A chair according to the present invention has a reference position P located midway in a front-back direction in a movable range of a seat 2. The chair includes a return force generation mechanism 4 configured to generate a return force in a direction to return the seat 2 moved from the reference position P at least in the front-back direction to the reference position P. The return force generation mechanism 4 includes an elastic member 40 configured to increase the return force in the direction to return the seat to the reference position P as the amount of movement of the seat from the reference position P increases.

The reversible chair comprises two articulated portions (1, 2) with respect to a support (3), both articulated portions (1, 2) being able to be placed in a first position, wherein the articulated portion (1, 2) is in a substantially vertical position, and in a second position, wherein the articulated portion (1, 2) is in a substantially horizontal position, the chair further comprising two stop plates (4, 5), each of which is joined in rotation to one of the two articulated portions (1, 2), said stop plates (4, 5) being separated from each other when the two articulated portions (1, 2) are in the first position and in contact with each other when one of the articulated portions (1, 2) is in the second position.

It provides a reversible chair that can be oriented in two different orientations and that is as simple and cheap as possible.

To provide a chair in which the seated person can perceive a comfortable sitting feeling even if sitting for a long time, and furthermore a high work efficiency can stably be maintained, a chair according to the present invention includes a support mechanism 2 interposed between a leg 1 and a seat 3, wherein the support mechanism 2 includes: a seat inclining mechanism Q as a seat inclining function configured to downwardly incline a tip side in an operation direction of the seat 3 when the seat 3 operates from a predetermined reference position (S), and further includes: a return-force generation mechanism configured to generate, in accordance with an amount of movement, a return force in a direction of returning the seat 3 having moved from a reference position (S) in a front-rear or left-right direction, to the reference position (S).

An apparatus for disposing waste at a seat comprising a seat body having a topside for supporting a user and an underside opposite to the topside. The apparatus comprises a moveable bottom portion mounted below the underside of the seat body on one or more arms configured to allow the moveable bottom portion to move between an open position and a closed position, a first waste bag support positioned below the underside of the seat body and a second waste bag support positioned on an upper side of the moveable bottom portion. Each arm comprises one or more springs for biasing the moveable bottom portion into the closed position.

A seat unit (4) for use in a stepped seating venue comprises a rear frame (11) having a fixed back support (17), a fold away seat pan (21) pivotally mounted with respect to the rear frame (11) on a pair of seat pan pivots (23) and forward of the rear frame (11) when in use. The seat pan (21) folds against the rear frame (11) when not in use. A second frame (25) to support feet is also pivotally mounted on frame (11) below the seat pan pivots (23). The second frame (25) moves in tandem with the seat pan (21) from an open position substantially parallel to the seat pan (21) when the seat pan is in use to a position against the rear frame (11) when the seat pan (21) is not in use.

Surgical robotic systems including a user console for controlling a robotic arm or a surgical robotic tool are described. The user console includes components designed to automatically adapt to anthropometric characteristics of a user. A processor of the surgical robotic system is configured to receive anthropometric inputs corresponding to the anthropometric characteristics and to generate an initial console configuration of the user console based on the inputs using a machine learning model. Actuators automatically adjust a seat, a display, or one or more pedals of the user console to the initial console configuration. The initial console configuration establishes a comfortable relative position between the user and the console components. Other embodiments are described and claimed.

A chair includes, a seat, a backrest separated from the seat, and an upper support frame to which the backrest is attached at a position higher than the seat. In the chair, the upper support frame includes a left side portin and a right side portions both extending forward at left and right sides of the seated person and a rear portion that continuously and integrally connects the left side portion and the right side portion. The left side portion and the right side portion are connected to side support bodies arranged on left and right sides of the seat to be tiltable, and the backrest is connected to the upper support frame to be tiltable rearward.
