Impact-attenuation members and products containing such members

A device comprising:

• a first arched body portion;
• a second arched body portion facing the first arched body portion, wherein the first arched body portion and the second arched body portion, at least in part, define a base orientation of the device and wherein an open space is defined between the first arched body portion and the second arched body portion;
• and
• a first spring member at least partially included in the open space and extending to at least substantially contain the first arched body portion and the second arched body portion,
• wherein when a force is applied to at least one of the first arched body portion or the second arched body portion so as to change the device out of the base orientation, the first spring member exerts a force that urges the device toward the base orientation,
• wherein the first spring member includes a polymeric element that stretches under a tensile force when the force is applied to at least one of the first arched body portion or the second arched body portion.

A device comprising:
