Abstract: A backrest assembly for a wheelchair includes a support plate pivotally connected to a seat, wherein the support plate is configured to be pivotally adjusted between upright and reclined positions with respect to the seat; a slide plate slidably secured on a front surface of the support plate; and a backrest adjustment assembly operatively connected to the support plate and the slide plate. The backrest adjustment assembly includes a link configured to adjust the support plate. The slide plate slides over the support plate through the link.

Abstract: A powered wheelchair includes a seat assembly configured to support an individual, a legrest assembly pivotally connected to the seat assembly, and an adjustment assembly including an actuator operatively connected to the central column through a piston slidably secured within a sleeve. The adjustment assembly is secured underneath the seat assembly. The powered wheelchair may also include an extension bracket that allows legrests and a central column of the legrest assembly to be separately and independently adjusted with respect to one another.

Abstract: A wheelchair of the mid-wheel drive type comprises a chassis frame (10), a pair of front link arms (30) and a pair of rear link arms. The link arms are pivotally connected to the chassis frame. Front caster wheels (32) and drive wheels (53) are fixed to the front link arms. Rear caster wheels (42) are fixed to the rear link arms. Each front link arm (30) is operatively connected to an adjacent rear link arm (40) by means of a respective coupling means (70), which is arranged to transmit pivotal movement of one of the front (30) and rear (40) link arm to an opposite pivotal movement of the other of the front (30) and rear (40) link arm.
