  • Publication number: 20230190547
    Abstract: An alignment system for a wheelchair based steering column includes a fork assembly configured to carry a front wheel, a bearing coupled to the fork assembly, a tube member that receives the bearing and a portion of the fork assembly, a cam defining sloped cam surface leading to a recess, the cam positioned in the tube member, a biasing member configured to apply a restoring force onto the cam, the biasing member positioned in the tube member, and a steering device coupled to the fork assembly. In response to applying a rotational force to the steering device, the fork assembly rotates, responsively rotating the front wheel and sliding the bearing along the cam surface away from the recess, the cam responsively linearly translates relative to the fork assembly overcoming the restoring force.
