An adjustable seat includes a carrier, a seat body, a first linking rod, a second linking rod, a sliding mechanism, and an adjustment block. The seat body is arranged on the carrier and includes a seat surface switchable between a first direction and a second direction. The first linking rod is hinged to the seat body and the carrier. The second linking rod is hinged to the seat body and the carrier. The sliding mechanism includes a slide rail and a slide block slidably engaged with the slide rail. The slide block is hinged to the seat body. The slide rail is hinged to the first linking rod and the second linking rod. The adjustment block is slidably coupled to the slide rail or the seat body for switching the seat surface between the first orientation and the second orientation.

A chair frame mechanism and a chair having the same are provided. The chair frame mechanism includes a movable component, a chair bracket, a leg component, a back component and a sequence component. The movable component is connected with the chair bracket. The leg component and the back component are pivotally connected with the chair bracket, respectively, and the back component is connected with the movable component. The sequence component is connected with the movable component and the chair bracket, respectively, and connected with the leg component and the back component by transmission, respectively. The sequence component is capable of controlling the chair bracket to move relative to the movable component along a preset trajectory, and orderly controlling the leg component and the back component to extend or fold relative to the chair bracket.

The invention relates to a seat device (1) comprising an underframe (2) and a seat (3) connected to the underframe (2) in such a way as to pivot about a seat axis (A1), there being provided means for elastically biasing the seat (3) in anti-clockwise rotation. The seat device (1) further comprises a lumbar part (42); rotationally secured to the seat (3), and a saddle (5) for supporting the top of the thighs of the user, the saddle (5) being connected to the front region of the seat (3).

A support for a piece of seating furniture provides an additional degree of freedom of movement. The support has a connecting unit fitted on a main body that connects to a supporting element of an underframe. The connecting unit has a mounting device for the supporting element, in particular a mount for the upper end of the supporting element. The connecting unit is fitted on the main body such that it is possible to alter the inclination of the main body relative to the supporting element. For that purpose the main body has a preferably convex contact base, which in the fitted state is contacted by a contact head of the connecting unit, with the abutment forming a non-planar contact rather than a contact over a surface area, in particular a punctiform contact.

An assembly for a chair and a chair including the same are provided. The assembly includes a body coupled to an upper portion of a leg of the chair, a pair of supports extending forward from opposite sides of the body and coupled to a bottom surface of a seating part, and a pair of connecting frames extending backward from the opposite sides of the body, bent upward, and shaft-coupled to the opposite sides of the body and the seating part. A tilting operation is performed to rotate downward the seating part and a backrest to adjust inclinations of the seating part and the backrest using a weight of a user applied to the seating part and elastic force of the support and the connecting frame.

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.

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.

A resistive motion support mechanism joined to a mounting surface and to a base shaft for providing resistive support to the mounting surface as the mounting surface undergoes one or both of rotational and tilt movement relative to the base, the motion support mechanism including a support bearing connected to the mounting surface and to the base shaft which permits one or both of tilting and rotational motion of the mounting surface relative to the base; a pivot ball functionally attached to a portion of the base shaft; a resilient ring within a housing circumscribing the base shaft such that the resilient member is compressed between the housing and the base shaft by the relative movement between the base shaft and the mounting surface to provide a resistive force on the base shaft to resist the one or both of rotational and tilt movement; and, various means for varying the resistive force.

An intelligent cooking operation method includes: providing a seat; forming, by a back of the seat, a swing connection by using a connecting rod; forming a lifting and rotating connection between a cushion of the seat and a base of the seat through a support rod; and sending, by a cook, one or more voice control commands of a kitchen appliance to a voice signal receiving module according to a cooking requirement, where a voice command recognition module recognizes the voice control commands and generates corresponding appliance voice command data, and a command transmission module sends a command signal to a command receiving module of the kitchen appliance that the voice control commands point to, to control the kitchen appliance.
