Testing
Impact Damping
This test provides a measure of how much energy is absorbed by the cushion and how much is returned to the occupant’s tissue. Designed to mimic a curb drop.
Why this test is needed
When a wheelchair drops off a curb, the energy of the impact is transferred through the cushion to the occupant.
How this test is performed
Measures either the force absorbed by the cushion or the energy returned to the occupant. Data is gathered by an accelerometer and reported in “G’s.”
