Wheelchair manoeuvring through a passage doorway

These plots, showing the manouevring of 6 fictitious wheelchairs through a doorway, illustrate the significant influence of shape and drive wheel type on the manouevring space required for negotiation of doorways.

All wheelchairs perform a clockwise turn through the doorway. The shape of each wheelchair is shown alongside each plot.

Plot 3

Rear-wheel drive wheelchair.

This is a variation of the previous manoeuvre. Compared with the previous manouevre, the initial anti-clockwise rotation is commenced earlier, resulting in less space being required alongside the "top" door jamb.

Plot 5

Front-wheel drive wheelchair

Plot 7

This plot shows the difference between the manouevring areas of the different wheelchairs and highlights the spatial implications of shape and drive-wheel type, i.e. the effect of radial parameters.
