A reversible seating mechanism includes a frame and a cross member pivotally supported on the frame for rotational movement in a plane generally parallel to the frame to define a tilt angle. A mounting plate is pivotally supported on the cross member for rotational movement in a plane generally parallel to the cross member to define one of a forward and rearward facing orientation. The mounting plate is moveable on the cross member to be oriented to the tilt angle. A tilt limiter restricts movement of the mounting plate between the forward and rearward facing orientations until the tilt angle is adjusted to a preset angle. The tilt limiter limits a forward facing tilt angle to an angle less than a rearward tilt angle.

A transportation device and automatic tilt stabilizer are disclosed herein. The transportation device has a structure with wheels joined by a shaft to a platform or chassis configured to support a basket, a mat, a seat and/or a tray. The automatic tilt stabilizer is configured to automatically stabilize the inclination of the platform or chassis, and includes a tilt sensor configured to detect an inclination of the platform or chassis, and a motor activated by a microcontroller, configured to correct the inclination of the platform or chassis, so that the platform or chassis returns to a predefined inclination.

A self-balancing vehicle comprising two axially spaced wheels (3, 4) mounted on a main body (2), an electric drive coupled to at least one wheel (3, 4), control means adapted to maintain the vehicle in balance by controlling the drive, a receptable for carrying and conveying a load, the vehicle having an adjustment mechanism (7) for linear displacement of the receptable arranged so that the receptable is adjustable by the linear displacement both along the longitudinal axis and along the vertical axis of the vehicle.

A medical chair includes a base, a seat, and a leg rest pivotally mounted relative to the seat and adapted to move between an extended position and a retracted position. The chair further includes a first actuator for tilting the seat with respect to the base, a second actuator for lifting the seat with respect to the base, and a leg rest actuator adapted to move the leg rest. The chair also includes a controller adapted to control the first and second actuators to move the seat between a first position and a second position such that the seat is both lifted and tilted at the same time as the seat moves from the first position to the second position, and wherein the controller is adapted to control the leg rest actuator such that the leg rest maintains a substantially constant orientation with respect to the floor.

A surgical table includes a mechanism for causing movement of a tabletop of the table relative to a column of the table in a selected longitudinal or transverse direction of the tabletop, the mechanism including first and second drive elements movably mounted on one of the column and the tabletop and a traverse device mounted on the other of the column and the tabletop, wherein the tabletop is movable relative to the column between a predetermined traverse position, at which both of the first and second drive elements are engaged with the traverse device, and a first traverse position, at which the first drive element is engaged with the traverse device and the second drive element is disengaged from the traverse device. Also described is a system for helping a user dispose a tabletop of a table a predetermined position relative to a column of the table.

An adjustable chair includes upper and lower base members, a seat assembly secured to the upper base member, and a chair adjusting mechanism. In an embodiment the upper base member is connected to the lower base member by first and second linking members each having a first end connected to the lower base member and a second end slideably received in corresponding first and second arcuate tracks disposed in the upper base member, such that movement of the second ends into and out of the tracks results in vertical movement of the seat assembly relative to the base. In a further embodiment the seat bottom and seat base comprise cooperating arcuate rails, tracks, and/or bearing members, where cooperative action of the arcuate rails, tracks, and/or bearing members enables the seat bottom to tilt relative to the seat base. In a further embodiment the seat bottom and seat back comprise cooperating arcuate rails, tracks, and/or bearing members, where cooperative action of the arcuate rails, tracks, and/or bearing members enables the seat back to recline relative to the seat bottom.

A seat positioning system includes a base frame having a pair of forward slots and a pair of rear slots, and a seat frame having a front end and a back end. The seat frame is coupled to the base frame and movable relative to the base frame. A first pair of linkages is slideably coupled to the pair of forward slots and connects the frames. A first pair of locking devices has a locked configuration adapted to prevent the first pair of linkages from sliding relative to the pair of forward slots and an unlocked configuration adapted to allow the first pair of linkages to slide relative to the pair of forward slots. A second pair of linkages slideably is coupled to the pair of rear slots and connects the frames. An actuator is pivotally connected to both the seat frame and the base frame and is configured to extend and contract to move the seat frame relative to the base frame.

The present discloses a mid-wheel tilt-in-space manual wheelchair with a constant shoulder position. The tilting wheelchair comprises an upper section, a lower section and a tilting mechanism. The upper section comprises an upper frame defining a user's seat, a back post and an armrest. The lower section comprises a lower frame, two drive wheels and at least two guiding wheels, preferably, two rear casters and two front casters. The two drive wheels being positioned on the lower frame and have a same rotation axis. The tilting mechanism is being adapted to rotatably engage the upper section to the lower section in such a way that the pivot center of the upper section is being coincident at any moment and any position with the rotation axis of the drive wheels allowing to maintain a constant distance between a user's shoulder and each pushrim of each drive wheel.

The collapsible lovemaking apparatus has an elongated housing having opposing ends. A floor, a top platform, opposing sidewalls, and a rigidly fixed end wall having a handle form the housing and define a hollow interior. A chair platform is slidably mounted on telescoping tubes attached to the floor, the platform being slidable out of the open housing end and supported at one end by wheels. An adjustable height pedestal chair is mounted on the platform, the chair back being rotatable 180 to define an end wall closing the open end of the housing. A second chair seat having a reclining chair back is mounted on a trolley on the top platform facing the adjustable height chair, the reclining back being collapsible to a flat position. The pedestal chair and the trolley-mounted chair seat may roll towards and away from each other to facilitate love making.

A surgical table includes a mechanism for causing movement of a tabletop of the table relative to a column of the table in a selected longitudinal or transverse direction of the tabletop, the mechanism including first and second drive elements movably mounted on one of the column and the tabletop and a traverse device mounted on the other of the column and the tabletop, wherein the tabletop is movable relative to the column between a predetermined traverse position, at which both of the first and second drive elements are engaged with the traverse device, and a first traverse position, at which the first drive element is engaged with the traverse device and the second drive element is disengaged from the traverse device. Also described is a system for helping a user dispose a tabletop of a table a predetermined position relative to a column of the table.
