  • Patent number: 8435622
    Abstract: A packaging film with a main film made of a stretchable polymer film material and having a multiplicity of holes. A first condition of the main film including that a ratio of aeration percentage over final weight is greater than or equal to 14 meters per gram. A second condition of the main film is that the width of the packaging film is reducible by less than 15% between a condition before any stretching of the packaging film and a condition when the packaging film is stretched at an elongation equal to the elongation at the NDR point. A third condition of the main film is that a ratio of an absolute value of the difference of a holding force of the packaging film minus a predetermined target holding force divided by the target holding force is less than or equal to 5%.

  • Patent number: 8053055
    Abstract: A stretch film comprising a base film made of a stretchable plastic film material, a multiplicity of holes in the base film arranged in several columns along a main direction, at least one reinforcement strip made of a stretchable plastic film material. The reinforcement strip is arranged and fixed on the base film in an area between two adjacent columns of holes. The thickness of the base film is greater than or equal to the thickness of the reinforcement strip and the width (w) of the reinforcement strip is as great as possible, but is such that the reinforcement strip does not contact or overlap the holes in the adjacent columns of holes. The reinforcement strip may be fixed to the base film so as to be inseparable and indistinguishable from the base film.

  • Publication number: 20090047468
    Abstract: A packaging film comprising a main film made of a stretchable polymer film material and having a multiplicity of holes on the main film includes is four conditions. A first condition means that a ratio of aeration percentage over final weight is greater than or equal to 14 meters per gram. The aeration percentage is calculated for a predetermined length of the packaging film as the total area covered by the holes over the total area of the packaging film including the area of the holes, when the packaging film is stretched to an elongation equal to the elongation at the Natural Draw Ratio point (NDR point). The final weight is the weight of the packaging film per film meter measured in grams per meter, when the packaging film is stretched at an elongation equal to the elongation at the NDR point.

  • Patent number: 6227617
    Abstract: A lumbar support for seat backs, in particular of motor vehicle seats, has a forward-bowed support plate (1). The support plate (1) is height-adjustable, moving upward and downward on guide organs that are fixed with respect to the seat back, and is also variable in its curvature through the use of a motor-driven tension bracket that can be lengthened or shortened. The tension bracket consists of bracket regions (3a and 3b) that act on upper end region (1a) and lower end region (1b) of the support plate (1). The bracket regions have thread regions of opposite handedness pointing toward one another which are externally engaged by a common rotatable sleeve (11) with appropriately designed meshing areas. The drive motor (10) is fixed to a gear case (2) arranged behind the support plate (1). The motor (10) drives gear wheels of a gearbox whose final gear wheel (13a) stands in engagement with the sleeve (11). The sleeve has inside thread regions of opposite handedness.

  • Patent number: 6139102
    Abstract: A lumbar support for seat backs, in particular of motor vehicle seats, has a forward-bowed support plate (1) that is adjustable in its curvature. The support plate (1is mounted at one horizontal end region (1a) on laterally spaced guide elements that are parallel to one another and fixed with respect to the seat back so that it is vertically movable. The vertical guide elements consist of ribs (2) of a guide plate (3) that is fixed with respect to the seat back. The guide plate (3) has openings (4), which possess vertical guide edges (4a) that are parallel to one another. Through the guide edges (4a) pass, from the front, end-mounted brackets (1b) of the support plate (1). The brackets (1b) have necks (1c) corresponding to the spacing of the guide edges (4a), and widen again on the back of the guide plate (3).
