AI Technical Summary

Benefits of technology

The passenger airbag described in this patent has a unique inflatable cushion design that includes a longitudinal tether and a lateral tether to form a concave surface in the lower rear portion of the cushion when deployed. This design helps to limit the expansion of the cushion during inflation, and ensures a more effective deployment during a collision event. The vehicle passenger restraint system also includes a sensor, controller, and inflator device to activate the airbag and produce gas for inflation. Overall, this design improves the effectiveness and safety of passenger airbags in vehicles.

Problems solved by technology

The somewhat large number and complicated configuration of these tethers can lead to cumbersome manufacture of the airbags thereby increasing costs related to the same.

Embodiment Construction

[0008]Referring now to the discussion that follows and also to the drawings, illustrative approaches are shown in detail. Although the drawings represent some possible approaches, the drawings are not necessarily to scale and certain features may be exaggerated, removed, or partially sectioned to better illustrate and explain the present disclosure. Further, the descriptions set forth herein are not intended to be exhaustive or otherwise limit or restrict the claims to the precise forms and configurations shown in the drawings and disclosed in the following detailed description.

[0009]An exemplary passenger airbag for a vehicle passenger restraint system may include an inflatable cushion having an upper rear portion with a convex surface and a lower rear portion with a concave surface when the airbag is deployed. The airbag may also have a longitudinal tether secured to the lower rear portion to limit longitudinal expansion of the inflatable cushion and form the concave surface in th...

Abstract

An exemplary passenger airbag for a vehicle passenger restraint system may include an inflatable cushion having an upper rear portion with a convex surface and a lower rear portion with a concave surface when the airbag is deployed. The airbag may further include a longitudinal tether secured to the lower rear portion to limit longitudinal expansion of the inflatable cushion and form the concave surface in the lower rear portion.

Description

BACKGROUND[0001]Car manufacturers continue to investigate ways to improve the performance of vehicle passenger restraint systems having airbags for front seat passengers. Typical restraint systems for front seat passengers include a powerful inflator device that deploys a somewhat large airbag to rapidly occupy a generally large volume of space aft of the windshield and the dashboard. Furthermore, the front passenger airbag can have a split lobe configuration to allocate more cushioning force on an occupant's shoulders, as compared to the occupant's head. To that end, these airbags can have multiple elongated thin straps that are individually sown to various portions of the airbag in order to provide the split lobe configuration. The somewhat large number and complicated configuration of these tethers can lead to cumbersome manufacture of the airbags thereby increasing costs related to the same.[0002]A need exists for a passenger airbag that can be quickly deployed to reduce longitu...
