Abstract: Helmet assembly for light impacts. The assembly includes a soft helmet with recesses on the helmet inner surface. Detachable pads are configured to fit in the recesses, to provide soft inner protection for the wearer. Detachable shims are configured to fit in between the pads and recesses in order to properly fit the helmet to the wearer.

Abstract: Apparatus for protecting a user from impacts to the head. The apparatus includes a shell configured to receive a human head and a face mask coupled to the shell by a plurality of biasing mechanisms. The face mask is configured to reorient relative to the shell upon impact. The biasing mechanisms return the face mask to its original relative position after impact.

Abstract: Apparatus for protecting a user from impacts to the head. The apparatus includes a shell configured to receive a human head and a plurality of structures attached to the outer surface of the shell. Each structure includes an outer cell that absorbs direct impacts. Each structure is independently coupled to the shell with a respective assembly. The structures move independently of one another and are restricted to sliding tangentially along the outer surface of the shell. The assemblies each include a biasing mechanism that absorbs tangential impacts to the structure and returns the respective structure to its rest position. Thus, a user is protected from the concussive effects of a head-on impact and the rotational acceleration injuries of a tangential impact.

Abstract: Apparatus for protecting a user from impacts to the head. The apparatus includes a shell configured to receive a human head and a plurality of structures attached to the outer surface of the shell, where each structure is independently coupled to the shell with a respective assembly. The structures move independently of one another but are restricted to moving laterally along the outer surface of the shell. The structures each include a foam cell that reduces the magnitude of a head-on impact as the impact transfers from the foam cell to the shell. The assemblies each include an elastomeric donut that reduces the magnitude of a lateral impact as the impact is transferred from the foam cell to the donut assembly to the shell. Thus, a user is protected from the concussive effects of a head-on impact and the rotational acceleration injuries of a lateral impact.

Abstract: A furniture glide is mountable on the foot of a furniture leg. The glide is constructed around a glide base having an inner portion and foot support surface. A plurality of spring fingers positioned on the glide base have attached and distal ends. The distal ends extend in an inward direction toward the inner portion of the glide base. The distal ends also extend in an outward direction away from the foot support surface. The positioning of heads at about the distal end of each spring finger allows the spring fingers to receive an outward expansion force when the foot is moved toward the foot support surface. The spring fingers are positioned to move in an inward direction toward the inner portion of the glide base to lock the foot to the furniture glide when the foot contacts the foot support surface.
