WHEELCHAIR WITH TILT CAPABILITY

摘要

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.

主权项

1. An electric wheelchair (1) comprising:
a chassis (3), a lift device (11) having a base member (11a) which is fixedly arranged to the chassis (3), and a lifting member (11b) arranged to move rectilinearly relative to the base member (11a) along an axis (11c) defined by a longitudinal extension of the lifting member (11b), wherein the lifting member (11b) is arranged to move between a retracted position and an extended position, a tilt frame (17; 17′), a first arm (13; 13′) pivotally coupled to the lifting member (11b) and the tilt frame (17; 17′), and a second arm (15; 15′; 15″) coupled to the base member (11a), and which second arm (15; 15′; 15″) is pivotally coupled to the first arm (13) forming a pivot connection, wherein movement of the lifting member (11b) towards the extended position moves the pivot connection towards the base member (11a) and movement of the lifting member (11b) towards the retracted position moves the pivot connection away from the base member (11a).
