Electric wheelchair for easy access to toilet with a lifting device for elder or people with physical disabilities

Sammanfattning: This project has been created to help elder or people with physical disabilities. The help consists on getting easier the access to the WC. To reach our purpose, we realized a really innovative idea. Our idea is based on an slim electric wheelchair with a lifting device which helps to stand up/sit. This lifting device consist in a pneumatic piston that acts only when the person wants to sit down on the toilet, pushing the chair down, or when the user wants to get up from the toilet, pushing the chair up, always keeping the back upright. This wheelchair is designed to be significantly lighter than conventional ones and very comfortable to be used indoor. A CAD model was developed to make this design and also evaluate its resistance and safety.
