  • Publication number: 20240123884
    Abstract: A function-adapted three-dimensional foam structure (2) for a vehicle seat (4) has first foam structure planes (6) to ensure a constant compressive strength of the foam structure (2) in two spatial directions x, y, second foam structure planes (8) to ensure a length variance of the foam structure (2) in a spatial direction z, that is perpendicular to the spatial directions x and y. The first foam structure planes (6) and the second foam structure planes (8) are formed and distributed within the foam structure (2) such that the compressive strength of the foam structure (2) is constant in the spatial directions x, y independent of the length-wise expansion of the foam structure (2) in the spatial direction z.

  • Patent number: 11845369
    Abstract: An upholstery unit (28) for a seat of a motor vehicle has bar-form upholstery elements (30) that can be displaced relative to one another and provide a person with cushioned support. A flexible connecting layer (32) connects the upholstery elements (30) to one another and can be folded into an interspace (34) between adjacent upholstery elements (30). The upholstery element (30) has at least one pocket (36), and at least one pressure-point actuator (38) is inserted in the pocket (36) of the upholstery element (30) to apply a massage pressure to the person through a material of the upholstery element (30). The pressure-point actuators (38) in the accommodating pockets (36) of the upholstery elements (30) can be displaced relative to one another. Thus, a massage function of the upholstery unit (28) is adapted optimally to people of different heights, and provides comfortable seating in a motor vehicle.

  • Publication number: 20230350562
    Abstract: An operating interface (10) is in an interior of a vehicle and has a surface (11) that is visible in the interior. The operating interface (10) has an operating element (14) that can be shifted relative to the surface (11) between resting and operating positions. The operating element (14) has a display (17) that is inactive in the resting position and does not indicate a functional assignment of the operating element (14). However, the display (17) is active in the operating position and indicates a functional assignment of the operating element (14). The operating element (14) has a first orientation to the surface body (11) when in the operating position and has a second orientation to the surface body (11) when in the resting position. A gap (19) is formed between the operating element (14) and the surface body (11) and surrounds the operating element (14).
