Patent number: 9273752Abstract: Truck fairings are connected together with a vibration-isolating bracket device. The device includes three parts: two brackets and a strap. The brackets are a lightweight material such as aluminum. The brackets are formed and configured to be coupled together by the strap without the need for further fasteners such as bolts or rivets. The strap is flexible and elastic and provides vibration isolation as well as coupling.Type: GrantFiled: November 3, 2014Date of Patent: March 1, 2016Assignee: Hutchinson Aerospace & Industry, Inc.Inventors: Michael D. Thomas, William Hart, Franck Larmande
