Quickie S-626: Lower Seat Height

The purple sub-frame between the seat and the main frame had to go. This also eliminated what the leg hangers attached to…but no loss. I was going to get rid of those nasty contraptions anyway. When Quickie engineers die and go to Hell, they'll have to ride around in chairs equipped with those leg hangers.

To mount the seat I made a simple U-shaped bracket from aluminum. At the same time I positioned the seat rearward another three inches. This greatly improved the balance by unloading the front casters even more. There are a couple side advantages too. The chair gets easier to steer in tight quarters because the front casters aren't doing so much of the turning and the battery range improves …for the same reason. Any extra torque the motors must generate eats into the battery's amp-hour capacity. Dragging heavily loaded casters sideways while turning eats a lot of amps. This applies to the constant contact rear anti-tippers also.

Seat dump (how much lower the rear of a seat is compared to the front) could be made adjustable but on the bracket you see here the dump is set. If the seat seems very flat to you in the previous pictures, remember that this chair has suspension that increases seat dump as weight is applied to the seat. The suspension compresses about one inch when I transfer my 120 pounds to the chair.
