A retention block may be pivotably coupled to the first bracket. A second bracket may be slidingly coupled to the housing. The first bracket may be coupled to the second bracket via a spring. The first bracket and the second bracket may be configured to attenuate in response to a cargo deck bending during transportation of cargo in an aircraft. ## Claims ### Claim 1 A cargo restraint assembly comprising: a housing having a first end wall, a second end wall, a first base, and a second base, the first end wall extending from the first base to the second base, the second end wall extending from the first base and the second base, the first end wall disposed opposite the second end wall; a first bracket disposed between the first end wall and the second end wall, the first bracket slidably coupled to the first end wall and the second end wall; and a first guide block pivotably coupled to the first bracket. ### Claim 2 (depends on 1) The cargo restraint assembly of claim 1, further comprising a second bracket disposed between the first end wall and the second end wall, the second bracket slidably coupled to the first end wall and the second end wall. ### Claim 3 (depends on 2) The cargo restraint assembly of claim 2, further comprising a second guide block pivotably coupled to the second bracket. ### Claim 4 (depends on 3) The cargo restraint assembly of claim 3, further comprising a spring disposed between the first bracket and the second bracket. ### Claim 5 (depends on 2) The cargo restraint assembly of claim 2, wherein the first bracket and the second bracket each comprise an H-shape. ### Claim 6 (depends on 1) The cargo restraint assembly of claim 1, further comprising a first shaft and a first pin, wherein the first bracket comprises a first flange and a second flange, wherein the first flange is disposed adjacent to the first end wall, wherein the second flange is disposed adjacent to the second end wall, wherein the first shaft extends from a first slot in the first end wall through the first flange through the second flange and through a second slot in the second end wall, and wherein the first pin extends from the a third slot in the first end wall through the first flange. ### Claim 7 (depends on 6) The cargo restraint assembly of claim 6, wherein the first guide block comprises a lateral retention portion, a vertical retention portion, a first wing portion and a second wing portion, the lateral retention portion extending from the first flange to the second flange, the vertical retention portion extending from the lateral retention portion in a lateral direction, the first wing portion extending in a longitudinal direction away from the lateral retention portion past the first end wall, and the second wing portion extending in a negative longitudinal direction away from the lateral retention portion past the second end wall. ### Claim 8 (depends on 1) The cargo restraint assembly of claim 1, further comprising a first shaft extending from a first flange of the first bracket to a second flange of the first bracket, wherein the first guide block is configured to rotate about the first shaft. ### Claim 9 (depends on 8) The cargo restraint assembly of claim 8, further comprising a torsion spring coupled to the first shaft and the first guide block. ### Claim 10 A cargo loading system, comprising: a cargo deck; a first tray extending longitudinally along the cargo deck; a second tray disposed laterally adjacent to the first tray, the second tray extending longitudinally along the cargo deck; a cargo restraint assembly disposed between the first tray and the second tray, the cargo restraint assembly coupled to the cargo deck, the cargo restraint assembly comprising: a housing; a first bracket slidingly coupled to the housing; a second bracket slidingly coupled to the housing; a spring extending between the first bracket and the second bracket; a first guide block pivotably coupled to the first bracket; and a second guide block pivotably coupled to the second bracket. ### Claim 11 (depends on 10) The cargo loading system of claim 10, wherein the housing comprises a first end wall, a second end wall, a first base, and a second base, the first end wall extending from the first base to the second base, the second end wall extending from the first base and the second base, the first end wall disposed opposite the second end wall, wherein the first base and the second base are coupled to the cargo deck. ### Claim 12 (depends on 11) The cargo loading system of claim 11, wherein the first end wall and the second end wall comprise a plurality of slots, and wherein the first bracket and the second bracket are slidingly coupled to the plurality of slots. ### Claim 13 (depends on 12) The cargo loading system of claim 12, wherein the cargo restraint assembly further comprises a first shaft, a first pin, and a second pin, wherein the first bracket and the second bracket each comprise a first flange and a second flange, wherein the first flange is disposed adjacent to the first end wall, wherein the second flange disposed adjacent to the second end wall, wherein the first shaft extends from a first slot in the plurality of slots through the first flange and through the second flange into a first slot in the plurality of slots in the second end wall, wherein a first pin extends from a second slot in the first end wall through the first flange, and a second pin extends from the second flange through a second slot in the plurality of slots in the second end wall. ### Claim 14 (depends on 13) The cargo loading system of claim 13, wherein the first guide block and the second guide block each comprise a lateral retention portion, a vertical retention portion, a first wing portion and a second wing portion, the lateral retention portion extending from the first flange to the second flange, the vertical retention portion extending from the lateral retention portion in a lateral direction, the first wing portion extending in a longitudinal direction away from the lateral retention portion past the first end wall, and the second wing portion extending in a negative longitudinal direction away from the lateral retention portion past the second end wall. ### Claim 15 (depends on 10) The cargo loading system of claim 10, wherein the first bracket, the second bracket, the first guide block and the second guide block are configured to laterally attenuate in response to the cargo deck bending. ### Claim 16 (depends on 10) The cargo loading system of claim 10, wherein the first bracket and the second bracket each comprise an H-shape. ### Claim 17 (depends on 10) The cargo loading system of claim 10, further comprising a first shaft extending from a first flange of the first bracket to a second flange of the second bracket, wherein the first guide block is configured to rotate about the first shaft. ### Claim 18 (depends on 17) The cargo loading system of claim 17, further comprising a torsion spring coupled to the first shaft and the first guide block. ### Claim 19 A method of attenuating a cargo retention assembly, the method comprising: translating a first guide block and a second guide block in a lateral direction away from each other via a spring in response to a cargo deck bending; and translating the first guide block and the second guide block towards each other in response to the cargo deck no longer bending. ### Claim 20 (depends on 19) The method of claim 19, wherein the first guide block and the second guide block are slidingly coupled to a housing via a first bracket and a second bracket, and wherein the spring is disposed between the first bracket and the second bracket.
