    摘要: A wheelchair including a pair of frames located on opposite sides of the wheelchair, each frame being provided with a drive wheel equipped with a hand ring, and a castor; a back rest and a leg rest each formed of a web of flexible material connecting the pair of frames together; yoke members pivotally connected at lower ends to base tubular members of the pair of frames and connected for relative pivotal movements at an intersection while being connected at upper ends to a pair of seat tubular members; a seat formed of a web of flexible material hung between the seat tubular members which are adapted to be maintained at opposite ends in pressing engagement with front post members and rear post members of the pair of frames which are kept in a spaced-apart condition to bring the back rest and leg rest to a taut condition, whereby the back rest, leg rest and seat can have their lengths adjusted to thereby adjust the width of the wheelchair to a desired value.
