Adjustable To Multiple Use Positions Relative To Bottom Or Back Patents (Class 297/411.35)
  • Patent number: 10264893
    Abstract: On an article of furniture, a bearing assembly is disposed between an elongate central structure and a seat, which permits rotation between the seat and the base. A tablet is provided, which is connected to a tablet arm with a first cylindrical member, and the tablet arm is connected to the elongate central structure of the base with a second cylindrical member. The second cylindrical member is disposed around the elongate central structure with a flange at the upper end thereof. The bottom of the seat has a lobed friction bushing disposed such that the flange of the second cylindrical member contacts the lobed friction bushing and frictionally resists rotation of the tablet arm as the seat rotates 360 degrees relative to the base, leading the tablet to follow the seat as it rotates. A lobed friction bushing is also provided.

  • Patent number: 10058183
    Abstract: A headrest lifting mechanism is revealed. The headrest lifting mechanism is disposed on a seat back and including a lifting base, a bottom-side vertical support and an elastic positioning rod. A headrest is connected to an upper end of the bottom-side vertical support. A positioning end of the elastic positioning rod fixed on the bottom-side vertical support is moved downward into one of the slots of the lifting base owing to material elasticity when the bottom-side vertical support is assembled with the lifting base. Thus the bottom-side vertical support and the positioning end are slid and positioned together in the slots of the lifting base. The number of the parts is reduced and the assembly is simplified. This enables cost reduction and mass production.

  • Patent number: 8403418
    Abstract: A chair, includes a seat structure and a backrest structure arranged pivotally to the seat structure. An armrest is arranged pivotally to the backrest structure through a pivotal connection, and a link mechanism is journalled to the structures of the seat and the backrest, respectively, the link mechanism actuating and controlling the armrest to maintain its pivotal orientation in any pivotal position of the backrest relative to the seat. The armrest is adjustable in the length direction of the backrest through the pivotal connection which is arranged displaceable on the backrest structure, and the pivotal orientation of the armrest is controlled via a sliding engagement between a lever arm, adjoining the armrest at an angle thereto, and an actuator link included in the link mechanism and displaceable thereby with respect to the backrest so as to extend substantially in the length direction of the backrest in all its positions of displacement.

  • Patent number: 8348205
    Abstract: An expandable armrest of a wheel chair includes a fixed part having a first pivotal portion which includes a first pivotal hole. A movable part is pivotably connected to the first pivotal portion of the fixed part by its second pivotal portion. A first transverse hole and a second transverse hole are defined in the second pivotal portion. A slide member is slidably inserted into the slots of the second pivotal portion and has an inclined hole in which an engaging member is engaged. The engaging member has a first end and a second end. A trace that the engaging member moves in the inclined hole constantly intersects a trace that the first end moves in the first transverse hole and a trace that the second end moves in the second transverse hole, such that the movable part is positioned by controlling the movement of the slide member.

  • Publication number: 20120086184
    Abstract: A sliding arm mechanism for attaching to an arm of a wheelchair is provided herein. One concept is directed to a sliding arm mechanism that includes a main portion and an inner cavity. The sliding arm mechanism also includes a slide rail, which is adapted to be housed within the inner cavity of the main portion. The slide rail and the main portion are slidably coupled to allow the main portion to move laterally over the slide rail in a direction parallel to the top part of the arm of the wheelchair, thus allowing the main portion to move between a first position and a second position. In some embodiments, the first position corresponds to a full-length position and the second position corresponds to a desk-length position, such that a user can adjust the sliding arm mechanism to access a desk or table.

  • Patent number: 8146999
    Abstract: An aircraft seat has an adjustable armrest in which the armrest platform is supported by a hinged attachment to an armrest support member. The hinged attachment between the armrest platform and the arm support member is located at the wrist-end of the arm support member near the aircraft control stick. The armrest platform and the armrest support are locked into position by means of telescoping struts that are controlled at the wrist-end of the arm platform member. The telescoping struts can be selectively locked to create triangular and/or quadrilateral trusses that lock the armrest firmly into position and may include springs or other elements to bias the armrest platform up and forward so that the armrest “floats” when the telescoping struts re released.
