An armrest release mechanism includes a pivot bush. A release bracket is fixed to the pivot bush. An armrest pivot is supported on the pivot bush for relative rotational movement. A release board is also supported on the pivot bush for relative rotational movement. The release board is movable between a locked position and an unlocked position. An armrest lock is attached to the release bracket for relative movement. The armrest lock is also attached to the release board. When the release board is in the locked position the armrest lock is engaged with the armrest pivot to prevent movement of the armrest pivot relative to the pivot bush. When the release board is in the unlocked position the armrest lock is not engaged with the armrest pivot.

A rotatable armrest includes a shaft to allow the arm pad to rotate and a locking mechanism defining a set of stopping positions. The profile of the arm pad is defined to clearly delineate portions of the expanded arm pad for each passenger. The rotatable armrest may also include a cam driven divider that extends from the arm pad as the arm pad is rotated to further define delineate portions of the expanded arm pad for each passenger.

An apparatus that supports a user in a variety of positions to comfortably perform tasks, such as applying one or more tattoos to skin of a subject is herein disclosed. The apparatus can be reconfigured to optimally position and support the arms and/or chest of the user. The apparatus includes a vertically movable armrest assembly. Armrests can support the user's forearms while supporting the user's chest such that the user can comfortably perform tasks in front of a chest support of the stool. The armrest assembly can be translated vertically to accommodate the user's body to achieve desired positioning.

The invention relates to a chair, having a chair base (1), a seat part (5, 6, 7, 8) connected thereto, a backrest (9, 16, 17) connected thereto, the seat part (5, 6, 7, 8) pivotable about at least one horizontal or inclined horizontal axis and the backrest (9, 16, 17) are spatially adjustable. The seat part (5, 6, 7, 8) has at least three seat elements (5, 6, 7) that can be adjusted in relation to one another and whose operating positions can be adjusted individually.

An armrest pad assembly includes: an armrest pad, wherein the armrest pad includes a first support section, a bendable section, and a second support section that are successively connected along a lengthwise direction of the armrest pad; wherein the armrest pad is internally provided with a first inner frame and a second inner frame, the first inner frame being fixed to the first support section, and the second inner frame being fixed to the second support section; wherein the first inner frame and the second inner frame are configured to be connected to an armrest frame of a chair, such that during upward and downward folding adjustment of the armrest frame of the chair, the first inner frame and the second inner frame drive the first support section and the second support section to be folded upward and downward about the bendable section to a predetermined position.

A posture correction mechanism includes a carrier attached to a housing, and a gearwheel rotatably attached to the housing, the gearwheel includes a screw hole engaged with a screw which is moveable up and down relative to the housing for driving the gearwheel to rotate relative to the housing, two shafts are rotatably attached to the carrier and each has an arm rest, two gears are rotatably attached to the carrier and engaged with the gearwheel, the gears are connected to the shafts for allowing the shafts to be driven by the gearwheel to rotate relative to the carrier and for allowing the arm rests to be rotated toward or away from the user.

A foldable massage chair, including a face pillow assembly for supporting the head, a chest pillow assembly for supporting the chest, a handrail assembly for supporting wrists, a front support piece, a seat cushion assembly, a back support rod, a kneeboard assembly, a back supporting frame, and a front supporting frame. When a user needs to use this chair, it is placed in an expanded or use position, so the user may sit on the seat cushion and lean on the massage chair, completely exposing his back, waist, and hips for a masseur to massage. When the chair needs to be put away, it is possible to fold down the chair into a collapsed position by folding the seat cushion assembly, front support piece, chest pillow assembly, and handrail assembly. Also, the front supporting frame is folded towards the back supporting frame. Consequently, the size of the entire chair decreases.

A mechanism for raising and lowering an armrest for a seat includes an armrest, a rotatable hub, and an actuating linkage between the armrest and the hub, the rotatable hub having a cam that operates the actuating linkage to raise the armrest wherein the cam can rotate through a first angle of rotation where the actuating linkage is not operated a second angle of rotation where the actuating linkage is operated. The cam can rotate through a third angle of rotation where the actuating linkage is not operated, this angle being different to the first angle of rotation. The cam is torsionally linked to the rotation of a seat member.

A locking device for an armrest pole. The locking device comprises a housing element configured for slidably accommodating the armrest pole. A locking handle comprises an abutment end, the locking handle is rotatably connected to the housing element and configured for rotation between a locked position where the armrest pole is fixed in the locking device and an unlocked position where the armrest pole is slidable in the locking device. The locking device also comprises a wedge element comprising a wedge and an abutment portion, the abutment portion configured for being directly or indirectly biased by the abutment end, the wedge configured and arranged for at least partly insertion between a portion of the armrest pole and at least a portion of the housing element in the locked position.

A console mounted armrest includes an adjustable post to raise and lower the armrest, and a linkage. The linkage defines the tilt of the armrest with respect to the post. A single control mechanism controls the motion of the post, and thereby also controls the tilt of the armrest to maintain a desirable orientation with respect to the sidestick. The control mechanism defines multiple positive lock-out positions with respect to the post such that the control mechanism will always engage one of the positive lock-out positions.
