  • Patent number: 11192480
    Abstract: The invention relates to an upholstered part of a vehicle seat (100), at least including a foam part (12-2) which, in a foaming process, forms a permanent connection to a prefabricated shaped nonwoven (12-1), wherein the prefabricated shaped nonwoven (12-1) forms a supporting structure for the foam part (12-2). It is provided that the prefabricated shaped nonwoven (12-1?) has at least one locally situated open cavity (12-11?) which at least in sections is filled with foam, so that the foam part (12-2?) has a foam-embedded supporting and reinforcing structure at least in one section (11B?) of the cavity (12-11?).

  • Patent number: 10882423
    Abstract: A hybrid support structure for a backrest part of a vehicle seat or a back bench seat, which is formed from a metal structure and a plastic structure, the metal structure including at least one connecting profile disposed between two side rail profiles of the hybrid support structure. It is provided that the connecting profile, together with a central rib of a web structure designed as a plastic structure follows a load path-optimized main load line, which runs between two connecting points of the connecting profile on the side rail profiles, taking into account a force acting upon the hybrid support structure in at least one assumed load case.

  • Patent number: 10661683
    Abstract: A seat adjustment mechanism of a seat for facilitating entry and exit of a person into/out of an interior of a motor vehicle, wherein a backrest part is forcibly coupled to a seat part via a rocker arm such that an adjusting movement of the backrest part is transmitted to the seat part. The backrest part and the seat part of the seat are moved from a starting position to an intermediate position by a first predetermined horizontal length by means of a sliding device which is connected to an upper rail of a seat rail, wherein the backrest part is rigidly connected to a backrest release unit of the backrest part via a coupling element, which is pivotable about a first coupling element pivot axis with respect to the sliding device.

  • Patent number: 10207611
    Abstract: A method for targeted influencing of the deformation behavior of a wall-like structure, in particular a rear wall structure of a vehicle seat, which structure is heated in at least one region at least section by section by means of a laser light source. According to the invention at least one region which influences a strength and/or a tension of the wall-like structure is selectively chosen and is lasered for increasing the strength of the wall-like structure and/or for reducing tensions within the wall-like structure. The wall-like structure is characterized in that in a selectively chosen region the structure has at least one laser-welded seam which is generated by a laser light source of a laser device, increases the strength of the wall-like structure and/or reduces tensions in the wall-like structure.

  • Patent number: 9815391
    Abstract: A vehicle seat with a backrest-side and/or a seat part-side base structure which comprises at least one movable sidepiece structure. At least the sidepiece structure of the base structure is made of at least one framework structure. The at least one sidepiece framework structure has flexurally elastic flanks and deflectable transverse braces which lie between the flanks and which are arranged on the flanks via elastic connecting element, whereby a force pulse that acts on the transverse braces of the at least one sidepiece framework structure from one direction via a flexurally elastic flank causes a compensating autoreactive deformation of the at least one sidepiece framework structure in the opposite direction at another point.

  • Patent number: 8388057
    Abstract: An air-conditioned seat includes a seat area and a backrest, the seat area and/or the backrest being cushioned with foam. For climate-control, a ventilator, in particular a radial ventilator, is provided, which is in operative connection with an air distribution device in the foam of the seat area and/or the backrest, the air distribution device including an air distribution structure on the side (e.g., a B side) facing away from the seated person, as well as air-conducting channels toward the side (e.g., an A side) facing the seated person. The ventilator is to be disposed in the foam itself, on the B side. The air is transported to the A side via the air distribution structure in the form of air trenches introduced into the foam on the B side, and via the air-conducting channels.
