摘要:
A wheelchair chassis may include a first and second side frame positioned substantially parallel to and at a width apart from one another. The chassis may also include a first and second receiver tube positioned substantially parallel to and coupled to the first and second side frames, respectively. The chassis may additionally include a first and second extension tube telescopically engaged with the first and second receiver tubes, respectively. The chassis may further include a first and second cross member, with the first cross member pivotally coupled to the first receiver tube and the second extension tube and the second cross member pivotally coupled to the second receiver tube and the first extension tube. The second cross member may be engaged to the first cross member in an X-shaped configuration disposed horizontally between the side frames, where the second cross member is substantially co-planar with the first cross member.
