A wheelchair including a frame and a suspension system. The suspension system may have at least one front caster arm pivotally connected to the frame, a front caster connected to the front caster arm, a first link, and a second link. The first link is pivotally connected to the frame, and the second link is slidably connected to the front caster arm and pivotally connected to the first link.
A multi-axis headrest system for simultaneously locking or adjusting all axis of an adjustable headrest with a single lever or a single point of adjustment is provided. No external tools are required but may be used if desired. The single lever or point of adjustment allows the headrest to be correctly positioned optimizing the comfort, function and safety of the user. The single lever or point of adjustment provides the caregiver, or attending individual, the ability to adjust the positioning of the headrest with greater ease, more control and confidence. The single lever or point of adjustment causes a locking mechanism or means to generate a clamping force that locks the headrest in place. The same lever or point of adjustment also causes the locking mechanism or means to release the clamping force to allow adjustment of the headrest. The ease of adjustability is achieved without compromising security and durability.

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 wheelchair includes a chassis, a positioning module, a seat frame, and a seat. The positioning module is mounted to an upper portion of the chassis. The seat frame includes a support member secured to and spanning a seating area of the positioning module and a front frame member secured to a front end of the support member and overhanging a front edge of the seating area of the positioning module, such that the seat frame at least partially straddles the positioning module. The front frame member is connected with and at least partially supports at least one of a side frame member, foot rest, leg rest and arm rest assembled with and supported by the front frame member. The seat is secured to an upper surface of the support member.
