Abstract: The inventions disclosed herein relate to wheelchair anti-tippers that are adjustable. For example, adjustable wheelchair anti-tippers can allow the wheelchair pusher (e.g., caretaker) to move the anti-tippers up and down, e.g., to prevent obstruction of the walking path. The wheelchair anti-tippers disclosed herein are adjusted, e.g., by moving a lever. The wheelchair anti-tippers disclosed herein can reduce the need for a wheelchair pusher to bend over multiple times to adjust the anti-tippers, which can be ergonomically beneficial to the wheelchair pusher. If wheelchair tips there is a high chance the occupant will become injured, an anti-tipper can prevent this and assist in keeping the occupant safe.
