Abstract

A vehicle safety system for impeding an occupant'"'"'s egress from a vehicle is provided. A barrier is deployed, either manually or automatically, to cover at least a portion of the vehicle'"'"'s exit in order to impede an occupant from egressing through the exit. The barrier may be a passive barrier or a reactive barrier. The barrier may also be a combination of a passive and a reactive barrier or the combination of several reactive barriers.

Claims

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 exit

a control system; and

a reactive safety barrier mounted to the vehicle, the reactive barrier comprising

a second stowed position that leaves the exit of the vehicle substantially uncovered by the reactive barrier and

a 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.

2. The vehicle safety system of claim 1, wherein the reactive barrier comprises an inflatable barrier.

3. The vehicle safety system of claim 2, wherein the inflatable barrier comprises a curtain.

4. A vehicle safety system for impeding the egress of an occupant of a vehicle, the safety system comprising:

a 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 barrier comprising;

a stowed position wherein the open exit of the vehicle is substantially uncovered by the safety barrier such that an occupant of the vehicle may egress through the exit substantially unimpeded by the safety barrier; and

a deployed position wherein the safety barrier covers at least a portion of the open exit in order to impede the occupant'"'"'s egress through the exit; and

a control system,

wherein the control system deploys the safety barrier from the stowed position to the deployed position in response to the occurrence of a defined event.

5. The vehicle safety system of claim 4, wherein the safety barrier comprises an inflatable barrier.

6. The vehicle safety system of claim 5, wherein the inflatable barrier comprises a curtain.

7. The vehicle safety system of claim 5, further comprising an inflator in fluid communication with the barrier, and wherein the control system signals the inflator to inject fluid into the barrier in order to move the inflatable barrier from the stowed position to the deployed position upon the occurrence of the defined event.

8. The vehicle safety system of claim 7, wherein the control system comprises one or more sensors configured to detect the defined event.

9. The vehicle safety system of claim 8, wherein the one or more sensors comprises a roll sensor.

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.

11. The vehicle safety system of claim 10 further comprising:

a second safety barrier mounted to the exit, the second safety barrier comprising

a second stowed position wherein the exit of the vehicle is substantially uncovered by the second safety barrier such that an occupant of the vehicle may egress through the exit substantially unimpeded by the second safety barrier, and

a second deployed position wherein the second safety barrier covers at least a portion of the exit in order to impede the occupant'"'"'s egress through the exit, and

wherein the second safety barrier is configured for continuous deployment in the second deployed position during the operation of the vehicle.

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.
