摘要：The commonplace laterally collapsible wheelchair is rendered more convenient and versatile by the addition thereto of several add-on attachments which can be readily installed by the purchaser of the chair at minimum cost and without structural alteration of the basic wheelchair. One or more of the attachments can be sold in "do-it-yourself" kits. The attachments include a chair width adjustment, curb climbing wheels, a quick removable seat back, wheel spoke protectors and a front wheel adjuster to compensate for inclines during use of the wheelchair.
