Telescoping tubes are added to the left and right front posts of a wheelchair for cooperation with the front post slides normally received in the front posts to permit greater telescopic extension of the slides from the front posts when the wheelchair is folded. With such arrangement, a wider seat may be applied to a conventional wheelchair, the addition of the telescoping arrangement not requiring any major alteration of the basic components making up the wheelchair. Each telescoping arrangement includes an extremely inexpensive and unique interior coupling preventing telescopic extension beyond a certain distance so that the front posts and front post slides will not become separated. |
