Abstract: The present disclosure relates to a wheelchair (1) with tilt capabilities. The electric wheelchair comprises a chassis (3), 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.

Abstract: A backrest fixation system (1) for a wheelchair, wherein the backrest fixation system (1) comprises a seat frame member (3) having a groove side (3a) provided with a first groove (5) having first groove retaining surfaces, which seat frame member (3) has a first lateral side (3b) and a second lateral side (3c) parallel to each other and which define lateral sides of the groove side (3a), a first groove insert member (9) arranged in the first groove (5) and retained in the first groove (5) by means of the first groove retaining surfaces, a backrest attachment member (15) having a first backrest attachment member through-opening (15a), a first fastener (17), and a reinforcement member (13) arranged between the backrest attachment member (15) and the groove side (3a) of the seat frame member (3), which reinforcement member (13) has a first leg (13a) and a second leg (13b), wherein the first leg (13a) extends along the first lateral side (3b) of the seat frame member (3) and the second leg (13b) extends along the
