Composite reinforced sealing strip, for use for example on an automobile body, the strip being made up of a sealing part and of a U-shaped gripping part integrally connected lengthwise to the sealing part and a reinforcing armature embedded in the gripping part. This armature has a body which is formed of a series of spaced parallel U-shaped elements with connecting struts joining only the bights of two elements of consecutive pairs of elements and other connecting struts joining only the adjacent legs of the consecutive pairs of elements. Thus, the first and second elements of every three consecutive elements are joined together solely at the bights and the second and third elements are joined together solely at the legs. |

DETAILED DESCRIPTION I claim: 1.
A composite reinforced sealing strip, for use for example on a vehicle body, said strip comprising: a sealing part and a U-shaped gripping part integrally connected together lengthwise thereof; a reinforcing armature embedded in said U-shaped gripping part and comprising: a body formed of a series of like-oriented spaced parallel U-shaped elements each having a central bight and two legs depending therefrom, connecting struts joining only the bights of the two elements of consecutive pairs of elements and further connecting struts joining only the adjacent legs of said consecutive pairs of elements, whereby the first and second elements of every three consecutive elements are joined together solely at the bight and the second and third elements are joined together solely at the legs, and an elongated substantially inextensible member embedded between said parts to extend longitudinally thereof.
2.
A sealing strip as claimed in claim 1, wherein the struts join the bights at the center thereof and the legs likewise at the center thereof.
3.
A sealing strip as claimed in claim 1 or claim 2, wherein said inextensible member is a thread.
4.
A sealing strip as claimed in claim 1 or in claim 2 wherein said inextensible member is a ribbon.
5.
A composite reinforced sealing strip, for use for example on a vehicle body, said strip comprising: a sealing part and a U-shaped gripping part integrally connected together lengthwise thereof, said gripping part being composed of an extruded material; a reinforcing armature embedded in said U-shaped gripping part and comprising: a body formed of a series of like-oriented spaced parallel U-shaped elements each having a central bight and two legs depending therefrom, connecting struts joining only the bights of the two elements of consecutive pairs of elements and further connecting struts joining only the adjacent legs of said consecutive pairs of elements, whereby the first and second elements of every three consecutive elements are joined together solely at the bight and the second and third elements are joined together solely at the legs; and means for reducing any tendency of the sealing strip to collapse by controlling the extent to which the sealing strip may bend, said reducing means including an inextensible strand which is embedded in said extruded material of said gripping part and which extends lengthwise of said gripping part
