Abstract: An airbelt is provided that passes smoothly through an anchor and winds around a retractor. The airbelt includes a non-inflating section and a flat hollow-cylindrical inflating section. A bag is arranged only within the inflating section. An end of the bag as well as an end of the belt is connected to a tongue. The non-inflating section is inserted into a through-anchor and is connected to a retractor so as to enable to be wound up around and pulled out of the retractor. The belt is consecutively and integrally made by knitting or weaving all the parts extending from the non-inflating section toward the inflating section. A weft thread, which is lined up with a fusion thread such as a thread having a core-sheath structure, is inserted into the non-inflating section so as to be processed with heat.

Abstract: An environmental detection system is particularly suited for elevator hoistways and other locations where access is difficult or restricted. The inventive system comprises a fire rated access cage which is disposed within the hoistway in a desired location, and is securely attached to an associated access panel, which is fire protection rated and positioned to extend through a wall defining the hoistway. An environmental sensing device, such as a smoke detector or heat sensor, is secured within the cage so that it is disposed within the hoistway, and can freely detect any smoke or excessive heat present in the hoistway because of a large number of apertures in the walls of the cage. The resultant system, thus, is constructed so that authorized personnel can access the environmental sensing unit conveniently through the access panel door from an adjacent hallway or room to test or maintain it, without shutting down the associated elevator or compromising the effectiveness of the unit.
