Abstract
Abstract The disclosure relates to improvements in or relating to the safety barrier, especially for freeways, constituting the subject matter of U.S. Pat. No. 4,062,521. Each module of the safety barrier comprises a casing 5 consisting of a stack of pneumatic tires 3 divided into units 6 and covered with a coating or outer covering 7, notches 8 being provided for the passage of the linear element or elements 2. Especially useful for the safety of vehicles, particularly on freeways.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
91 words
A safety barrier comprising a plurality of modules coupled to one another by at least one embedded linear element under tension, said modules each being composed of an integral material subject to bursting as a result of internal tension due to said linear element passing through the modules and embedded therein so that any module struck by a car involved in an accident bursts together with adjacent modules and a flexible casing surrounding each module and preventing ejection of debris and fragments of materials upon impact and bursting of the module.
Claim 2
Dependent Claim
91 words
A safety barrier comprising a plurality of modules coupled to one another by at least one embedded linear element under tension, said modules each being composed of an integral material subject to bursting as a result of internal tension due to said linear element passing through the modules and embedded therein so that any module struck by a car involved in an accident bursts together with adjacent modules and a flexible casing surrounding each module and preventing ejection of debris and fragments of materials upon impact and bursting of the module.
Claim 3
Dependent Claim
15 words
The safety barrier of claim 1 wherein the casing comprises a stack of pneumatic tires.
Claim 4
Dependent Claim
25 words
The safety barrier of claim 2, wherein said stack includes at least two separate superimposed units, and each unit has at least two pneumatic tires.
Claim 5
Dependent Claim
20 words
The safety barrier of claim 3, wherein said units are three in number and each unit has two pneumatic tires.
Claim 6
Dependent Claim
19 words
The safety barrier of claims 3 or 4, wherein said casing includes a pneumatic tire located within said stack.
Claim 7
Dependent Claim
21 words
The safety barrier of claims 2 or 3, wherein said casing includes an external cover of pulverized rubber and plastic binder.
Claim 8
Dependent Claim
14 words
The safety barrier of claim 6, wherein said cover is cast around said tires.
Claim 9
Dependent Claim
24 words
The safety barrier of claim 6, wherein said casing and said cover are provided with openings to allow the introduction of the linear element.
Claim 10
Dependent Claim
106 words
A safety barrier comprising a plurality of modules coupled to one another by at least one linear element under tension, said modules each being composed of a material bursting as a result of internal tension due to said linear element passing through the modules and embedded therein so that any module struck by a car involved in an accident bursts together with adjacent modules and a flexible casing surrounding each module and preventing ejection of debris and fragments of materials upon impact of a module, wherein the casing comprises a stack of pneumatic tires, and wherein said casing includes a pneumatic tire located within said stack.
Claim 11
Dependent Claim
106 words
A safety barrier comprising a plurality of modules coupled to one another by at least one linear element under tension, said modules each being composed of a material bursting as a result of internal tension due to said linear element passing through the modules and embedded therein so that any module struck by a car involved in an accident bursts together with adjacent modules and a flexible casing surrounding each module and preventing ejection of debris and fragments of materials upon impact of a module, wherein the casing comprises a stack of pneumatic tires, and wherein said casing includes a pneumatic tire located within said stack.
Claim 12
Dependent Claim
89 words
A safety barrier comprising a plurality of modules coupled to one another by at least one linear element under tension, said modules each being composed of a material bursting as a result of internal tension due to said linear element passing through the modules and embedded therein so that any module struck by a car involved in an accident bursts together with adjacent modules and a flexible casing with an external cover surrounding each module and preventing ejection of debris and fragments of materials upon impact of the module.
Claim 13
Dependent Claim
89 words
A safety barrier comprising a plurality of modules coupled to one another by at least one linear element under tension, said modules each being composed of a material bursting as a result of internal tension due to said linear element passing through the modules and embedded therein so that any module struck by a car involved in an accident bursts together with adjacent modules and a flexible casing with an external cover surrounding each module and preventing ejection of debris and fragments of materials upon impact of the module.
