Benefits of technology

The patent describes a seat belt system for airplanes or helicopters that uses a spool assembly with a trigger assembly that locks the seat belt. The system also has an adjustable payout assembly that determines the maximum length of the seat belt that can be pulled out before stopping. The trigger assembly can be triggered by sensors and can automatically unlock after a triggering event or be manually unlocked. The technical effect of this invention is to provide a reliable and flexible safety measure for occupants of vehicles in the event of a sudden stop or other emergency situations.

Problems solved by technology

However, some vehicles, such as helicopters or air cargo delivery planes may require an occupant to move about the interior of the vehicle.
Intentional or unintentional vehicle motion such as turbulence or banking into a turn can cause an occupant to lose their balance or be thrown about the vehicle's interior.
In some open vehicles such as rescue helicopters and military cargo planes, the occupant is in further danger of being thrown from the vehicle.

Abstract

In a preferred embodiment, a restraint system is described for restraining a standing occupant in a vehicle such as a plane or helicopter. The restraint system includes a webbing strap that winds and unwinds from a spool assembly. The spool assembly includes a trigger assembly that locks a spool from rotation, a manual release assembly for manually releasing the trigger assembly and lock, and an adjustable payout assembly that determines the maximum length that the webbing strap can be pulled out before stopping (i.e., the number of rotations of the spool). The trigger assembly can trigger the lock assembly from one or more sensors. Further, the trigger assembly can be arranged to automatically unlock after a triggering event, manually unlocked after a triggering event or a combination of the two for different sensors.

Description

RELATED APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 12 / 372,658 filed Feb. 17, 2009 entitled Restraint System, which claims priority to U.S. Provisional Application Ser. No. 61 / 028,753 filed Feb. 14, 2008 entitled Crew Restrain System, both of which are hereby incorporated herein by reference in their entireties.BACKGROUND OF THE INVENTION[0002]Vehicles, such as aircraft, often include restraint systems to prevent occupants from unwanted movement and injury. Typically, these restraint systems restrain the occupant from movement by releasably strapping the occupant to a chair or similar vehicle furniture.[0003]However, some vehicles, such as helicopters or air cargo delivery planes may require an occupant to move about the interior of the vehicle. Intentional or unintentional vehicle motion such as turbulence or banking into a turn can cause an occupant to lose their balance or be thrown about the vehicle's interior. In some open vehicles suc...
