A side impact protection system for a motor vehicle body having a stowed position and a deployed position, the system includes a first L-shaped rigid structure comprising a first portion and a second portion; a second L-shaped rigid structure comprising a first portion and a second portion; a synthetic cable fixedly attached to the second portions of the first and second L-shaped rigid structures, wherein the synthetic cable is made from a plurality of helically braided bundles of fibers selected from a group consisting of aramid fibers and liquid crystal polymer fibers characterized by strain-at-failure exceeding about 3 percent; and a deployment device in operative communication with the first portions of the first and second L-shaped rigid structures to selectively extend the first portion outwardly from the deployment device, and wherein in a stowed position the second portions are at about the same plane and in a deployed position the second portions are parallel and the synthetic cables form a web-like structure. Processes for suppressing intrusion into a passenger compartment of a motor vehicle body by an object laterally impacting the vehicle body are also described.

The motor vehicle body of claim 1, further comprising a horizontal beam in a door spanning a door frame and defining a second side impact protection barrier on the vehicle body for suppressing intrusion into a passenger compartment by an object laterally impacting the vehicle body.3. The motor vehicle body of claim 1, wherein the web-like structure forms an X pattern. 4. The motor vehicle body of claim 1, further comprising a sensor in communication with the deployment device for communicating an imminent impact event to the deployment device.5. The motor vehicle body of claim 1, wherein the deployment device is reversible.6. The motor vehicle body of claim 1, wherein the deployment device is irreversible.7. The motor vehicle body of claim 1, wherein the synthetic cables form a web-like structure that is spaced apart from a side of the motor vehicle body.8. A side impact protection system for a motor vehicle body having a stowed position and a deployed position, the system comprising:a first L-shaped rigid structure comprising a first portion and a second portion (66);a second L-shaped rigid structure comprising a first portion and a second portion;a synthetic cable fixedly attached to the second portions of the first and second L-shaped rigid structures, wherein the synthetic cable made from a plurality of helically braided bundles of fibers selected from a group consisting of aramid fibers and liquid crystal polymer fibers characterized by strain-at-failure exceeding about 3 percent; anda deployment device in operative communication with the first portions of the first and second L-shaped rigid structures to selectively extend the first portion outwardly from the deployment device, and wherein in a stowed position the second portions are at about the same plane and in a deployed position the second portions are parallel to one another, perpendicularly oriented relative to ground and the synthetic cables attached to the second portions form a web-like structure. 9. The side impact protection system of claim 8, wherein the web-like structure forms an X pattern.10. The side impact protection system of claim 8, further comprising a sensor for communicating an imminent impact event to the deployment device.11.
