With Means To Control Rearward Chair Tipping Patents (Class 297/310)
  • Patent number: 10799413
    Abstract: A restraint chair includes a supporting frame with a seat and a desk. A wrist capture bar is associated with the desk and is displaceable between a retracted position and an extended position. An ankle capture bar is associated with the desk pedestal and is displaceable between a disengaged position and an engaged position. Control levers positioned behind the seat are coupled with the wrist capture bar and the ankle capture bar via a link assembly. Translation of the control levers effects respective displacement of the wrist capture bar between the retracted position and the extended position and of the ankle capture bar between the disengaged position and the engaged position.

  • Patent number: 7914076
    Abstract: Dental devices with cylinders, trunnions, and limit switches, and a method are provided. The dental devices include a cylinder and a trunnion having a cavity and an outer surface. A portion of the cylinder is slidably mounted within the cavity of the trunnion, and a portion of the cylinder protrudes out of the trunnion. The limit switch is coupled to the outer surface of the trunnion, with the limit switch is operable to contact the cylinder. Separation of the limit switch and the cylinder causes actuation of the limit switch, and the actuation of the limit switch inhibits a downward movement of the device. Alternatively, the limit switch may be coupled to the portion of the cylinder that protrudes out of the trunnion, with the limit switch operable to contact the trunnion. As such, separation of the limit switch and the trunnion causes actuation of the limit switch.

  • Patent number: 7344155
    Abstract: A power wheelchair is provided having one or more anti-tip wheels for stabilizing the movement of the frame about the drive wheels. An anti-tip wheel is attached to the end of a suspension arm which is pivotally attached to the frame of the wheelchair. A spring resiliently supports the anti-tip wheel in a neutral position relative to the ground upon which the drive wheels of the wheelchair normal ride. A retaining system selectively fixes position of the anti-tip wheels relative to the frame. The retaining system employs a plurality of teeth, with one portion disposed in combination with said suspension arm, and at least one other tooth disposed for engaging said one portion to provide unidirectional retention of the position of said suspension arm relative to the frame. The engagement of the teeth to lock the position of the suspension arm may be responsive to the torque generated by the motor.

    Abstract: A stabilizing system for a reclinable wheelchair connects anti-tip members to the wheelchair seat such that pivoting of the seat causes pivoting of the anti-tip members. In one embodiment, the stabilizing system includes cables connected at opposite ends to the seat and to the anti-tip members. The cables may be connected to the seat bottom or, alternately, to the seat back. The anti-tip members may incorporate a pivoting suspension member that includes a drive motor for the wheelchair. Pivot control mechanisms connected to the cables can be used to permit a predetermined amount of seat pivot without corresponding pivot of the anti-tip members. The stabilizing system alternatively includes axially compressible link members connecting the seat back to the anti-tip members to provide controlled pivoting of the anti-tip members based on pivoting of the seat.

    Abstract: A simplified reclining mechanism, as for chairs and seating, is herein described. The balanced design of such a reclinable chair for yard or patio usage is herein described. The reclining mechanism is an integral part of the chair or seat. The contoured design of the seat, back, legs and headrest gives firm, comfortable support to all parts of the body in both positions. What makes this chair stand above the rest is its unique 2 position balanced design. In the upright position it functions as a chair with head and legrest. Balance is the key to this design. By slightly throwing or shifting your weight backwards, this chair teters, giving a feeling of weightlessness and falling backwards until it lands solidly on its rear legs. In this position, every part of the occupant's body is cradled by the design. This chair also has the health advantage of having your legs lifted and held at heart level.

    Abstract: The power wheelchair includes an anti-tip assembly extending from the frame. The anti-tip assembly includes a plate secured to the frame via a dampening mechanism. A first arm extends from the plate and is mounted thereto for a limited amount of relative movement. A grounding engaging wheel disposed on a distal end of the arm is urged toward the ground surface by a biasing spring interposed between the arm and the plate. As the wheelchair begins to tip, anti-tip or resistive forces are generated initially by the biasing spring. This resisting force continues in a linear fashion until relative movement between the arm and the plate ceases. Thereafter, further resistive forces are provided by the dampener as movement of the plate toward the frame is resisted in a linear fashion by the dampener.

  • Patent number: 4534591
    Abstract: Controlled rocking action furniture such as a rocking chair is formed with curved side frame pieces for rocking engagement with the ground. Each curved side frame piece comprises a major smooth curved portion in turn composed of at least three component arcs of curvature of increasing radius. A seat frame joins the curved side frame pieces and defines an operating space near the base of the furniture. An upright stop mechanism is housed in the operating space and includes extendable and retractable legs which may be extended and retracted between a position substantially within the operating space and a position extending outside the seat frame in contact with the ground for stopping the chair in upright position. The side frame pieces are formed with first and second minor reverse curved portions at each end of the major curved portion providing forward and backward rocking stops.

  • Patent number: 4227740
    Abstract: The attachment comprises two U-shaped tubular members joined at their open ends and offset from each other by an adjustable obtuse angle. Material providing a head rest is secured to one of the U-shaped members adjacent its closed end and a non-skid material is applied to the closed end of the other U-shaped member. The ends of the other U-shaped member are offset at an angle to facilitate insertion into the tubular handles of a wheelchair. With the attachment secured to the wheelchair, the chair can be tipped backwards and is supported by the closed end of the other U-shaped member. Two additional straps extend about the one U-shaped member below the head rest to support the upper back of the wheelchair occupant.

  • Patent number: 4123102
    Abstract: A rocker-type chair is used which is normally unbalanced in a rearwardly reclining direction. A rear support frame has its lower and rearward end in engagement with the floor while its upper and forward end is pivotally secured to the rearward side of the chair. The rear support frame is forcibly pivotally rotated relative to the chair in order to selectively vary the extent to which the chair reclines rearwardly.As the pivoting action takes place, the main part of the chair turns upon its rocker-like members. The lower and rearward end of the rear support frame slides or rolls horizontally along the floor surface. The weight of the occupant of the chair is at all times divided between two forward support points which are provided by the rocker-like members, and a rear support point which is provided by the rear support frame.

  • Patent number: 3945651
    Abstract: A chair includes a lower seat cushion member which is independently pivotable about a pivot on the chair frame and a rear back cushion member which is independently pivotable about a pivot on the chair frame. The rear and lower seat cushion members are not interconnected and are independently pivotable with respect to each other. The cushion members are preferably biased toward a neutral rest position with a weak biasing force so that the occupant of the chair can easily cause the cushions to pivot so as to assume the proper support position for the occupant.
