US Patent 7520569 Chair with a combination back support and cover plate

A chair with a combination back support and cover plate is provided, which solves a burdensome affair that a user consistently holds up a back support folded on a seat until he or she sits on the seat, makes the back support automatically folded on the seat after use of the seat, to thereby enhance convenience of use, and prevents the back support from being unfolded upwards from the state where the back support has been folded on the seat due to wind, to thereby prevent the seat from being polluted due to dust or rainwater.
