摘要： The present invention relates to a tiltable chair including: a fixing base having a tiltable housing disposed on an upward protruding dome-shaped center thereof in such a manner as to be movable in an arbitrary direction; a gas cylinder disposed inside the tiltable housing in such a manner as to be linearly reciprocated in upward and downward directions; a seat plate disposed on top of the gas cylinder; and an elastic tiltable member disposed inside the fixing base in such a manner as to accommodate a longitudinal lower part of the gas cylinder therein to allow the gas cylinder to move tiltably about vertical axis to the bottom of the fixing base, wherein the elastic tiltable member includes a fixed frame located on the bottom of the fixing base, a coupling frame located inside the center portion of the fixed frame to accommodate the gas cylinder therein, and a rubber packing located between the fixed frame and the coupling frame and deformed elastically in every direction, wherein the rubber packing has tilt concave grooves formed inward to a given depth from top and underside respectively in such a manner that the tilt concave grooves are reduced in width toward the insides thereof to thus form inclined surfaces.
Accordingly, the tiltable chair is configured to have the elastic tiltable member for accommodating the gas cylinder therein, instead of a large number of coil springs complicated in structure in the conventional practice, so that the tiltable chair can be made simple in structure, thereby preventing the generation of noise when tilted.-

摘要： Joystick chair is an input device for interaction between the user and computer. It enables the movement of the user in games. The invention is used by placing feet on the platform (3) and sitting or leaning on the seat (23). Command for turning is achieved by rotating the seat (23), either to the left or to the right. Command for forward movement is issued by pulling the left or right controller (36, 41) with fingers, while the command for backward movement is issued by pushing the left or right controller (36, 41) away by palms. Control handles for lateral movement (49, 56) are separated from the forward-back controls that are located on the controllers (36, 41). Other commands are achieved with buttons on the left and right controller and they are accessible with thumbs. The software allows the modifications of all available actions of the invention.

摘要： A stool and desk support system. The system includes a stool base and a desk support surface. A support member may connect the desk support surface to the stool base and support the desk support surface above a floor surface. The stool base may include a stool seat surface and a rocking mechanism opposite the stool seat surface. The desk support surface may be connected to a desk support base by a neck extending from the desk support base. The stool base may include an upper stool base frame and a lower stool base frame. The upper stool base frame may be height adjustable with respect to the lower stool base frame. The desk support base may connect to the upper stool base frame, permitting coinciding height adjustment of the desk support surface and the upper stool base frame.

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 seating furniture includes a seat with a seat surface, a pedestal and a tilt mechanism. The tilt mechanism is disposed between the pedestal and the seat and permits an inclination of the seat surface of the seat relative to the horizontal. In addition, the tilt mechanism has a lower bearing block mounted to the pedestal, and an upper bearing block fixedly connected to the seat. The lower bearing block has a convexly curved lower bearing surface on its upper side facing the upper bearing block, and the upper bearing block has a concavely curved upper bearing surface on its lower side facing the lower bearing block. The lower and upper bearing surfaces have substantially corresponding radii of curvature, so that the upper bearing block can be moved relative to the lower bearing block along the upper bearing surface. A tilt mechanism for seating furniture is also provided.

摘要： A mechanism for adjusting vertical seat position using a single extremity and requires no user weight to lower. The mechanism features a seat with an integrated grip for lifting. A spring-loaded latch obstructs the teeth to prevent seat lowering without rotation of a handle. The latch pivots out from obstructing the teeth when lifted. To lower the user rotates the handle to disengage the latch, causing the seat to lower under its own weight. At the desired height, the user releases the handle to permit the latch to obstruct downward movement. A gas spring may counter-balance to reduce overall effective seat weight, making the seat easier to lift while still allowing the seat to lower under its own weight upon rotating the handle. The mechanism for horizontal adjustment couples to the handle, which displaces a cable that disengages a pin allowing the seat to move horizontally on a track.

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.
