STRUCTURE OF SEAT FOR MOVING BACKWARD

摘要

PURPOSE: Structure of a seat for moving backward is provided to reduce the shock applied to an air bag or a structure by making a seat promptly move backward in a crash or a collision. CONSTITUTION: In the structure of a seat(2), a first path(11) inserted with a first piston(21) is moved by the gas. A second path(12) is moved by a second piston(22) combined with a seat cable(1) mounted on the bottom face of the seat with the pressurization of the first piston. A gas generator(16) emitting the gas to the first piston by an ignition unit(15) is formed at the end of the first path of a cylinder(10) consisting of a corrugated path(13). A damper(17) for reducing the shock of the seat is formed at the end of the second path.
