ABSTRACT:
A lightweight, inexpensive folding chair may have a seat with an interference fit support bracket may be provided. The seat may have a lightweight seat member constructed of a lightweight material, such as a blow-molded plastic, that is generally supported by two such support brackets. The support brackets may be affixed to the lightweight seat member by sliding the lightweight seat member into interference engagement with the support brackets. Thus, the lightweight seat member is supported against bending when the chair is in use, in a way that does not concentrate stresses in the lightweight seat member to cause deformation and failure. The support brackets may have an enclosing shape so that the lightweight seat member is unable to move laterally or transversely out of engagement with the support brackets. The support brackets may thus have lips extending into the lightweight seat member to provide the enclosing shape. The support brackets may also have an arcuate shape to strengthen the support brackets against bending.
