Title:
IMPACT-ABSORBING MEMBER
Document Type and Number:
WIPO Patent Application WO/2019/130420
Kind Code:
A1
Abstract:
This impact-absorbing member has: a hat-shaped member having a hat top section; and a plate-shaped member facing the hat top section. The hat top section and/or the plate-shaped member has provided on the wall section thereof a deformation-inducing section. The deformation-inducing section has: a first high-strength section provided in the wall section and having relatively high buckling resistance; and a pair of low-strength sections which have relatively low buckling resistance and which, when viewed in a longitudinal direction, are provided on both sides of the first high-strength section so as to sandwich the first high-strength section therebetween. The impact-absorbing member also has, when viewed in the longitudinal direction, a pair of second high-strength sections arranged on both sides of the deformation-inducing section so that each of the pair of second high-strength sections is adjacent to one of the pair of low-strength sections, respectively, and the pair of second high-strength sections have relatively higher buckling strength than the low-strength sections.
