A shelf can have an underside and an opposed upper surface that defines a plane. The shelf can be pivotably coupled to the stanchions about an axis about and between a stowed position and a use position. The axis can extend through the plurality of stanchions at a location above the plane when the shelf is in the use position. At least one biasing element can be disposed at least partially within the slot and configured to bias the shelf toward the stowed position. ## Claims ### Claim 1 A shelf assembly comprising: a plurality of stanchions, each stanchion having an axis of elongation and comprising a pair of parallel or generally parallel legs that define a slot therebetween and respective front edges; a shelf having an underside and an opposed upper surface that at least partially defines a plane, wherein the shelf is pivotably coupled to the stanchions about an axis, wherein the shelf is pivotable about and between a stowed position and a use position, wherein the axis extends through the plurality of stanchions at a location above the plane when the shelf is in the use position; and at least one biasing element having a first end, a second end, and a spring therebetween, wherein the spring of each biasing element of the at least one biasing element is disposed at least partially within the slot of a respective stanchion and configured to bias the shelf toward the stowed position. ### Claim 2 (depends on 1) The shelf assembly of claim 1, wherein, when in the stowed position, the plane is generally parallel to the axes of elongation of the stanchions. ### Claim 3 (depends on 1) The shelf assembly of claim 1, wherein, when in the stowed position, the upper surface of the shelf is disposed against the front edges of the plurality of stanchions. ### Claim 4 (depends on 1) The shelf assembly of claim 1, wherein, when the shelf assembly is in the use position, the axis is vertically spaced from the plane by between about 0.5 inches and about 3.0 inches. ### Claim 5 (depends on 1) The shelf assembly of claim 1, wherein the shelf has a distal edge, wherein the distal edge defines a flange that extends at an obtuse angle from the plane and above the plane when the shelf is in the use position. ### Claim 6 (depends on 5) The shelf assembly of claim 5, wherein the flange has a first end that intersects the upper surface of the shelf and an opposed second end, wherein the second end comprises a rolled edge. ### Claim 7 (depends on 6) The shelf assembly of claim 6, wherein the rolled edge of the flange has a tear-shaped profile. ### Claim 8 (depends on 1) The shelf assembly of claim 1, further comprising a plurality of support arms, wherein each support arm of the plurality of support arms is pivotably attached to a respective stanchion of the plurality of stanchions about the axis, wherein each respective support arm is coupled to the underside of the shelf, and wherein the shelf is pivotably coupled to the plurality of stanchions via the plurality of support arms. ### Claim 9 (depends on 8) The assembly of claim 8, wherein each respective support arm comprises a base wall and a pair of spaced parallel walls that extend perpendicularly or substantially perpendicularly to the base wall. ### Claim 10 (depends on 8) The shelf assembly of claim 8, wherein the at least one biasing element is pivotably coupled to, and extends between, a respective stanchion and a respective support arm. ### Claim 11 (depends on 1) The shelf assembly of claim 1, wherein the at least one biasing element comprises at least one gas spring. ### Claim 12 (depends on 1) The shelf assembly of claim 1, further comprising a pair of horizontal rails that extend perpendicularly or substantially perpendicularly to the axes of elongation of the stanchions, wherein the horizontal rails attach to opposing first and second ends of each stanchion. ### Claim 13 (depends on 9) The shelf assembly of claim 9, wherein the at least one biasing element further comprises a first rod eye at the first end of the biasing element and a second rod eye at the second end of the biasing element, wherein the first rod eye is disposed at least partially within the slot of the respective stanchion, and wherein the second rod eye is disposed at least partially between the pair of spaced parallel walls of a respective support arm. ### Claim 14 (depends on 13) The shelf assembly of claim 13, wherein a first pin extends through the first rod eye and the slot of a respective stanchion of the plurality of stanchions, and wherein a second pin extends through the second rod eye and the pair of spaced parallel walls of a respective support arm. ### Claim 15 (depends on 1) The shelf assembly of claim 1, wherein the shelf is a first shelf of a plurality of shelves, wherein the plurality of shelves of the shelf assembly further comprises a second shelf that is pivotable about the axis. ### Claim 16 (depends on 15) The shelf assembly of claim 15, wherein the second shelf is independently pivotable with respect to the first shelf. ### Claim 17 (depends on 5) The shelf assembly of claim 5, wherein at least a portion of the flange is positioned vertically above the plurality of stanchions when the shelf is in the stowed configuration. ### Claim 18 A shelf assembly comprising: a plurality of stanchions, each stanchion having an axis of elongation and comprising a pair of parallel or generally parallel legs that define a slot therebetween and respective front edges; a shelf having an underside and an opposed upper surface that at least partially defines a plane; and a plurality of support arms, wherein each support arm of the plurality of support arms includes a proximal end and a distal end, the proximal end defining a hinge portion and a stop, the hinge portion being pivotally attached to a respective stanchion of the plurality of stanchions about an axis, wherein each respective support arm is coupled to the underside of the shelf so that the shelf is pivotably coupled to the plurality of stanchions about the axis via the plurality of support arms, and wherein the shelf is pivotable about and between a stowed position and a use position, wherein the axis extends through the plurality of stanchions at a location above the plane when the shelf is in the use position, and wherein the hinge portion of each support arm is disposed in the slot defined between the parallel legs of the respective stanchion, and each stop engages the front edges of the parallel legs of the respective stanchion when the shelf is in the use position. ### Claim 19 (depends on 18) The shelf assembly of claim 18, further comprising at least one biasing element that is configured to bias the shelf toward the stowed configuration. ### Claim 20 A vehicle comprising a shelf assembly, the shelf assembly comprising: a plurality of stanchions, each stanchion having an axis of elongation and comprising a pair of parallel or generally parallel legs that define a slot therebetween and respective front edges; a shelf having an underside and an opposed upper surface that at least partially defines a plane, wherein the shelf is pivotably coupled to the stanchions about an axis, wherein the shelf is pivotable about and between a stowed position and a use position, wherein the axis extends through the plurality of stanchions at a location above the plane when the shelf is in the use position; and at least one biasing element including a first end, a second end, and a spring disposed therebetween, wherein the spring of each biasing element of the at least one biasing element is disposed at least partially within the slot of a respective stanchion and configured to bias the shelf toward the stowed position.
