  • Patent number: 10443231
    Abstract: A sealing member for use between a flashing member and a roofing material is made of a compressible material and with slits and/or weakening sections extending into the sealing member from the exterior surface towards the interior surface, each slit and/or weakening section extending from one side surface to the other side surface. In one embodiment the slits and/or weakening sections extend in parallel planes, each plane being substantially parallel to the height direction and extending at an angle of 15-75 degrees to the length direction of the sealing member, preferably an angle of 45 degrees. In use the sealing member is arranged on a flashing member and a roofing material is arranged to rest on the sealing member and compress one or more sections of the sealing member. If the sealing member includes weakening sections, at least one of these is at least partially broken when the sealing member is compressed.

    Abstract: In a spring element according to the present invention, all channels formed in the elastomer block are mutually parallel and all cavities formed in the elastomer block, too, which are intersected by said channels, are arranged like a cubic-free-centered sphere packing in reverse order. Comprising a good mechanical lateral rigidity, a spring element according to the present invention shows exceptionally good acoustic insulating and damping facilities.

  • Patent number: 4925163
    Abstract: The invention relates to a spring element (1) used for elastically supporting large loads. The spring element comprises an elastic rubber block having uniformly distributed spherical cavities (2) which are intersected by clindrical or prismatic channels (3) also formed in the rubber material. The channels (3) form groups of channels defining areas stacked on top of each other in the direction of the vector of a load to be supported, which areas neither intersect nor touch each other. These areas may be three-dimensionally-shaped areas, for example envelopes of a cone or corrugated areas, as well as mutually parallel planes oriented obliquely to the direction of the load vector. When projected onto a horizontal plane, the groups of channels (3) are either radially extending and uniformly angularly spaced if the areas are envelopes of a cone, or are mutually parallel if the areas are obliquely arranged planes. In no way, the channels (3) intersect or touch each other.

  • Patent number: 4627114
    Abstract: A shock attenuation structure having a breadth greater than its thickness and a breadthwise cross section comprising a series of layers arranged side-by-side. The series of layers comprises a first plurality of layers of shock-absorbing material having a relatively high resistance to compression and a second plurality of layers of shock-absorbing material having a lower resistance to compression, the layers of the second plurality alternating with the layers of the first plurality across the breadth of the structure and providing lateral support to the layers of the first plurality. The structure is adapted to be mounted with its breadth generally perpendicular to the direction of impact force for broadside loading of the structure during an impact, the layers in the area of impact being adapted to deform for attenuating the shock resulting from the impact.

  • Patent number: 4529248
    Abstract: A composite underbody cushioning and ventilating structure of general use and especially useful as a seat pad for the occupants of vehicles, formed of two sheet members with padding material between them, one sheet member being of woven, fibrous decorative material designed for ready passage of air therethrough and the other sheet member being a formed plastic three-dimensional preferably air impervious sheet member that serves the multi-purposes of (a) spacing the sheet members apart for passage of ventilating air between them; (b) presenting an exterior surface that ventilates by lateral air movement and thermal current air movement within local areas of the member; (c) acting as a support for a body while contacting the body in measurably less than 50% of the area of the body; and (d) presenting an exterior surface having a decorative appearance. The present invention also involves the features of the formed plastic sheet member, per se.

  • Patent number: 4139187
    Abstract: A cushion includes a core, a shell surrounding the core, and a flexible membrane interposed between the core and the shell. Both the core and shell are formed from foam material, with the foam material of the core being substantially stiffer upon initial loading than the foam material of the shell. The membrane is also formed from foam material, but is quite a bit denser than the foam material of either the core or shell. The overall effect of the membrane and the different load bearing characteristics for the two foam materials is a cushion which is quite soft to touch, but nevertheless capable of supporting heavy loading without excessive deflection. The cushion is produced by placing the core, which is cut from slab foam, into a mold cavity and then molding the shell about it.

  • Patent number: 4110881
    Abstract: Resilient articles, such as, mattresses and cushions of varying yield resistance to accommodate the weight variation of the body and/or to provide edge support are produced by tailoring tensile forces within the article. Tensile force variation may be accomplished in articles of uniform density by slotting to separate adjacent regions in at least one direction. Tailoring is accomplished by variation in slot depth and/or spacing.

  • Patent number: 4043544
    Abstract: This disclosure relates to a pad for seats, back rests, mattresses and the like comprising a pad body of plastic material with recess means therein and a covering layer overlying the pad body, strips of reinforcing material sandwiched between the pad body and the covering layer, and at least selected ones of the strips being in alignment with the recess means whereby heat is dissipated from the covering layer through the recess means and the pad is reinforced by said strips.

  • Patent number: 4027843
    Abstract: A rocker provides complex rocking motion by virtue of a volume-compressible foam section sandwiched between two substantially rigid upper and lower plate sections. The upper plate, volume-compressible foam, and lower plate sections are secured to form a single integral unit that provides complex relative motion between the upper and lower sections, which motion exhibits pitch and roll characteristics about a vertical axis through the center of gravity of the rocker when occupied.
