摘要： A foldable wheelchair having side frames arranged on both sides of the wheelchair, a cross-strut assembly and seat tubes for receiving a seat cover, wherein the cross-strut assembly is mounted, in regions remote from the seat tube, about parallel pivot axes in the side frame, and the axis of rotation of the struts of the cross-strut assembly is arranged parallel to the pivot axes of the cross-strut assembly, and the cross-strut assembly is connected to the seat tubes, which, in the unfolded position of the wheelchair, are received by seat tube bearings of the side frames, wherein the wheelchair has guide levers on both sides, and the respective guide lever is mounted, in a first region, in a strut of the cross-strut assembly, in a region of the cross-strut assembly between the axis of rotation of the struts of the cross-strut assembly and the seat tube, and this guide lever is mounted at a distance therefrom, in a second region, in the side frame assigned to the seat tube so as to be pivotable about a pivot axis, wherein this pivot axis is arranged parallel to the pivot axes of the cross-strut assembly in the side frames. The guide lever has a guide slot in its first region, and a guide pin, which engages in the guide slot, is connected to the strut assigned to the guide lever, and a cam is connected to the strut, and a cam follower is connected to the guide lever in its first region, wherein the cam and the cam follower interact in an end phase of the unfolding process of the wheelchair for the purpose of displacing the guide pin into a defined position in the guide slot.

摘要： A front wheel and a rear wheel are to be provided at a grounding frame. A body frame is mounted on the grounding frame and includes a mount at which a seat is to be provided. A relative position between the grounding frame and the body frame in a height direction of a wheelchair is changed via a height adjustment mechanism. The height adjustment mechanism includes an adjustment pole, a pole reception, and a holding portion. The adjustment pole extends along the height direction and is mounted on one of the body frame and the grounding frame. The pole reception is mounted on another of the body frame and the grounding frame and is engaged with the adjustment pole slidably in the height direction. The holding portion is to hold not to relatively move the adjustment pole with respect to the pole reception.

摘要： A powered wheelchair 100 with a tilt mechanism having multiple pivots that allows the wheelchair 100 to be driven and steered with or without the use of hands. The wheelchair 100 has two spaced apart drive wheels 101, each mounted to a separate shaft 104 that is independent of the other drive wheel. A drive controller drivingly coupled to the shafts 104 and the drive controller is housed within a base 102 that is pivotally situated on the shafts 104. A seat 103 mounted on a tilt mechanism enables the seat to tilt in a forward, backward, left and right direction as a result of the user displacing their body weight in either of those directions. The tilt mechanism includes three pivots, a primary pivot P1, secondary pivot P2 and tertiary pivot P3. The primary pivot P1 pivotally connects the base 102 to the shafts 104. The secondary pivot P2 is situated above and adjacent the base 102 so that the respective ends of the rod 105 are pivotally connected to the base 102.

摘要： A seat assembly for wheelchair of the type having a structure expandable from a contracted condition to an expanded position comprises a pair of tubular members connected to the structure. Each tubular member has a main tubular body, a secondary tubular body parallel to and inside the main tubular body, and an elongated slit extending along both the main tubular body and the secondary tubular body and common to both the main tubular body and the secondary tubular body. The slits open into an inner channel of the secondary tubular body. The main tubular body and the secondary tubular body form a hollow integral piece of composite material. A panel, e.g., of non-rigid material has rods on its opposite edges, the rods having a diameter smaller than that of the secondary tube and larger than a width of the slit to be held captive in the secondary tube, whereby the panel extends through the slit.

摘要： An adjustable wheelchair is disclosed which adjusts to changes in a user's size and weight which includes a scissor-type foldable mechanism which connects two side frames. Wheels for the wheelchair are attached to each of the side frames. An adjustable seat and adjustable back support are a flexible material which span from one side frame to the other. These are designed to unroll and lengthen or roll up and shorten the width of the seat and the back support between the side frames. The scissor-type foldable mechanism includes a tube which slides within a tube, a threaded rod and a threaded stop which function to allow pre-adjustment of the width of the foldable mechanism such that it may be folded and opened to the pre-adjusted width. The frames may be supplemented with reinforcements to accommodate a change in the user's weight.

摘要： A seat assembly includes a seat frame, a back frame 320 defining a back plane pivotally connected to the seat frame at a pivot joint, a back support 310 slideably secured to the back frame, and a back support adjusting mechanism. The back support adjusting mechanism includes a first linking member 355 coupling the back support to the seat frame and pivotable about the pivot axis, and a first slide member 351 slideably supported by the back frame and operatively connected to the first linking member. A second slide member 354a is affixed to the back support and slideably supported by the back frame. A second linking member 352 operatively connects the first and second slide members. Pivoting movement of the back frame from the upright position to the reclined position slides the first slide member away from the pivot axis, causing the second linking member to slide the back support toward the pivot axis.

摘要： An exemplary wheelchair comprises a main frame and a seat frame. Drive wheels and pivoting caster wheels are affixed to and support the main frame. The seat frame is connected to the main frame via left and right rear linkage arms, each rear linkage arm having a first end pivotally connected to the main frame and a second end pivotally connected to the seat frame, thereby allowing the seat frame to pivot relative to the main frame around a virtual pivot point. A seat plate having right, left, front, and rear sides is supported by the seat frame. A backrest frame is also connected to the seat frame. Left and right guide slots of the seat frame receive left and right guide rollers rotationally arranged at each end of a laterally oriented shaft connected to the main frame. The rear linkage arms and guide slots are configured so the virtual pivot point of the seat frame moves rearward when the seat frame is moved from an upright position to a tilted position.
