Accordingly, the chair chassis according to the embodiments of the present disclosure achieves reclination memory adjustment of a backrest of the chair.

An electrically controlled chassis includes: a chassis body; an electrical control box, internally provided with an accommodation space; a drive motor, configured to control lift adjustment of the chassis of the chair and pitch adjustment of a backrest of the chair; a winding mechanism, connected to an output shaft of the drive motor; a first pull cord, reversely wound on the winding mechanism; a second pull cord, normally wound on the winding mechanism; a backrest adjustment mechanism, disposed on the chassis body, and fixedly connected to the other end of the first pull cord; and a chassis lift mechanism, disposed on the chassis body, and fixedly connected to the other end of the second pull cord.

A gaming chair with audio output. The gaming chair includes a movable stand member, a seat member, a backrest member, a plurality of speakers, a Bluetooth transmitter, a power supply, and an inverted triangle wiring. The seat member is disposed over the movable stand member. Further, the backrest member is hingeably coupled to the seat member. Furthermore, the inverted triangle wiring is adapted to electrically couple the plurality of speakers, the Bluetooth transmitter and the power supply to enable an electrical connection therebetween.

An exercise chair allows a user to obtain physical exercise at his or her desk or other workplace. An exemplary exercise chair may include a frame, including a base, an angled section angled upward from the front of the base, and a back support extending upward from the rear of the base; a seat support rotatably connected to the angled section; and at least one resistance element connected to a rear portion of the seat support and to the back support.

An electronic gaming system is described. The electronic gaming system includes an upper assembly including a chair and at least one sensor. The electronic gaming system also includes a lower assembly coupled to the upper assembly by a support structure wherein the lower assembly includes a centering system and wherein the centering system is configured to return the chair to a predefined home position in response to the at least one sensor of the upper assembly detecting a weight below a predefined threshold.

A chair chassis includes: a base, provided with an accommodation chamber; a backrest support; a memory stopper, disposed on the backrest support, wherein the memory stopper is provided with a first arc surface facing the base; a locking slider, slidably disposed in the accommodation chamber of the base, wherein the locking slider is provided with a second arc surface disposed opposite to the first arc surface, and a side of the locking slider is provided with a first rack; a first elastic member; and an elastic slider, slidably disposed in the accommodation chamber of the base, wherein one end of the elastic slider is provided with a second rack, wherein the second rack is meshable with the first rack. Accordingly, the chair chassis according to the embodiments of the present disclosure achieves reclination memory adjustment of a backrest of the chair.

The present application relates to a shop chair with a seat cushion supported by a strong, light-weight base assembly with an elevated central hub that threadably receives a central column to adjust the height of the seat cushion. The base includes several vertically oriented thin plate legs that extend radially outward and downward from a central hub. The outer ends of the legs are joined by a stabilizing ring with a diameter larger than the seat cushion. Oversized caster wheels and the large footprint of the base provide a stable work platform. The seat cushion can be selectively lowered until the bottom of the central post is proximal to or contacts the ground. The chair and its base are particularly suited for work done closer to the ground.

The invention relates generally to a lightweight, collapsible, and portable wheeled seat, e.g., a wheeled office chair or stool, for travel, storage, and mobility. The seat includes a seat base member and a seat surface member collapsible between an open, extended position, which is configured to provide a seating surface, and a collapsed, closed position. The seat surface member includes a central seating surface member fixed to the seat base member that has an outer perimeter, and a pair of oppositely disposed and generally u-shaped seating surface members pivotally secured to the seat base member. Each of the generally u-shaped seating surface members include a pair of leg portions that extend from a base portion thereof, or an inward directed perimeter and a portion of each inward directed perimeter has a shape that substantially complementarily corresponds to a shape of a portion of the outer perimeter of the central seating surface member.
