摘要： A chair (1) includes an installation base (10), a leg column (11) supported by the installation base (10) in a tillable manner, a seat body (12) supported on an upper part of the leg column (11), an elastic member (19) which urges the leg column (11) to an initial tilted posture, and a coming-off restriction member (22) which restricts coming-off of the leg column (11) from the installation base (10). On a support wall (16) of the installation base (10) having an insertion hole (20) through which part of the coming-off restriction member (22) is inserted, a slide guide (21) coming into slidable contact with a slide guide (21) at a peripheral edge portion of a lower surface side of the insertion hole (20) is provided. The coming-off restriction member (22) has an upwardly protruding spherical guide surface (23) which is slidably brought into contact with the slide guide (21) below the insertion hole (20).

摘要： An item of seating furniture, in particular an office chair, having a pedestal with a support column on which a first rotational axis for a backrest is arranged which is pivotable between an upright starting position and a reclined resting position. The backrest is articulately connected in its lower region to a seat part, and when the seat part is in one piece, the articulatable connection is provided about a second axis.When the seating furniture is in the upright starting position, the second axis is arranged below the first axis. The rear seat part is non-rotatably connected to the backrest. The front seat part or the one-piece seat part is supported by kinematicsin relation to the carrying frame. The front seat part or the one-piece seat part is lowered relative to the rear seat part or the backrest by means of kinematics when the backrest is pivoted back.

摘要： A tiltable stool includes a seat support, a seat, and a tilt mechanism. The seat is mounted to an upper end of the seat support. The tilt mechanism allows the seat to tilt in a desired direction. The tilt mechanism includes a coiled wave spring, an upper spring retainer and a lower spring retainer, a fastener bolt, and a tilt limiter. The upper spring retainer and the lower spring retainer are disposed opposite each other to sandwich the coiled wave spring therebetween. The fastener bolt pivotably holds the upper spring retainer in position. The tilt limiter is disposed inside the coiled wave spring and is secured to either one of the spring retainers. The tilt limiter includes a conical surface thereon which contacts a contact surface when the seat tilts to a predetermined tilt angle. The upper spring retainer is secured to a lower end of the seat support.

摘要： A chair is disclosed herein of the kind that is shipped disassembled in a compact shipping package to be assembled by the end user without the use of tools. The chair has a pair of user actuated height and tilt control paddles by which the elevation of the seat and the tilt of the seat and back of the chair can be adjusted relative to the base which holds the seat above the ground. In one embodiment, the height and tilt control paddles are removably attached to the seat at respective paddle receivers connected to the bottom of the seat. In another embodiment, the height and tilt control paddles are removably received by respective paddle cavities formed in the arms of the chair. By removing the paddles from their paddle receivers or paddle cavities, the parts of the disassembled chair may be more efficiently packaged for shipment.

摘要： A chair can include a chair back, or backrest, that is coupled to a base of a chair above a seat of the chair. A tilt mechanism can attach the backrest to the base at spaced apart locations. In some embodiments, the tilt mechanism can be configured so that the backrest rotates about multiple pivots as it reclines from an upright position to a reclined position to drive forward motion of the seat during recline of the backrest.

摘要： Disclosed herein is a chair of the kind that is shipped to a user disassembled. The chair includes at least one chair function controller (i.e., a paddle) that is actuated to control a chair function operator (e.g., a gas cylinder located below and coupled to the chair seat). During assembly, a pair of cable sections are mechanically and serially connected to one another at a force responsive connector block that is located within and slidable through a cable connector housing at the bottom of the chair seat. By virtue of connecting the first and second cables together at the connector block, the chair function controller paddle is connected to the chair function operator so that an actuation of the controller causes a pulling force to be applied to the chair function operator to enable the seat or back of the chair to be displaced.

摘要： Method and apparatus for improving sound quality in audio cables, including a plurality of equally spaced conductive discs separated by a gap and configured in a generally linear array, each of the discs having an annular shape with planar sides, an outer diameter, a center hole having a diameter, and a thickness. The disc array is placed around an audio signal cable such that the planar sides of the discs are oriented parallel to one another and perpendicular to signal cable axis. The spacing between discs is approximately four to ten times the thickness of said discs, and the disc diameter is between 2 and 4 times the diameter of the center hole.
