DESCRIPTION
The Catalyst 4C is the unquestioned performance leaders in the K4 class. The Ki Mobility Catalyst 4C utilizes an offset axle plate that offers rear seat height adjustability. Even though this is a K0004, it uses the same frame construction as the Catalyst 5 to provide superior performance and with spoke wheels the chair weighs only 24 pounds!
The Catalyst Difference |
|
| Between-the-Rails Seat Frame is Ki | Dual Interlocking Cross Braces are Ki |
 Most wheelchair seat rails sit above the frame unsupported. A between-the-rails frame design uses the side frame to improve support for the cross brace. The steel reinforced, composite seat hooks mount on the front and back of each side of the frame. These hooks have subtle edges that hold and support the seat tubes and take much of the load off of the cross braces. |
 Dual Interlocking Cross Braces have multiple advantages. The four interlocking crosstubes:
|
| Heat Treatment is Ki Ki Mobility is the only major wheelchair manufacturer to Heat Treat their wheelchair frames after welding. The heat generated during welding weakens the tubing area adjacent to the weld. This area is referred to as the Heat Affected Zone. Ki Mobilitys heat-treatment after welding significantly increases the strength and durability of the frame components. |

 Between-the-Rails Welded Lower Tabs |
Traditionally, cross braces have been engineered to form a parallelogram. This geometry was required to allow the cross brace to fold. It also forces compromises. Cross braces unsupported by the frame can be racked and are vulnerable to breakage unless reinforced. Reinforcement usually means a much heavier chair. The construction of other between-the-rails design (with welded lower tabs) adds weight, cost and restricts the ability to fold up the chair. |
 Standard Cross Brace |
|
| The Power X-Hinge eliminates the requirement that folding chairs must use a parallelogram cross brace configuration. The Power X-Hinge is an extensible link that expands and contracts when the frame folds and unfolds. This construction provides you with a frame that is:
|
|
| Seat Upholstery The Catalyst does not depend on the tautness of the seat upholstery to create a rigid frame. Traditionally, wheelchair seat upholstery gets tighter and tighter as the chair opens, until it finally snaps into place, as the linkage goes "over center". This indicates that:
