A luggage article may include a plurality of walls together defining an outer structure of the luggage article, a wheel bracket attached to and extending from one of the walls, and a wheel attached to the wheel bracket. The wheel bracket may comprise first and second elongate arms extending along a common side of the wheel. The first and second arms may be vertically-spaced apart from one another over at least a portion of the length of the first and second arms. The configuration of the wheel bracket may result in higher shock absorption and reduced wheel noise comparative to conventional wheel brackets, and offer an improvement and alternative to conventional luggage wheel brackets.

1. A luggage article comprising: a plurality of walls together defining an outer structure of the luggage article; andone or more wheel assemblies attached to and extending from one of the walls, the one or more wheel assemblies comprising: a wheel bracket attached to and extending from one of the walls, the wheel bracket comprising a support member and a suspension member; anda wheel attached to the wheel bracket and having a central axis;wherein: the suspension member comprises a first arm and a second arm coupled separately to the support member and in a fixed relationship relative to the support member;the first and second arms extend from the central axis to the support member along a common side of the wheel and vertically-spaced apart from one another over at least a portion of the length of the first and second arms; andat least one of the first arm and the second arm resiliently deforms and bends along its length to absorb impact energy. 2. A luggage article as claimed in claim 1 wherein the first and second arms have different bending stiffness. 3. A luggage article as claimed in claim 1 wherein the first arm is positioned directly above the second arm. 4. A luggage article as claimed in claim 1 wherein the first and second arms converge toward one another as the first and second arms approach the central axis of the wheel. 5. A luggage article as claimed in claim 1 wherein the first and second arms form a cantilevered wheel mount that extends at least partially around the central axis of the wheel. 6. A luggage article as claimed in claim 5 wherein the cantilevered wheel mount is positioned within a hub insert, and wherein a wheel axle passes through the hub insert. 7. A luggage article as claimed in claim 1 wherein the first and second arms are solid or single-stranded wire. 8. A luggage article as claimed in claim 1 wherein the first arm is arcuate, and wherein the second arm is straight or substantially straight. 9. A luggage article as claimed in claim 1 wherein the first and second arms are formed as a single component. 10. A luggage article as claimed in claim 1 wherein the support member receives end portions of the first and second arms, and wherein the end portions are vertically-spaced apart from one another. 11. A luggage article as claimed in claim 10 wherein the support member defines a wheel abutment that is adapted to contact a circumferential surface of the wheel, thereby limiting the wheel travel of the wheel and the resilient deformation of the first and second arms. 12. A luggage article as claimed in claim 10 wherein the first and second arms each define a notch, and wherein the support member includes a support member insert having multiple prongs that engage the notches to interlock the first and second arms to the support member. 13. A luggage article as claimed in claim 1 wherein the wheel bracket further comprises third and fourth arms that extend along an opposing side of the wheel relative to the first and second arms. 14. A luggage article as claimed in claim 13 wherein at least the third and fourth arms are formed as a single component. 15. A luggage article as claimed in claim 1 wherein the wheel bracket and the wheel form part of a spinner wheel assembly, the wheel bracket including a rotation axis perpendicular to the central axis of the wheel. 16. A luggage article as claimed in claim 1, wherein the first arm resiliently deforms and bends along its length to absorb impact energy. 17. A wheel assembly for a luggage article, the wheel assembly comprising: a wheel bracket comprising a support member and a suspension member; anda wheel attached to the wheel bracket and having a central axis;wherein: the suspension member comprises a first arm and a second arm coupled separately to the support member and in a fixed relationship relative to the support member;the first and second arms extend from the central axis to the support member along a common side of the wheel and vertically-spaced apart from one another over at least a portion of the length of the first and second arms; andat least one of the first arm and the second arm resiliently deforms and bends along its length to absorb impact energy. 18. The wheel assembly of claim 17 wherein the first and second arms have different bending stiffness. 19. The wheel assembly of claim 17 wherein the first and second arms are solid or single-stranded wire. 20. The wheel assembly of claim 17 wherein the first and second arms form a cantilevered wheel mount that extends at least partially around the central axis of the wheel. 21. The wheel assembly of claim 17 wherein the support member receives end portions of the first and second arms and wherein the end portions are vertically-spaced apart from one another.
