A method produces an element (3), in particular a vehicle seat, having a seamless cover (2). The seamless cover (2) is optionally provided with a lamination (1). A molding (1.2) is applied and fastened to a surface side (1.1) of the lamination (1) facing away from the cover (2) or to a surface side (2.2) of the cover (2) that is not visible. The fastened molding (1.2) is connected to the cover (2) by bonding.

A method of forming a seat cover may include providing a high frequency welding device, locating a seat cover in the high frequency welding device, and energizing the high frequency welding device to either join two or more pieces of the seat cover together or to impart a shape to form a contoured seat cover.

A module support arrangement for attachment to the seat structure of a motor vehicle seat and for fixing pneumatic components or non-pneumatic components has a module support with a front side and a rear side opposite the front side. Optionally, the module support arrangement has at least one further component, wherein air ducts and/or air duct sections are integrated in the module support and/or in the at least one further component. At least one pressure accumulator that is in fluidic communication with at least one of the air ducts or air duct sections is integrated on or in the module support and/or on or in the further component.

A method of forming a seat cover may include providing a high frequency welding device, locating a seat cover in the high frequency welding device, and energizing the high frequency welding device to either join two or more pieces of the seat cover together or to impart a shape to form a contoured seat cover.

A seat cover secured to a seat structure formed of a mesh body of polymer fibers that are welded together, a method of securing the seat cover having a seam to a novel mesh body seat structure, and fixture used in the method. A mesh pad of welded polymer fibers is covered with the cover including tie down strips is selected. The tie down strips are moved into predetermined locations within the mesh pad, and the mesh pad is heated in the predetermined locations to melt a portion of the polymer fibers onto the tie down strips to hold the tie down strips in the predetermined locations.

Seat assemblies and subassemblies to attach and retain components is provided. The subassembly may include a trim cover with a cushion layer, and various fasteners or retainers. The fasteners may include a tie down strip. The retainers may include a connector that is translated through the seat cushion layer. The retainers may also include an envelope to encircle the cushion layer.

An assembly includes a trim cover assembly and a comfort layer. A retention fastener includes a stem and a crossbar, and the stem is joined to one of the trim layer and the comfort layer at a joining point. The other of the trim layer and the comfort layer includes an opening, and the retention fastener received through the opening with the crossbar opposite the opening from the joining point.
