Abstract

A system for use in a construction including a compartment to be protected from an explosive threat incoming from an expected threat direction. The construction comprises a surface disposed in front of the compartment and having at least a section thereof expected to be impacted by the explosive threat, and a component disposed between the surface and the compartment. The system comprises two cables, and an elongated element having two end portions and a bendable portion and being configured for mounting in the construction so that at least a part of the bendable portion is disposed between the section and the compartment and flexible towards the compartment to be protected, upon application thereto of a force caused by the explosive threat. Each cable is connectable at one end thereof to the component, and at the other end thereof is connected to one of the ends of the elongated element.

Claims

1. A system for use in a construction having a compartment to be protected from an explosive threat incoming from an expected threat direction, the compartment including peripheral portions, a surface having respective ends coupled to the peripheral portions of the compartment and disposed in front of the compartment relative to the threat direction and being spaced therefrom, the surface having at least a section thereof expected to be impacted by the explosive threat, and a component associated with the compartment and disposed between the surface and the compartment, the system comprising:

an elongated element having two end portions and a bendable portion, the elongated element being configured for mounting in said construction so as to be at least indirectly fixedly attached to the surface at or near the respective ends of the surface that are coupled to the peripheral portions of the compartment and so that at least a part of said bendable portion is disposed between said section and said compartment and is configured to flex towards the compartment to be protected, upon application thereto of a force caused by the explosive threat; and

two cables, each cable being connectable at one end thereof to the component, and at the other end thereof being connected to one of the ends of the elongated element so that flexing of the bendable portion towards the component causes pulling of the cables by the ends of the elongated element away from the component, thereby restricting the movement of the component towards the compartment to be protected.

2. The system of claim 1, wherein the elongated element is a cable and the elongated element and the two cables together constitute portions of a single continuous cable.

3. The system of claim 1, wherein the elongated element is a beam.

4. The system of claim 1, wherein the construction is a vehicle.

5. The system of claim 1, wherein the component has a first dimension of length and a second dimension of length smaller than, and transverse to, the first dimension;

the first dimension being the largest length of the component along an imaginary axis extending through the component from the section of the surface to the compartment to be protected;

the ends of the cables being configured to be connectable to the component at connection points which are each adjacent to axis points of the imaginary axis that are spaced from each other, so that the pulling of the cables causes rotation of the component.

6. The system of claim 1, wherein the construction is a vehicle and the component is a chassis of the vehicle.

7. The system of claim 1, further comprising at least one elongated bracket having first and second ends spaced from each other;

the first end of the at least one elongated bracket being configured to be mounted on the component;

at least one of the two cables being configured to be connectable to the component via connection with the second end of the at least one elongated bracket.

8. The system of claim 1, wherein the two end portions of the elongated element are configured to move in a direction away from the compartment to be protected, upon the application to the elongated element of the force caused by the explosive threat.

9. The system of claim 8, wherein the two end portions of the elongated element are configured to move in a direction away from the compartment to be protected by engagement with vertical walls of the construction.

10. The system of claim 1, wherein the system is part of an assembly including at least two such systems.

11. The system of claim 1, wherein the two cables are configured to be connected to the component in a normally taut state.

12. The system of claim 1, further comprising at least one additional cable for restricting upward motion of the component.

13. The system of claim 12, wherein the at least one additional cable engages an upper portion of the component.

14. The system of claim 12, wherein the component is a chassis and at least one additional cable is connected between two longitudinal beams of the chassis.

15. The system of claim 12, wherein the at least one additional cable is two cables, each connected at a first end thereof to one of the ends of the elongated element, and at a second end thereof to an one side of the component.

16. The system of claim 12, wherein the at least one additional cable is a plurality of cables which together form a net configuration.

17. The system of claim 1, wherein the component is reinforced at an upper section thereof in comparison to a lower section thereof to which the cables are connected.

18. The system of claim 1, being a part of an assembly comprising at least two such systems, the assembly further comprising at least one reinforcement element connected between adjacent systems for providing reinforcement thereto.

19. The system of claim 1, wherein the component is a cable.

20. The system of claim 1, wherein the component is an intermediary portion of a cable, the cable including said two cables each of which constitute a portion of the cable extending from alternative sides of the intermediary portion.
