Abstract: A patient transport apparatus for use with a vehicle, comprising a lift mechanism between a base and a support frame to move between an extended configuration defining a first distance and a retracted configuration defining a second distance. An interface generates a user signal. A sensor generates a sensor signal corresponding to force acting on the base relative to the support frame. A controller determines if the user signal corresponds to an extend or retract command; determines if the force acting on the base has exceeded a predetermined threshold value based on the sensor signal; drives the lift mechanism toward the extended configuration where the user signal corresponds to the extend command and toward the retracted configuration where the user signal corresponds to the retract command; and interrupts driving the lift mechanism to stop motion of the lift mechanism in response to the sensor signal exceeding the predetermined threshold value.

Abstract: A patient support apparatus supports a patient and includes a litter. A base is disposed below the litter. A lift mechanism is configured to move the litter and the base relative to one another between extended and collapsed positions. The lift mechanism includes first and second frame assemblies each including an outer frame member and an inner frame member arranged to move within the outer frame member. First and second rollers and first and second slide members are disposed between the outer and inner frame members. The first and second rollers are arranged to roll along at least one of the outer and inner frame members with a load exerted on the lift mechanism from the litter. The first and second slide members are arranged to slide along at least one of the outer and inner frame members with a load exerted on the lift mechanism from the base.

Abstract: An emergency cot includes a litter frame, a base, and a lift assembly supporting the litter frame relative to the base. The lift assembly includes load bearing members pivotally coupled to the litter frame by head-end upper pivot connections and foot-end upper pivot connections and to the base by head-end lower pivot connections and foot-end lower pivot connections for raising or lowering the base or the litter frame with respect to the other. The foot-end upper pivot connections or head-end upper pivot connections are movable toward or away from the longitudinal axis of the litter frame to allow one end of the litter frame to be tilted upwardly.
