A modular energy absorbing assembly 10 comprising at base 12, and at least
one energy absorbing module 14 associated with the base for accommodating
deformation of the assembly. At least some of the energy absorbing modules
have a plurality of recesses 16 defined within the base. Each of the
plurality of recesses has a floor and at least one wall extending from the
floor to the base. An intermediate segment extends between the floor and
the at least one wall. The intermediate segment has an average radius (R).
At least some of the recesses are oriented such that their floors are
substantially orthogonal to a major incident component of the impacting
force and their walls are inclined at an angle (.alpha.) to the major
incident component of the impacting force, where (0<.alpha.<45 degrees),
in order to maximize energy absorption by the wall over a given distance.
The wall at least partially collapses and at least some of the recesses
become at least partially compressed during energy absorption.
Una asamblea absorbente 10 de la energía modular que abarcaba en la base 12, y por lo menos un módulo absorbente 14 de la energía se asociaron a la base para la deformación servicial de la asamblea. Por lo menos algunos de los módulos absorbentes de la energía tienen una pluralidad de las hendiduras 16 definidas dentro de la base. Cada uno de la pluralidad de hendiduras tiene un piso y por lo menos una pared que extienden del piso a la base. Un segmento intermedio extiende entre el piso y la por lo menos una pared. El segmento intermedio tiene un radio medio (r). Por lo menos algunas de las hendiduras se orientan tales que sus pisos son substancialmente orthogonal a un componente importante del incidente de la fuerza de afectación y sus paredes están inclinadas en ángulo (el alpha.) al componente principal del incidente de la fuerza de afectación, donde (0
