Support structure for roof reinforcement

摘要

A support structure comprises a first portion for sliding attachment to a seat having a front, a back, and two sides, and a second portion connected to the first portion at a substantially right angle. The first portion has a hollow cross-sectional shape with an asymmetrical material distribution through the plane of the cross section, the material distribution placing more of the material comprising the first portion toward the sides of the vehicle seat. The support structure is adapted for attachment to the seat and is adapted to be activated to extend in a substantially vertical direction upwardly from the seat. The first portion has an arc shape along its length so that when the support structure is activated the second portion is supported by the first portion at a desirable angle for bracing against an impact force direction that is typical of vehicle rollover.
