A recreational vehicle having an extendable slide-out controlled by an actuator assembly is provided with a damage avoidance system. The damage avoidance system determines if the slide-out is in an adverse state and, if the adverse state is detected, inhibits the actuator assembly from moving the slide-out. The slide-out is in the adverse state if (a) a collision between the slide-out and a nearby object is imminent, (b) a collision has recently occurred, or (c) a resistive force is acting on the slide-out which substantially inhibits the actuator assembly from moving the slide-out. The damage avoidance system comprises a sensor module for monitoring the state of the slide-out and for providing an override signal to the actuator assembly, wherein the override signal is indicative of the slide-out being in the adverse state. In one embodiment, the sensor module comprises a position sensor disposed adjacent an interior swivel chair of the recreational vehicle, wherein the sensor module generates the override signal if the position sensor detects that the chair is not facing forward. In another embodiment, the sensor module comprises a shock sensor coupled to the slide-out. In yet another embodiment, the sensor module comprises a load sensor that monitors the mechanical load imposed on the actuator assembly.

Multi-chamber turns can be used with each section having independently controlled pressurized gas. mposition wherein said gas generator fluidly communicates with said actuator upon pretensioner activation. 4. The pretensioner of claim 1 wherein said actuator comprises a first component and a second component interlocked with said first component, the second component forming a leading edge of the actuator and having a first flat side and a second flat side wherein the sides are joined by a rounded edge, the rounded edge oriented to be in flush communication with the strap during pretensioner activation. 5. A pretensioner cooperating with a webbing reel shaft axially extending from a seatbelt retractor webbing reel, that upon activation pretensions seatbelt webbing wound about the reel, the pretensioner comprising: a housing containing a first rectangular passage longitudinally extending within said housing, the passage having a first end and a second end, and, the housing further containing a first end of the webbing reel shaft; a first clutch segment and a second clutch segment fixed and spaced radially outwardly of said first end of said retractor shaft prior to pretensioner activation, each segment in circumferential opposition to the other segment wherein said shaft rotates independently of said segments prior to pretensioner activation and said segments grip said shaft upon pretensioner activation; a geared clutch sleeve fixed radially outwardly of the segments, said sleeve having an inner surface in flush communication with the periphery of said first and second segments wherein said clutch sleeve exerts compressive and rotary torque upon the segments upon pretensioner activation; a geared pulley in geared engagement with said clutch sleeve wherein said pulley exerts a rotary torque upon said clutch sleeve upon pretensioner activation; a strap comprising a first end fixed to said housing, an intermediate portion extending from said first end and across said first passage, and a second end extending from said intermediate portion and spooled about and fixed to said pulley wherein said strap exerts a rotary torque upon said pulley upon pretensioner activation; an actuator positioned within the first end of said passage for tensioning the strap upon pretensioner activation and thereby exerting a torque on the pulley; and a means for activating the pretensioner and driving the actuator through the passage thereby tensioning the strap, whereby upon activation of the pretensioner, the strap translates linear motion of the actuator to rotary movement of the pulley, the clutch sleeve, the clutch segments, and the spool in coaxial communication with the clutch sleeve, and thereby pretensions the seatbelt. 6. A pretensioner cooperating with a webbing reel shaft axially extending from a seatbelt retractor webbing reel, that upon activation pretensions seatbelt webbing wound about the reel, the pretensioner comprising: a housing containing a first rectangular passage longitudinally extending within said housing, the passage having a first end and a second end, and, the housing further containing a first end of the webbing reel shaft; a geared clutch spaced radially outwardly of said first end of the shaft for gripping the shaft upon pretensioner activation; a geared pulley in geared engagement with said clutch wherein said pulley exerts a rotary torque upon said clutch upon pretensioner activation; a strap comprising a first end fixed to said housing, an intermediate portion extending from said first end and across said first passage, and a second end extending from said intermediate portion and spooled about and fixed to said pulley wherein said strap exerts a rotary torque upon said pulley upon pretensioner activation; an actuator positioned within the first end of said passage for tensioning the strap upon pretensioner activation and thereby exerting a torque on the pulley; and a means for activating the pretensioner and driving the actuator through the passage thereby tensioning the strap, whereby upon ac
