A portable assistive device that is primarily for use with chairs that do not have armrests, such as kitchen or dining room chairs, comprising at least two support members, with at least one support member removably attachable to either side of the chair.

A displacement auxiliary device for an accessory of a chair is revealed. The auxiliary device is disposed on the chair and used in combination with the accessory of the chair such as an armrest, a lumbar support, a headrest, etc. The auxiliary device includes a displacement member, a fixing plate and a loading plate. The displacement member further includes two rotating members that are rotated a large angle around two rotary shafts respectively and symmetrically to be moved inward to a first position or extended outward to a second position. The accessory of the chair stays still without displacement when the two rotating members are moved inward to the first position. The accessory of the chair moves synchronously while the two rotating members are extended outward to the second position. Thereby the accessory of the chair can be adjusted to have larger displacement.

A lifting structure for an armrest mounted on a left side or a right side of a chair contains: an accommodation sleeve, a fixer, a swing arm retained in one of multiple recesses of the fixer via a slidable seat, an extension located between two drive members of the swing arm and accommodated inside a receiving tab of the slidable seat, and a connection plate covered on the accommodation sleeve so that the fixer is connected with a holder, and the connection plate is coupled with an armrest seat, thus connecting the armrest. The accommodation sleeve includes two concave seats. The fixer includes a groove and two closed slots. The slidable seat includes the receiving tab, two ribs extending, two cutouts, and two elongated orifices. The swing arm includes a coupling rod, an oblique hole, a locking projection, a column, and an indentation.

A height adjustable chair armrest includes an armrest top portion and a supporting member coupled with a chair body. The supporting member includes an outer tube and an inner tube received in the outer tube. The inner tube includes a plurality of positioning holes. A resilient member is mounted in the inner tube and includes a body and a resilient plate slantingly branching from the body. A first peg is disposed on the body and is releasably engaged in one of the plurality of positioning holes. An actuation rod is insertable through the outer tube into an operational hole of the body to press against or release the resilient plate. A rib is disposed on an inner periphery of the inner tube and is spaced from a top end of the inner tube by a spacing. The resilient member is restrained at a side of the rib.

An elevating structure includes an armrest support, a telescopic sleeve, and a pressing member. The armrest support has a fixing base for being fixed to a seat's underside of a chair and a tube. An upper portion of a side of the tube is formed with a positioning aperture with toothed notches. The telescopic sleeve sheathes the tube and is formed with a receiving trough. Two opposite edges of the receiving trough are separately formed with pivoting recesses. A bottom of the receiving trough is formed with a via hole. The pressing member is formed with a positioning protrusion passing through the via hole to engage with one of the toothed notches. An elastic member is disposed between the receiving trough and the pressing member to provide an outward push to the pressing member.

A torso supporting chair having a chair and front support. The chair has a seat support and at least one leg. The seat support having a top side and a bottom side, with the at least one leg attached to the bottom side. A front support is in functional combination the chair and may be integrally mounted with the at least one leg such that the front support is configured for seating of a user such that when the user is seated the chest of the user is adjacent and facing the front support. The torso support chair is configured to support the front torso of a user when seated.

An inclination-adjustable armrest (10) includes a pivot bearing (12) formed at one end of the armrest, the pivot bearing defining a pivotal axis (A) for the armrest, a clamping-type locking mechanism (16) arranged on the pivotal axis and being adapted to be unlocked by a release member (20) that is rotatable about the pivotal axis, and an actuating mechanism for actuating the release member, wherein the actuating mechanism has a release lever (22) that is connected to the release member (20) and is rotatable about the pivotal axis (A) and which extends through the interior of the armrest (10) to the end of the armrest opposite to the pivot bearing (12) and exits the armrest at that opposite end.

The present invention relates generally to furniture, and more particularly to a chair, particularly a lounger chair, wherein at least one side arm portion of the chair is provided with a lower fixed arm segment, and an upper slidably movable arm segment. A storage receptacle for holding various devices, such as, for example, a book, magazine, remote control devices, a wireless charging pad, a dock, is fixedly secured within the lower fixed arm segment. Alternatively, the storage receptacle can comprise at least one cup holder for holding a beverage. The upper slidably movable arm segment is fixably mounted upon a slidable rail member, and a motorized mechanism is operatively connected to the slidable rail member for moving the slidable rail member and the upper arm segment fixedly secured thereto between a first forward position at which the upper arm segment is CLOSED so as to cover the storage receptacle or cup holder such that, for example, the storage receptacle or at least one cup holder is hidden from view, and a second rearward position at which the upper arm segment is OPEN so as to uncover the storage receptacle or cup holder such that access to the storage receptacle or at least one cup holder is permitted.
