Abstract
Abstract The device consists of a moderately pretensioned wire cable which connects the opposing vehicle body sides together. The cable is fixed by means of a pair of opposing reinforcement plates of relatively large surface area that are welded and/or screwed to the vehicle body. The cable passes about the steering column in such a manner as to limit its rearward movement in case of a frontal impact between the vehicle and an obstacle and/or another vehicle and to simultaneously limit the movement of the body sides away from each other.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
144 words
A device for limiting the collapse of a structure of a vehicle during frontal impact, the vehicle comprising a body, a passenger compartment, and a steering column, the structure comprising a pair of opposing body sides forming a part of the body and laterally defining the passenger compartment, the steering column disposed parallel to the body sides, said device comprising: a) a pair of reinforcement plates, each of which is rigidly secured to an inner surface of the body sides that are likely to move away from each other in the event of a frontal impact; and b) a cable extending tautly across the passenger compartment in front of the steering column and secured to each of said reinforcement plates thereby to interconnect said reinforcement plates together so as to limit the movement of the body sides from each other during a frontal impact.
Claim 2
Independent Claim

A device for limiting the collapse of a structure of a vehicle during frontal impact, the vehicle comprising a body, a passenger compartment, and a steering column, the structure comprising a pair of opposing body sides forming a part of the body and laterally defining the passenger compartment, the steering column disposed parallel to the body sides, said device comprising: a) a pair of reinforcement plates, each of which is rigidly secured to an inner surface of the body sides that are likely to move away from each other in the event of a frontal impact; and b) a cable extending tautly across the passenger compartment in front of the steering column and secured to each of said reinforcement plates thereby to interconnect said reinforcement plates together so as to limit the movement of the body sides from each other during a frontal impact.
Claim 3
Dependent Claim
12 words
A device as in claim 1, wherein: a) said cable is pretensioned.
Claim 4
Dependent Claim
12 words
A device as in claim 1, wherein: a) said cable is metallic.
Claim 5
Dependent Claim
15 words
A device as in claim 1, and further comprising: a) means for tensioning said cable.
Claim 6
Dependent Claim
65 words
A device as in claim 1, and further comprising: a) a bracket rigidly connected to each of said reinforcement plates; b) means for securing said cable to the steering column; c) said brackets are disposed to the front of and diametrically opposite said securing means; and d) said cable is interconnected to said brackets and said securing means so as to form a closed loop.
Claim 7
Dependent Claim
97 words
A device as in claim 5, wherein said securing means comprises: a) a pair of pulleys each of which is secured to opposite sides of the steering column; b) a U-shaped member secured to one end of the steering column in the passenger compartment; and c) said cable is arranged such that said cable defines in plan view a closed loop having a first portion extending tautly between said brackets, second and third portions each extending tautly and obliquely between respective said brackets and said pulleys and a fourth portion engaging said U-shaped member and said pulleys.
