Backrest structure for vehicle seat, connection piece that is connected to bracket to restrict turn of connecting rod to lock release direction

摘要

The turn of a connecting rod (12) to a lock release direction is restricted by the connection of a connection piece (28) to a bracket (30) which supports the crank shaft (12a) of the connection rod. The connection piece is connected to the bracket by the deformation of a load receiving member (24) to the crank axial direction.
