  • Patent number: 9199686
    Abstract: The invention concerns an undercarriage (35) for a vehicle comprising a chassis, two front steering wheels (36D, 36G) and at least one rear drive wheel. The undercarriage comprises, combined with each wheel, a suspension system (39) suspending the wheel from said chassis, said system (39) comprising an upper suspension arm (40), a lower suspension arm (41) and a lateral arm (42), said arms being linked together by articulated means (43, 44, 45, 46) such that a lateral tilting of the undercarriage results in an equivalent tilting of the two front wheels, which remain parallel to each other. According to a feature of the invention, the undercarriage comprises a damper (50), integral with each front wheel, to at least partially cancel the oscillation frequencies of said front wheel.

  • Patent number: 6520491
    Abstract: An apparatus for attenuating shock loads includes a flexible, non-rigid outer impervious envelope. The envelope is formed from a high strain resistance material. An inner, pervious baffle extends across the envelope between the first and second sides. The inner baffle is also a flexible, non-rigid material of high strain resistance. The envelope is inflated with gas at a superatmospheric pressure. An impact on one side of the structure will compress that side, increasing the pressure of the gas between that side and the baffle. The gas will then flow through the pervious baffle to the other side, dissipating energy, spreading the load over the second side of the envelope and causing a time delay in the build-up of pressure on the second side. In preferred embodiments of the invention, there are plural, parallel baffles in the envelope to provide a multi-stage energy dissipation.

  • Patent number: 5409200
    Abstract: A thin sheet of metal is patterned, folded, and joined to produce an array of compression springs, each of which exhibits constant force characteristics over a useful range of deflections to allow the array to apply nearly constant specified forces to closely spaced items which may be of varying size or height. As the springs are loaded from a relaxed state, the rate of force increase per unit of increased deflection is initially high, tapering off to nearly zero force increase with subsequent increases in deflection. This region of minimal force increase per unit of increased deflection (i.e. a "near constant force" band) extends over a useful range of deflections. The springs are self guiding and balanced, producing no lateral force on a perpendicularly applied load.

  • Patent number: 5184809
    Abstract: A spring assembly has a plurality of rows of springs interconnected in chain-like fashion, each spring including upper and lower runs and an intermediate run interconnecting the upper and lower runs. The upper and lower runs each include a coil on one end and a hook on the opposite end hooked about a coil of an adjacent spring. A plurality of runner wires extend transversely of the upper runs where they are connected thereto by a plurality of helical wires respectively received about the upper runs. The upper runs are in planes above the coils of the upper runs providing recesses above the coils receiving the helical wires.

  • Patent number: 5165125
    Abstract: An improved spring is provided which may be used in cushions, mattresses, or box springs which includes a limiting internal member. This limiting member assist in limiting the longitudinal deflection of the springs. Also provided are snapped-fitting connections between the spring and a grid for use within a box spring. Also provided is a "floating" portion of a peripheral border wire, particularly suitable for use in a pair of box springs beneath a king-size mattress unit. Also provided is a corner guard which provided support for upholstered fabric on a box spring. Finally, an improved borderwireless mattress using a peripheral band is provided, which allows the mattress to bend more easily, without disadvantageous setting of its border wires.

  • Patent number: 4895352
    Abstract: An improved array of spring units. In a preferred embodiment, the spring units are composed of polyurethane which are blow molded such that a string of bellows-like springs are provided, with the axial ends of each spring being free for axial compression, while the sides of the springs are left attached to each other during the blow molding process. In another embodiment, the blow molded springs each include a vent hole which affects the dynamic cushioning properties of the springs. In another embodiment, extruded tubes of particular configurations are slotted at spaced-apart intervals such that independent spring units are provided, with the axial ends of each spring being free for axial compression. The array of spring units does not require a fabric covering as do strings of pocketed coils, but may be as easily handled, and may be connected in side-to-side abutting relationship to provide a mattress, cushion, or box spring inner construction.

  • Patent number: 4685658
    Abstract: A resilient support for receiving a force acting thereon along a certain direction, and wherein the force is opposed by a bearing counterforce acting at least partly along a direction opposite to said certain direction, and which includes a plurality of bar elements, at least two bar elements confronting one another, each of the two confronting bar elements having end regions, and forming a rod pair, a linking bar joining the confronting bar elements at a first set of connecting locations spaced at a distance from any end region of any of the confronting bar elements, two other bar elements, each connecting the end regions off the two confronting bar elements at a second set of connecting locations so as to form a closed structure therewith, the other bar elements forming a bar pair, at least two of the means being resilient in at least one of flexion and torsion, one force acting on a location of at least one of the other bar elements, the other force acting on the linking bar, at least one of the forces act
