Universal Cellphone Airbag

Every time one is forced to upgrade one's cellphone, a protective cell phone case is never included in the purchase price, and the old case never fits the new phone.

Enter the Universal Cellphone Airbag, modeled on the Hövding airbag helmet for cyclists. The UCA fits around the outside edge of the cellphone where it remains inert until the UCAapp detects sudden acceleration toward the floor, whereupon it deploys, encircling the phone, saving the entire phone including the very-expensive screen.

Strong thin nylon construction allows use of the buttons while the airbag lies inert around the phone. The ripstop nylon is textured to provide better grip on your phone. The edge of the airbag is anchored at the charging port with tiny bungees, so the port is unobstructed on any size cell phone.

Sold in packs of 3, so that you get 3 chances to adjust to your new phone's weight/dimensions.
