SEAT RECLINING SYSTEM

摘要

A seat reclining system for an automotive vehicle, arranged to achieve its weight-lightening. The seal reclining system comprises a locking mechanism having first and second axial sides. An arm plate is provided such that the first axial side of the locking mechanism is connected to the arm plate. A seat back of a vehicle seat is connected to the arm plate. A base plate is provided having first and second surfaces which are opposite to each other. The base plate includes an installation portion through which the base plate is connected to a vehicle floor. The base plate further includes a fixed portion having the first surface to which the second axial side of the locking mechanism is connected. Additionally, a reinforcement plate is provided including a main body section having first and second surfaces which are opposite to each other. The reinforcement plate further includes a flange section integral and extended from the main body section. The flange section extends generally perpendicular to a plane which passes through a first position located in front of the fixed portion of the base plate and a second position located behind the installation portion of the base plate. The plane is perpendicular to the surfaces of the base plate. The reinforcement plate is fixed to the base plate in a state where the first surface of the main body section is in contact with the second surface of the base plate.
