Described are lightweight headrests with a perimeter frame 200 with an open central region. The open central region is spanned by a suspension membrane 100 held in tension. The suspension membrane provides support and cushioning functions to a passenger head without the need for internal structures or compression cushions. The perimeter frame of the headrest may have additional cross members spanning the rear portion of the headrest. These cross members may provide additional structure or locate attachment points for the headrest onto the seat.

A vehicle seat includes a seatback. The seatback includes a main frame and a sub-frame suspended from the main frame. The sub-frame is configured to swivel with respect to the main frame. The sub-frame includes a first lateral member, a second lateral member separated from the first lateral member by a distance, and a reinforcement member coupling the first lateral member with the second lateral member.

A seatback of a vehicle seat includes a seatback frame and a backrest attached to the seatback frame. The backrest includes a first supporting area configured to receive a load of a shoulder of the occupant, and a second supporting area configured to receive a load of a spine area of the occupant. Support stiffness in the first supporting area for a vertical load is lower than that in the second supporting area. Support stiffness in the second supporting area for a shearing load is higher than that in the first supporting area.

Provided is a cushion pad, in which a seating body portion of a seating portion has a bottomless or bottomed first hole arranged at a position at which the first hole overlaps a pair of ischial bones of a seated person in a horizontal projection plane and three or more bottomless or bottomed second holes with areas that are smaller than an area of the first hole in a horizontal projection plane, a center point O51 of the first hole is on or inside a triangle TR obtained by connecting center points of any three second holes from among the three or more second holes in the horizontal projection plane and in the seating portion, the inside of the first hole is a void space, or a soft material portion is arranged inside the first hole.

A vehicle seat having at least one seat shell, the seat shell having a frame with two spaced-apart frame units and a shell surface arrangement extending from one of the frame units to the other frame unit. The shell surface arrangement has a net-like structure having a first fiber-reinforced plastic, and the seat shell has at least one holding element connected to a corresponding receiving element for fastening the seat shell.

A seat suspension with suspension strands which comprises a fan grille of plastic provided with anchoring points overmolded on at least some of the suspension strands.

A method for making a seat includes the step of overmolding a carrier onto a fabric seat surface. The fabric surface is formed from a woven fabric material having heating element fibers. The heating element fibers are placed in contact with a conductor. The carrier and the conductor are then positioned into a frame.

Described are passenger seat bottom assemblies that include a layered seat bottom assembly formed of a first face sheet, a lightweight core layer, and a second face sheet bonded together, preferably in a flat or substantially flat arrangement. The core layer can be a honeycomb structure, e.g. a metal or aluminum honeycomb, or a foam, that confers a high strength and stiffness to the seat bottom assembly with minimal forming and minimal weight.

The example of the vehicular interior trim according to the present application is multilayer structure including at least a base material and a skin layer. The multilayer structure is configured to satisfy the relationships in the following expressions (1) and (2), where RSm (mm) is the average surface roughness of the base material in the horizontal direction, E1_80is the Young’s modulus of the base material at 80° C., d1 (mm) is the thickness of the base material, E2_80 (GPa) is the Young’s modulus of the skin layer at 80° C., and d2 (mm) is the thickness of the skin layer. Expression (1): Expression (2):

[00001]$0.15\text{<}\text{RSm}/\left(\text{E2\_80}\times \text{d2}\right)$

[00002]$\text{RSm}/\surd \left(〚\left(\text{E1\_80}\times \text{d1}\right)〛\text{^2+}〚\left(\text{E2\_80}\times \text{d2}\right)〛\text{^2}\right)\text{<135}$

A seat adjuster may include a support member and a fluid bladder. The support member may have a first end and a second end. The first end and the second end may be connectable to a seat frame such that the support member is disposed at least partially below a suspension portion of said seat frame. The fluid bladder may be disposed at least partially between the support member and said suspension portion. The fluid bladder may be configured to support said suspension portion. A change or adjustment of a volume of the fluid bladder may change or adjust the support provided to said suspension portion.
