Abstract

A connector-type securing element for attaching one lockcarrying part of a vehicle safety harness to the vehicle floor. The element consists of extensible synthetic resin threads wound about two spaced-apart trundles, and a plastic cover completely enclosing the thread and trundle unit. The cover preferably is made of a material with a lower tensile strength value than the threads enclosed therein such that upon abnormal elongated stresses on the harness, such as for instance in case of an accident, the cover will break, providing a readily visible indication that the harness is no longer fit for use and should be replace.

Claims

1. In an improved securing element for supporting one of the two locking parts of a vehicle safety harness, said securing element having one attachment means at one end for attachment to the vehicle floor and one attachment at the opposite end for supporting said one locking part, the improvement wherein said securing element comprises threads of an extensible synthetic resin, spaced apart trundles made of plastics and having annular border flanges thereon, said threads being spun about said trundles in loops, and a plastic cover in which the unit thus formed from said threads and said trundles is completely embedded by means of die-casting.

2. An improved securing element as defined in claim 1, wherein said threads consist essentially of polyester fibers.

3. An improved securing element as defined in claim 1, wherein longitudinally extending reinforcement ribs are provided on said plastic cover.

4. An improved securing element as defined in claim 1, wherein a rigid plastic material is used for said cover, said rigid plastic material being such as to break upon elongation stresses of about 10 percent exerted on the threads enclosed in said cover, whereby a visible indication is obtained on such cover that the harness has been exposed to abnormal elongation stresses.

5. In an improved securing element for supporting one of two locking parts of a vehicle safety harness, said securing element having attachment means at one end thereof for attachment to the vehicle floor and attachment means at the opposite end thereof for supporting one of said locking parts, the improvement wherein said securing element comprises threads formed from extensible synthetic resin material, spaced apart trundles made of plastic and having annular border flanges thereon, said threads being spun about said trundles in loops, and a plastic cover enclosing said threads and said trundles, said cover being structured to rupture upon a predetermined tensile stress elongation of said threads.

6. A securing element according to claim 5 wherein said plastic cover is essentially formed of material having a lower tensile strain value than the material of said threads.

7. A securing element according to claim 5 wherein said plastic cover is constructed to rupture upon occurrence of approximately 10% tensile stress elongation of said threads.
