A vehicle seat according to the present disclosure includes a pad including a foam, and a volume adjustment mechanism that allows adjustment of a volume of the foam. An adjustment method for a pad vibration characteristic according to the present disclosure adjusts a volume of a foam included in a pad to adjust a vibration characteristic of the pad.

A seat assembly includes a seatback having a cushioned component pivotally coupled to the seatback and operable between deployed and retracted positions. The cushioned component includes an interior cavity. A rack assembly is positioned within the interior cavity and includes a forward-most rack with a first receiving area. The rack assembly further includes a rearward-most rack having a second receiving area. A first cartridge assembly is removeably received in the first receiving area of the rack assembly. A second cartridge assembly is removeably received in the second receiving area of the rack assembly. The rack assembly may also include one or more intermediate rack assemblies positioned between the forward-most and rearward-most rack assemblies for supporting other intermediate cartridge assemblies. Each cartridge assembly includes a different density profile for providing variated comfort settings to the seatback of the seat assembly.

Disclosed are a hot melt tape for hook-and-loop fasteners without sewing which may be adhered at a low temperature and complete hardening of an adhesive resin in a short time and a method for manufacturing a seat padding material for vehicles using the same. The method includes preparing the padding material and a hook-and-loop fabric, preparing a hot melt tape having a hot melt resin layer by coating a surface of a release paper with a reactive hot melt resin having a melting point of 40-80° C. before reacting, adhering the hot melt tape to a surface of the padding material by applying heat of a temperature of 30-70° C. and pressure thereto, removing the release paper, adhering the hook-and-loop fabric to the exposed hot melt resin layer, and hardening the hot melt resin layer by cooling the padding material and the hook-and-loop fabric to a temperature of 0-20° C.

A vehicle seating assembly includes a frame, a front closeout panel supported on the frame and an articulating flexmat assembly operably coupled with at least one of the front closeout panel and the frame. The articulating flexmat assembly includes an upper flexmat extending from a first side of the frame to a second side of the frame. The upper flexmat includes an upper cable coupled with the upper flexmat and an upper cable regulating motor operably coupled with the upper cable. The articulating flexmat assembly also includes a lower flexmat extending from the first side of the frame to the second side of the frame. The lower flexmat includes a lower cable coupled with the lower flexmat and a lower cable regulating motor operably coupled with the lower cable.

A support device has a main support surface for a person's body, including an auxiliary device influencing the main support surface shape. The auxiliary device includes: a group of supports supporting the main support surface, positioned on the side of the main support surface facing away from the body-supporting side, the supports each including a sub-support surface; an adjuster for each sub-support surface influencing the height of each sub-support surface. The device also includes a monitor for each sub-support surface monitoring the height of the respective sub-support surface; and a programmable control unit controlling the adjuster. The supports include an elastically bendable plate connected to the adjuster. The bending plate is connected to the sub-support surface to influence its height depending on the extent of bending imposed by the adjuster. The adjuster includes an electromotor on the concave side of the bending plate.

A mesh type seat for a vehicle includes a mesh mounted for supporting the upper body and the lower body of a passenger on a seat frame. An elastic member and a damping member are installed on the mesh type seat and are capable of adjusting the tension of the mesh to the side of the seat frame, thereby providing a comfortable seating feeling to the passenger by adjusting the tension of the mesh while maximizing ventilation performance.

A seat for a vehicle includes a seat back frame, a first elastic member, and a second elastic member. The seat back frame includes a main frame and a sub-frame. The first elastic member and the second elastic member are configured to support the sub-frame such that the sub-frame is rotatable in a width direction of the seat and are mounted between the main frame and upper end portions of the sub-frame on both sides in the width direction of the seat. Each of the first elastic member and the second elastic member has a limit of elongation and has a characteristic in which a load that is applied to the sub-frame in a rear direction of the seat acts as tension to generate a reaction force due to the limit of elongation and does not generate the reaction force in the width direction of the seat.

A vehicle seat cushion carrier assembly (bottom and back) via which a cushion carrier structure, cushion foam, and upholstery are more easily assembled and installed in a vehicle, optionally as a modular unit. The cushion carrier structure can be multi-piece and incorporate any desired trim units. Strap fasteners are used to secure the upholstery to the cushion carrier structure and cushion foam, creating the desired creating seams, creases, and indentations. Clip fasteners are used to secure the upholstery to the cushion carrier structure around the cushion foam, especially with respect to the seat back. This allows much of the upholstering to be done outside the vehicle, optionally in a modular manner. Finally, these modular features and functionalities allow the cushion carrier assemblies (bottom and back) to be quickly and easily secured to the underlying seat pan and/or seat frame using simple screws, hooks, and clip fasteners.
