The rebound bar includes a main body and at least one shock absorbing portion. The main body is connected to one of a seat portion and a base portion of the child safety seat. The at least one shock absorbing portion combined with the main body for absorbing an impact from the backrest. The at least one shock absorbing portion can produce deformation when the rebound bar receives the impact from the backrest. Therefore, it can effectively reduce risk of injury to a child. Furthermore, a child safety seat assembly having the aforementioned rebound bar is disclosed. ## Claims ### Claim 1 A rebound bar adapted for being supported between a child safety seat and a backrest of a car seat, the rebound bar comprising: a main body connected to one of a seat portion and a base portion of the child safety seat; and at least one shock absorbing portion combined with the main body for absorbing an impact from the backrest, wherein the at least one shock absorbing portion is a sandwich structure, the at least one shock absorbing portion comprises a first lamination, a second lamination, a honeycomb component and at least one resilient component, the at least one resilient component is connected to the first lamination and the second lamination, the honeycomb component is installed between the first lamination and the second lamination and separated from at least one of the first lamination and the second lamination when the first lamination and the second lamination are unforced, and deformation of the at least one resilient component occurs before crack of the honeycomb component when the first lamination and the second lamination are forced to move close to each other. ### Claim 2 (depends on 1) The rebound bar of claim 1, wherein the main body is formed in a U shape and comprises a first segment, a second segment and a third segment, an end of the third segment is connected to an end of the first segment, another end of the third segment is connected to an end of the second segment, another end of the first segment is connected to the one of the seat portion and the base portion of the child safety seat, and another end of the second segment is connected to the one of the seat portion and the base portion of the child safety seat. ### Claim 3 (depends on 2) The rebound bar of claim 2, wherein the at least one shock absorbing portion is integrally combined with at least one of the first segment, the second segment and the third segment of the main body. ### Claim 4 (depends on 2) The rebound bar of claim 2, wherein the at least one shock absorbing portion is detachably combined with at least one of the first segment, the second segment and the third segment of the main body. ### Claim 5 (depends on 1) The rebound bar of claim 1, wherein the at least one shock absorbing portion is located a position near a connection of the main body and the one of the seat portion and the base portion of the child safety seat. ### Claim 6 A child safety seat assembly comprising: a child safety seat comprising a seat portion and a base portion; and a rebound bar supported between the child safety seat and a backrest of a car seat, the rebound bar comprising: a main body connected to one of the seat portion and the base portion of the child safety seat; and at least one shock absorbing portion combined with the main body for absorbing an impact from the backrest, wherein the at least one shock absorbing portion is a sandwich structure, the at least one shock absorbing portion comprises a first lamination, a second lamination, a honeycomb component and at least one resilient component, the at least one resilient component is connected to the first lamination and the second lamination, the honeycomb component is installed between the first lamination and the second lamination and separated from at least one of the first lamination and the second lamination when the first lamination and the second lamination are unforced, and deformation of the at least one resilient component occurs before crack of the honeycomb component when the first lamination and the second lamination are forced to move close to each other. ### Claim 7 (depends on 6) The child safety seat assembly of claim 6, wherein the main body is formed in a U shape and comprises a first segment, a second segment and a third segment, the third segment is connected to an end of the first segment and an end of the second segment, another end of the first segment is connected to the one of the seat portion and the base portion of the child safety seat, and another end of the second segment is connected to the one of the seat portion and the base portion of the child safety seat. ### Claim 8 (depends on 7) The child safety seat assembly of claim 7, wherein the at least one shock absorbing portion is integrally combined with at least one of the first segment, the second segment and the third segment of the main body. ### Claim 9 (depends on 7) The child safety seat assembly of claim 7, wherein the at least one shock absorbing portion is detachably combined with at least one of the first segment, the second segment and the third segment of the main body. ### Claim 10 (depends on 6) The child safety seat assembly of claim 6, wherein the at least one shock absorbing portion is located a position near a connection of the main body and the one of the seat portion and the base portion of the child safety seat.
