Load transfer structure against side impact

摘要

A load transfer structure includes a seatback frame, and a load receiving member disposed on the seatback frame to contact with a side wall of a vehicle body when the side wall is moved toward a vehicle cabin by a side impact. The load receiving member includes a horizontal portion extending laterally, an inclined portion extended obliquely outward and upward from an outer end of the horizontal portion, and a curved portion provided between the horizontal portion and the inclined portion and having inner and outer concave edges. A bisector 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. Accordingly, an absorbed energy amount by the load receiving member increases.

1. A load transfer structure against a side impact, the structure comprising:
a seatback frame; 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, wherein the load receiving member includes a horizontal portion extending laterally, an inclined portion extended obliquely outward and upward from an outer end of the horizontal portion, and a curved portion that is provided between the horizontal portion and the inclined portion and whose inner edge and outer edge are formed as concave edges, respectively, and a bisector 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.
