Abstract: An airbag system secured to the tire rim inside a tire. The airbag is normally in a collapsed state close to the rim. The airbag is inflated with pressurized gas in the event of a tire failure. The inflated bag generally conforms to the inner walls of the tire to support the weight of the vehicle and enable the vehicle to be safely stopped. The bag has wear surfaces composed of durable material such as nylon or Kevlar fibers.

Abstract: A coupling system for connecting or attaching a working tool to the free end of a working arm. For example, a bucket, hammer, etc. can be easily attached to the end of an articulated arm on an excavator. The coupling system includes a fixed jaw and a movable jaw which is pivotable between open and closed positions. The movable jaw includes a tab which extends through an opening in the coupler housing. A single pin is used to lock the movable jaw in its closed position.
