The loop is thus distended in such a manner that the vesti-bule end of an invading car will penetrate within the initial shock of collision will be met as now by the vesti-bule end posts. When the resistance of these end posts isovercome and as the invading body progresses, the cable loop,together with the members of the invaded vestibule will bedrawn in and down against the vestibule of the invadingbody crushing both within the confines of the loop. The more resistant the structures thus crushed, the greaterwill be the energy absorbed and the greater will be the pull. End View of the Car Shown in the Last Illustration exerted by the cable, through its anchorage in the underframe,to impart motion to the mass. The design further provides for a second group of cables,imbedded in the body corner posts and. body end frame, to actas a second line of defence against the invading car. Shouldthe force of the collision be not completely dissipated throughthe resistance of the vestibule end posts and the cable in thevestibule end, the invading car body will next encounter thehigh resistance of the body end wall, and the second group ofcables will come into action upon being encountered by theinvader. The second group of cables being also anchored tothe underframe and distended in loop form will also drawthe structure of the invaded car down and in upon the invaderand similarly impart motion to the mass. This second groupof cables will also act to draw downward and inward theroof and sides of the invader. The size and number of
