5. The support base according to claim 4 , wherein the cushioning portion includes a slit connected with the first and second holes.
6. The support base according to claim 4 , wherein the portion of the arm further includes a third hole, the second hole is located between the first and third holes, and a second cushioning portion is defined between the second hole and the third hole.
7. The support base according to claim 3 , wherein the cushioning portion includes a cushioning pad made of cast aluminum.
8. The support base according to claim 1 , wherein the cushioning portion is made of a material of the adjustable arm.
9. The support base according to claim 3 , wherein the fastener breaks at least partially the cushioning portion when collision occurs.
10. The support base according to claim 3 , wherein the adjustable arm is movable along a lengthwise axis of the shell body to adjust a length at which the latch assembly extends from a rear of the shell body.
11. The support base according to claim 3 , wherein the arm extends transversally along a width of the shell body, and the latch assembly is connected with the arm.
12. The support base according to claim 11 , wherein the shell body includes two openings through which the arm extends outward from the shell body, the openings being larger than a width of the arm.
13. The support base according to claim 3 , wherein the shell body includes a fixed tubular anchor that is connected with the arm, and the cushion structure is disposed adjacent to a joint region of the arm with the tubular anchor.
14. The support base according to claim 1 , wherein the arm includes a first and a second segment connected with each other, and the cushion structure includes a cushioning pad that is affixed in an overlapping region between the first and second segments.
15. The support base according to claim 1 , wherein the arm extends transversally along a width of the shell body, and the cushion structure includes a cushioning pad affixed with the shell body at a location between the arm and an internal sidewall of the shell body.
16. A child safety seat assembly comprising:
the support base according to claim 1 ; and
a child safety seat arranged on the support base.
17. A support base for a child safety seat, comprising:
a shell body;
an arm connected with the shell body;
a latch assembly provided at an end of the arm, the latch assembly being operable to fixedly attach the shell body with an anchorage fixture of a vehicle; and
a cushion structure disposed respectively adjacent to the arm and the latch assembly, wherein the cushion structure is operable to allow a cushioned displacement of the shell body along with the arm relative to the latch assembly when the child safety seat is subject to collision.
18. The support base according to claim 17 , wherein the cushion structure includes a portion of the arm having a first hole and a solid cushioning portion adjacent to each other, the arm is connected with the shell body, and a fastener passes through the first hole and is in contact with the cushioning portion, the fastener pushing against the cushioning portion when collision occurs.
19. The support base according to claim 17 , wherein the cushioning portion is affixed with the shell body.
