Vehicle frame components

Apparatus comprising:

• a frame component configured to be integrated in a vehicle structure, including:
• a first wall comprised of at least one metal sheet,
• a second wall comprised of at least one further metal sheet,
• wherein the first wall and the second wall bound a hermetically sealed interior gap, wherein the interior gap extends between the walls,
• a fluid connector,
• wherein the fluid connector is configured to deliver pressurized fluid through one of the first wall and the second wall and into the interior gap,
• wherein the delivered fluid is operative to increase strength of the frame component.

The apparatus according to 27

• wherein the frame component further includes:
• a hermetically sealed pocket within the interior gap,
• wherein the pocket includes a pocket wall that bounds a pocket interior area,
• wherein the delivered fluid is received to the pocket interior area,
• wherein the pocket wall is permanently deformed responsive to the fluid.

A method comprising:

• a) joining in engaged relation
• a first wall comprising at least one metal sheet and
• a second wall comprising at least one further metal sheet
• of a frame component configured to be integrated in a vehicle structure such that the first wall and the second wall bound a hermetically sealed interior gap between the walls,
• b) delivering via a fixed connector, pressurized fluid into the interior gap through the first wall or the second wall, wherein the delivered fluid is operative to increase strength of the frame component.
