Problems solved by technology
However, the existing instrument panel, especially the leather-covered luxury car instrument panel, due to the technical difficulties such as the weakening of the leather, the airbag door structure is still mostly a seamed open airbag
This seamed airbag door structure will not only strongly vibrate the air around the gap when the airbag explodes, thereby causing certain safety hazards to the occupants in the car, but also the seamed airbag door structure will affect the overall sense of the instrument panel in the car and car interior beauty

Embodiment Construction
[0021] Such as figure 1 , 2 As shown, the leather multi-layer seamless airbag door includes an airbag frame 2, an instrument panel frame 1, a foam layer 3, a leather layer 4, a non-woven fabric sticker 5 and a three-dimensional non-woven fabric layer 6, and the airbag frame 2 is riveted on On the instrument panel frame 1, there are foam layer 3, non-woven fabric sticker 5, three-dimensional non-woven fabric layer 6 and leather layer 4 in sequence from outside to inside. Its manufacturing method comprises the following steps:
[0022] (1) riveting the airbag frame 2 to the instrument panel frame 1 with rivets;
[0023] (2) Foaming the area of the airbag door hole 10 to produce an instrument panel skeleton 1 with a foam layer 3;
[0024] (3) Place two three-dimensional non-woven fabrics on the template, one of which is in the shape of the airbag door hole 10, the two three-dimensional non-woven fabrics can form a whole, and the joint line between the two forms a weakening l...

The invention discloses a method for manufacturing a hidden seamless airbag door of a leather multi-layer automobile dashboard. In the method, a U-shaped weakening line arranged on a leather layer and the weakening line arranged on the upper surface of a three-dimensional non-woven layer can smoothly pop an airbag in a given time after the airbag bursts a metal airbag frame and a foamed area, so that the security of people in an automobile can be timely protected. The product manufactured by the method has high-grade and attractive appearance; and the whole dashboard has better handfeel, higher structural integrity and higher performance in airbag bursting tests so as to better protect the security of the people in the automobile.
Description
technical field [0001] The invention relates to a method for manufacturing an air bag door on an automobile instrument panel, in particular to a method for manufacturing a leather multi-layer seamless air bag door on an automobile instrument panel. Background technique [0002] Car airbag system (Supplermental Restraint System, referred to as SRS) is a kind of auxiliary protection system. Generally speaking, the airbag at the driver's place is stored in the steering wheel pad. Therefore, when some high-end foreign cars were marked with " SRS" or "Airbag", you can know that the car is equipped with airbags. [0003] As people pay more and more attention to the safety performance of vehicles, the relevant state departments attach great importance to the application of automobile safety assembly, and the popularization of automobile airbag system technology, many domestic vehicles are now equipped with airbags, and the installation position of the airbags is also important. No...
