Description

Side air curtain installing support and vehicle

Technical Field

The invention relates to an automobile part, in particular to a side air curtain mounting bracket and a vehicle.

Background

The automobile safety air bag is of great importance for protecting passengers, and the performance of the safety air bag directly determines the safety level of a vehicle. The air bag arranged on the side wall of the vehicle is in a curtain shape after being unfolded, and is also called a side safety air curtain in engineering.

The side safety air curtain is fixed on the vehicle body by screws, and when the vehicle is exploded, air is filled in the air bag which is spread on the side wall of the vehicle body in a curtain shape, so that passengers are protected from being impacted. This arrangement has the following problems: first, the air curtain sometimes penetrates into the gap between the interior trim part and the vehicle body panel when deployed. Second, the trim itself may have sharp corners that can be scratched when the curtain is deployed, resulting in breakage. Third, the decoration in the automobile body needs to be fixed in the mounting hole of reserving on the automobile body usually, because the existence of safe gas curtain, can occupy some automobile body spaces, the space that is used for assembling the decoration on the automobile body side wall can reduce, can occupy the mounting hole of decoration sometimes, can lead to the unable fixed or the not good phenomenon of cooperation with peripheral part of decoration. Fourthly, because the materials of a plurality of decorating parts on the side wall of the automobile body are different, the fixing directions and the fixing modes of a plurality of parts are also different, and the condition that the gap break difference and the over difference between the parts affect the attractiveness can be generated.
