Abstract
Abstract The flexible patient supporting sling of an invalid lift and transport device is equipped with a safety strap attachment having a separable buckle. A lower section of the safety strap attachment is permanently stitched to the sling near the forward edge of the sling and a suspension loop on the upper section of the safety strap engages the overhead sling hanger carried by the lift. The attachment makes the sling more secure, prevents the patient from falling out of the front of the sling during transport and suspends the patient safely in the event that the sling suspension hooks at the front of the sling become disconnected.
