    • A cushion that is heated convectively using a positive temperature coefficient of resistance type resistive heating element that is provided with heat exchanging surfaces, includes a mattress pad, seat or the like with a bottom surface secured around its perimeter to an air permeable top surface, forming a plenum and containing tubular spacer material or other air flow structure therein. The plenum is connected to a power unit housing a blower, a heating module and a controller unit. The heating module includes a PTC type heating element in conduction with a base plate and a number of heat exchanger fins. Preferably the heating element is sandwiched between a pair of the base plates and the heat exchanger fins, and there is a seal between the base plates to minimize air flow from the blower from passing there between. A remote control for r.he user's convenience may be provided, and a foldable antenna attachable to the convective unit facilitates wireless communication between the remote control and controller unit. The user resting atop the cushion is able to control the blower and heating module to deliver air of a desired temperature and quantity to the cushion and through the top surface. The invention advantageously replaces the current carrying, conductive wires and insulation found inside prior art heated mattresses, enhancing safety and performance while at the same time offering a cooled or ventilated capability.
    • 使用设置有热交换表面的电阻式电阻加热元件的正温度系数对流加热的衬垫包括具有围绕其周边固定的底部表面的床垫衬垫,座位或类似物 到透气顶部表面,形成充气室并在其中容纳管状间隔材料或其他气流结构。 充气室连接到容纳鼓风机,加热模块和控制器单元的动力单元。 加热模块包括PTC型加热元件,该PTC型加热元件与基板和多个换热器翅片传导。 优选地,加热元件夹在一对基板和热交换器翅片之间,并且在基板之间存在密封以使来自鼓风机的空气流从其间流过。 用户方便的遥控器可以被提供,并且可附接到对流单元的可折叠天线便于遥控器和控制器单元之间的无线通信。 搁置在衬垫顶上的用户能够控制鼓风机和加热模块以将期望温度和量的空气输送到衬垫并穿过顶表面。 本发明有利地取代了现有技术加热床垫内存在的载流导线和绝缘层,提高了安全性和性能,同时提供了冷却或通风能力。

    • A mattress for use in institutions, such as correctional facilities, detention centers, rehabilitation centers, hospitals and the like, includes a core formed of a padding material and a translucent covering surrounding the core. The core is visible through the translucent covering, and the covering includes a translucent fabric having a rip stop pattern woven therein. One of the padding material and the translucent covering is impregnated with a color change composition. The color change composition is changeable from an initial color to an activated color. The activated color is visible through the translucent covering.
    • 用于矫治设施,拘留中心,康复中心,医院等机构的床垫包括由衬垫材料形成的芯部和围绕芯部的半透明覆盖物。 核心通过半透明的覆盖物可见,并且覆盖物包括其中编织有撕裂止挡图案的半透明织物。 浸渍材料和半透明覆盖物之一用变色组合物浸渍。 颜色变化组成可从初始颜色变为活化颜色。 激活的颜色通过半透明的覆盖物可见。

    • A mattress cover that enhances an existing mattress is comprised of a skirt and a pad formed from textile material and dimensioned to cover a non-pillow top mattress. The pad is formed from textile material and includes a compressible fill material. The pad is for being positioned over the top of the mattress and is secured to the skirt. The pad includes a trough that extends around at least part of the outer periphery of the pad. The trough has a generally planar lower face that extends generally perpendicular to the skirt and includes an outward end secured to the skirt. The trough has a generally planar upper face connected to the lower face at an inward seam and angled from the lower face at an acute angle such that the trough is generally v-shaped in cross section.
    • 增强现有床垫的床垫罩由裙部和由纺织材料形成的垫组成,并且尺寸适于覆盖非枕头顶部床垫。 衬垫由纺织材料形成并且包括可压缩的填充材料。 该垫用于定位在床垫的顶部上并且被固定到裙部。 垫包括围绕垫的外周的至少一部分延伸的槽。 槽具有大致平坦的下表面,其大致垂直于裙部延伸,并且包括固定到裙部的外端。 槽具有大致平坦的上表面,其在向内接合处连接到下表面并且从下表面以锐角成角度,使得槽的横截面通常为v形。
