The bearing may include a plurality of feet engaged with a plurality of apertures of the second seat track. A first aperture of the plurality of apertures may be disposed in a first side of the second seat track and/or a second aperture of the plurality of apertures may be disposed in a second side of the second seat track. The first side may be disposed substantially perpendicularly to the second side. The plurality of feet may include a first foot, a second foot, a third foot, and/or a fourth foot. ## Claims ### Claim 1 A seat track assembly, comprising: a first seat track; a second seat track configured to slide relative to the first seat track; a cross member; and a bearing connecting the cross member to the second seat track, the bearing including a plurality of feet engaged with a plurality of apertures of the second seat track; wherein a first aperture of the plurality of apertures is disposed in a top side of the second seat track and a second aperture of the plurality of apertures is disposed in a lateral side of the second seat track; and the bearing is configured to be inserted into the first aperture and then moved into the second aperture. ### Claim 2 (depends on 1) The seat track assembly of claim 1, wherein the plurality of feet includes a first foot, a second foot, a third foot, and a fourth foot. ### Claim 3 (depends on 2) The seat track assembly of claim 2, wherein the first foot includes a first portion, a second portion, and a third portion; the first portion is disposed substantially perpendicularly to a bottom of a body of the bearing; the second portion is disposed substantially perpendicularly to the bottom of the body; the first portion and the second portion are disposed substantially perpendicularly to each other; the third portion is disposed at ends of the first portion and the second portion; the third portion is disposed substantially parallel to the bottom of the body; and the third foot and the fourth foot are substantially L-shaped. ### Claim 4 (depends on 1) The seat track assembly of claim 1, wherein the bearing includes a retaining tab engaged with a retaining aperture of the second seat track; and the retaining aperture is separate and distinct from the plurality of apertures. ### Claim 5 (depends on 2) The seat track assembly of claim 2, wherein the plurality of apertures includes a third aperture disposed in the top side of the second seat track, and a fourth aperture disposed in the lateral side of the second seat track. ### Claim 6 (depends on 5) The seat track assembly of claim 5, wherein the first foot and the second foot are configured to engage the first aperture and the second aperture, and are disposed in parallel to a longitudinal direction of the first seat track. ### Claim 7 (depends on 6) The seat track assembly of claim 6, wherein the third foot and the fourth foot are configured to engage the third aperture and the fourth aperture, and are disposed parallel to the longitudinal direction of the first seat track and offset from the first foot and the second foot. ### Claim 8 (depends on 1) The seat track assembly of claim 1, further comprising a third seat track, a fourth seat track configured to slide relative to the third seat track, a second bracket connecting the cross member to the fourth seat track, the second bracket including a plurality of feet engaged with a plurality of apertures of the fourth seat track. ### Claim 9 (depends on 1) The seat track assembly of claim 1, wherein the bearing comprises plastic. ### Claim 10 (depends on 9) The seat track assembly of claim 9, wherein the bearing is a single integrated component. ### Claim 11 A bearing, comprising: a body comprising: a cross member receiving portion including a bearing surface configured to facilitate rotation of a cross member; and a plurality of feet configured to engage apertures of a movable track; wherein the cross member receiving portion and the plurality of feet are formed as a single, unitary component; a foot of the plurality of feet is configured for insertion into a first side of said movable track from a first direction; and another foot of the plurality of feet is configured for insertion into a second side of said movable track from a second direction that is substantially perpendicular to the first direction. ### Claim 12 (depends on 11) The bearing of claim 11, wherein the plurality of feet includes a a first additional foot and a second additional foot. ### Claim 13 (depends on 12) The bearing of claim 12, wherein the foot and the first additional foot are substantially identical. ### Claim 14 (depends on 13) The bearing of claim 13, wherein the another foot and the second additional foot include a different shape than the foot and the first additional foot. ### Claim 15 (depends on 13) The bearing of claim 13, wherein the foot includes a first portion, a second portion, and a third portion, wherein the first portion is disposed substantially perpendicularly to a bottom of the body, the second portion is disposed substantially perpendicularly to the bottom of the body, and the first portion and the second portion are disposed substantially perpendicularly to each other. ### Claim 16 (depends on 15) The bearing of claim 15, wherein the third portion is disposed at ends of the first portion and the second portion, and the third portion is disposed substantially parallel to the bottom of the body. ### Claim 17 (depends on 16) The bearing of claim 16, wherein the another foot and the second additional foot are substantially L-shaped. ### Claim 18 (depends on 14) The bearing of claim 14, further comprising a retaining tab configured to engage a tab aperture of said first side of said movable track; wherein the retaining tab extends substantially in a lateral direction of said movable track.
