System for controlling activation of at least one restraint apparatus in a motor vehicle

Abstract

A seat base for mounting a vehicle seat to a floor of a motor vehicle includes a top member configured to be coupled to the vehicle seat, a bottom member configured to be coupled to the floor of the motor vehicle, at least one blast attenuation structure coupled to and between the top and bottom members and configured to be responsive to an under-vehicle explosion to deform and collapse at least one of the top and bottom members toward the other, a seat pulldown device configured to be responsive to an activation signal to apply a force to the top member in a direction toward the bottom member, and means responsive to the force applied by the seat pulldown device to disable or bypass the at least one blast attenuation structure so that the force applied by the seat pulldown device pulls the top member toward the bottom member.
