  • Patent number: 7399028
    Abstract: An energy-absorbing vehicle hood includes outer and inner layers defining a cavity filled with foam material. The outer layer fractures when subjected to a crush load to thereby transmit the load to the foam material where it is absorbed, and both layers are continuously and directly bonded to the foam material. A vehicle includes a vehicle hood assembly having outer and inner layers defining a cavity, with foam material filling the cavity. The outer layer fractures when subjected to a crush load to transmit the load to the foam material for uniformly absorption of the crush load. A hood panel is also provided for use with a vehicle, including an energy-absorbing polymer foam material entrapped between an outer and inner polymer membrane. The membranes have a crush strength, and the foam material is characterized by an absence of a reinforcing structure.

  • Patent number: 7141194
    Abstract: The hollow profiles with inner reinforcement are especially suited for use in automobile bodies. The aim of the invention is to ensure that an anti-corrosion medium reaches all areas and to obtain rigidity in a hollow structure without increasing the weight of the profile or enlarging its cross-section. To this end, a solid core material is coated with an activable material and an outer panel is arranged in such a way as to form a hollow space which can be filled through the foaming action of the activable material. The size of this hollow space is determined by how the spacers are determined and by how the spacers are arranged, depending on the particular application. The solid core material consists of a foamed or non-foamed metallic material or of a synthetic material reinforced with metal fibers, carbon fibers or glass fibers.

  • Patent number: 6929312
    Abstract: An HVAC duct is mounted within a pillar providing a frame element of a framing structure defining a passenger compartment of a vehicle such as a van, an SUV or a station wagon. The HVAC duct is stabilized within the pillar by a layer of structural foam or other cellular structure which is adhered to the interior surface of a wall of the pillar, for example, by heat expanded epoxy adhesive. In a method of assembling the HVAC duct and pillar, the duct is mounted on an interior wall portion of the pillar prior to enclosing the duct in the pillar by welding an exterior wall portion of the pillar to the interior wall portion of the pillar. Upon heating the pillar to bake the frame assembly after painting the frame assembly, the heat expandable epoxy expands and adheres to interior surfaces of the pillar walls. The resulting structure reduces structural intrusion into the passenger compartment by the duct and pillar assemblage, while increasing the cross-sectional area of the pillar.

  • Patent number: 6920693
    Abstract: There is disclosed a reinforced structural assembly and a method of using the assembly for sealing, baffling and/or reinforcing components of an automotive vehicle. The assembly generally includes at least a first mass of expandable material. Preferably, the first mass is movably (e.g., rotatably) connected to a second mass of material and/or another member. According to the method, the assembly is placed in a cavity of an automotive vehicle and the at least one mass is activated to expand. Preferably, upon activation, the first mass self adjusts by moving (e.g., rotating) relative to the second mass and/or the other member.

  • Patent number: 6890021
    Abstract: A modular segmented structural reinforcement system for use with closed forms or cavities defined with automotive vehicles having a plurality of modular segments designed to be secured within a defined portion of an automotive vehicle applications. An expandable or bonding material, such as an epoxy-based reinforcing foam or other sound absorption, damping, vibration reduction, or sealing material is disposed on at least a portion of the outer surface of each of the plurality of segments. Once the system is flexible fitted within the closed form or placed within a selected cavity of an automotive vehicle, the material expands and cures during an automobile assembly operation, bonding the reinforcement system to the segments. As a result, the reinforcement system provides enhanced load distribution over the vehicle frame without adding excessive weight and further serves to reduce noise and vibrational characteristics of the automotive vehicle.

  • Patent number: 6877795
    Abstract: A mechanical, active crash pulse management structure for providing modification of crash pulse, wherein the structure has a dormant (initial) state volume, but then in the event of a crash, timely expands into a much larger deployed volume for providing management of an expectant crash energy. The preferred crash energy management structure is a before expansion honeycomb celled material brick, wherein expansion of the honeycomb brick is in a plane transverse to the cellular axis of the cells thereof, and crash crush is intended to be parallel to the cellular axis. In the event of a crash, either an active or passive activation mechanism is provided for causing expansion of honeycomb celled material.

  • Patent number: 6866331
    Abstract: The present invention describes a hollow structural body such as an automotive unibody or frame rail that is reinforced with a reinforcing material such as a polyurethane foam by inserting into a portion of the structural body a bulkhead-containing insert, which, in combination with the structural body at the place of insertion, creates a containment region for the reinforcing material. Uncured reinforcing material can then be added to the containment region and cured. The present invention solves a problem in the art by providing structural reinforcement to be easily and precisely placed within the structural body to provide, for example, enhanced crash resistance or improvements in acoustical properties.
