摘要： A seating unit includes a base having a housing and support arms extending laterally on each side of the housing. A back frame is pivoted to the support arms on each side, and a slide slidably engages the housing. A seat-supporting structure includes a crossbar pivotally attached to the slide member at a first pivot location and side frame sections extending rearwardly from ends of the crossbar that are pivotally attached to the lower arms of the back at a second pivot location spaced horizontally from the first pivot locations to define a three-point support for a seat above the housing. A spring is operably coupled to the slide to bias the back and seat toward upright positions.

摘要： A seating unit includes a perimeter frame, a flexible seating surface supported by the frame, and parallel elongated resilient force-distributing members coupled to the seating surface to control a contour of the seating surface when supporting a seated user. The resilient force-distributing members are bendable along their length and are sufficient in number and distribution to substantially reduce localized deflection of the seating surface and thereby reduce pressure point contact felt by the seated user. The resilient force-distributing members can be wire rods, long strips, or other resilient material with memory. The resilient force-distributing members can be supported on opposing sides of the perimeter frame in various ways to reduce inward pressure on the opposing sides during flexure of the resilient force-distributing members, such as by providing on ends of the resilient force-distributing members one or more rotatable pivots, sliding support at ends of the resilient force-distributing members, stretchable rubber supports, and/or elastic fabric.
摘要翻译： 座椅单元包括周边框架，由框架支撑的柔性就座表面以及平行细长的弹性力分布构件，其联接到座位表面，以在支撑就座的使用者时控制座位表面的轮廓。 弹性力分布构件沿其长度是可弯曲的并且在数量和分布上是足够的，以便基本上减小座面的局部偏转，从而减少由坐着的使用者感到的压力点接触。 弹性力分配构件可以是线材，长条或具有记忆的其它弹性材料。 弹性力分配构件可以以各种方式支撑在周边框架的相对侧上，以在弹性力分布构件弯曲期间减小相对侧上的向内压力，例如通过在弹性力分配构件的端部上设置 一个或多个可旋转的枢轴，在弹性力分配构件的端部处的滑动支撑件，可伸缩橡胶支撑件和/或弹性织物。

摘要： A back construction includes a back shell mounted on a back frame at top and bottom connections, and a flexible lumbar section biased forwardly by a biasing device. The bottom connection is located rearward of the back shell to allow unencumbered sliding entry into the seating unit from a lateral side position, but the bottom connection defines a virtual pivot forward of its physical location to provide the desired path of flexure when the lumbar section is flexed. In one form, the bottom connection is a pair of non-parallel links of dissimilar length. In another form, the bottom connection is a follower with two bearings following a guide slot. In some variations, the force of the biasing device is variable. Seating units incorporating the back construction include a vehicle seat, a foldable portable stadium seat, and a wheelchair seat.

摘要： A seating unit includes a seat, a back, and a support structure supporting the seat and the back. A wheelchair base frame includes a beam extending transversely across the wheelchair base frame. An adjustable extendable column extends between the beam and the support structure for adjustably supporting the seating unit on the wheelchair base frame. The support structure and/or the transverse beam can be constructed to receive the same structure as is provided on a standard task chair. By this arrangement, a plurality of similar chairs can be ordered, some having standard bases and others having a wheelchair base. Concurrently, the seating unit with the wheelchair base can include substantially all options and styling offered in the standard task chair.

摘要： A back construction for seating includes a back frame having an elongated section and a non-uniformity caused by a molding gate in a center of the elongated section. An aesthetic cover is configured to overlay a portion of the elongated section and snappingly engages the elongated section to cover the non-uniformity. A back shell is connected to the back frame by a connection that includes internal connecting structure providing strength to the connection. A housing surrounds the internal connecting structure too provide an aesthetic appearance to the connection. The back shell has a channel defined along its bottom edge, and an elongated bracket has an intermediate section shaped to fit into the channel. The bracket is retained in the channel by a nose-shaped top edge and bottom screws, such that the bracket is easily assembled yet securely held.

摘要： A magnetic braking, governing, or speed retarding system for use with a wheeled conveyance may take advantage of eddy currents induced when a magnet moves past a non-magnetic conductor. A plurality of magnets may be disposed within a rotor that rotates as a wheel axle rotates. The magnets rotate past one or more relatively stationary stators to generate eddy currents that create a resistance on the rotor, thereby acting to retard or slow the rotational speed of the rotor and the axle. The system may be particularly well-suited with a wheeled conveyance such as a sled that is gravity driven and travels downhill along a track. The speed governing system may apply lesser force in relatively flat sections of the track, due to slower wheel rotational speeds, and greater force as the conveyance attempts to pick up speed, e.g., in steeper sections.
摘要翻译： 用于轮式输送的磁性制动，调速或减速系统可以利用当磁体移动经过非磁性导体时所引起的涡流。 多个磁体可以设置在随着轮轴旋转而旋转的转子内。 磁体旋转经过一个或多个相对固定的定子，以产生在转子上产生电阻的涡流，从而用于延迟或减慢转子和轴的旋转速度。 该系统可能特别适合于轮式输送机，例如重力驱动并沿着轨道下坡的雪橇。 速度调节系统可能由于较慢的车轮转速而在相对平坦的轨道部分施加较小的力，并且当输送机尝试拾取速度时，例如在较陡的部分中，该力就会变大。
