1. A vehicle safety system for impeding the egress of an occupant of a vehicle, the safety system comprising:
- a first safety barrier mounted to a vehicle having a cab with an open exit, the open exit extending generally from a bottom region of the cab to a top of the vehicle, the first safety barrier comprising;
a first stowed position wherein the open exit of the vehicle is substantially uncovered by the first safety barrier such that an occupant of the vehicle may egress through the exit substantially unimpeded by the first safety barrier,a first deployed position wherein the first safety barrier covers at least a portion of the open exit in order to impede the occupant'"'"'s egress through the exita control system; and
a reactive safety barrier mounted to the vehicle, the reactive barrier comprisinga second stowed position that leaves the exit of the vehicle substantially uncovered by the reactive barrier anda second deployed position that covers at least a portion of the exit in order to impede the occupant'"'"'s egress through the exit,wherein the control system deploys the reactive barrier from the second stowed position to the second deployed position in response to the occurrence of a defined event.

10. A vehicle safety system comprising:
-
a vehicle comprising a cab having an open exit generally defined by a top member connected to a pair of spaced apart side members, the open exit extending generally from the top member to a bottom region of the cab, a first safety barrier mounted to the exit, the barrier comprising a first stowed position wherein the exit of the vehicle is substantially uncovered such that an occupant of the vehicle may egress through the exit substantially unimpeded by any structure, and a first deployed position wherein the first safety barrier covers at least a portion of the exit in order to impede the occupant'"'"'s egress through the exit a motor mounted to the vehicle and configured to move the safety barrier between the first stowed position and the first deployed position, a retractor mounted to the vehicle and configured to move the safety barrier between the first stowed position and the first deployed position, and a control system configured to command the movement of the safety barrier between the first stowed position and the first deployed position in response to the occurrence of a defined event. - View Dependent Claims (11)

12. A vehicle safety system comprising:
-
a vehicle comprising an open exit generally defined by a top member connected to a pair of spaced apart side members, the open exit extending generally from the top member to a bottom of the vehicle, a safety barrier mounted to the exit, the safety barrier comprising one or more generally horizontal bladders, one or more generally vertical bladders, a stowed position wherein the horizontal and vertical bladders are substantially devoid of fluid so that the exit of the vehicle is substantially uncovered such that an occupant of the vehicle may egress through the exit substantially unimpeded any structure, and a deployed position wherein the horizontal and vertical bladders are substantially full of fluid so that the safety barrier covers at least a portion of the exit in order to impede the occupant'"'"'s egress through the exit, and a control system configured to move the safety barrier from the stowed position to the deployed position upon the occurrence of a defined event.
