Abstract
The present disclosure relates to a side mounting seat with an increased area that a vibration welding pressing jig directly presses. It is important to minimize an unpressed area by maximally securing an area that a welding jig may directly press in order to simultaneously secure weldability and exterior quality. The present disclosure provides a structure in which a hollow space in a side mounting seat is reduced by minimizing a necessary area of a hollow doghouse of the side mounting seat of each of both sides of a PAB chute, and a pressing target surface is added to allow the welding jig to press an idle region which is conventionally not directly pressed by the welding jig.
Claims18
A side mounting seat, on which a bracket of a passenger airbag (PAB) module including a PAB is mounted, of a PAB chute which is vibration-welded to a crash pad panel by a vibration pressing welding jig, the side mounting seat comprising:
- a doghouse having a hollow space between a lower portion of the side mounting seat and a base surface of the PAB chute and including an opening at one side of the doghouse;
- and
- a direct pressing target surface extending at a right angle on a closed wall disposed at an opposite side of the opening of the doghouse, and located at a position higher than the base surface of the PAB chute, such that the direct pressing target surface is directly pressed by the vibration pressing welding jig when the PAB chute is vibration-welded to the crash pad panel.
A method of manufacturing a passenger airbag (PAB) chute which includes a side mounting seat on which a bracket of a PAB module including PAB is mounted and is vibration-welded to a crash pad panel by a vibration pressing welding jig, the method comprising:
- forming a doghouse between a lower portion of the side mounting seat and a base surface of the PAB chute, the doghouse including an opening at one side of the doghouse;
- and
- forming a direct pressing target surface extending at a right angle on a closed wall disposed at an opposite side of the opening of the doghouse, the direct pressing target surface being located at a position higher than the base surface of the PAB chute, such that the direct pressing target surface is directly pressed by the vibration pressing welding jig when the PAB chute is vibration-welded to the crash pad panel.
