seat having an airbag module placed in the seatback thereof, the load that may be applied to the back side of the seatback is prevented from being applied to the airbag module. The vehicle seat (1, 300, 400) comprise a seatback frame (19) including a pair of side members (26, 301) extending vertically along either side thereof and providing a structural framework of a seatback, a plate member (20, 402) positioned behind the seatback frame and including an extension (32, 410) extending in an outboard direction from the side member located on an outboard side of the seatback frame, a mounting member connected to the outboard side member, and an airbag module (23) positioned on a front side of the extension and connected to the outboard side member via the mounting member, a clearance (S) being defined between the airbag module and the extension.

The main cushion (3) of an automobile seat (e.g. the seat pan cushion, or a backrest cushion) is provided with a shield (2). The shield surrounds at least part of the lateral sides of the main cushion and is formed of a less compressible (i.e. harder) foam than the main cushion, such that when the seat is upholstered, creases in the upholstery are reduced/prevented and gapping is avoided.

PROBLEM

To provide an airbag device capable of efficiently retaining an airbag cushion in stowed form.

RESOLUTION MEANS

An airbag device 100 is provided with a bag-shaped airbag cushion 112 in a prescribed rolled or folded stowed form, and a cover member 114 for covering an outer periphery of the airbag cushion 112 in stowed form formed of a ductile fabric material containing a plurality of polymer fibers. The cover member 114 has a hard portion 124 in a state in which at least a portion of the plurality of polymer fibers are melted together, and a soft portion 126 that bends more readily than the hard portion 124 in which the percentage of the plurality of polymer fibers that are melted is at least lower than that of the hard portion 124. The airbag device 100 is characterized by a state in which the cover member 114 is bent along the soft portion 126, covering at least a portion of the outer periphery of the airbag cushion 112 in stowed form.

[Problem] To provide a side airbag apparatus capable of quickly and properly restraining a passenger in the initial stage of deploying an airbag, along with a vehicle seat including this side airbag apparatus. [Resolution means] The airbag includes: a first chamber which is deployed towards the front of the side support part of the seat; a second chamber which starts being deployed inside the first chamber in the vehicle width direction prior to this first chamber; and a gas guide which is arranged in the first chamber so as to introduce the expansion gas (emitted from the inflator) into the second chamber. An internal vent hole, through which the expansion gas introduced by the gas guide flows into the second chamber, is formed at the boundary part between the first chamber and the second chamber. The second chamber includes: an upper region and a lower region; and an intermediate region disposed between the upper region and the lower region. In addition, at least one of the upper region or the lower region is configured to be deployed so as to protrude more to the front of the vehicle than the intermediate region.
