One general aspect includes a deployable containment system for a vehicle roof panel, the system including: a pair of guide channels proximate to an opening through the vehicle roof panel, each guide channel of the pair having a first end and a second end; a housing mounted to the first end of the pair of guide channels. The deployable containment system also includes a shield configured to deploy from the housing and travel along the pair of guide channels so as to cover at least a portion of the opening. The deployable containment system also includes an actuator disposed proximate to the pair of guide channels, the actuator configured to deploy the shield from the housing after a deployment event.

Deployable roof containment system and method

A deployable containment system of a vehicle includes a pair of guide channels that surround an opening facing one of a forward direction of travel of the vehicle and a backward direction of travel of the vehicle. Each of the guide channels has a first end and a second end. A housing is mounted to the first ends of the guide channels. A shield is configured to: deploy from the housing; travel along the guide channels toward the second ends of the guide channels; and cover at least a portion of the opening, An actuator is configured to, in response to being triggered, deploy the shield from the housing and move the shield along the guide channels toward the second ends of the guide channels.

Front and rear deployable containment system

An occupant restraint system of a vehicle includes a roof rail airbag that is located at a roof rail of the vehicle and above a door of the vehicle and that is configured to deploy in an outboard direction. A deployment device, when triggered, deploys the roof rail airbag. An actuator, when triggered, actuates a deployable reaction surface (i) from a first state where the deployable reaction surface is stowed behind interior door trim and does not block any part of a window opening of the door when viewed from inboard of the deployable reaction surface (ii) to a second state where the deployable reaction surface blocks at least a portion of the window opening of the door when viewed from inboard of the deployable reaction surface.

Systems and methods for deployable reaction surface for roof rail airbag system

A test apparatus collects performance data for a seat belt system having components providing operating stages of pre-tensioning, locking, and load limiting of the seat belt. A bench plate mounts the components of the seat belt system and includes first and second pulleys spaced apart on the bench plate and having the seat belt extending horizontally therebetween. At least one load sensor senses the load experienced by the seat belt. A resistor engages the seat belt between the first and second pulleys and pulls downwardly to introduce slack in the seat belt. An impactor mass is suspended above the seat belt and is released to free-fall onto the seat belt and impose a load on the seat belt simulating the load of a seated occupant being imposed on the seat belt. A control module energizes the pre-tensioning stage and a plotter records force versus time performance data.
