| Function |
This patent concerns improvements of a wheelchairs chassis. It is designed to allow the user to adjust the wheelchair according to his morphologie. Indeed, it has many adjustable parts. Armrests, footrest and handles are adjustable in height thank to a solution composed by a catch. The structure must resist to the stress provided by the user. However, it must be the lightest possible. So, the chassis is made with hollow tubes and the supports of the wheels are dug. Finally, the inclination of the handle is ensured by a threaded rod. Its position is held by 2 scews. |
