SYSTEM FOR ELECTRONICALLY CONTROLLING SEAT BELT LOAD LEVELS DURING AN EVENT
First Claim
Patent Images
1. A system for electronically controlling seat belt load levels during an event, the system comprising:
- a first compression member;
a second compression member;
a seat belt webbing disposed between the first and second compression member; and
wherein the first compression member and the second compression member cooperate to apply a selectively variable compression force to the seat belt webbing.

Abstract
A system for electronically controlling seat belt load levels during an event includes a first and second compression member, and a seat belt webbing disposed between the first and second compression members. The first and second compression members may cooperate in a manner such that they may apply a selectively variable compression force to the seat belt webbing.

14. A system for electronically controlling seat belt load levels during an event, the system comprising:
-
a first compression member; a second compression member; a seat belt webbing disposed between the first and second compression member; and a controller configured to monitor a parameter indicative of a vehicle event and to generate a variable actuation signal in response thereto; and an actuator configured to receive the variable actuation signal from the controller, and, in response, to selectively urge the first compression member against the second compression member. - View Dependent Claims (15, 16, 17, 18, 19)

20. A system for electronically controlling seat belt load levels during an event, the system comprising:
-
a first compression member; a second compression member; a seat belt webbing disposed between the first and second compression member; and a controller configured to monitor a parameter indicative of a vehicle event and an attribute of an occupant, and configured to generate a variable actuation signal in response thereto; and an actuator configured to receive the variable actuation signal from the controller, and, in response, to selectively urge the first compression member against the second compression member and thereby apply a pressure to the seat belt webbing, the actuator including a piezoelectric device; and wherein the actuator is further configured to controllably relieve the pressure from the webbing.
