TELESCOPE AND ADAPTIVE ENERGY ABSORPTION SYSTEM

摘要

A steering column assembly includes an upper jacket assembly received within a lower jacket assembly, and an energy absorption assembly. The energy absorption assembly includes a first energy absorption strap and a second energy absorption strap. The first energy absorption strap has a first portion defining an opening configured to receive a pin of an actuator and a second portion coupled to the upper jacket assembly. The second energy absorption strap has a third portion coupled to a telescope drive bracket and a fourth portion coupled to the upper jacket assembly.

主权项

1. A steering column assembly comprising:
a lower jacket assembly, extending along a steering column axis; an upper jacket assembly at least partially received within the lower jacket assembly, the upper jacket assembly extendable along the steering column axis relative to the lower jacket assembly; a telescope actuator assembly configured to translate the upper jacket assembly relative to the lower jacket assembly, the telescope actuator assembly comprising:
a telescope drive bracket coupled to the upper jacket assembly, anda telescope actuator disposed on the lower jacket assembly operatively coupled to the telescope drive bracket; an actuator disposed on the telescope drive bracket, having a pin configured to be in an extended position during a collapse event due to a load exceeding a predetermined load and configured to be in a retracted position during a collapse event due to a load not exceeding the predetermined load; and a first energy absorption strap having a first portion defining an opening configured to receive the pin and a second portion coupled to the upper jacket assembly; during the collapse event due to the load exceeding a predetermined load the pin is received within the opening.
