Abstract

Blast absorbing structures and system for use in absorbing blast forces exerted on a floor of a personnel cabin of a vehicle, are disclosed. The blast absorbing flexing structure comprises a bottom section forming a floor of the cabin, a first side section and opposing second side section, each side section extending from the bottom section and including a plurality of steps along a length of the second side section. The steps flex in response to a blast force. In another embodiment, the blast absorbing expanding structure comprises a force abatement device forming a floor of the cabin, a cover plate having a plurality of slots arranged around a perimeter of the plate. The cover plate is movable between a neutral position and a blast force position to diminish the blast forces prior to the blast forces to reaching an occupant of the cabin.

First claim

What is claimed is:

1. A blast absorbing expanding structure for use in absorbing blast force energy exerted on an underside of a personnel cabin of a vehicle, the assembly comprising:
a force abatement device forming a floor of the cabin;
a cover plate having a plurality of slots arranged around a perimeter of the plate, the cover plate attached to a top surface of the device; and,
wherein the cover plate is movable between an initial position and a blast force position to diminish the blast forces from reaching an occupant of the cabin.

2. The blast absorbing expanding structure of claim 1 , wherein the slots are arranged in a plurality of rows.

3. The blast absorbing expanding structure of claim 2 , wherein the number of rows may vary to adjust the movement of the plate between the initial position and the blast force position.

4. The blast absorbing expanding structure of claim 1 wherein the structure further includes at least one energy absorbing support.

5. The blast absorbing expanding structure of claim 4 , wherein the energy absorbing support receives an initial blast force exerted on the underside of the vehicle.

6. A blast absorbing moveable structure for use in absorbing blast force energy exerted on an underside of a personnel cabin of a vehicle comprising:
a force abatement device forming a floor of the cabin;
a protective panel positioned over the device; and,
a plurality of energy absorbing slots arranged within the panel, wherein the panel is movable between a neutral position and a blast force position upon application of the blast force on the underside of the cabin and dissipation of blast force energy through the slots.
