Innovative and patented frame design
Catalyst frames are constructed from 7000 series aluminum, or Ti3AL/2.5V titanium alloy on the Catalyst 5Ti. A stronger and lighter vibration dampening alloy that contributes to the Catalyst’s superior durability and high quality construction. You can always count on quality construction when choosing a Catalyst.
Dual interlocking cross brace
The Dual Interlocking Cross Brace design creates a frame that locks together to minimise the unwanted movement, or “front to back” racking, while redistributing loads onto components that can better manage forces. What this means to you is that no matter how much you use your Catalyst, the frame will remain as solid as it was the day you got it.
Frame depth matches seat depth
Seat depth is an important function of every chair. It promotes proper seating position and can help with pressure reduction. So many manufacturers use the seat upholstery to measure the seat depth, leaving excess front frame protrusion. Ki Mobility matches the frame depth to the seat depth, on every chair. This results in a lighter chair, improved turning radius, easier transportation, storage, and a better result for the user.
Between the rails design
On typical above-the-rails designs all of the forces from the ground up, into the chair, and from the user down, through the chair, are transferred into the cross braces. In order to effectively deal with these loads other manufacturers design heavy cross-braces. The Catalyst’s unique “between-the-rails” design transfers these loads from the cross brace to the vertical side frames. The geometry of the side frames allows them to support far greater loads.
Power X hinge
The Catalyst’s patented Power X-Hinge revolutionises how the cross brace folds within the frame by acting as an extensible link that expands and contracts when the frame folds and unfolds. This patented device allows for a unique geometrical frame design that is more structurally sound than other designs while also making it much easier to fold and unfold, every single time.
Swing away front hangers
Enjoy the simplicity and strength of Catalyst’s patented swing-away footrest hangers. The most intuitive hanger on the market allows you to attach and detach from any angle by simply pulling up or pushing down. It doesn’t get any easier than this. The tapered engagement keeps the footrests snug and rattle free.
Structural integrity
Some other wheelchairs rely on the tension of the seat sling to solidify their frame when opened. However after a few months the upholstery experiences a natural stretching and your chair is “loosey goosey”. The Power X-hinge eliminates the need for the seat sling to be a structural part of your frame. A Catalyst is solid even without upholstery. This ensures a more rigid and responsive ride.
Height adjustable armrests
The tapered, noise free, no-rattle design of the height adjustable armrest produces a rock solid feel that is functional, light weight and easy to use. Like many of the options and accessories on Catalyst these were designed to be durable and user friendly. This is just one of many armrest options available through the Catalyst range.
Maxx Performance Spokes
Maxx Performance is Ki’s new spoke wheel that offers performance and style without a high price tag. It features eighteen radial spokes and a high flange hub that result in increased rigidity for a more responsive, better performing wheel. The heightened level of responsiveness combined with a lightweight design give the rider the most from every push. Constructed with a 6061 series aluminum rim and straight steel spokes with a durable black satin finish for a look and feel that is anything but standard.Technical specifications
