A recently granted patent (Publication Number: US11925589B2) discloses a litter lift system designed for vehicles, comprising a winch system with a rotatable spool and a lifting strap with two lifting segments. The system allows for the vertical adjustment of the lifting segments by winding or unwinding the strap around the spool, with the first and second lifting segments each forked to define two separate lifting loops. Additionally, the system includes rollers for suspending the lifting segments, with the spool being driven by an electric motor controlled by a controller to adjust the vertical position of the segments equally.

In the vehicle context, the litter lift system is integrated into the passenger compartment, with the winch system coupled to the roof and the lifting strap extending parallel to the roof. The system allows for the efficient lifting of a litter within the vehicle, with the lifting segments extending through a ceiling panel into the passenger compartment. The patent also details the inclusion of magnetic couplings for secure attachment and the ability to adjust the vertical position of the lifting segments independently. Furthermore, the patent describes a litter support system with rotatable parallel channels that can be deployed to lift the litter away from the frame, providing versatility in the configuration of the vehicle's interior space.
