Abstract
The present invention relates to a roll over restraint system for a vehicle. The roll over restraint system includes a mattress, restraint belt section, and one or more activation sensors. The restraint belt section extends laterally across the mattress. The one or more activation sensors detect the occurrence of at least one of a vehicle declaration threshold, a vehicle attitude change threshold, or a vehicle crash and in response thereto generate a signal. The signal results in at least one pre-tensioning devices increasing the tension applied to the restraint belt section and/or inflation of the restraint belt section.
Claims16
A roll over bunk restraint system for a vehicle, comprising:
- a mattress;
- a restraint belt section provided with a first end and a second end, wherein the restraint belt section extends laterally across the mattress;
- at least one pre-tensioning device associated with the second end of the restraint belt section;
- and
- one or more activation sensors that detect the occurrence of at least one of a vehicle declaration threshold, a vehicle attitude change threshold, or a vehicle crash and in response thereto generate a signal that results in the at least one pre-tensioning device increasing the tension applied to the restraint belt section.
A method for providing a roll over bunk restraint system in a vehicle, comprising the steps of:
- providing a mattress;
- providing a restraint belt section that includes a first end and a second end, wherein the restraint belt section is configured to extend laterally across the mattress;
- providing at least one pre-tensioning device that is associated with the second end of the restraint belt section;
- and
- providing one or more sensors that are configured to detect the occurrence of at least one of a vehicle declaration threshold, a vehicle attitude change threshold, or a vehicle crash and in response thereto generate a signal that results in in the at least one pre-tensioning device increasing the tension applied to the restraint belt section.
A method for providing a roll over bunk restraint system in a vehicle, comprising the steps of:
- providing a mattress;
- providing a restraint belt section that includes a first end and a second end, wherein the restraint belt section is configured to extend laterally across the mattress and to inflate and increase a restraint force exerted by the restraint belt section on an occupant, whereby the occupant is substantially held in place on the mattress;
- and
- providing one or more activation sensors that are configured to detect the occurrence of at least one of a vehicle declaration threshold, a vehicle attitude change threshold, or a vehicle crash and in response thereto generate a signal that results in the restraint belt section inflating.
