Title:
BUMPER STAY
Document Type and Number:
WIPO Patent Application WO/2007/110938
Kind Code:
A1
Abstract:
A bumper stay placed between a vehicle body and a bumper reinforcement, providing a greater amount of absorption of impact energy while reducing the peak of a crush load and less likely to buckle laterally outward of the vehicle body. The bumper stay (2) has a pair of tubular sections (2A, 2B) arranged spaced apart in the front-rear direction and a pair of wall sections (2C, 2C) arranged to connect the tubular sections (2A, 2B). The pair of tubular sections (2A, 2B) and the pair of wall sections (2C, 2C) form three tubular spaces (2x, 2y, 2z) lying in the front-rear direction, between a side member (M) and the bumper reinforcement (1). Rigidity of both the pair of tubular sections (2A, 2B) and the pair of wall sections (2C, 2C) is determined so that the pair of wall sections (2C, 2C) sink into the pair of tubular sections (2A, 2B) when an impact load acts in the front-rear direction.
