Abstract

A vehicle storage assembly includes a storage compartment having an opening to permit access to the compartment. A door adjacent the opening is moveable between a closed position that covers the opening and an open position that permits access to the compartment through the opening. The storage assembly further includes a controllable damper coupled to the door and actuable between high and low damping states, such that the door is maintained in one of the closed position, the open position, or any position therebetween when the controllable damper is in the high damping state. To move the door to a new position, the controllable damper is actuated from the high damping state to the low damping state whereby the door can then be freely moved to the desired position. The controllable damper may then be actuated from the low damping state to the high damping state to retain the door in the selected position.

Claims

1. A vehicle storage assembly for use within an interior of a vehicle, comprising:

a storage compartment adapted for use within the interior of the vehicle and having an opening to permit access to said compartment;

a door proximate said opening, said door movable between a closed position that covers said opening, and an open position away from said opening to permit access to said compartment through said opening;

a controllable damper coupled to said door and adjustable between high and low damping states, independent of the position of said door, to facilitate moving and maintaining said door between said open and closed positions;

a controller communicating with said controllable damper, said controller operable to actuate said controllable damper between said high and low damping states; and

a sensor communicating with said controller and adapted to sense the presence of an object in a path of said door between said closed position and said open position and to generate a signal when the presence of an object is sensed.

2. The storage assembly of claim 1, further comprising a switch associated with said controllable damper and operable to facilitate selective actuation of said controllable damper between said high and low damping states.

3. The storage assembly of claim 1, wherein said controllable damper is a magneto-rheological damper.

4. The storage assembly of claim 3, further comprising a permanent magnet associated with said controllable damper, said permanent magnet adapted to maintain said magneto-rheological damper in said high damping state without requiring power to be supplied to said damper.

5. The storage assembly of claim 4, further comprising:

a wire coil associated with said permanent magnet and configured to substantially negate a magnetic field produced by said permanent magnet when current is supplied to said wire coil to actuate said magneto-rheological damper from said high damping state to said low damping state.

6. The storage assembly of claim 1, wherein said controller adjusts said controllable damper to limit movement of said door between said closed position and said open position in response to said signal from said sensor.

7. The storage assembly of claim 1, wherein said signal is related to a distance between said door and the object.

8. The storage assembly of claim 7, wherein said controller adjusts said controllable damper to said high damping state when said door is a predetermined distance from the object, in response to said signal from said sensor.

9. A method of adjusting the position of a door of a storage assembly in a vehicle between a closed position that covers an opening to a storage compartment within the interior of the vehicle, and an open position wherein the door extends away from the opening to permit access to the compartment, the storage assembly including a controllable damper coupled to the door, the method comprising:

adjusting the controllable damper from a high damping state to a low damping state;

selectively adjusting the position of the door relative to the opening to the compartment;

adjusting the controllable damper from the low damping state to the high damping state such that the door is maintained in the adjusted positioned by the controllable damper;

sensing the presence of an object in a path of the door between the closed position and the open position; and

adjusting the controllable damper in response to the sensed object to limit movement of the door between the closed position and the open position.

10. The method of claim 9, wherein the controllable damper is a magneto-rheological damper.

11. The method of claim 10, wherein the storage assembly further includes a permanent magnet associated with the magneto-rheological damper, and wherein the magneto-rheological damper is actuated to the high damping state using the permanent magnet.

12. The method of claim 11, wherein the storage assembly includes a wire coil associated with the magneto-rheological damper, the method further comprising:

supplying an electric current through the wire coil to substantially negate a magnetic field produced by the permanent magnet and thereby actuate the magneto-rheological damper from the high damping state to the low damping state.

13. The method of claim 9, wherein adjusting the controllable damper in response to the sensed object comprises actuating the controllable damper from a low damping state to a high damping state.

14. The method of claim 9, further comprising:

selectively adjusting the controllable damper to a damping state intermediate the high damping state and the low damping state such that the resistance of the door to movement is adjusted.
