A backrest support assembly 1 for supporting, in use, the backrest of a wheelchair, e.g. when the wheelchair is supported on a wheelchair tilting platform [see Fig. 4], comprises a backrest support 8 adjustably mounted on a stem 10 for height adjustment and/or angular adjustment relative to the stem. The backrest support 8 may be mounted on the stem 10 by a friction locking means, preferably a self-locking friction sleeve to allow continuous height adjustment. The backrest support 8 for the wheelchair backrest may rotate about the axis of the stem , preferably an axis transverse to the stem. An adjustable headrest 22 may be pivotally fitted to the stem 10 of the assembly. The stem 10 of the support assembly may be pivotally coupled to a base, e.g. a back wall of a tilting platform used to tilt a wheelchair. Also disclosed is a backrest support assembly for supporting a wheelchair backrest wherein a backrest support is mounted to a stem by a friction locking sleeve. A further assembly is disclosed in which the stem of the backrest support assembly is pivotally mounted to a base to allow it to be rotated about a horizontal axis. |
