US Patent 10279707 Vehicle seat

A vehicle seat comprises a seat cushion, seatback, a cushion side frame, a rod, a seat supporting member, and a coupling bracket. A portion of the cushion side frame and a portion of the coupling bracket are overlapped such that the cushion side frame is located outside the coupling bracket. The cushion side frame and the coupling bracket comprise a through-hole that extends along a seat-width axis through the overlapped portion of the cushion side frame and the coupling bracket. The rod is inserted into the through-hole and has a flare outer diameter outside the cushion side frame that is larger than the diameter of the through-hole in the cushion side frame.
