  • Growable wheelchair
    Patent number: 6227559
    Abstract: A wheelchair has grow-tabs that permit the width of the wheelchair to be adjusted without affecting its height. The wheelchair has a side frame and a cross-brace member. The side frame has upper and lower side rails. The cross-brace member has upper and lower ends. An upper grow-tab is connected to the upper side rail. A link is connected between the upper grow-tab and the upper end of the cross-brace member. The upper grow-tab and the link are laterally adjustable relative to one another to vary the lateral space between the upper side rail and the cross-brace member without varying the height of the upper side rail. A lower grow-tab is connected to the lower side rail. The lower grow-tab is connected to the lower end of the cross-brace member. The lower grow-tab and the lower end of the cross-brace member are laterally adjustable relative to one another to vary the lateral space between the lower side rail and the cross-brace member without varying the height of the lower side rail.
