An armrest (8, 208) and a chair (100, 200) according to the present invention are provided with: an armrest body (8b, 208b) which is a movable member including a placing surface for supporting a limb of a seated person, and which is supported by a support rod (8a, 208a) from below so as to be movable in a horizontal direction; and a through-space (S, 200S) which is a guide portion indicating the position to be touched by the seated person when moving the armrest body (8b, 208b).

A ventral support for use in an ergonomic work station chair, the ventral support comprising an adjustable Y axis member and a support unit, the support unit pivotally and extendibly attached to the adjustable Y axis member, wherein the support unit is heart-shaped and includes a rear, a face, and a top therebetween, the face including a right lobe and a left lobe, a clavicles support, which has a right side and a left side, is raised, is proximate the top and is horizontally disposed, and a central ridge, which extends vertically downward from the clavicles support, wherein the right lobe, the right side and the central ridge define a right concavity in the face and the left lobe, the left side and the central ridge define a left concavity in the face.

A tablet including a plate member, a support rod and a positioning member is revealed. The plate member has a top cover, a bottom cover, and a first slide member. By the movable engagement of a rack with a damper, the top and the bottom covers slide relative to the first slide member. The support rod includes an upper end for supporting the plate member and a lower end assembled on a chair, a bed, a sofa, a table, a tray with wheels or a multi-seater chair. The upper end forms a rotary shaft which is inserted through an insertion hole of the bottom cover to be fixed on the first slide member. The positioning member includes a movable locking pin member. The angle of the plate member can be adjusted by the locking pin member being released from or locked into a positioning hole on the rotary shaft.

A device for adjusting the position of an armrest of a chair, which comprises a clamp, stably associated with the chair, which interacts selectively with a vertical position selector, associated with a box-like body which constitutes the armrest. The vertical position selector is actuatable by virtue of means which can be activated by the user and comprise a slider which can slide below the armrest and is adapted to activate/deactivate the actuation of the vertical position selector

A chair includes a back member and arm brackets. The back member is tapered toward an end that is adjacent to a seat. The arm brackets are attached under a bottom portion of the seat. Each arm bracket is adjustable to provide a seat clearance area for the seat when one or more of the arm brackets are adjusted up to approximately 90 degrees from an original upright position.

The present disclosure provides a chair with a rotatable armrest, comprising a seat body, which is provided with an armrest, a backrest and a rotating member; wherein the backrest is arranged at a position on one end portion of the seat body, the rotating member is fixed on one end of the seat body near the backrest, the armrest is rotatablely connected with the seat body through the rotating member, and the armrest is capable of rotating roughly horizontally with respect to the seat body. According to the present disclosure, a user can leave the chair from one side of the seat body, moreover, when the user is leaving the chair, the rotated armrest can still provide help for the user.

An adjustable armrest includes a post and an armrest body. A sliding member is coupled to the post and has a non-circular contour on a horizontal plane. The armrest body receives a sliding seat. The sliding seat includes a track extending in a length direction. The sliding member is received in the track. The armrest body is movable relative to the post. The track includes a first section and a second section interconnected to the first section. The first and second sections are arranged in the length direction. The first section extends along a rectilinear line. The second section extends along a non-rectilinear line.

A chair armrest is revealed. The chair armrest includes an armrest support, an armrest pad body, a connection body, and a connecting member. The armrest pad body has a mounting slot with an opening facing downward while the mounting slot has a depth and a shape. The connection body is provided with a thickness and a shape which are corresponding to the depth and the shape of the mounting slot. Thus the connection body can be mounted and positioned in the mounting slot. The armrest support and the connection body of are connected by the connecting member. During assembly of the chair armrest, the armrest support is connected to the connection body by the connecting member while the armrest pad body is affixed with the armrest support into one part by the connecting member. Thereby production cost is reduced.

An armrest according to the technology described herein includes a bracket, an armrest body, a device connecting port, an armrest-side connector, and a cable. The bracket is fixed to a seat frame. The armrest body is attached to the bracket to be rotatable. The device connecting port is exposed through an outer surface of the armrest body. The armrest-side connector is fixed to the seat frame at a position different from the bracket. The cable includes an end connected to the device connecting port and an end connected to an armrest-side connector. The armrest body includes a cable retaining portion through which the cable is passed and in which the cable is retained. Any one of the bracket and the armrest body includes a hole (an elongated hole) that allows movement of the cable along with rotation of the armrest body.

An armrest includes a bracket fixed to a frame of a seat, an armrest body member rotatably mounted on the bracket, a receiver coil mounted in the armrest body member, and a transmitter coil mounted in the bracket and transferring power to the receiver coil with a non-contact transmission system.
