Airbag assembly
View Patent ↗In at least one embodiment, the present invention relates an airbag assembly comprising a panel having a tear seam forming at least one airbag door, and a door chute assembly comprising a laterally extending flange connected to the panel proximate the airbag door. The door chute assembly includes a chute depending from the flange away from the panel and the chute has at least one opening. The airbag assembly further comprises a door panel assembly including at least one door panel disposed within the chute and connected to the airbag door. The door panel has a downwardly depending flange having at least one projection extending laterally through the at least one opening of the chute. The airbag assembly further comprises an inflatable airbag mounted on the door chute.
1. An airbag assembly comprising;
a panel having a tear seam forming at least one airbag door;
a door chute assembly comprising a laterally extending flange connected to the panel proximate the at least one airbag door, the door chute assembly including a chute depending from the flange away from the panel, the chute having at least one opening comprising a window portion communicating with a channel portion, the channel portion having a first general width and the window portion having a second general width, greater than the first general width;
a door panel assembly including at least one door panel disposed within the chute and connected to the at least one airbag door, the at least one door panel having a downwardly depending flange having at least one projection extending laterally through the at least one opening of the chute; and
an airbag cannister assembly comprising an inflatable airbag mounted on the door chute assembly, wherein the at least one projection includes a base spaced apart from the downwardly depending flange and an arm extending between and connecting the base and the downwardly depending flange, the arm having a third general width which is roughly the same as the first general width, the window portion having a first shape and the base having the first shape and a fourth general width, the fourth general width being smaller than the second general width and greater than the first general width.
2. The airbag assembly of claim 1 wherein the chute of the door chute assembly comprises a rectangular wall.
3. The airbag assembly of claim 1 wherein the at least one projection comprises a plurality of spaced apart projections.
4. The airbag apparatus of claim 3 wherein the at least one opening comprises a plurality of spaced apart openings disposed on the chute, wherein each of the projections extends through a respective one of the openings.
5. The airbag assembly of claim 1 wherein the at least one projection cooperates with the at least one opening to inhibit the distance the at least one door panel can linearly travel during deployment of the airbag.
6. The airbag assembly of claim 5 wherein the distance the panel is allowed to travel is sufficient to enable a portion of the downwardly depending flange to extend above the panel.
7. The airbag assembly of claim 1 wherein the at least one projection cooperates with at least one the opening to maintain the door chute assembly and the at least one door panel assembly in a relative fixed arrangement while the door chute assembly and the door panel are being connected to the panel.
8. A door chute and panel assembly for use with an airbag assembly comprising a panel having a tear seam forming at least one airbag door, and an air bag cannister assembly comprising an inflatable airbag, the door chute and panel assembly comprising:
a door chute assembly comprising a laterally extending flange connectable to the panel proximate the at least one airbag door, the door chute assembly including a chute depending from the flange, the chute including a depending wall having an inner surface and an outer surface, the chute having at least one opening extending through the depending wall between the inner and outer surfaces; and
a door panel assembly including at least one door panel disposed within the chute and connectable to the at least one airbag door, the at least one door panel having a downwardly depending flange having at least one projection extending laterally through the at least one opening of the chute, the at least one opening comprising a window portion communicating with a channel portion, the channel portion having a first general width and window portion having a second general width, greater than the first general width, wherein the at least one projection includes a base spaced apart from the downwardly depending flange and an arm extending between and connecting the base and the downwardly depending flange, the arm having a third general width which is roughly the same as the first general width, the window portion having a first shape and the base having the first shape and a fourth general width, the fourth general width being smaller than the second general width and greater than the first general width.
9. The assembly of claim 8 wherein the at least one projection comprises a plurality of spaced apart projections.
10. The assembly of claim 9 wherein the at least one opening comprises a plurality of spaced apart openings disposed on the chute, wherein each of the projections extends through a respective one of the openings.
11. The assembly of claim 10 wherein the at least one projection cooperates with the at least one opening to inhibit the distance the at least one door panel can linearly travel during deployment of the airbag.
12. The assembly of claim 11 wherein the distance the panel is allowed to travel is sufficient to enable a portion of the downwardly depending flange to extend above the panel.
13. A method for manufacturing an airbag assembly, the method comprising:
providing a panel having a tear seam forming at least one airbag door;
providing a door chute assembly comprising a chute having a laterally extending flange and at least one opening comprising a window portion communicating with a channel portion, the channel portion having a first general width and the window portion having a second general width, greater than the first general width;
connecting the flange of the door chute assembly to the panel proximate the at least one airbag door; and
disposing a door panel assembly including at least one door panel disposed within the chute and connecting the at least one door panel to the at least one airbag door, the at least one door panel having a downwardly depending flange having at least one projection extending laterally through the at least one opening of the chute assembly, wherein the at least one projection includes a base spaced apart from the downwardly depending flange and an arm extending between and connecting the base and the downwardly depending flange, the arm having a third general width which is roughly the same as the first general width, the window portion having a first shape and the base having the first shape and a fourth general width, the fourth general width being smaller than the second general width and greater than the first general width.
14. A door chute and panel assembly for use with an airbag assembly comprising a panel having a tear seam forming at least one airbag door, and an air bag cannister assembly comprising an inflatable airbag, the door chute and panel assembly comprising:
a door chute assembly comprising a laterally extending flange connectable to the panel proximate the at least one airbag door, the door chute assembly including a chute depending from the flange, the chute having at least one opening comprising a window portion communicating with a channel portion, the channel portion having a first general width and window portion having a second general width, greater than the first general width; and
a door panel assembly including at least one door panel disposed within the chute and connectable to the at least one airbag door, the at least one door panel having a downwardly depending flange having at least one projection extending laterally through the at least one opening of the chute assembly, wherein the at least one projection includes a base spaced apart from the downwardly depending flange and an arm extending between and connecting the base and the downwardly depending flange, the arm having a third general width which is roughly the same as the first general width, the window portion having a first shape and the base having the first shape and a fourth general width, the fourth general width being smaller than the second general width and greater than the first general width.
