Title:
【発明の名称】衝撃エネルギ―を吸収する座席の脚構造
Document Type and Number:
Japanese Patent JP2520005
Kind Code:
B2
Abstract:
A front leg (1) is formed of a linear support pole rising upright from a stationary stud (8) and a rear leg (2) is formed of a lower support pole (2a) extending along a diagonal line connecting the upper end portion of the front leg and the lower end portion of the rear leg and an upper support pole (2b) extending from the upper part of the lower support pole (2a) and arching upwardly and rearwardly. Further, an energy absorbing member (12) is bridged as a diagonal member between the upper end of the front leg and the lower end of the rear leg to constitute the leg structure. This leg structure serves to absorb impact energy by antiplastic deformation force that occurs when the rear leg (2) and the member (12) receive impact beyond a predetermined value and undergo plastic deformation, and supports the seat in a support posture at the time of normal use. This leg structure can be utilized as the leg structure of seats to be fitted not only in airplanes but also in automobiles, railway vehicles, and so forth.
