Abstract

A knee bolster system is capable of automatic extension and retraction during specified scenarios that are determined based on sensor input. A microprocessor electrically controls an actuator capable of extending at least one telescoping mechanism which is rigidly engaged to a knee bolster pad located in the lower portion of an instrument panel at knee height to an occupant. Each telescoping mechanism houses a plowing mechanism. This plowing mechanism generates reaction forces during actuation.
