An adjustable back support for a mobility device includes a first adjustable back support assembly including a first support member and a second support member, and a second adjustable back support assembly. The first support member is moveably connected to the second adjustable back support assembly, the first support member being configured to pivot relative to the second adjustable back support assembly relative to a first axis of rotation, and the second support member is moveably connected to the first support member, the second support member being configured to pivot relative to the first support member relative to a second axis of rotation that is not parallel to the first axis of rotation.

Adjustable back support

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 wheelchair having a lower frame with drive wheels and forwardly extending arms with casters and an upper frame with a seat and backrest. Linkage assemblies on opposing sides pivotably attach at a first end to the lower frame and at a second end to the upper frame. Power cylinders attached on opposing sides are extendable between the upper frame and the lower frame and are lockable from moving from a selected position. When unlocked, the power cylinders apply a supplemental force in association with a force applied by a user on the drive wheels for moving the upper frame relative to the lower frame guided by the linkage assembly. A method of adjusting the seat height of a wheelchair is disclosed.
