To expand on the above response, as linked to the SuperMAN site, SuperMAN stands for SUPERmarkets Meet Accessibility Needs.
On the 11th of February 2005 in France a law was passed on equal rights and opportunities, participation and citizenship of disabled. This law stated that the principle of accessibility is general regardless of the type of disability and that in 2015 in France all public places must be accessible.
The S3A pictogram, created by the French association Unapei (national union of associations for parents and friends of people with mental disabilities) is the symbol of Welcome, Support and Accessibility.
As there is an international symbol which indicates those places that are accessible to people with limited mobility, S3A pictogram has been created in order to easily localize places, services and products accessible to people with mental disabilities.
For Unapei, the display of the S3A pictogram means undertaking tangible actions in favour of the accessibility and:
- making an effort for everyone’s citizenship
- being pioneers in the implementation of the French law
- being able to adapt to the needs of people with mental disabilities, in order to offer them the right support
- more in general, helping people with understanding, communication and time-and-space orientation difficulties.
Unapei prepared the Practical guide on accessibility which outlines the actions to implement in order to make the access to places, services and products easier for people with mental disabilities and therefore to be entitled to display S3A pictogram.
The seat is reserved for people with disabilities. The images are designed to show:
In general I noticed that exactly how different disabilities are shown changes and there isn’t much of a standard. You can view some more examples at: https://oae.stanford.edu/resources-faqs/disability-access-symbols
