A vehicle seat structure for a vehicle seat may have a structural component having an inertia belt reel. The inertia belt reel may be arranged in a cavity of the structural component, and the structural component may be connected to at least one further component of the vehicle seat structure. A method for assembling such a vehicle seat structure may include providing a structural component having an inertia belt reel and at least one further component of the vehicle seat structure that are displaced and/or rotated relative to one another such that the structural component and the at least one further component of the vehicle seat structure take up an end position with respect to one another. In a further step, the structural component and the at least one further component of the vehicle seat structure are connected to one another in a form-fitting and/or integrally bonded and/or force-fitting manner.

A method of welding a support on a slide profile, which comprises: a) providing a support having a wall with an inner face, and providing a profile having a wall with an outer face, b) positioning the interface support with the inner face of its wall against the outer face of the wall of the profile, c) creating a welding joint between the wall of the support and the wall of the profile by moving a laser beam relative to the wall of the profile, while keeping the laser beam in a position such that it successively passes through, from an emitting source: the wall of the profile, then the wall of the support, while remaining within the material of the wall of the support.

A seat assembly and a method of manufacture. The seat assembly may include a seat bottom frame that has a perimeter tube assembly that may define an opening and a cross tube assembly that may extend across the opening. The perimeter tube assembly, the cross tube assembly, or both may have a telescoping tube joint.

A vehicle seat with a speaker-equipped headrest is provided, which is of a relatively simple structure to enable the speaker-equipped headrest to be easily mounted to/dismounted from a seat body after vehicle installation, and also provide increased versatility for installation in vehicles of various vehicle size classes. The vehicle seat with the speaker-equipped headrest includes: a male coupler that is connected to a speaker harness and fitted to a distal end of a headrest stay; and a female coupler that is connected to a main harness on a seat body side, and fitted to a headrest guide bracket supporting a headrest guide. Insertion of the headrest stay into the headrest guide allows the speaker-equipped headrest to be mounted to the seat body, and allows the male coupler and the female coupler to be fitted together to provide a connection between the speaker harness and the main harness.

A vehicle seat is provided with a frame, a cushion pad which is disposed on the frame, a trim cover which covers the cushion pad, and a fastener provided to the surface of the cushion pad, which is installed on the frame. The fastener has a frame affixation section which is affixed to the frame, and a cover engagement section with which an end of the trim cover is engaged, and the fastener is joined to the cushion pad.

A seatback carrier module includes first and second side portions spaced-apart from one another and interconnected by an upper portion. A cradle portion is disposed along the first and second side portions and the upper portion of the seatback carrier module. The cradle portion includes inner and outer edges with a rearwardly extending body portion. A mounting portion is disposed along a portion of the inner edge of the cradle portion. The mounting portion includes inner and outer edges with a body portion disposed therebetween. The mounting portion further includes a rearwardly extending sidewall disposed along the inner edge of the mounting portion. An airbag assembly is received within the cradle portion and has an inverted U-shaped configuration to substantially surround the outer perimeter of the seatback frame. The airbag assembly is an elongate member defining an overhead airbag assembly.

A seatback assembly includes a front carrier module having a mounting portion with an inverted U-shaped outer perimeter edge. A plurality of doors includes individual doors that are hingedly coupled to the outer perimeter edge of the front carrier module. Each door of the plurality of doors is operable between open and closed positions. An airbag carrier module includes an inverted U-shaped raceway with an open front portion. The airbag carrier module is operably coupled to the front carrier module, such that the doors of the front carrier module selectively open and close the open front portion of the raceway of the airbag carrier module.

A vehicle seat assembly is provided with a seatback frame adapted to be mounted to a vehicle interior. The seatback frame has a front region facing a forward direction, and a rear region. A first bracket is mounted to the front region of the seatback frame. A second bracket is mounted to the first bracket and the rear region of the seatback frame. At least one head restraint post is mounted to the first bracket or the second bracket and spaced apart from the seatback frame so that upon a rear vehicle impact, the second bracket deforms as the at least one head restraint post is translated toward the seatback frame.

To reduce an amount of rear protrusion of a vehicle seat equipped with an airbag module configured to deploy rearward, in a vehicle seat (1) provided with a seat cushion (3) and a seat back (4), the seat back includes: a seat back frame (7) including a pair of left and right side frames (11) extending in a vertical direction and an upper frame (12) connecting upper ends of the side frames to each other; an airbag module (43) supported by an upper half of the seat back frame via a bracket (31); and a skin member (9) covering the seat back frame, the bracket, and the airbag module from a rear side thereof, wherein a part of the skin member corresponding to the airbag module is provided with a frangible portion (80) configured to open upon inflation of an airbag (45).

A frame side plate part of a frame member of a seat along a side surface of a backrest; and a bracket attached to the frame side plate part in a condition where an airbag cushion and an inflator are secured. The frame side plate part has a notch region where a predetermined range of a front edge is cut out The bracket has: a base part which is fitted into the notch region of the frame side plate part and to which the airbag cushion and the inflator are secured; and a reaction force plate bent from a front side of the base part and extends to one side in a vehicle width direction. Guide grooves are formed on an upper edge and lower edge of the notch region, and the base part can be inserted into the notch region from the front along the guide grooves.
