Abstract
A protective case for an electronic device may have two layers: an inner cushion cover that surrounds a portion of the electronic device, and an outer shell that surround part of the cushion cover. The outer shell has side walls that engage and hold the cushion cover on the electronic device. The cushion cover has reduced thickness portions so that the side walls are embedded in the cushion cover and provide a protective case having a substantially smooth exterior. The cushion cover is capable of absorbing shocks from impacts on the rigid outer shell. Coring on the inner portion of the cushion cover provides additional softness and the ability of the cushion cover to absorb shocks while using a higher density material, which is able to conform to the electronic device.

9. A method of manufacturing a protective case for an electronic device, comprising:
-
forming a cushion cover of an elastomeric material, the cushion cover structured to cover a portion of the electronic device and having a density and elasticity that cause the cushion cover to conform to the electronic device when installed thereon, the cushion cover having a cushion back and a cushion side wall that extends from the cushion back, the cushion cover having an interior surface that is formed to contact an outer surface of the installed electronic device, the cushion cover having reduced thickness portions along an exterior surface of the cushion back and the cushion side wall; forming a rigid outer shell from a plastic material, the outer shell being removably separate from the cushion cover, the outer shell having a shell back corresponding to the reduced thickness portion of the cushion back, and a plurality of separated shell side walls, the shell back formed to a shape of a back surface of the electronic device, the shell side walls connected to and extending from the shell back, the shell side walls having rigidity sufficient to substantially maintain position relative to the shell back while pressing portions of the reduced thickness portions of the cushion side wall against the electronic device when the electronic device is at least partially covered by the cushion cover, at least one of the shell side walls having a thickness that permits resilient flexibility during installation and removal of the outer shell from the cushion cover of the protective case, forming a raised impact portion of the cushion side wall, the raised impact portion disposed at a region of the cushion side wall to correspond to a perimeter separation between the separated shell side walls, wherein a predetermined thickness of the raised impact portion is greater than a thickness of other portions of the cushion cover, and forming a plurality of recesses in and distributed across a portion of the interior surface of at least the cushion back and cushion side wall of the cushion cover, the recesses reducing density of the interior surface of at least the cushion back and cushion side wall of the cushion cover that is adjacent to the electronic device when the protective case covers at least a portion of the electronic device, forming a pointed hook on each of the shell side walls, each pointed hook configured to engage an outer surface of the cushion cover and further maintain position of the rigid outer shell against the cushion cover, and forming in the cushion cover a die cut plug, an edge portion of the die cut plug attached to the cushion cover, the die cut plug being flexibly movable from a closed position to an open position for access to a port of the electronic device, the die cut plug having a nipple extending from an inner surface of the die cut plug, the nipple having a perimeter structure corresponding to dimensions of the port of the electronic device, wherein while the protective case is installed on the electronic device, the nipple of the die cut plug has an interference fit to the port of the electronic device when the die cut plug is in the closed position, and the nipple is disposed away from the port of the electronic device when the die cut plug is in the open position. - View Dependent Claims (10, 11, 12, 13, 14, 15)
