    • The present invention relates to a process for the production of a polyurethane foam backed instrument panel. This process comprises slicing a free-rise bun of polyurethane foam to form a skived polyurethane foam, bonding the skived foam to a skin material to form a laminate, optionally, rolling the foam/skin laminate, thermoforming the foam/skin laminate into an instrument panel skin, positioning the instrument panel skin into the cavity of a mold, positioning a retainer into the core of the mold, adhering the retainer to the laminate by placing an adhesive film onto the retainer, closing the mold to apply heat and pressure, and removing the resultant instrument panel from the mold. Suitable polyurethane foams for the present invention may be flexible foams or semi-rigid foams. This invention also relates to the polyurethane foam backed instrument panels produced by this process.

    • A protective foam layer is provided. The protective layer has a foam substrate that is at least partially enclosed by a formed skin adjacent the outer surface of the foam substrate. The formed skin is substantially non-porous. The combination of the foam substrate with the formed skin results in a protective layer that is effective to absorb and/or dissipate impact force for both high- and low-speed impacts that can be experienced during a sporting event such as cycling. The formed skin can also be provided with a plurality of protective zones having vent holes through the formed skin to regulate the degree of energy absorption in the respective zones. In this manner, a single continuous protective foam layer can be provided having multiple protective zones having distinct energy absorption characteristics instead of providing discrete protective layers that must be joined or meet at a seam. According to the invention, by providing such a continuous protective layer with no such seams, a known failure mode in protective equipment is eliminated.
    • 提供保护泡沫层。 保护层具有至少部分地由邻近泡沫基材的外表面的成形皮肤包围的泡沫基材。 形成的皮肤基本上是无孔的。 泡沫衬底与形成的皮肤的组合产生保护层,其有效地吸收和/或消散在诸如循环的运动事件期间可能经历的高速和低速冲击的冲击力。 形成的皮肤还可以设置有多个保护区,其具有通过形成的皮肤的通气孔,以调节各个区域中的能量吸收程度。 以这种方式,可以提供具有多个具有不同能量吸收特性的保护区的单个连续保护泡沫层,而不是提供必须在接缝处接合或相接的离散保护层。 根据本发明,通过提供没有这种接缝的这种连续保护层,消除了防护设备中的已知故障模式。
