<p>A load transfer structure (25) against a side impact includes a seatback frame (5), and a load receiving member disposed on the seatback frame to contact with a side wall of a vehicle body and to receive an impact load when the side wall of the vehicle body is moved toward a vehicle cabin by a side impact. The load receiving member includes a horizontal portion (25a) extending laterally, an inclined (25b) portion extended obliquely outward and upward from an outer end of the horizontal portion, and a curved portion (25d) that is provided between the horizontal portion and the inclined portion and whose inner edge and outer edge are formed as concave edges (25f), respectively, A bisector (X) of an angle between straight edges continued from both ends of the outer concave edge and a bisector of an angle between straight edges continued from both ends of the inner concave edge intersect with each other in the curved portion. According to the load transfer structure, stress tends to concentrate to the curved portion and thereby buckling in the middle of the inclined portion is suppressed. As a result, in the load transfer member, buckling distortion doesn't occur at the inclined portion, but bent deformation occurs at the curved portion, and thereby an absorbed energy amount by the load receiving member increases.</p> |
