A seat assembly for a vehicle includes a seatback having a seat frame. The seat assembly includes a panel having an end slidably supported by the seat frame. The panel is bowable outwardly from the seat frame to a deployed position. The seat assembly includes an actuator supported by the seat frame and connected to the end of the panel.

A connection bar mounting structure includes: link members, each including a first hole part in a middle part; vehicle members, each configured to rotatably support each link member at a first fixation part of each link member; side frames, each configured to rotatably support each link member at a second fixation part of each link member opposite to the first fixation part across the first hole part; and a connection bar, each end thereof fixed to the first hole part of each link member. Each link member has a first bending rigidity reduced section between the middle part and the first fixation part and a second bending rigidity reduced section between the middle part and the second fixation part, the first and second bending rigidity reduced sections having bending rigidity smaller than those of the middle part, the first fixation part, and the second fixation part.

A vehicle seat including at least one outer frame on which an outer part of a seating surface is supported, and at least one inner frame on which an inner part of the seating surface is supported and which is movable relative to the outer frame.

A vehicle seat including at least one outer frame on which an outer part of a seating surface is supported, and at least one inner frame on which an inner part of the seating surface is supported and which is movable relative to the outer frame.

Disclosed are a seat frame assembly and a method of manufacturing the same whereby adhesion of a reinforcing material attached to a seat frame is improved to secure rigidity of the seat frame and process speed is improved. According to one embodiment disclosed herein, seat frame assembly includes: a frame configured such that a portion of each of opposite sides is bent forward, and supporting an upper body of an occupant; and side members joined to the opposite sides of the frame, respectively, each of the side members including a groove formed in a surface being in close contact with the frame, wherein a portion of the frame that is surface-joined to each of the side members is provided with a protrusion inserted into the groove.

Described are modular leg assemblies for passenger seats. The modular leg assemblies can include a universal first leg member, a universal second leg member, a size specific member, and a universal seat frame tube receptor. The universal first leg member may be coupled to a first seat track fitting. The universal second leg member may be coupled to a second seat track fitting. The size specific member may be coupled to the universal first leg member and to the universal second leg member. At least one of the universal second leg member or the universal seat frame tube receptor can include a set of attachment points for coupling the universal seat frame tube receptor to the universal second leg member.

The present disclosure relates to a seat element, in particular, a headrest for a vehicle seat, the seat element comprising at least one support bar made of metal, a first layer provided at an exterior surface of the support bar, and a cushion made of an upholstery material. Hereby, the first layer is formed by blowing on first fibers made of plastics which are thermally welded directly or indirectly to the exterior surface.

At least part of the first fibers extends away from the exterior surface and/or the first layer towards the outside into the upholstery material and is thermally cross-linked with the upholstery material, in particular, blown-on further fibers.

A frame structure (5) for a vehicle seat backrest (3), said frame structure (5) comprising a centre frame (18) and a side frame (14), said centre frame (18) and said side frame (14) extending in a longitudinal (x), transversal (y) and vertical (z) direction, respectively, said longitudinal (x), transversal (y) and vertical (z) directions being perpendicular to each other and corresponding to a longitudinal, transversal and vertical direction, respectively, of a vehicle. Said frame structure (5) further comprises a lower connection (7) which is adapted to interconnect said centre frame (18) and said side frame (14) and which is located at or adjacent to a lower end of said frame structure (5) in said vertical direction (z).
