Abstract: 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.

Abstract: Seat assemblies and methods for fabricating seat assemblies are provided. In one example, a seat assembly includes a seat base portion. A seat backrest portion is configured to extend substantially upright from the seat base portion. An armrest sub-assembly is configured to move between a stowed position that is one of substantially within and laterally adjacent to the seat backrest portion and an extended position that is generally forward of the seat backrest portion. At least a portion of the armrest sub-assembly translates along an incline relative to the seat base portion during movement from the stowed position towards the extended position.

Abstract: An armrest for a motorcycle passenger, which permits one or both armrests to swing out to a side thereby accommodating a boarding passenger. Optionally, the armrests can be pivoted to rearward-facing orientation in order to form a rack behind a sissy bar of a motorcycle.

Abstract: An arm-rest device is constituted by including the following: an armrest body to be installed to a seat rotatably upward/downward; a ratchet mechanism including stationary-side first ratchet teeth, and movable-side second ratchet teeth rotating integrally with the armrest body; coiled springs for urging those in such a direction that they press one another; releasing cam units for releasing the ratchet mechanism from the meshing; elastic claws and a flanged portion for retaining that release; cut-offs for returning the ratchet mechanism to the meshing. And, the armrest body is made of resin, thereby integrally molding the second ratchet teeth at the time of its molding. It thus becomes an armrest device that is lightweight as a whole, whose assembly can also be done with less man-hour requirements, whose feeling of use is also satisfactory, and which is inexpensive and small in size.

Abstract: A detachable and adjustable armrest device for pews and sectional seating that can be quickly installed, moved, recessed and removed. The device includes an upper clamp that form-fits sectional seat backs and includes a plurality of adjustment fasteners that firmly secures the armrest to the top end of the sectional seat back. A vertical backboard extends down along the seat back at a common angle from the upper clamp assembly and provides a connecting point for the arm board. The arm board can be connected directly to the vertical backboard by an L-shaped bracket to provide a fixed height armrest. In an alternated embodiment, one end of the L-shaped bracket is connected to an axle that is affixed to the vertical backboard. When the arm board is lifted vertically, it pivots on the axle and can be held in a vertical recessed position of a lock pin.

In another aspect, a pair of armrests are joined to a cross member and a pair of spaced apart beams in a releasable engagement. In yet another aspect, a pair of beam members are fixedly joined with a cross member, which is pivotally connected to a link pivotally connected to the beams. A method of assembling a load support structure is also provided.

Abstract: An orthopedic back support for displacing a person's weight from the lower area of the spine by providing support for the upper torso and for use with a chair or seat having a seat base and a seat back. A flexible fabric cross piece is connected between vertical axillary support members to provide back support. The cross piece may include vertical channels or sleeves at opposite sides to receive and support the vertical members. The entire unit is portable and when in use facilitates unobtrusive intermittent use and easy ingress and egress from the seat to relieve discomfort after long periods of use. A rib band may be attached to the flexible fabric by means of hook and loop fabric strips such as Velcro to form a detachable connection. A hook strip is disposed on the back of the rib band and is adapted to cooperate with a mating soft loop strip on the forward side of the flexible fabric member which supports the user in a seated position by the combined action of the flexible fabric and rib band.

Abstract: A chair arm rest system containing a chair having a vertical chair member hingedly connected to a horizontal chair member. A base proximal to the vertical chair member is attached to the horizontal chair member. The arm rest post is spring-biased towards the horizontal chair member but pivots in opposition of the spring towards the vertical chair member. A distal end of the arm rest post is pivotally attached to the top end of the base. An arm rest surface is attached to a proximal end of the arm rest post. A first end of a sling is attached to the vertical chair member. A second end of the sling is connected to the arm rest surface. In operation, by moving the vertical chair member relative to the horizontal chair member, the sling self-adjusts and the spring-biased arm rest post pivots towards the vertical chair member.

Abstract: An arm rest assembly for a motorcycle passenger seat includes a vertically adjustable mount secured to the typical backrest behind the passenger seat. A U-shaped tubular member includes a medial portion rotatably secured in the mount, and arm rest cushions secured to opposed side arm portions. The U-shaped member is rotatable through an arc of approximately 180° about the axis of the medial portion, the range being limited by stop members joined to the medial portion. The side arm portions extend rearwardly to support baggage, or rotated to an upwardly extending disposition in which the passenger may mount or dismount the passenger seat, to a forwardly extending disposition in which the side arm portions extend to support the arms of the passenger and to provide side support for the passenger.

Abstract: A task chair is disclosed, including a base, a seat supported by the base, and a pair of uprights connected to the base and extending upwardly from the seat. A pair of armrests are attached respectively to the uprights, and are selectively positionable along the uprights in a manner in which the height of the armrests along the uprights is adjustable. A backrest is also selectively positionable along the uprights, and the height of the backrest with respect to the seat may be adjusted by moving the backrest upwardly or downwardly along the uprights. The armrests and backrest each include mount sleeves telescopingly slidable along the uprights, each of the mount sleeves including a user-operable adjustment mechanism which includes a lever having a portion thereof selectively engagable with one of a series of holes along the uprights.

Abstract: A task chair equipped with a mechanism for independently adjusting the height and width of support arms by the manual operation of a single adjustment knob. Each of the support arms includes a first arm portion and a second arm portion that are pivotally coupled by corresponding pivot joints. Each second arm portion carries one of a pair of arm pads. Each second arm portion may be inclined relative to the corresponding first arm portion for inclining the corresponding arm pad relative to a seat plate of the task chair. Each arm pad is joined with the corresponding second arm portion by a coupling mechanism that permits movement of each arm pad with two degrees of translational freedom and one degree of rotational freedom.

Abstract: A seat assembly having a seat frame arranged to support a cushion, a rotatable armrest, a threaded receiver mounted to either the seat frame or the armrest, a translation shaft coupled with the other of the seat frame or the armrest which includes a thread disposed on the outside surface of the shaft arranged to matingly engage with the threaded receiver. Rotation of the armrest relative to the seat frame causes the armrest to translate toward or away from the seat frame as the threads of the translation shaft engage with the threaded receiver.
