In one embodiment, a cot loading and unloading system includes a fixed rail having a track, wherein the fixed rail is operable to be fixed to a floor, and a carriage directly coupled to the track and operable to travel along the fixed rail on the track, wherein the carriage is further operable to travel to an extended position such that at least a portion of the carriage extends beyond a length of the fixed rail.

In one embodiment, a system includes a cot loading and unloading system having a fixed rail including a track, wherein the fixed rail is operable to be fixed to a floor, a carriage having a carriage wireless chip, wherein the carriage is coupled to the track and operable to travel along the fixed rail on the track, and a master controller having a master wireless chip. The system further includes a cot having a cot wireless chip. The master wireless chip is operable to transmit a broadcast address to the cot, and the cot wireless chip is operable to receive the broadcast address and transmit a cot address signal. The carriage wireless chip is operable to receive the cot address signal and transmit a strength signal based on the cot address signal. The master controller receives the strength signal from the carriage wireless chip.

In one embodiment, a carriage of a cot loading and unloading system includes a plurality of wheels for engaging a track defined by a fixed rail of the cot loading and unloading system, a power drive assembly operable to drive the carriage to travel along the track of the fixed rail, and a pair of lift arms for supporting a cot.

In one embodiment a support beam for supporting a carriage of a cot loading and unloading system includes a support beam member operable to translate within a fixed rail that is fixed to a vehicle, and operable to support the carriage beyond a length of the fixed rail when the support beam is in an extended position.

In one embodiment, a carriage of a cot loading and unloading system, the carriage includes a plurality of wheels for engaging a track defined by a fixed rail of the cot loading and unloading system, wherein the carriage is operable to travel to an end of the fixed rail such that a portion of the carriage extends beyond a length of the track, and a pair of load arms for supporting a cot.

In one embodiment, a removable section of a fixed rail for a cot loading and unloading system, the removable section includes a first side, a second side, wherein each of the first side and the second side define a track for wheels of a carriage operable to translate on the fixed rail and the removable section, and at least one fastening mechanism for removably attaching the removable section to an end roller support section of the fixed rail.

A litter lift system includes a winch and a lifting strap. The winch includes a rotatable spool. The lifting strap has one end coupled to the rotatable spool and is movable due to rotation of the rotatable spool. The lifting strap has a first lifting segment and a second lifting segment positioned away from the end of the lifting strap coupled to the rotatable spool. The first lifting segment and the second lifting segment are each forked to interface with a frame of a litter at first lifting segment and second lifting segment distal ends, wherein a coupling is attached to the first lifting segment. Rotation of the rotatable spool in a first direction raises the first lifting segment and the second lifting segment. Rotation of the rotatable spool in a second direction different from the first direction lowers the first lifting segment and the second lifting segment.

A cot fastening system for fastening a cot to an emergency vehicle includes a frame configured for mounting to the floor of an emergency vehicle, which has a longitudinal axis and a cot loading direction along the longitudinal axis. The system includes a first restraint assembly for coupling to a first cot attachment of the cot, which is mounted to the frame. The system further includes a second restraint assembly for coupling to a second cot attachment, which is also mounted to the frame. The system further includes a spring, such as a coil spring, for biasing the cot in a direction opposed from the loading direction of the frame to thereby apply a pre-load on at least one of said restraint assemblies.

A reconfigurable compartment for a military vehicle. The reconfigurable compartment includes a floor, a front, a rear, a roof, and sides. The floor, the front, the rear, the roof, and the sides are removably coupled with each other to define the reconfigurable compartment. At least one of the floor, the front, the rear, the roof, or the sides are function-specific and replaceable with a different function-specific at least one of the floor, the front, the rear, the roof, or the sides and thereby facilitate transitioning an overall function of the military vehicle to accommodate a variety of different vehicle applications.
