Problems solved by technology

If winding and fastening is used, additional expense will come to the fastener and connecting the fastener to the sleeve
Also, additional labor and / or workmanship is often required to secure the sleeve around the wire
Thus, although the sleeve has proven generally useful in suppressing noise generation, consideration has been given to weaving, weaving or braiding, and attaching fasteners to the sleeve and securing the sleeve around the wire brought about by the additional cost, they are relatively expensive to manufacture

Embodiment Construction

[0016] Referring to the drawings, Figure 1 shows a nonwoven sleeve 10 made in accordance with a preferred embodiment of the present invention. The sleeve 10 has a wall 12 fabricated from a nonwoven material and shaped as a self-coiling tubular structure to define an enclosed lumen 16 when it is in a self-coiling state. The lumen 16 is tubular and easily accessible along the longitudinal axis 18, so that elongated members such as electrical wires 19 or harnesses can be easily inserted radially into the lumen 16 towards the axis 18, and vice versa, as in maintenance During this time, it is removed from the chamber 16. The nonwoven material forming said wall 12 is an abrasion resistant, flexible, resilient, noise reducing polyester material, which in the preferred embodiment is formed, by way of example and not limitation, of PET. Accordingly, the sleeve 10 is well adapted to protect the elongate member 19 within the cavity 16 against wear and damage, while also preventing the e...

Abstract

A non-woven acoustic sleeve and method of construction thereof provides routing and protection for elongate members and suppression of noise generation from the elongate members while in the sleeve. The sleeve has an elongate wall with opposite sides that are self-wrapping about a longitudinal axis to define a generally tubular cavity. The opposite sides are extendable away from one another under an externally applied force to allow the elongate members to be disposed radially into or removed from the cavity. When the external force is released, the opposite sides of the wall to return to their self wrapped configuration to enclose the elongate members and suppress noise therefrom.

Description

[0001] Cross References to Related Applications [0001] This application claims priority to US Provisional Application No. 60 / 790,733, filed April 10, 2006, the entire contents of which are incorporated herein by reference. technical field [0002] The present application relates generally to sleeves for protecting elongate members, and more particularly to nonwoven self-rolling acoustic protection sleeves for receiving elongate members. Background technique [0003] Electrical wires and wiring harnesses carried in the inner sleeves of vehicles such as automobiles, aircraft or spacecraft are known to generate undesired noise during operation of said vehicle. This noise typically originates from the vibration of the wires or harness relative to the sleeve and / or adjacent components, where the vibration arises from vibrating components in the vehicle, as well as from the driving conditions of the vehicle over the ground. In this regard, it is customary to helically wrap wire...
