Variable friction cargo surface system for vehicles

A cargo system for a vehicle, the cargo system comprising:

• a variable cargo surface configured to be disposed within a body of the vehicle, the variable cargo surface comprising:
• a low friction surface that facilitates movement of cargo within the cargo system, the low friction surface having a first coefficient of friction;
• and
• a high friction surface that inhibits movement of cargo within the cargo system, the high friction surface having a second coefficient of friction that is greater than the first coefficient of friction;
• a control device that selectively activates one or both of the low friction surface and the high friction surface based on conditions of the vehicle, wherein:
• the low friction surface contacts the cargo within the cargo system when the low friction surface is activated;
• and
• the high friction surface contacts the cargo within the cargo system when the low friction surface is deactivated;
• one or more chambers that are fully integrated with one or both of the low friction surface and the high friction surface, wherein the chamber is configured to receive fluid for selectively activating the one or both of the low friction surface and the high friction surface;
• and
• one or more fluid movement devices configured to move fluid into and out of the one or more chambers, to thereby selectively activate and deactivate the low friction surface, wherein the one or more fluid movement devices comprise:
• a pump configured to move fluid into the one or more chambers, to thereby selectively activate the low friction surface;
• and
• a vacuum configured to remove fluid out of the one or more chambers, to thereby deactivate the low friction surface.

A vehicle comprising:

• a body;
• one or more occupant seats disposed within the body;
• and
• a cargo system comprising:
• a variable cargo surface disposed within the body of the vehicle behind one or more of the occupant seats, the variable cargo surface comprising:
• a low friction surface that facilitates movement of cargo within the cargo system, the low friction surface having a first coefficient of friction;
• a high friction surface that inhibits movement of cargo within the cargo system, the high friction surface having a second coefficient of friction that is greater than the first coefficient of friction;
• a control device that selectively activates and deactivates the low friction surface based on conditions of the vehicle, wherein:
• the low friction surface contacts the cargo within the cargo system when the low friction surface is activated;
• and
• the high friction surface contacts the cargo within the cargo system when the low friction surface is deactivated;
• a chamber coupled to the low friction surface, the chamber configured to receive fluid for activating and deactivating the low friction surface;
• and
• one or more fluid movement devices configured to move fluid into and out of the chamber, to thereby selectively activate and deactivate the low friction surface, wherein the one or more fluid movement devices comprise:
• a pump configured to move fluid into the chamber, to thereby selectively activate the low friction surface;
• and
• a vacuum configured to remove fluid out of the chamber, to thereby deactivate the low friction surface.
