A chair includes a lower back frame, a back construction, including a back support attached to the lower back frame, a cushion assembly attached to the back support and a clip wedgingly engaged between the back support and the cushion assembly. The cushion assembly further includes an inner shell which includes two or more apertures and a hook extending downwardly and outwardly from each aperture. The clip further includes at least one angled ramp and at least one stop. The angled ramp is configured to allow the hook of the inner shell to slide through the angled ramp and the stop is configured to suspend sliding of the hook. Methods of assembling a back construction are also provided.

A semiconductor die including a test structure is provided. The semiconductor die includes a loop-back formed on a surface of the semiconductor die. The loop-back structure includes a first bonding pad on a first surface; and a second bonding pad on the first surface, wherein the first and the second bonding pads are electrically disconnected from integrated circuit devices in the semiconductor die. A conductive feature electrically shorts the first and the second bonding pads. An additional die including an interconnect structure is bonded onto the semiconductor die. The interconnect structure includes a third and a fourth bonding pad bonded to the first and the second bonding pads, respectively. Through-wafer vias in the additional die are further connected to the third and fourth bonding pads.

An aircraft passenger seat configured in accordance with an embodiment of the invention utilizes composite materials to achieve significant weight savings relative to conventional seat designs. The seat includes one or more lightweight composite support legs, a lightweight composite seat pan, and a lightweight composite seat back structure. The support legs are coupled to the seat pan, which is in turn coupled to the seat back structure. The support legs utilize composite frame elements that are formed as continuous compression molded composite extrusions. The seat pan includes composite fore and aft cross beams that are also formed as continuous compression molded composite extrusions. The aft cross beam includes a rear flange that serves as a flexible “hinge” for the seat back structure. The seat can leverage producible and relatively inexpensive composite manufacturing techniques such that the seat can be economically produced for use as an economy class seat.

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.

A seating unit is provided having a base, a back frame pivoted to the base for movement between upright and reclined positions, and a seat slidably supported on the base assembly and pivoted to the back frame so that the seat moves forwardly and its rear moves forwardly and downwardly with the back frame upon recline. A flexible back shell is connected to the back frame at top and bottom locations for controlled flexure when a seated user reclines and / or flexes his / her back, and is provided with lumbar adjustment for improved lumbar force / support and shape.

In a seat back with movable headrest, a pressure receiving element is movably provided, which includes pressure receiving regions for receiving loads applied from lumber and dorsal parts of seat occupant. The pressure receiving element is movably connected with a crank member which is movably provided between two lateral frame members of seat back frame. Further, that pressure receiving element is connected with a support shaft extended between a par of rotating links rotatably arranged on the respective afore-said two lateral frame members. A biasing element is provided to normally bias the headrest to a home position.

Structure of seat back is provided, which comprises: a seat back frame; and an upholstery cover assembly including a forward upholster cover element and a backward upholstery cover element. Those two upholstery cover elements cover respective forward and backward sides of the seat back frame, with an upper region thereof secured on top portion of the seat back frame by a headrest stay holder element. Outer peripheral ends of those two upholstery cover elements are engaged together by an engagement element, so that substantially a whole of the seat back frame is covered with the upholstery cover assembly, thus forming a seat back.

A rack structure for a chair includes a chair back member having a frame and a mounting support. The frame includes a support cushion disposed on the front side thereof for supporting a user's waist correspondingly. The frame further includes two first connecting tabs fixed on the back sides of the top ends of two sides thereof individually and two second connecting tabs formed on and extending from the two sides thereof respectively. The mounting support is fixed onto a base and extends upwardly therefrom. The mounting support includes two coupling segments and two connecting projections arranged on the top ends and the intermediate sections of two sides thereof respectively. Between each coupling segment and each connecting projection is couplingly attached a resilient member. The first and second connecting tabs of the frame are connected with the coupling segments and the connecting projections of the mounting support individually.

A shaver comprising a handle with an elongated handgrip portion and a mounting portion, a shaver head attached to the mounting portion, the shaver head having a back structure. A removable cartridge is attached to the shaver head through an elastic member provided on the back structure of the shaver head.

A pivoting mechanism with gross and fine adjustment with a housing, an elongate shaft pivotally retained by the housing, resiliently deformable members retained by the housing, cam members coupled to the shaft wherein the cam members are disposed to deform the resiliently deformable members when the cam members are pivoted, and a locking slide bar for selectively causing the cam members to pivot with the shaft to produce gross adjustments in pivoting resistance. First and second ends of the shaft can act as an output interface for outputting the pivoting resistance exhibited by the shaft to a seat back structure, a seat bottom structure, or some other structure. A threaded rod rotated by a handle can adjust an initial deformation of the first resiliently deformable member for fine pivoting resistance adjustment.

A chair with a control mechanism with a base structure, a seat bottom structure supported by the base structure, a seat back structure supported by the base structure, a control mechanism supported by the base structure, a power source and means for electrically coupling the power source to the control mechanism and an electrical port, wireless transmitter, or other electrical communicator for producing electrical communication relative to the control mechanism. The power source can be a portable power source that plugs into the connector of the control mechanism. One or more electrical sensors can be retained relative to the seat bottom or seat back structures and memory can be provided for retaining data from the electrical sensor.
