Abstract
A knee airbag includes a front panel, a rear panel and an intermediate panel. The rear panel is coupled to the front panel to define an inflation chamber. The intermediate panel is disposed between the front panel and the rear panel and within the inflation chamber. The intermediate panel is connected to the rear panel by rows of first attachment points extending in a lateral direction across the knee airbag and connected to the front panel by rows of second attachment points extending in the lateral direction. The airbag includes a proximal bending area proximate a proximal end thereof.

A knee airbag comprising:
- a front panel;
- a rear panel coupled to the front panel to define an inflation chamber;
- and
- an intermediate panel between the front panel and the rear panel and within the inflation chamber, the intermediate panel connected to the rear panel by rows of first attachment points extending in a lateral direction across the knee airbag and the intermediate panel connected to the front panel by rows of second attachment points extending in the lateral direction;
- wherein the airbag includes a proximal bending area proximate a proximal end thereof, the intermediate panel being connected to each of the front panel and the rear panel within the proximal bending area, and
- wherein the airbag includes an open width along a line passing through a proximal most row of first attachments locations of the proximal bending area that is greater than a closed width along the line, and wherein the rows of first attachment points and the rows of second attachment points each include a plurality of attachment points spaced apart from one another in the lateral direction such that inflation gas can pass between adjacent attachment points.
A knee airbag comprising:

- a rear panel coupled to the front panel to define an inflation chamber;
- and an intermediate panel between the front panel and the rear panel and within the inflation chamber, the intermediate panel connected to the rear panel by rows of first attachment points extending in a lateral direction across the knee airbag and the intermediate panel connected to the front panel by rows of second attachment points extending in the lateral direction;
- wherein the airbag includes a proximal bending area proximate a proximal end thereof, the intermediate panel being connected to each of the front panel and the rear panel within the proximal bending area, and wherein the airbag at the proximal bending area has a side flow opening width along a line passing through a proximal most row of first attachments locations that is greater than 33 percent of a total width along the line, and
- wherein the rows of first attachment points and the rows of second attachment points each include a plurality of attachment points spaced apart from one another in the lateral direction such that inflation gas can pass between adjacent attachment points.
