Abstract
The present disclosure relates to a tilt assembly (1) for a powered wheelchair (15), comprising: an elongated base member (3) provided with an axial channel, a lifting member (5) configured to be received by the base member (3) and to move rectilinearly in the channel, between a retracted position and an extended position relative to the base member (3), a tilt frame (7) pivotally connected to the lifting member (5), the tilt frame (7) being configured for mounting a seat assembly (21) thereto, and an arm (9) pivotally connected to the base member (5) and to the tilt frame (7), wherein the tilt frame (7) is configured to obtain a perpendicular orientation relative to a central axis (11) of the lifting member (5) when the lifting member (5) is in the retracted position and to be inclined relative to the central axis (11) when the lifting member (5) is in the extended position, to thereby provide a tilt functionality.
