<P>PROBLEM TO BE SOLVED: To provide a vehicle seat mounting a frame, which includes both first and second fragile parts, and which can smoothly absorb the impact energy by appropriately transmitting deformation caused by a rear side collision from the first fragile part to the second fragile part. <P>SOLUTION: The vehicle seat that has a seat back frame that is deformed when the impact load is applied. The seat back frame includes: a hole 17k as the first fragile part that is deformed when the seat back frame is deformed by the impact load; an inner fragile part 17e as the second fragile part that is deformed by transmission of the deformation of the hole 17k; and a direction regulation part 40 that regulates the direction to which the deformation of the hole 17K is transmitted so as not to come off from the direction toward the fragile part 17e from the hole 17k. <P>COPYRIGHT: (C)2013,JPO&INPIT |
