The present disclosure relates to a wheelchair () with tilt capabilities. The electric wheelchair comprises a chassis (), a lift device having a base member which is fixedly arranged to the chassis, and a lifting member arranged to move rectilinearly relative to the base member along an axis defined by a longitudinal extension of the lifting member, a tilt frame, a first arm pivotally coupled to the lifting member and the tilt frame, and a second arm coupled to the base member, and which second arm is pivotally coupled to the first arm forming a pivot connection, wherein movement of the lifting member towards the extended position moves the pivot connection towards the base member and movement of the lifting member towards the retracted position moves the pivot connection away from the base member.

Wheelchair with tilt capability

A seat assembly including a seat, a support plate configured to pivot with respect to the seat, a slide plate slidably mounted to the support plate, and a pivot arm positioned between the support plate and the slide plate and connected to the slide plate and the seat. When the support plate is pivotally adjusted with respect to the seat, the pivot arm causes the slide plate to slide along the support plate.

Wheelchair backrest assembly

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.

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.

Wheelchair legrest assembly

A powered wheelchair includes a seat assembly configured to support an individual, a curved 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 curved legrest assembly to be separately and independently adjusted with respect to one another.

A seat, for example, a wheelchair, comprises a seat part, a backrest part, armrests, and footrests. The seat part and the backrest part have a commonly adjustable width, e.g. the side support portions can essentially be inserted into portions of a central frame part, and transversal bars in the backrest have adjustable widths. The seat part also has adjustable front and rear edges, obtained by adjusting adjustable front and rear support portions. The inclination of the backrest is adjusted by clamping screws mounted in side plate portions provided with slots. The height of the backrest can also be adjusted by displacing an upper portion thereof. The inclination of the footrests is varied by moving hinges having a large frictional force normally holding them stationary.

Multipositioning system seat

A foot rest arrangement for wheelchairs includes a telescopic strut structure with an outer (B) and an inner strut (C) axially displaceable inside the outer strut, and a foot rest (A) attached to the free lower end (at 0) of one strut (B) while the opposing free upper end of the other strut (C) is attached to the wheelchair frame or to the forward portion of the chair seat frame, so that the strut structure carries the foot rest at a distance from the chair seat (6), this distance being variable by raising and lowering the foot rest and/or chair seat. Latching means (H,R) are also arranged to lock the struts relative each other, with the foot rest at a given distance from the chair seat. A suitable illustration is FIG. 1.

Foot rest arrangement for wheelchairs

A manoeuverable, motor-driven wheeled chassis includes a chassis structure carrying two pairs of support wheels (N.sub.1, M.sub.1) separated in the longitudinal direction of the chassis. Between the pairs of support wheels there is a pair of drive wheels (L.sub.1). The chassis structure includes a first frame structure (P.sub.1, 14) carrying a first pair of support wheels (N.sub.1) and the pair of drive wheels (L.sub.1), and a second frame structure (O.sub.1, 10) carrying the second pair of support wheels (M.sub.1) and vertically pivotably connected to the first frame structure (at K). The wheeled chassis is primarily intended for use as a wheelchair (2,4,6).
